4 1 General about planning the system 1.1 When is a fire alarm needed? Fire detection and alarm systems are installed mainly to protect human life. The early warning of smoke detectors alerts people to evacuate the building in an orderly manner. In hotels and similar, alarm bells or sirens provide sufficient noise to wake up people. Fire detection and alarm systems are also installed on premises where stocks, machinery or other property are to be protected. A fire detection system gives an early indication, making it possible to start and finalize the rescue work quickly thus allowing the normal activities to continue soon. A fire detection system often brings lower insurance rates. If getting a building permit requires installation of a fire alarm system, a sufficient degree of coverage must be provided. The extent of such coverage is specified in national and international regulations. 1.2 Planning an automatic fire alarm system The automatic fire detection system should be planned and installed in a way that guarantees that a starting fire in the area to be surveyed is detected as early as possible and a fire alarm indicating the location is activated. Faults that might jeopardize the reliability of the fire detection system should also be reported. If needed (for example for quotation purposes) a preliminary plan should be made as well as an installation plan for the detection system. Preliminary plan The preliminary plan can be made by the electric engineer, the contractor or the manufacturer's representative. Installation plan The installation plan is made by the manufacturer's representative or an authorized fire detection and alarm planning engineer. The planning includes: Selection of detector types and manual call points and specifying their location taking into consideration coverage, environment, building construction etc. Selection of types of alarm devices (bells, sirens, flash light beacons etc.) and specifying their location to ensure that everybody in the building is alerted. Selecting cable types and planning the routing of the cables within the building. Specifying any control functions needed for fire protection e.g. signals to extinguishing systems, ventilation systems, fire doors or shutters etc. Taking into consideration any additional requirements from the fire authorities. It may be a requirement by the local fire authorities that the plan is inspected and approved by a third party before the installation commences GB1 4/

6 2 General description of an FX system 2.1 Standalone FX-2 (-4, -6, -8) fire detection system Main features The modular design of the FX-2 (-4, -6, -8) control panel offers a competitive solution for small sized, as well as for medium sized projects. The address capacity of the detection circuits also offers a flexibility with regards to cabling, thus saving costs of installation work. A wide range of intelligent detectors provides solutions for all applications. In addition conventional detectors can be connected to interface modules or CLC boards in the panel, making an upgrade of a former conventional system flexible. The Intellia series of I/O-modules are both economic and space-saving in installation and provide monitoring and control functions. With the extensive configuration software all addresses and many control functions of the panel can be adopted to the requirements of the installation site. The serial communication port(s) makes it possible to connect a standard printer and additional alarm display panels.

14 4 FX-2 (-4, -6, -8) construction The FX panel is a modular construction, facilitating easy expansion and selection of needed modules. The panel consists of a back plate in sheet metal, specially designed racks that holds the electronic boards and a cover in plastic. Two different cabinet types are available for housing the control panel and in addition a cabinet with blank cover is available for housing of batteries or auxiliary equipment. The electronics are distributed on boards as follows: - FX-UI the User Interface board contains an LCD display, LEDs and buttons - FX-MC the Main Controller contains the main processor and basic mandatory inputs and outputs - FX-PS the Power Supply unit is responsible for standby battery charging, voltage regulation and power supply to the panel and external circuitry. - FX-ALC the Loop Controller takes care of power distribution to the detection circuits (loops), communication with the addressable devices connected to the loops and monitoring and control of the loop cabling. - FX-IOC the Input/Output Controller provides clean contact signal inputs, clean contact signal outputs and alarm device outputs. - FX-SA the Serial Adapter contains the circuitry for galvanically isolated serial data communication. Signalling between the boards goes through a motherboard between the racks. 4.1 FX cabinet The FX cabinet has space for the following - 1 x UI - 1 x MC (+SA) - 1 x PS - 5 x ALC or CLC(max. 4) or IOC (max. 4) - 2 x Battery 12V / 17Ah MC PS 4.2 FXL cabinet The FXL cabinet has space for the following - 1 x UI - 1 x MC (+SA) - 1 x PS - 4 x ALC or CLC - 4 x IOC MC PS GB1 14/

