7 5. Description 5. Description The Entero ESC emergency system controller is the main system controller in a voice alarm system, which monitors all connected low impedance & 50/100 V loudspeaker lines (both A&B lines), zone & backup amplifiers, emergency paging panels and AC & DC power sources. It includes pre-recorded messages of which two can be played simultaneously, routed to different outputs. Any monitored fault will be indicated by the General Error or System Fault indicator on the front panel and internal buzzer, some by means of additional information indicated on the Graphic Display, and by multiple Error output relay contacts. Power, System Fault, General Error and Alarm status are located on the front panel. The system design and settings are stored on a removable memory chip Expansion of the 4 outputs zones up to 12 outputs (using 2 expansion cards) in one unit. Up to 32 ESC units can be used in one voice alarm system to create up to 384 alarm zones, each with an A and B loudspeaker line. Multiple Fire Panels, Evacuation panels or Fire Detections System interfaces can be connected to meet the installation/system requirements. The ESC unit can be powered from 230 Vac and from 48 Vdc power supplies when redundant operation is required. System integrity: The Entero Voice Alarm system will detect any fault within 100 seconds and will react on these accordingly. The system features advanced functionality to maintain operating requirements, which limits the consequences of faults to ensure maximum audibility and intelligibility of announcements during emergency situations: Monitoring of loudspeaker lines using adaptive line monitoring to increase the reliability of the line monitoring, which reduces wrong failure reports e.g. due to temperature changes A & B loudspeaker configuration to maintain audibility of announcements in an alarm zone: if 1 line fails only a 50% reduction of SPL occurs, while coverage can still be maintained Possibility to connect multiple A & B loudspeakers lines per amplifier channel to increase overall coverage of large zones Monitoring of amplifiers each amplifier channel is measured independently: if a channel fails it will be substituted by an available backup amplifier channel Multiple backup amplifiers all 12 outputs of the Entero ESC unit can be covered by 1 backup amplifier channel > to increase the integrity of the system up to 3 backup amplifier channels can be connected to a single Entero ESC unit covering all 12 zones (1 backup amp for each 4 zones) Monitoring of AC mains power supply each individual system component monitors the AC mains power supply and has the possibility to switch to 48Vdc when its own AC connection fails Emergency power supply certified according EN54-4: covers the complete system during AC mains loss, while maintaining output power keeping SPL level(s) unaffected. Energy Save Mode reduces the Idle current consumption of the batteries during an AC mains loss; saves available battery power capacity which can result in possibly longer duration of emergency situation at full power. NOTE: refer to local system requirements for minimum duration required for Idle and Full power operation. Monitoring of control inputs connection to all control inputs are monitored for open line and short circuits Redundant connection (optional) between ESC units & Emergency panels option to have a second connection between units which ensures an emergency call can still be made if the main connection fails Multiple inputs to connect emergency panels inputs are independently monitored, if 1 input fails an emergency call can still be made on an emergency panel connected to the other input Multiple simultaneous announcement of pre-recorded messages into different zones increases the effectiveness of the announcement to the people; when the message storage fails the emergency microphones are still available; when multiple Entero ESC units are linked to each other and the message storage in the Master unit fails, all Slave units will switch to their own internal message storage so announcement can still be heard in the alarm zones connected to the slave units 7

12 9. Expansion cards 9. Expansion cards * NOTE: to install an expansion card, the unit needs to be opened. Make sure to first turn off the power of the unit before opening and installing an expansion card! 9.1 Entero ESC 4x4 zone expansion card (optional) Used to expand an ESC unit with 4 audio/alarm zones, auxiliary output and 1 back up amplifier (optional). Up to two 4x4 zone expansion cards can be added to a single ESC unit. The auxiliary output can be linked to any of the 4 outputs. This output will not be monitored, but will be muted during an evacuation. As an example: this output can be used to drive a separate speaker system, or a subwoofer used in addition to the installed emergency loudspeakers. Technical specifications: Line Inputs Line Outputs Amplifier inputs Loudspeaker A/B outputs 4x Audio : 0 db, balanced. Range: -90 to +6 db 4x Audio, 1x Auxiliary, 1x Backup amp : 0 db, balanced. Range: -90 to +6 db 4x Zone amplifier / 1x Backup amplifier Each output (sum of A+B): 100 V/8 A max, minimum monitored load: V To install a 4x4 zone expansion card: turn the power off, remove the top cover and the appropriate blind plate at the back of the ESC unit. Take care during installation of the card: the pin headers on the card and on the main board are fragile and bend easily make sure these are all straight before inserting the card. Fix the card to the main board with 4 screws. Turn ON the power of the ESC (before the top cover is placed back): a green LED on the 4x4 zone expansion card will illuminate, which indicates the card is installed correct; if this LED does not illuminate, quickly turn OFF the power > the card is not installed correctly. Carefully remove the card again to ensure all pin headers are still ok, after that re-install the card and ensure the green LED is illuminated before the top cover is placed back.see Appendix A & B for amplifier & backup amplifier connections and Appendix J for more information on the expansion card headers. 9.2 Entero ESC zone controller card (optional) 12 The zone controller card allows control of audio inputs 1-4 (only), which can be routed to output 1-4 (only), including volume control. Up to 4 Bose CC-4 wall controllers can be connected. This card does not influence the emergency paging routing. Each ESC can be expanded with 1 zone controller card.

13 9. Expansion cards Make sure to carefully install the zone controller card and the small back plate at the back (to cover the message cards). Turn the power off before opening the unit! See Appendix J for more information on the expansion card headers.

