1. Introduction Prescient II Gas Extinguishant Control Panel Installation and Operation The Prescient II Gas Extinguishant Control Panel is a standalone panel intended for use with gas extinguishing systems. The panel monitors three zones or areas for fire conditions and gives an appropriate audible and visual indication. Zones 1 & 2 are used for coincident detection and can be used to automatically release the extinguishing gas. The third zone is an auxiliary zone & only provides an alarm indication. The panel also provides a facility for initiating the release of extinguishing gas manually. 2. General Description The Panel is housed in a metal enclosure with a Manual Release facility mounted on the front. The display board provides the following functions: 1) Visual Indication of panel status via LEDs. 2) Buttons for User Control.

Functional Description Note: Please refer to Section 10 for PCB layout and Section 12 for Connection Diagram. 3.1 Detection Zones (ZONE 1, ZONE 2 & AUX.ZONE) Three detection zone circuits are provided. They are monitored for Open Circuit Fault, Short Circuit Fault and Alarm (Fire). A maximum of 20 active detectors are allowed on each zone (the actual number is dependent on the type of detector used, see section 6). Any number of passive devices may be used e.g. Manual Call Points. Zones 1 and 2 are normally used together to produce First and Second Stage fire alarms, resulting in automatic extinguishant discharge ( Double Knock Zones). Zone 3 is an auxiliary detection zone and is not used to automatically discharge the extinguishant. The Display Board has Fire and Fault LEDs for each of the zones. The Display Board also provides User Controls for disabling the monitoring of individual zones. 3.2 Manual Release Zone (MREL ZONE) The fourth detection zone is used as a Manual Release zone. It is monitored for Open Circuit Fault, Short Circuit Fault and Alarm. It is classed as a Second Stage alarm in both automatic and manual modes, and initiates the release of extinguishant when activated. This zone should only have manually operated devices connected to it e.g. Manual Call Points. The Display Board has Fire and Fault LEDs for the Manual Release Zone. The Manual Release zone cannot be disabled by the user. 3.3 Alarm Circuits (ALARM 1 & ALARM 2) Two fully monitored alarm circuits are provided. They are monitored for Open Circuit and Short Circuit faults. They are rated at 1 Amp (fused), 28 Volts DC each. An amber LED on the main Control Board is illuminated for any fault conditions an the Alarm Circuits. Note: The circuits are reversepolarity monitored. The PCB terminals are marked for the active polarity. Ensure that all connected devices are polarised. 3.4 Actuator Circuits (ACT 1 & ACT 2) Two fully monitored actuator circuits are provided. They are monitored for Open Circuit and Short Circuit faults. They are rated at 1 Amp (fused), 28 Volts DC each. An amber LED on the Display Board is illuminated for any fault conditions on the Actuator Circuits. Note: The circuits are reversepolarity monitored. The PCB terminals are marked for the active polarity. Ensure that all connected devices are polarised. 3.5 Repeater Outputs (REPEATER 1, 2, AZ, MZ, FLT & EV) Each repeater output consists of an Open Collector transistor driver capable of sinking up to 100mA. One output is provided for each of the detection zones to indicate zone alarm. In addition, one output is provided to indicate a panel fault and one output is provided to indicate the operation of manual/remote evacuate. 3.6 Auxiliary 28 VDC Supply (AUX SUP + & ) The panel provides an auxiliary d.c. power supply output for connection to ancillary equipment. The output is rated at 1 Amp (fused), 28 Volts D.C. 3.7 Status Lamp Unit The panel provides a 28 Volt D.C. output (28VS) rated at 0.5 Amp (fused) to provide power to a Remote Status Lamp Unit. Page 4 of 27