16 5 FX-ALC addressable detection circuits, addresses, zones 5.1 Addressable detection circuits and addresses The cables that connect the detectors and the I/O-modules to the panel are called detection circuits (or loops in some ESMI documentation). The detection circuits are identified by a two-digit number and are by default: for an FX panel with two detection circuits (one ALC Loop Controller) for an FX panel with four detection circuits (two ALC Loop Controllers) for an FX panel with six detection circuits (three ALC Loop Controllers) for an FX panel with eight detection circuits (four ALC Loop Controllers) With the configuration software the detection circuit identifications can be changed to any consecutive range of numbers with a maximum value of 99. The detectors and the I/O-modules are individually assigned a number (address) during installation and can therefore be identified by the panel, using a proprietary communication protocol. The address setting for detectors is simply done by inserting an address card in the base of the detector. Prepared (address set) cards are available as a series with addresses Each base also comes with a blank card that can easily be set to a certain address at the installation site. The address setting for IO-modules is done with binary coded address switches. Within the system a detector (or I/O-module) is identified by the detection circuit and the setting of the address. This identification is expressed in the FX (and MESA) displays as dc.add, where dc is the detection circuit and add is the address setting, e.g Max. 126 addresses (detectors and IO-modules) in free order. System capacity System type Detection circuits Max det. addresses FX 2 (one ALC) FX 4 (two ALC) FX 6 (three ALC) 6 512* FX 8 (four ALC) 8 512* System type Detection circuits Addresses MESA(16 FX panels) * The maximum number of detectors and manual call points has to be kept as 512 for compliance with the EN54 standard. For other purposes the full address range of 126 addresses per loop can be used. NOTE! In a MESA system the MESA user panels and the FX control panels must be configured before they are connected to each other. A stand-alone FX system can be commissioned and used without configuration, however, the following has to be considered: Every time the system is started, the presence of all addresses has to be manually verified. The zone assignments of the addresses are according to a default scheme GB1 16/

17 GB1 17/

18 5.2 FX detection zones Detectors of a fire detection system are usually grouped to detection zones. In conventional systems the detection circuit coincides with a detection zone, but in addressable systems like the FX, the detectors are grouped by the software. The zones are identified by a four-digit number in the range and they have to be consecutive within an FX panel. In a standalone FX system the addresses are by default assigned to zones according the following scheme, but this assignment can easily be changed with the configuration software. When configured, any detector within the FX panel, even in different detection circuits, can be assigned to any zone. All addresses have to be assigned to some zone. Default assignment of addresses into detection zone s Detection circuits (Loops) Addresses 1 st Loop Controlle r 2 nd Loop Controller 3 rd Loop Controller 4 th Loop Controller L 1 L 2 L 3 L 4 L 5 L 6 L 7 L FX control zones The concept of control zones in an FX panel is a way of grouping the various inputs of the panel to facilitate activation of outputs. The control zones are defined separately from the detection zones, although they are the same as default. Control zone inputs are not limited to the detectors and other addressable devices on the loop, also monitoring inputs in the panel can be members of control zones. Control zone outputs can just as well be both addressable outputs on the loop as relay outputs in the panel. Control zones goes hand in hand with events. There are two kinds of events, input events and output events. Input events are the type of signals that the control logic reacts on, e.g. when a detector gives a fire signal we say that the input event is a fire event. Output events are events activated (triggered) by the logic. Certain input events have corresponding output events, e.g. a fire input event corresponds to an alarm device output event. To say it with one sentence: When an input event for a specified control zone occurs, the corresponding output events for the same control zone are activated. There are 250 specific control zones in an FX panel and one general control zone. In this document these are identified with the numerical values and the word General, respectively. For input events, two control zones can be assigned, in this document referred to as In-Zone-1 and In-Zone-2. For output events, up to all 250 specific control zones or the General zone can be assigned, in this document referred to as Out-Zones. An input event is signalled to both In-Zone-1 and In-Z one-2 immediately when the event occurs, except if the device is set up for delayed alarm. If the input device is set up for delayed alarm the event is signalled to In-Zone- 1 immediately, but to In-Zone-2 after the delay GB1 18/