14 10. Entero ESC redundancy modules (optional) 9.3 Entero ESC ethernet card (optional) Instead of using the USB port, one can connect to the ESC unit using a Lan connection which can be used to setup the system during installation mode or for monitoring purposes. The ESC can be expanded with 1 Ethernet card. Technical specifications: Inputs Network speed Protocol RJ45 cat 5 input 10/100MBit Full/Half Duplex TCP/DHCP Make sure to carefully install the Ethernet card. Turn the power off before opening the unit! See Appendix J for more information on the expansion card headers. NOTE: When Ethernet card is installed a green LED, next to the Ethernet/RJ45 connector, is blinking. This RJ45 connector is pre-mounted in each ESC unit and without Ethernet card installed this connector has no function. 10. Entero ESC redundancy modules (optional) Can be used for redundant connection between two main units, using Cat5e/6 cabling. If the 1st Cable (Line A) fails, these modules switch to the 2nd cable (Line B), so communication between 2 units is maintained. A set of these modules is needed between every 2 units in the system. Line B Line A Unit A Unit B 11. Emergency panels Master module Slave module Refer to the redundancy module installation guide for more information & connection instructions. All emergency panels are connected to 1 of the 2 emergency panel busses on the ESC unit (Master or Slave). Each bus provides power to the connected panels. When multiple panels are connected, it is possible to power each panel separately by connecting to the systems battery charger directly. Up to 32 emergency panels can be connected to the 32 panel busses of an ESC unit. An activated emergency panel or emergency signal input will override music playing in the selected outputs. Priority of a panel is determined by the panel type setting and its communication address, see chapter 11.5 for more information about priority handling & settings. 14 NOTE: when connecting multiple emergency panels to bus 1 & 2, please take the maximum current (500 ma) into account. See also chapter on power consumption of emergency panels and expansion cards.

15 11. Emergency panels 11.1 Entero fire panel (FP): The fire panel is used to manually activate emergency announcements using a microphone or pre-recorded messages. With its highest priority in the system (when connected to the Master ESC unit) it will override any emergency message generated by any other Evacuation panel, Fire Detection System interface or External Audio input. It allows to select (groups) of zones using the ABCD buttons. These ABCD buttons can also be programmed for additional message selection. System errors, alarm, power supply (AC & DC) and panel status will be indicated using LEDs. The Fire panel is housed in a closed enclosure and can be located near the fire man s entrance of a building. If required it can be extended with an Entero FP/EP zone expansion module, which allows selection of more (groups of) zones. Optional accessory cards like 24 Vdc input control, relay contact outputs & flash light control are available. Hand-held microphone talking distance: 10 cm. 10 cm Fire panel including a zone expansion module Status indicators: 230 Vac green led indicates presence of 230 Vac 48 Vdc green led indicates presence of 48 Vdc ALARM red led to indicate an activated emergency message ERROR yellow led & buzzer to indicate an error in the system Panel disabled yellow led indicates 'user disabled' when ON.

See appendix C for more info. 15

16 11. Emergency panels 11.2 Entero evacuation panel (EP) The evacuation panel can used to manually activate emergency announcements using a microphone or pre-recorded messages. It has the 2nd highest priority in the system and will override any emergency message from the external signal input or messages activated by the Fire Detection System interface. It allows to select (groups) of zones using the ABCD buttons. These ABCD buttons can also be programmed for additional message selection. System errors, alarm, power supply (AC & DC) and panel status will be indicated using LEDs. The evacuation panel is housed in a desktop enclosure. If required one Entero FP/EP zone expansion module can be used to expand the evacuation panel. For more zone buttons or 19 rack mount an optional larger housing is available which can house the main panel and up to 4 zone expansion modules (or up to 6 zone expansion modules only). Optional accessory cards like 24 Vdc input control, relay contact outputs & flash light control are available. Gooseneck microphone talking distance: 25 cm. 25 cm Evacuation panel including a zone expansion card Status indicators: 230 Vac green led indicates presence of 230 Vac 48 Vdc green led indicates presence of 48 Vdc ALARM red led to indicate an activated emergency message ERROR yellow led & buzzer to indicate an error in the system Panel disabled yellow led indicates 'user disabled' when ON.

See appendix C for more info.

17 11. Emergency panels 11.3 Entero fire detection system interface (FDS) The FDS interface has the lowest priority in the system and is located inside or near the Fire Detection/Alarm System. When the Fire Alarm system is triggered (e.g. by a smoke detector) it will trigger 1 or more (contact closure) inputs of the FDS interface. The FDS interface will communicate with the emergency system controller and emergency messages are activated and routed to the pre-programmed outputs. The FDS interface can be expanded with an Entero FDS zone expansion card. For more inputs an optional larger enclosure is available. Optional accessory cards like 24 Vdc input control, relay contact outputs & flash light control are available. Fire Detection System interface Status contact closure outputs (potential free): 230 Vac 48 Vdc ALARM ERROR Panel disabled Contact closure inputs (potential free): Reset Buzzer Lamp test Pause Alarm (incl. led driver output) Microphone (incl. led driver output) Start/reset Alarm (incl. led driver output) ALL ZONES (incl. led driver output) 4x Group/message ABCD (incl. led driver output) The FDS interface can also be used to create a custom Evacuation Panel. Make sure to change the Panel type setting (dipswitch 1-3) to FP or EP depending on the required priority and functionality. NOTE: a switch on the internal pcb of the FDS module allows to reset a running evacuation started by the Fire Alarm system FP/EP/FDS features: Group/message ABCD buttons/inputs: can be programmed to select a combination of outputs, or to select pre-recorded messages (for example a pre-alert/coded or commercial message). When a group of outputs is programmed for 1 of these buttons (contact closure inputs for the FDS interface), this combination is used for all panels of the same type in the system (example: if button A for the Fire Panel is routed, the A button on ALL Fire Panels is using the same routing table, while button A on an Evacuation Panel can have a different routing table or can be used for message selection). When a button is used to select a message, this can be done for each type of panel in the system independently (example: button B on all Evacuation Panels selects message 4, while button B on all Fire Panels selects message 3 and input B on the FDS interface select its routing table). It also features to select 2 messages to be played at the same time (when these messages are played, the routing will be according to the programmed Alarm/Alert routing table for each of the zone buttons in the system). 17