Outputs for AUTO (AS), MANUAL (MS) and DISCHARGED (DIS) are provided via relays on the panel. These outputs are normally open and switch to 0V. Each output is rated at 250mA. Outputs for TIMER HELD (T/H) and EMERGENCY ABORT (A) are provided via Open Collector transistor drivers, rated at 100mA each. Note: Total loading of all five outputs should not exceed 500mA. 3.8 Remote Inputs 3.8.1 Remote Evacuate (EVAC) The panel can accept a 0V input on the Remote Evacuate terminal. This will cause the alarm circuits to operate continuously until the input is removed. 3.8.2 Silence Alarms (RSIL) The panel can accept a 0V input on the Remote Silence Alarms terminal. This will cause the alarm circuits to deactivate if they are activated for a fire condition. If the alarm circuits are activated by an Evacuate signal and no fire signals are present then this input will have no effect. 3.8.3 System Reset (RST) The panel can accept a 0V input on the Remote System Reset terminal. This will reset the panel indications to normal and remove the power supply to the zones to clear any detectors in a fire condition. This input is only accepted if the alarm circuits have already been silenced for a fire condition. 3.8.4 LockOff Switch (LOFF) The Lockoff input consists of two terminals; one input terminal and one 0V terminal. This input monitors for short circuits with a 680R endofline monitoring resistor. A short circuit fault is indicated by an amber Lock Off Fault LED on the internal control board. The input is normally closed. An open circuit condition disconnects the 680R resistor resulting in an activation of the input. In the active state the panel is placed in manual mode and the green Manual LED on the display board pulses. Operation of the Auto/Manual button on the display board has no affect while the LockOff input is active. 3.8.5 Low Pressure Fault (LP) The Low Pressure Fault input consists of two terminals; one input terminal and one 0V terminal. This is a fully monitored input with a 3K9 endofline monitoring resistor. An open or short circuit fault is indicated by an amber Low Pressure Fault LED on the internal control board. The input is normally open and requires a 680R resistor across the circuit for the active state. An active condition illuminates the amber Low Pressure Fault LED on the display board. 3.8.6 Pressure Switch (PS) The Pressure Switch input consists of two terminals; one input terminal and one 0V terminal. This is a fully monitored input with a 3K9 endofline monitoring resistor. An open or short circuit fault will be indicated by an amber Pressure Switch Fault LED on the display board. The input is normally open and requires a 680R resistor across the circuit for the active state. An active condition indicates Gas Discharged, illuminating the red Gas Discharged LED, red First Stage LED and red Second Stage LED on the display. 3.8.7 Remote Timer Hold (T/H) The Remote Timer Hold input consists of two terminals; one input terminal and one 0V terminal. This is a fully monitored input with a 3K9 endofline monitoring resistor. An open or short circuit fault is indicated by a Remote Hold Fault LED on the display board. The input is normally open and requires a 680R resistor across the circuit for the active state. An active condition illuminates the amber Timer Held LED on the display. It also resets and holds the extinguishant release timer if running. NOTE: A maximum of 3 Remote Timer Hold switches may be connected. If more than 3 switches are operated simultaneously then a short circuit fault will be detected and the Timer Hold function will be cancelled. Use only nonlatching switches which return to open contacts when the switch is released. 3.8.8 Emergency Abort Input (AI) The Emergency Abort Input consists of two terminals; one input terminal and one 0V terminal. This is a fully monitored input with a 3K9 endofline monitoring resistor. An open or short circuit fault is indicated by an Abort Input Fault LED on the internal control board. The input is normally open and requires a 680R resistor across the circuit for the active Page 5 of 27

state. An active condition illuminates the Emergency Abort LED on the display and prevents the release of extinguishant until the panel is reset. Page 6 of 27