19 An output device, that is configured to belong to the Gener al control zone, responds to its corresponding input event from any input devices, regardless of the control zone assignments of that input device. An output device, that is configured to belong to any one, or combination of, of the specific control zones (1 250), responds to its corresponding input event, only from input devices with a matching control zone assignment. C ontrol zone inputs and events Following is a list of devices that can create input events Device Input event Fire alarm Prewarning Fault warning Detectors Maintenance warning Disablement Comment When the user makes an address disablement, or the address is disabled due to day mode (see 7.1 ).

21 5.4 FX-ALC addressable detection circuit structure The detection circuit cabling can be arranged in a variety of lay-outs, being flexible for all applications. However, following has to be considered when selecting a cable lay-out. The cable resistance between the panel and any detector may not exceed 60 Ω. If a large number of sounders, powered from the detection circuit, are used, the maximum resistance may be further restricted to ensure sufficient voltage to all devices (see chapter 5.6). The cable capacitance may not exceed 360 nf. Not more than one zone (max. 32 detectors and/or manual call points) may drop out of operation in case of a fault in the cable. There are limitations on number of devices between short-circuit isolators (see chapter 5.5). Closed detection circuit (highly recommended) A closed detection circuit gives the highest safety, because the panel can still communicate with all addresses even if the cable is cut. To minimise the effect of a short-circuit, isolators are available which reduces the number of dropped-out addresses to the addresses between the isolators that are closest to the short-circuit. The rule of max 60 Ω between panel and any detector has to be considered even if the cable is cut in either end of the detection circuit. The cable capacitance in this layout is normally not an issue of concern. Closed detection circuit with branches (recommended with reservations) Branches are allowed if the length of the branch is kept short (< 100 m) and if the number of addresses that may drop out in case of a cable failure is less than 32. Again the rule of cabl e resistance has to be considered in any case of cable cut. The capacitance may be an issue if there are several branches. Check with the cable manufacturer and calculate the total capacita nce. Open-end detection circuit (not generally recommended) This is least efficient utilization of the cable, since only 32 addresses can be use d on the circuit. With that restriction in mind, it can still provide the longest distance between the panel and the farthest address. Closed detection circuit Open-end detection circuit <60 Ω <60 Ω Closed detection circuit + addressable branches Short circuit isolator <60 Ω <60 Ω <60 Ω GB1 21/

22 5.5 Number of devices between short circuit isolators Using short circuit isolators and returning the detection circuit to the panel, the full capacity of the detection circuit can be used. Short circuit isolators have to be installed at the boundary of each zone to comply with the requirement that not more than one zone falls out of operation in the case of a single cable fault. It may be necessary to use additional short circuit isolators if the current consumption of the devices between two isolators otherwise exceeds the following specification. During start-up of the detection circuit (before the isolators have connected all segments) current is fed from the already powered-up side of the isolator to the other side through a circuit that limits the current to 50 ma. If the voltage on the others side reaches 14 V, the isolator by-passes the current limiter and connects full supply to the other side. If there is a short circuit or if the load on the other side is too high, the isolator will cut off the current and try again after approx. 5 seconds. All devices have a surge current that can be significantly higher than the standby current. The sum of the surge current for all devices between the isolators has to be less than 45 ma to assure a proper startup. Following table shows the load factors of the addressable devices. The corresponds to the 45 ma limit. total load factor can not exceed 20, which Load factor x Pcs = Load factor EDI-10 Ion Smoke Detector 1 EDI-20 Optical Smoke Detector 1 EDI-30 Photo-Thermal Detector 1 EDI-50/xx Heat Detector 1 EDI-60 Carbon Monoxide Detector APOBeam Detector APO Flame Detector 20 EPP-10 Manual Call Point 1 EPP-20 Manual Call Point 1 EMI-301 Single Output Module 3 EMI-301/S Sounder control module 3 EMI-310 Switch Monitor module 3 EMI-310+ Switch Monitor+ module 3 EMI-310/CZ Conventional Zone Monitor Module 3 EMI-311 Input/Output Module 4 EMI-311/ V Relay Output Module 4 EMI-333 Three channel Input/Output module 12?