18 11. Emergency panels Enable/Disable ABCD buttons: this feature allows enabling or disabling the use of these 4 buttons for each used panel in the system independently. Note: If for example button B is disabled, this button cannot be used anymore to enter the Panel Enable code which requires a combination of 3 buttons! So when disabling a button, make sure to set the right code for the Panel Enable code. If more buttons need to be disabled, the Panel enable/disable function cannot be used! See also chapter on settings and connections of the FP, EP and FDS interface Panel enabled/disabled (FP/EP): During normal system operation, all emergency panel(s) are disabled (yellow led Panel Disabled is illuminated). To enable the emergency panel one has to enter a combination of keys, using the ABCD buttons, within 5 seconds. When the panel is enabled the yellow indicator will turn off. The FDS interface does not require the enable/disable function to start operating (the Panel disable settings are set to OFF internally). The key combination must consist of 3 buttons. When the Enable/disable ABCD buttons function needs to be used, one can only use this function for 1 button in combination with the Panel enable/disable function. If more buttons need to be disabled, the Panel enable/disable function cannot be used! 11.5 FP/EP/FDS settings and connections: Note: To connect the unit to the system, to change settings or to install expansion cards, the unit needs to be opened.

21 11. Emergency panels Please note that: If more panels are connected (of the same type), use the ID (RS485 address) setting to set individual priority for microphone announcements. Priority handling of alarm messages is only determined by the panel type. Although a Fire Panel has the highest priority in the system, to give an emergency panel a higher priority, change its panel type to Fire Panel (dipswitch 1) and set its RS485 address to higher priority (1= highest, 32 = lowest). Up to 32 emergency panels, spread on both panel busses, can be connected to a single ESC unit. NOTE: when an emergency panel is connected to an ESC slave unit these can only announce into zones of the ESC it is connected to and into lower Slave units. Priority handling of slave connected panels is equal as if connected to an ESC master unit. Emergency announcements activated from an emergency panel connected to a Master unit always have priority over announcements from emergency panels connected to a Slave unit ; a microphone announcement from any panel type connected to a slave ESC unit has lower priority and will be stopped when an alarm signal is activated from any panel type connected to a master ESC unit! 11.6 Entero FP/EP zone expansion module Card to expand a Fire or Evacuation panel with 12 zone buttons. The FP/EP housing allows expansion of 1 module. When more of these zone expansion modules are needed, use the optional (19 ) housing for the EP to expand up to 4 of these zone expansion modules. When more buttons are needed, an additional (19 ) housing can be used to expand up to 6 of these zone expansion modules. Each button can be programmed to route the emergency signal to 1 or a group of outputs, using the computer software. A red led indicator shows the status of each of the 12 buttons: when the button is pressed the LED illuminates. When on another panel in the system a button with the same ID is pressed, this particular LED will flash on all other panels indicating this buttons is already selected (an emergency is probably already activated if so the ALARM indicator will also be illuminated on all other panels). For the FDS interface, a separate version of this module (without button front panel) is available. On the PCB of this module a header is located to drive external LEDs and another header is located to use contact closure inputs for zone selection (instead of the buttons used in a FP/EP). For 24 Vdc control of the 12 inputs and relay contact outputs per buttons/contact input, optional plug in cards are available. Entero FP/EP zone expansion module Text card: the text card behind the front foil can be removed and replaced with a custom text card. 21

Emergency panels Example of an expanded Evacuation panel with 48 buttons: 11.7 Entero FDS zone expansion card The 12 input zone expansion card for the FDS interface is the same as the FP/EP zone expansion module except that the button front panel is not included. Control of the 12 inputs is done by using the contact closure inputs (change dipswitch 14 on the main board to select between push or hold contacts for these inputs). LED outputs (12) are available to connect to external LED indicators (5 V, 20 ma max). See also Entero FP/EP zone expansion module for more details, connections and settings Emergency panel accessory cards: Entero FP/EP/FDS 24 Vdc input card: Plug in card with twelve 24 Vdc inputs to connect to the Fire Detection System (used instead of the contact closure inputs).

Each relay can be programmed individually: when any emergency signal (Alarm, Alert, Microphone or External Input) routed to a zone, a relay contact can be linked to this zone and will be activated at the same time. This contact closure output can be used to trigger flash lights or other external devices. NOTE: The lines between these output contacts and the external connected Fire devices are not monitored. This function does not fulfill the EN54-16 requirements as mentioned in chapter 7.8. NOTE: This card needs to be mounted on a free position (intended for a FP/EP zone expansion module or FDS zone expansion card) in the FDS interface or Evacuation panel!

Make sure to use a proper wire thickness which can handle the required currents, avoiding high losses on the cable Cable requirements Make sure ALL cabling (going out of the system rack) is at least E30 fire retardant cabling: refer to local standards for different requirements on fire resistance for cabling. Use 110 ohm shielded CAT5e or CAT6 cabling to connect emergency panels to the ESC units and to link ESC units to each other. Emergency panel connection cabling pin out: Make sure to connect the shield of the cable to the 19 rack (earth connection)!