3.9 Clean Relay Contacts 3.9.1 First Stage (FIRST STAGE) The First Stage Relay is a double pole double throw relay and is energised whenever a First Stage Fire condition is activated. Two sets of contacts are available. The first set has Normally Open and Normally Closed changeover contacts; the second set only has Normally Closed contacts. 3.9.2 Second Stage (SECOND STAGE) The Second Stage Relay is a double pole double throw relay and is energised whenever a Second Stage Fire condition is activated. Two sets of contacts are available. The first set has Normally Open and Normally Closed changeover contacts; the second set only has Normally Closed contacts. 3.9.3 Auxiliary Reset (RESET) The Auxiliary Reset Relay is a single pole single throw relay and is energised briefly when the panel is in System Reset mode. The relay is energised for 7.5 seconds. This is to allow ancillary equipment such as Beam Detectors to be reset. Only two terminals are provided, which are normally closed. 3.9.4 Auxiliary Fire (FIRE 1 & FIRE 2) The Auxiliary fire Relay is a double pole double throw relay and is energised for any Zone Fire condition. It is deenergised only on System Reset. Two sets of three terminals are provided, giving open and closed changeover contacts. 3.9.5 Auxiliary Fault (FAULT) The Auxiliary Fault Relay is a single pole double throw relay. It is a failsafe relay and is therefore normally energised. It is deenergised for any fault condition and remains deenergised until all faults are cleared. Three terminals are provided; giving one set of open and closed changeover contacts. 3.9.6 System Discharged (DISCHARGE) The System Discharged Relay is a single pole single throw relay and is energised when the Pressure Switch input is activated or if the NO PRESSURE SWITCH function is selected and the Actuator circuits are operated. It is deenergised on System Reset. Only two terminals are provided, which are normally open. 3.10 Internal Standby Batteries Two terminals are provided to allow connection of one set of internal standby batteries. The Charger Circuit is monitored to ensure correct charging of any attached batteries. Incorrect charging or disconnection results in a fault indication, illuminating the amber Power Fault LED and Battery Charger Fault LED on the internal control board. 3.11 Function Enable/Disable Switches Three sets of DIL switches and two jumper links are available on the internal control board to allow the panel to be configured for additional sitespecific functions: 3.11.1 Function Select Switch This consists of two sets of 8way DIL switches to provide the following options: Page 7 of 27

3.11.1.1 One Man Test Mode 3.11.1.2 See Manual Enables onemantest during commissioning i.e. automatic reset of zones when activated. This switch has no assigned function. 3.11.1.3 Zone 1 Double Knock Zone 1 produces a second stage alarm in auto mode i.e. the extinguishant release timer is started if Zone 1 registers a fire condition in auto mode. 3.11.1.4 Zone 2 Double Knock Zone 2 produces a second stage alarm in auto mode i.e. the extinguishant release timer is started if Zone 2 registers a fire condition in auto mode. 3.11.1.5 Zones Intrinsically Safe Allows the use of Zener barriers (or galvanic isolators) for intrinsically safe operation of zones 1 to 4. 3.11.1.6 No Pressure Switch Gives a Gas Discharged indication when the actuator circuits are operated, for installations where the Pressure Switch input is not used. If the Pressure Switch input is not used and this switch is not enabled then operation of the actuator circuits will not produce a Gas Discharged indication on the panel. 3.11.1.7 Actuator Short Circuit Monitoring Disable 3.11.1.8 2 x Delay Disables the actuator short circuit indication. This is intended for use in installations where the C1565 monitoring and suppression board has not been fitted to solenoids on the actuator circuits. Doubles the delay length set by the discharge timer delay configuration switches (see 3.11.2). 3.11.1.9 Alarm1 First Stage, Alarm2 Second Stage Alarm Circuit 1 operates for a 1 st stage alarm condition and a 2 nd stage alarm condition. Alarm Circuit 2 operates only for a 2 nd stage alarm condition. 3.11.1.10 Alarms First Stage Pulsed/Continuous Alarm Circuits 1 and 2 pulse for a 1 st stage alarm condition if this switch is OFF. Alarm Circuits 1 and 2 are continuous for a 1 st stage alarm condition if this switch is ON. 3.11.1.11 Alarms Second Stage Pulsed/Continuous Alarm Circuits 1 and 2 pulse for a 2 nd stage alarm condition if this switch is OFF. Alarm Circuits 1 and 2 are continuous for a 2 nd stage alarm condition if this switch is ON. 3.11.1.12 Manual Release gives instant discharge Disables the discharge timer for manual release, i.e. if a Manual Release device is activated the actuator circuits are operated immediately instead of after the timer has ended. 3.11.1.13 Inhibit Silence Alarms during Gas Imminent Prevents the alarms from being silenced during the last 15 seconds of the discharge timer. 3.11.1.14 Buzzer Rapid Pulse at end of delay Causes the internal Buzzer to pulse rapidly during the last 15 seconds of the discharge timer. 3.11.1.15 Evacuate operates Aux. Fire Relay Manual Evacuate or Remote Evacuate rings the bells and also operates the auxiliary fire relay. 3.11.1.16 Latching Faults Page 8 of 27