23 5.6 Number of devices in an addressable detection circuit It is necessary to make careful calculations of load on, and resistan ce of, the detection ci rcuit especially if addressable sounders are installed on the detection circuit. The resistance from the panel to any device has to be less than 60 Ω and this is to be the case even if there s one cut anywhere in the detection circuit. It may be necessary to further decrease the resistance and thus the voltage drop, by u sing thicker cable, if the alarm load is high. Maximum peak current The current consumption of the components in the detection ci rcuit indicated in dat a sheets and other documentation is the mean value and is good for battery backup ca lculation. However, the planning of the detection circuits should take into consideration also the following: A short circuit isolated by two isolators = 2 x 50 ma pulses every 5 seconds = 100 ma peaks Additional pulsating current drawn by the devices during communic ation = 20 ma The current of the detection circuit is limited to 600 ma by the panel. The total load (including above mentioned 120 ma) of all devices connected to the detection circuit in normal condition as well as in alarm condition can not exceed 600 ma. Voltage drop calculation The more symmetrically (with respect to the centre of the cable) the load is distributed, the better with respect to voltage drop. On the contrary, the more the load is concentrated close to either end of the cable (no matter which, because the system has to operate from either end, even if the other end is cut) the worst it is with respect to voltage drop. The v oltage drop can be calculated with the formula where Itot * Rtot * a Itot = total current (in alarm condition and including above mentioned 120 ma) Rtot = total resistance a = correcting factor for load distribution With a perfectly symmetrical distribution of t he load, the voltage drop is only half (b = 0,5) com pared with all load being at ei ther end (b = 1). A generally safe v alue to use is b = 0,85 that corresponds to an evenly distributed load over half of the cable (0, 75) + a safety margin of 0,1. The highest minimum voltage for the addressable devic es is 17V, and since the loop provide a m inimum voltage of 27 V, we can use 10 V as the maximum allowed voltage drop in the loop cabling. Subsequently the formula for calculating max allowed detection circuit cable resistance is Rmax = 10 V / (Itot * a) NOTE! * In the following table the alarm current for the detectors are included for your information only and should not be used for the voltage drop calculation. The alarm current for the detectors is increased only by the LED s and the FX panel restricts the number of lit LED s to 5. Therefore the alarm current for the detectors are added at the end of the table as 5 times 3 ma.