(only the first and last unit require 120 ohm termination, see also chapter 7.)

29 12. Hardware system configuration 12.3 Line monitoring & End of Line dummy load: Line monitoring: The system requires a minimum load of 30 W (sum of A & B line) for each output to ensure correct line monitoring (maximum load is 800 W). Line loads below 30 W may not be found during calibration of outputs. The line deviation can be set at 10 W, 25 W or 50 W before a fault is triggered. In low impedance mode the maximum output current is 8 A (= 512 Wrms at 8 ohm). The line deviation in low impedance mode is fixed at 25% before a fault is triggered. Line monitoring is performed using a pilot tone of 1 khz and 20 khz. During calibration of the system the line loads will be checked at both frequencies. When the system is operating it only monitors the lines using the 20 khz pilot tone: during every monitoring run each loudspeaker line is checked multiple times - each measured value will be compared with the stored load value. Only when a deviation is found at 20 khz, the system will activate the 1 khz pilot tone measurement, which is a very quick and almost inaudible measurement: when at 1 khz a deviation is also found the system will generate an error - when no deviation is found at 1 khz, the measurement at 20 khz will be re-calibrated and the new found line load will be stored; no error is generated. The earlier found deviation at 20 khz is probably caused by a temperature deviation of the speaker lines which triggered the line deviation setting; as monitoring at 1 khz is more reliable, ignoring this initial 20 khz fault and re-calibration of the load at 20 khz avoids faulty error warnings. The 1 khz measurement can also be turned off for each output, as for some applications (for example hotel rooms) the 1 khz measurement is not recommended. The 20 khz pilot tone can be changed to 21 khz or 22 khz when needed. This may be useful when for example a loudspeakers produces an audible harmonic frequency of 10 khz (half of the pilot tone frequency), while it may not produce an audible harmonic frequency at a higher set pilot tone frequency. End of Line dummy load: Due to low line loads (below 30 W), or higher loudspeaker impedances at high frequencies, the ESC may not recognize the connected load. To correct this, End of Line (EOL) dummy loads can be used (only for 50/100 V lines, not for low impedance loads), which should be mounted at the last loudspeaker on the line. The EOL dummy load provides 2 loads: about 8W at 1kHz and about 23W at 22kHz. The EOL dummy load also features temperature compensation which helps to stabilize the loudspeaker line load. The loudspeaker line load can in/decrease when exposed to large temperature deviations in or outside a building (for example: when loudspeaker cabling is installed just below the roof of a building which is directly exposed to heat from the sun or cold from snow, the line load will vary due to temperature changes). See appendix C for more information about the End of Line dummy load Entero ESC 4x4 zone expansion card card configuration options: Each zone output features A and B loudspeaker connections, increasing safety and reliability in a single alarm zone. If one of the speaker lines fails, this line will be disconnected while the other line stays operating: this results in a maximum SPL loss of 3 db. NOTE: make sure to wire the speaker lines properly and that the loudspeakers on these lines are spread equally throughout the room (50% on line A and 50% on line B). Instead of using a single amplifier channel for every zone, a single amplifier channel can also be connected to power 2, 3 or 4 zones. All loudspeakers lines are still monitored independently and if one line fails it will be disconnected while the other loudspeaker lines keep operating. The Aux line output can be linked to any of the 4 outputs on the same card. During evacuation, or when running on battery power, the AUX signal will be muted. The AUX signal has its own processing and therefore can also be used as bi-amplified output for any of the 4 outputs on the same card. See examples of above options in appendix A. 29

30 12. Hardware system configuration 12.5 Backup amplifier: The 4 amplifier connections on the main unit and the 4 amplifier connections on the optional 4x4 zone expansion card have the facility to connect a backup amplifier (1 for each 4 amplifiers). If needed a single spare amplifier channel can also be used as a backup for 8 amplifier channels (main unit incl. 1 zone exp. Card) or 12 amplifier channels (main unit incl. 2 zone exp. Cards). Using less backup amplifiers requires specific wiring of the backup amplifier output. The ESC system automatically detects the number of connected backup amplifiers and will route the internal audio signals. Make sure the backup amp wiring is done in the right way: if there is a missing parallel connection the ESC will recognize less backup amplifiers, see examples below: 1 backup amp for 8 zones: connect the backup amp audio output nr. 1 to the backup amp line input and connect its loudspeaker output in parallel to backup amp input nr. 1 AND nr backup amp for 12 zones: connect the backup amp audio output nr. 1 to the backup amp line input and connect its loudspeaker output in parallel to backup amp input nr.1, nr. 2 and nr.3. 2 backup amps for 12 zones: for example - connect the backup amp audio output nr. 1 to the first backup amp line input and connect its loudspeaker output to the backup amp input nr. 1. Connect the backup amp audio output nr. 2 to the second backup amp line input and connect its loudspeaker output in parallel to the backup amp input nr. 2 and nr. 3. The use of one or two backup amplifiers is only possible within a single ESC unit. The output power of the backup amplifier should be equal to the amplifier with the highest output power connected to the same ESC unit. Besides previous the backup amplifier output level (50 V, 100 V or 100 V using a transformer) should match the output level of the amplifiers connected to the different zone outputs: all amplifier channels connected to these zone outputs should have the same type of output level (a 50 V amplifier channel, or 100 V amplifier channel using a transformer cannot be backed up by a 100 V backup amplifier channel; this will give errors in the system!). Also when low impedance line loads (8 ohm at 50 V) are used on a particular zone card: make sure all other outputs of this card are also low impedance lines (8 ohm at 50 V) and that a 50 V backup amplifier is used. Same a low impedance load of 16 ohm (min.) at 100 V: make sure all zones on this card operate at 16 ohm (min.) 100 V and that a 100 V the backup amplifier channel is used. See examples of above configurations in appendix B. 30

31 12. Hardware system configuration 12.6 Message storage cards: The ESC unit includes 2 message storage cards (SD-cards), used to store emergency messages, pre-announcements (for example a chime for the emergency microphone) test tones. They can also be used to store other messages like, alert messages, coded messages for employees and commercial announcements. For evacuation purposes; the 2 emergency messages (Alarm 1 and Alarm 2) can be played at the same time routed to different outputs. Routing of these messages is done using the System menu or by using the Entero ESC installer software. The emergency panels also contain A/B/C/D buttons used (if programmed) for group of zones; these (1 or more) can also be used to select messages (instead of a group of zones) which will be routed according the programmed Emergency message routing matrix. For every type of emergency panel (FP, EP or FDS), different messages can be linked to these buttons (Button A on a Fire Panel can be linked to a different message compared to button A on an Evacuation Panel). Message storage: To store messages on the SD cards, one has to take into account that both cards contain fixed messages which shall not be removed and default messages which must be available, but can be replaced by another message. Besides this, both cards must contain the same messages, all stored in the same order! Track SD card 1: SD card 2: number: 0 16 khz* 16 khz* 1 Default Alarm 1 Message Default Alarm 1 Message 2 Default Alarm 2 Message Default Alarm 2 Message 3 Default Pre-announcement Fire panel Default Pre-announcement Fire panel 4 Default Pre-announcement Evacuation panel 5 Default Pre-announcement FDS interface 6 Default Pre-announcement Ext. audio input Default Pre-announcement Evacuation panel Default Pre-announcement FDS interface Default Pre-announcement Ext. audio input 7 Default Test tone message Default Test tone message When these fixed and default messages are removed, errors will occur in the system as these are used for internal monitoring of the system and other purposes. *Track 0 is used for internal measurement fixed message DO NOT REMOVE! Above 7 default messages should always be available on both cards; these can be replaced with other messages! Up to 250 messages can be stored on each card (incl. default messages). All files should be stored in MP3 format: 44 khz/16 Bit mono - make sure that the recorded level of the MP3 files is at 0 db. The maximum number of tracks may be lower as this depends on the stored file sizes and the storage capacity of the SD-card. When adding messages to the SD cards make sure these are dragged and dropped 1 by 1 according the order as shown in previous table, otherwise the message order on the card will be mixed up. NEVER copy a complete folder with messages to the SD card at once! The ESC unit will use the names of the stored MP3 files: these names will be made visual in the ESC installer software when a message is selected for specific routing. The maximum number of characters for a track name is 8. 31

32 12. Hardware system configuration NOTE: when recording alarm/slowhoop tones make sure to use triangle shaped tone signals having a crest factor of (4.77 db) or higher. Sine wave shaped signal are not allowed: all 48 Vdc currents for power consumption are measured using a triangle shaped emergency tone signal! See below for an example of a triangle based slowhoop signal, starting at around Hz and increasing to Hz in 3.5 seconds: When adding pre-recorded messages, these should have a crest factor of about 12 db. Example of a slowhoop alarm signal and pre-recorded (multiple language) message(s): The alarm tone is played two times followed by a pause of 1 to 2 seconds before the spoken message(s) are played. This will be repeated as long as the emergency is activated. Refer to local standards for duration, multi language and other requirements of pre-recorded messages and alarm tones. Test tone message: The test tone message can be used during setup of the line monitoring of an output of the system. After the zone has been put in test mode (no monitoring takes place) the test tone message can be activated and will be played in this zone. This will help to check if all cabling and loudspeakers are properly wired and connected the customer will not be annoyed by any emergency messages while setting up or maintaining the system. It is allowed to exchange this test-tone to another test tone, as long as there is one available! Make sure to put the specific output(s) back in operating mode by turning of the test mode function in the software, before ending the maintenance/setup of the system. SD card removal: To remove the internal SD cards, make sure to Power off the unit first before removing the small cover plate at the back: 32

33 12. Hardware system configuration The SD cards will pop out after a little press on the card itself. The Alarm SD card is located at the left, the Alert SD card at the right. In a master slave setup of the system, all emergency messages will be played from the master unit and routed to the slave units during an evacuation. If the master unit fails, but system communication (to emergency panels and slave units) is still alive; the first slave unit in the system automatically activates its internal message storage cards to route the same emergency messages to the selected zones. Make sure that the message storage cards in all slave units contain the same messages, stored in the same order, as the messages on the SD cards from the master unit External signal input & Alarm signal output: External signal input: The external signal input can be used to route an emergency signal from an external Voice Alarm system into the ESC unit. When the input contact is activated (closed), the audio signal connected to this input will de routed to all zone outputs. As this line is monitored, add below resistor network to the contact closure and make sure the impedance of the connected source is between ohm (add a parallel resistor to the source to match the impedance if above 1200 ohm). 4.7 kohm External signal Source impedance: ohm Error switch 4.7 kohm It is possible to select a pre-announcement for the External signal input: make sure to take the length of this pre-announcement into account before an external system routes its messages to this input. This External signal could also be used for other applications like a school bel: by using an external timer one can trigger the pre-announcement (bel tone), which will be routed to ALL outputs. Make sure to set the duration (of the contact closure output) of the external timer long enough to complete playback of the internal message. Alarm signal output: The Alarm signal output will provide the Alarm or Microphone message during an emergency situation. A potential free contact closure output (NO) will be activated. This can be used to route the emergency signal to external PA/VA systems Error input & Alarm/Error output contacts: Add below resistor network to ALL error input contact to ensure a proper monitoring of the line: 4.7 kohm Error switch 4.7 kohm Mains fuse input: used to indicate 230 Vac mains failure. Connect to the Entero EPC emergency power controller and Entero ESA power amplifiers 230 Vac error output contact and/or to the error contact of 230 Vac circuit breakers, (optionally) used in the system (for mains power circuits). The ESC unit will indicate a general error when this input is activated. For more info see also Entero ESA power amplifier manual. 33