25 6 Conventional detection circuits 6.1 Conventional detection circuit controllers (CLC) The FX panels can also be equipped with Conventional Loop Controllers (CLC). The CLC board takes one loop controller place in the panel. Thus the following combinations are possible: ALC s CLC s Comment 1 No addressable loops, 1 to 16 conventional lines 2 No addressable loops, 17 to 32 conventional lines 0 3 No addressable loops, 33 to 48 conventional lines 4 No addressable loops, 49 to 64 conventional lines 0 2 addressable loops (each 126 addresses) 0 conventional lines 1 2 addressable loops (each 126 addresses) 1 to 16 conventional lines addressable loops (each 126 addresses) 17 to 32 conventional lines 3 2 addressable loops (each 126 addresses) 33 to 48 conventional lines 0 4 addressable loops (each 126 addresses) 0 conventional lines addressable loops (each 126 addresses) 1 to 16 conventional lines 2 4 addressable loops (each 126 addresses) 17 to 32 conventional lines 0 6 addressable loops (each 126 addresses) 0 conventional lines addressable loops (each 126 addresses) 1 to 16 conventional lines addressable loops (each 126 addresses) 0 conventional lines Note! The total number of detectors and manual call points, connected to one FX panel, may not exceed 512, to fulfill the EN54 standard. The FX panel handles internally the who le CLC board as one addressable loop and each conventional line as an address of that loop. Each conventional line can therefore be configured and used just as the conventional zone modu le connected to an addressable detection circuit. It also means that the conventional lines are handled by the user in the same way as the conventional zone modules, e.g. for disablement/re-enablement. Ea ch line is by default in its own detection zone. 6.2 Compatible conventional detectors and manual call points Compatibility of detectors with the CL C conventional line is determined by the following factors: - Supply voltage range - Current consumption in standby condition - Vo ltage across the detector in alarm condition - Series resistance (either in the detector or in the base) - End-Of-Line resistor The voltage supplied by the CLC to the c onventional line is 21Vdc to 24Vdc. The maximum allowable voltage drop in the cable is 21V minus the lowest operating voltage of the connected devices. If the line goes through an Exi barrier, the maximum allowed cable resistance and current consumption is less than for a normal line. The following table shows the required series resistor for a number of detector voltages (in alarm condition), the two allowed EOL types and whether or not a Exi barrier is connected to the loop.

The value of this resi stor can be either 4k7 or 2k94, depending on the type of detectors connected to the line and the alarm series resi stor the detector or its base has. Max 32 detectors and manual call points together. The number may further be reduced by the current consumption of the devices. See table in chapter 6.2 for required series resistors and EOL resistors. 6.4 Configurable options For different applications the operation of the conventional line can be modified through the configuration tool WinFX. Following items can be configured: Detection zone identification The conventional line can be a member of any detection zone of the panel Control zone 1 and control zone 2 Control zones are used to group detectors, manual call points, signal inputs and (see chapter 5.3) also conventional lines for common control output functions Functional type In addition to Manual call point line and Detection line items selectable for addressable monitor modules are selectable EOL resistor Whether the line is Normally Open (NO) or Normally Closed (NC) 4k7 (default) or 2k9 NO (default) usually used for manual call point lines and detection lines. NC may sometimes be useful for signal inputs Whether the line is monitored for A break in the line is by default indicated as a fault. In special cases it may be breaks or not useful not to have break monitoring on Whether a short circuit should be indicated as fault or as alarm Whether the line is used in an intrinsically safe area (Exi-area) A short circuit is by default indicated as a fault. To interface with old style conventional loops, it may be necessary to indicate a short circuit as an alarm condition The barrier that is used at the entry to the Exi area is seen as an increased resistance in the line. This setting compensates. Alarm mode Special alarm modifiers, like co-incidence, delayed alarm output, prealarm only or local alarm only Whether the line should have a double-knock feature or not Filter value for avoiding disturbances Whether the line should be disabled by Day Mode or not Whether the line should be disabled by a zone disablement or not Double-knock means that the panel resets the line for a few seconds and if there is an alarm signal still after this reset the panel indicates the alarm. Used to avoid false alarms. The default setting of 2 means that 2 verifying measurements are taken from the line before an alarm condition is raised To avoid false alarm it may be necessary to disable parts of the fire alarm system during day mode Zone disablements are typically made to avoid false alarms and it is usual to only disable smoke detectors.