34 12. Hardware system configuration External error input: connect to the error output contact of an external Voice Alarm system, Redundancy modules or other components in the VACIE. The ESC unit will generate a general error when this input is activated. EPC error input: connect to the error output contact (48 Vdc in & out contact in parallel) of the Entero EPC emergency power controller. The ESC unit will generate a general error. For more info see also Entero EPC emergency power controller manual. GPO output contact (NO): this potential free output contact is activated when there is a 230 Vac failure, but no emergency takes place: this can be used to trigger the standby inputs of the ESA amplifiers to reduce current consumption (Energy save mode). As soon as an emergency message is activated, this output is released again and the amplifier returns in operating mode. During monitoring of the amplifier and connected speaker lines, the amplifier will return to operating mode shortly. NOTE: Make sure that all amplifier channels, from the amplifiers which are controlled by the GPO contact of an ESC, are connected to this same ESC. No connection of amplifiers shall be made to another ESC. Each ESC will trigger its GPO independantly! See also Entero ESA power amplifier manual for more information. System Fault (NO): this potential free output contact is activated during system failures due by MCU & data storage devices of the system. An internal jumper can be set to change this output to a normally closed contact (NO is default). Error 1 contact output (NO): this potential free general error output contact is activated as long as there is an error in the system. Error 2 contact output (NO): this potential free general error output contact is activated as long as there is an error in the system, also when the Entero ESC is de-energized. PSU failure contact output (NO): this potential free output contact is activated when a PSU failure (230 Vac) is found in the system Vdc battery backup input: 48 Vdc input to connect to the emergency power controller (EPC). When the 230 Vac mains power fails, the system automatically switches to the 48 Vdc input. When the system is running on 48 Vdc the source inputs will be muted, reducing current draw of the batteries. WARNING: It is possible to not mute the audio when operating from 48 Vdc, but this will reduce the battery capacity quickly! Increase the battery capacity accordingly and check local regulations if this is allowed. Use the Entero ESC installer software to set this feature. The ESC system includes a feature to trigger the standby input of the ESA amplifiers, reducing idle current consumption and with that reducing the total capacity of the connected batteries. See also GPO output contact function. The EPC unit provides a maximum current of 150 A at 48 Vdc, divided over 6 outputs of 40 A maximum (used to connect to the ESA amplifiers) and 3 outputs of 5 A (used to connect ESC units or other devices in the system). Make sure to calculate the maximum consumption of all connected devices when running at full power: this should not exceed 150 A in total. See Appendix F for examples of battery capacity calculations. The maximum battery capacity of a single EPC is 225 Ah: connect 4 batteries of 12 V/225 Ah in series using the right cabling set. See EPC manual for more details. 34

35 13. User control and system setup Storage of system design and settings: The system design and all settings are stored on a removable memory chip. In case a unit fails; remove the memory chip and put it in a new ESC unit. Make sure the hardware configuration is exactly the same as the faulty unit and that all external connections are connected in the same way. When the new unit is powered up the system will operate as before. Because of internal component tolerances a new calibration may be required. See Appendix J for the location of the memory chip. 13. User control and system setup Scroll Up / Down Jump to 'SYSTEM MENU' & Jump to 'higher' Menu level Jump/Next item on line & Future functions 13.1 User control OK = Confirm or Toggle selection User control of the ESC unit is limited; no changes to the system setting can be made. The menu items system overview, buzzer/led test, 'acknowledge error' and reset error can only be accessed. A password is required to get access to the installation menu items. For more information about control of the ESC unit and control of the emergency panels, refer to the Entero voice alarm - user guide System setup To change the settings of the system one has to enter a password to get access to the installation menu of the system.

42 Appendix B: Backup amplifier configuration options Option 2: 1 backup amplifier channel for 8 or 12 alarm zones Within the same ESC unit, a single backup amplifier channels can also be used as a backup for 8 or 12 zones This option requires specific wiring of the backup amplifier output to the right backup amplifier inputs on the 4x4 zone cards. When connected in the right way the ESC unit will autimatically detect the number of connected backup amplfiers during a calibration run. It is not possible to link a backup amplifier channel from one ESC unit to another. When 2 backup amplifier channels are used for all 12 zones: the 1 st backup amplifier must be used to backup zone 1 8 (connect the backup amp output to backup amp in 1 & 2 of the ESC) and the 2 nd backup amplifier must be used to backup zone 9 12 (connect the backup amp output to backup amp input 3 of the ESC). 42

43 Appendix C: End of Line dummy load Appendix C: End of Line dummy load The End of Line dummy load adds a load of about about 8 W at 1 khz and about 23 W at 22kHz to a 50/100 V loudspeaker line. To avoid loudspeaker line errors due to temperature deviation (which affect the resistance of copper) the EOL dummy load compensates temperature deviation to a certain extend. When for example the loudspeaker line load increases, the EOL load decreases its value. Below graph shows the EOL value at 0, 25 and 50 degrees Celcius: Connection: Red wire Black wire positive (+) connection negative (-) connection 43

44 Appendix D: Loudspeaker lines at 50 V/100 V and cable loss Appendix D: Loudspeaker lines at 50 V/100 V and cable loss Connecting 100 V loudspeakers on lines with different voltages: Connecting a 100 V loudspeaker on a 50 V amplifier output will not cause any problems; this does however result in a loss of sound pressure level. The use of 100 V loudspeakers on amplifier outputs with higher voltages (>100 V) needs to be avoided as this might damage the loudspeaker. Below chart indicates the difference in sound pressure level (in db) when a loudspeaker is connected to different amplifier output levels: Voltage rating of loudspeaker: Amplifier output: 50 V 70 V 100 V 50 V 0 db -3 db -6 db 70 V n.a. 0 db -3 db 100 V n.a. n.a. 0 db Conversion table AWG to mm2: AWG mm Cable loss (stranded copper wire): Cable resistance R= ( *L)/A R = resistance of single wire (in ohms) = resistivity of material in ohms per meter, copper: 1.712*10-8 L = length of single wire in meters A = cross section area of wire in m2 Cable loss (V) = I * (2*R) I = current on wire R = cable resistance (1 wire) Example: 100 V/100 W loudspeaker connected at the end of 100 m/2.5 mm2 cable R = (1.712*10-8 * 100)/(2.5*1 +6 ) > R = ohm Cable loss (V) = (100 W/100 V) * (2 * ) = V Cable loss (db) = 20 LOG (Vout/Vin) = 20 LOG (( )/100) = db 44

46 Appendix F: Emergency power supply battery capacity Appendix F: Emergency power supply battery capacity Refer to local standards for backup power standby time (Tidle) and max. power time (Tmax)! Entero EPC emergency power controller: Continuous output current: 150 A (at 48 Vdc) max. Battery capacity: 225 Ah max. As long as the Entero EPC is powered from 230 Vac the DC outputs can deliver up to 12 A; when the current draw is above 12 A battery, power will be consumed! This only happens when for example an amplifier is disconnected from 230 Vac and needs to deliver output power, while operating from 48 Vdc and current draw exceeds 12 A. Power consumption (A): * NOTE: current consumption is measured using a slow whoop signal based on a triangle wave signal (4.77 db crest factor). ** NOTE: current consumption measured using a pre-recorded message (12 db crest factor). Emergency signals: Below show examples of slow whoop and pre-recorded message signals, used to indicate the calculation of the required battery capacity.

49 Appendix H: Manufacturing a VACIE / Rack building Appendix H: Manufacturing a VACIE / Rack building VACIE: The VACIE (Voice Alarm Control and Indicating Equipment) of the Entero Voice Alarm system complies with EN54-16 when manufactured using a dedicated range of 19 racks, meeting Class 3k5 of EN :1995 as amended by EN :1995/A2:1997 and which meet a minimum IP 30 rating according to EN 60529:1991 as amended by EN 60529:1991/A1:2000. To maintain validity of the EN54-16 Declaration of Conformity; every new system must be manufactured using this same series of 19 racks; mounting of any other products into this 19 rack besides the Entero Voice Alarm components & accessories (see below) is not allowed; wiring of all components must be performed as specified by Bose. EN54-16 certified components: Entero ESC emergency system controller* Entero fire panel* Entero ESA 8125/8250 power amplifier* Entero evacuation panel* Entero TraPack Entero fire detection system interface* Entero EPC emergency power controller* Batteries (brands listed in EPC manual) Entero redundancy module * Including accessories Installation of VACIE: The VACIE should be placed in a climate controlled technical room with an ambient temperature of 21 C with a maximum humidity of 93%. The VACIE should be placed on a solid floor; use of 19 rack wheels is not allowed. Ensure appropriate distance between inlet and outlet duct VACIE TECHNICAL ROOM: Ambient temperature: 21ºC Humidity: < 93% Rack building: 19 rack build to order: The 19 rack will be built to order; the supplier will manufacture the rack, meeting the EN54-16 requirements (optional fan/thermostat, product carriers, battery tray, etc. will be supplied separately). The 19 rack will be delivered with a plexi glass front door. Different locks & keys will be supplied for the front door (cylinder lock EK333) and rear/side panels (cylinder lock 1242E), to meet the different access levels. When mounting the front door, rear-/side panels, make sure to connect all earth cables to the rack chassis. 49

50 Appendix H: Manufacturing a VACIE / Rack building Rack ventilation: Forced air flow is used to cool down the VACIE, maintaining an internal temperature of around 21 C. Below pictures show the installation and location of fans & thermostat, blind panels and the order of component to be mounted, ensuring optimal airflow. The fan(s) needs to be connected to 1 of the 5 A connections of the Entero EPC emergency power controller; when AC mains is disconnected, the fan(s) still operate from battery power. The air flow of the fan is indicated with an arrow on its housing; make sure to mount the fan in the right direction. 48Vdc Fan FRONT ESC Thermostat 21ºC EP REAR ESC ESA ESA ESA TraPack EPC Batteries Batteries SIDE VIEW 19 rack with plexi glass door Fan & thermostat: Fan: Rubsamen & Herr LV250-48Vdc filter: GV250 Thermostat: Stego KTS011 (NO) HU rack: one 48 Vdc fan & thermostat 42 HU rack: two 48 Vdc fans & thermostat