28 7 Special features to avoid nuisance alarms It is a well k nown fact that fire detection and alarm systems, while operating fully according to standards and specificat ions, may initiate alarms in situations that are not really fire situations. These alarms are called nuisance alarms and are mostly the result of activities in the building that create physical phenomena that resembles those that the fire detection system is designed to react upon. These activities includes, as examples, - construction work (may create smoke or fine particle dust that looks like smoke) - welding (creates smoke) - cooking (creates steam that may look like smoke, or heat from an open owen) - tobacco smoking - operating heavy machinery (may create electrical fields well beyond what a system is required to withstand) The selection of detector type and the lo cation of the detector should always be carefully considered as the first step to avoid nuisance alarms. If the selection of detector type and the loca tion of the detector do not give a satisfactory result, the FX system provides features to minimize the risk of nuisance alar ms while still providing the safety against real fire incidents as required by the standards. Since the usage of these measures against nuisance alarms may delay the signalling of real fire incidents, it is mandatory to carefully assess the need of these measures, and agree upon the usage of them with local fire authorities, insurance companies and the owner of the building. 7.1 Day mode It is a common practice to prevent nuisance alarms by disabling detectors in areas where the normal activities in the building create phenomena resembling a fire. This is often done by ma king the disablement at the panel or by a special device, giving a disablement command to the panel. The device can for example be a timer switch that the worker turns to a number of hours and a specified detection zone is disabled for the time set. Although this functionality is available in the FX system, it also introduces an automation of this action and an alternative to complete disablement. Day mode, as the term implies, is an operational mode of the system, used during day time, where certain settings reduces the risk of nuisance alarm. The settings that are selectable during day mode are: - disablement of selected detectors and addressable IO modules (or addresses in general) - decreased sensitivity of selected intelligent detectors The settings are selectable individually for each address in the system. Day mode is activa ted and deactivated, for example, by a contact in the central clock system, ensuring that the workers do not forget to turn it on and off. 7.2 Delayed alarm Delayed alarm is anoth er way of preventing nuisance alarms, acknowledged by the standard, and widely adopted in some European countries. It is, and should be, used only when trained personnel is at the site. The function involves an initial delay of alarm router and/or alarm devices and/or other control output functions. During this delay (typically 60 seconds) the person, trained and responsible, reacts on the alarm and gives a signal to the system that he is aware of the alarm and investigating it. This signal activates an additional delay time (typically 5 minutes) during which the person investigates the situation and resets the system if the alarm was a nuisance alarm. If the situation is a real fire incident, the delay can be terminated immediately from the nearest manual call point. If a timeout of either the initial delay or the additional delay occurs, all delayed control functions are activated. The Delayed alarm function is enabled with a signal input, either together with the day mode input or separately. The initial delay time and the additional delay time are set in 10 seconds increments and are limited by the standard to a maximum of 5 minutes and 10 minutes, the total delay time being furthe r restricted to a maximum of 10 minutes. Delayed alarm mode is selected individually for each address (normally only fo r smoke detectors). Delay is terminated by a non- delayed alarm signal (normally heat detector or manual call point). Delay termination can also be selected to occur when a se cond (delayed alarm) detector gives a fire signal. 7.3 Delayed signal inputs A third way to avoid nuisance alarms is to use delayed signal inputs. The time can be set in 10 seconds increments up to 60 seconds and is typically set to 20 or 30 seconds. The function requires that the signal from the detector remains above alarm level for the selected time before an alarm is issued by the panel. If the signal Kommentti: Feasible with Intellia detectors? GB1 28/

29 goes below the alarm level, the timer is stopped. This effectively filters out transients in the detectors or in the communication between the panel and the detectors. Because of the internal operation of the detectors and the way the panel schedules measurement requests (polling) from the detectors, this function works best for loops with less than 50 detectors, while Attenuation of signal input changes works best for loops with more than 50 detectors. 7.4 Attenuation of signal input changes Attenuation of signal i nput changes is a way to smooth rapid changes in the signals from the detectors. It effectively reduces the difference betw een the last received signals and previous calculated signal value to the fraction difference/(1+ n) where n is the selected attenuation factor in the range Because of the internal operation of the detectors and the way the panel schedules measurement requests (polling) from the detectors, this function works best fo r loops with more than 50 detectors, while Delayed signal inputs works best for loops with less than 50 detectors.