51 Appendix H: Manufacturing a VACIE / Rack building Blind panel requirements: ESC: add a 1HU blind panel above and below unit ESA: 2 amps can be put on top of each other, add a 1HU blind panel above and below unit(s) EPC: add a 1HU blind panel above and below unit TraPack: 1 unit can be mounted below a single ESC, ESA or EPC unit NOTE: do not use ventilated blind panels! Component carrier rails: Carrier rails are available to mount components; a set of 2 carrier rails supports 1 or 2 components. Batteries: Depending on the battery capacity needed, four batteries (W x H x D max.: 440 x 220 x 170 mm) can be mounted at the bottom of the system rack using thread ends, nuts and fixing brackets. If the physical dimensions of the batteries are too large, mount 2 batteries (W x H x D max.: 505 x 220 x 240 mm) at the bottom of the rack and use the battery tray (see picture below), thread ends, nuts and fixing brackets to mount the other 2 batteries (W x H x D max.: 505 x 220 x 240 mm). The four 12 Vdc batteries should be connected in series, parallel connection of batteries is not allowed. Make sure enough space is kept free above the batteries to fit cabling & fuse (optional) and for servicing. The batteries, EPC and the components powered by these batteries & EPC should be mounted in the same 19 rack. If multiple 19 racks are needed for more space; the 19 racks shall be placed side by side and fixed to each other (as if it is one large 19" rack), to ensure that cables (for AC and DC power), connecting components from the first rack to components in the other racks, stay inside these 19 racks. If racks are not located next to each other (e.g. in a de-central system), it is not allowed to make any 48 Vdc connections (for backup power) between these racks: each rack requires its own Entero EPC emergency power controller & batteries and AC mains supply! NOTE: when the EPC is turned ON for the first time, make sure both 230 Vac and the 48 Vdc batteries are connected; if only the batteries are connected the EPC will not start up! When both the AC mains supply and the batteries are present, one can hear a loud 'click' (large relay gets activated) inside the EPC when turned ON. Cable entry: A cable entry is located at the rear-bottom of the 19 rack, which includes several breakout holes (3x M62, 4x M32, 4x M16) to fit cable glands (not included). To meet the IP30 rating: do not leave any of the holes open; close all openings which are not used and fill up open space in cable glands! 51

52 Appendix H: Manufacturing a VACIE / Rack building 230 Vac mains & Mains filter: Mount the AC mains filter(s) at the bottom of the 19 rack, as close to the mains cable entry at the rear of the 19 rack. Make sure the body of the AC filter is properly mounted to an unpainted part of the metal of the bottom of the 19 rack or tightly mounted to the copper screws for best Earth connection. Wire the AC mains cable directly to the mains filter, see picture below. Depending on the AC power consumption of the VACIE more AC mains filter may be required. Wire and distribute the AC mains power accordingly. Check local standards for electrical installation requirements! Mains filter types: 16A: Epcos B84112GB116 36A: Epcos B84112GG136 Connect the output of the AC mains filter to the surge protectors first (if used), before the wiring is split to the different circuit breakers: *See paragraph ESC error inputs below for more information Surge protection (Class II) is used to protect the VACIE for very quick high voltage surges like lightning strokes. The use of these depends on local electrical installation requirements. To prevent that all VACIE components will switch to the emergency power supply, in case of a single 230 Vac failure in or to a single component, a circuit breaker can be used for each individual component. This will also save battery capacity as not all components but only one 52

Below list shows the type of circuit breaker needed for each Entero VA system component: In addition to these circuit breakers one can add an auxiliary error contact unit to each of these. The error contact is closed when the circuit breaker is triggered: this information can be used to route to the ESC AC Mains error input. For more information see chapter NOTE: Entero ESA amplifiers are foreseen with an AC mains error contact closure output, so use of the external auxiliary error contacts is not required. Do not turn ON (circuit breakers for) all amplifiers at the same time, this can result in a to high inrush current for the AC mains supply. Turn ON each amplifier (& circuit breaker) one by one! Component preparation: Before components are mounted into the 19 rack make sure all required accessories, expansion cards are mounted into the different components and that all jumpers (e.g. RS-485 termination) are set. Set the Entero ESA amplifier gain at +6dB (turn potentiometer at the rear of all inputs fully clockwise) and make sure the dipswitches for mono/bridge mode selection are set. Wiring: Check connection of the earth wires of the side panels and front/rear door of the 19 rack: make sure these are connected to meet EMC requirements. Shield of all shielded cabling must be connected to the chassis of the 19 rack! Separate the installation of different types of cables/wires (loudspeaker / audio / error contact / data) as much as possible. Use large vertical and smaller horizontal cables ducts for wiring separation: Power RS485 + RS485 - Sys.

56 Appendix I: Connecting a fire detection system directly to an Entero fire/evacuation panel Appendix I: Connecting a fire detection system directly to an Entero fire/evacuation panel The Entero fire detection system interface is used for zoned evacuation. If only automatic evacuation of ALL control is needed, one can connect the fire detection system to an emergency panel directly. For this connection between the fire detection system and emergency panel, 2 relay contact closures (NO) are required; one to select the All Zones input, which needs to be triggered first to select the zones, and one to select Start Evacuation, which needs to be triggered secondly (after the All Zones input has been triggered) to start the evacuation. Switch to select "all zones" Switch to start the alarm message 56

57 Appendix I: Connecting a fire detection system directly to an Entero fire/evacuation panel See chapter 11 for more information on how to connect other input contacts, error outputs contacts and more. NOTE: take into account that the fire alarm system directly controls an emergency panel and that this automatic evacuation can only be stopped on this same emergency panel! Instead of using the ALL zones input one can also use the Group A/B/C/D inputs to select a (group of) zone(s). Four contact closure outputs to trigger the A/B/C/D inputs and a single contact closure for the Start Evacuation input are required: Button A/B/C/D inputs Switch to start the alarm message 57