3.11.2 Discharge Timer Set Switch All fault conditions produce a general fault indication even after the fault has been cleared, until manually reset by operating Silence Buzzer and then Reset System. This is an 8way DIL switch to allow setting of the timer. The switches can be used in any combination and are additive. This gives a maximum delay of 4 minutes 15 seconds (This can be doubled up to 8 minutes 30 seconds see 3.11.1.8) 3.11.3 Actuator 1 Minute Cut Off Option This is a single jumper link. When present, it causes the actuator circuits to be switched off automatically after 1 minute of activation, for actuators that do not require a continuous supply. 3.11.4 Link For Earth Fault Monitoring 3.12 Fault LEDs This is a single jumper link. When present, it allows the panel to monitor for earth faults on the cables coming into the panel. If this link is REMOVED, it physically isolates the internal control board from mains earth, thus disabling the earth fault monitoring facility. Ten Amber LEDs are mounted on the control board to indicate the following faults: 1. POWER FAULT This LED illuminates for any power supply related fault. 2. DISPLAY FAULT This LED illuminates if the display is disconnected. 3. EARTH FAULT This LED illuminates for any cabletoearth fault. 4. ALARM FAULT This LED illuminates for any alarm circuit fault. 5. LOCK OFF FAULT This LED illuminates for a cable fault on the Lock Off input. 6. ABORT INPUT FAULT This LED illuminates for a cable fault on the Emergency Abort input. 7. LOW PRESSURE FAULT This LED illuminates for a cable fault on the LOW PRESSURE FAULT input. 8. MAINS FAULT This LED illuminates if the a.c. mains input voltage is lost. 9. INTERNAL FAULT This LED illuminates if the a.c. mains input voltage is lost or if there is a short circuit across the Thermistor input. 10.BATTERY CHARGER FAULT This LED illuminates if the batteries cannot be charged for any reason, e.g. faulty batteries or disconnected batteries. One Green LED is provided to indicate that the voltage from the power supply output is acceptable. The ten amber fault LEDs on the internal control board are normally OFF and illuminate continuously for the relevant fault. The General Fault LED on the Display board pulses for any of the above faults. 3.13 Internal Buzzer The internal buzzer provides an audible indication to compliment the visual indications provided via the LEDs on the panel. The buzzer has various modes as follows: 1. Fault Indication Pulse, 1 second On, 3 seconds OFF The buzzer can be silenced for most fault indications. Page 9 of 27

2. Alarm Indication Continuous The buzzer cannot be silenced. 3. Alarms Silenced Pulse, ½ second On, ½ second OFF The buzzer cannot be silenced. 4. Buzzer Pulse End Of Delay Pulse, ¼ second On, ¼ second OFF The buzzer cannot be silenced. 5. Button Press Continuous whilst any button is pressed 3.14 Display Board General The Display board is connected to the internal control board via a 50way ribbon cable and polarised ribbon socket. A latching polarised 50way header is provided on the main control board at position J1. Q O P S W R A E F G H D B I J K L C 2 4 3 5 6 8 7 9 1 10 11 12 N M T V U X Y 3.15 Display Board Visual Indications LEDs on the display board provide a visual indication of the panel status, as follows: 3.15.1 (A) Power Supply On This is a green LED that is normally illuminated continuously to indicate that the panel is supplied with power. 3.15.2 (B) General Fault This is an amber LED that is normally OFF. If a fault condition exists for which a separate LED is not provided on the display board then the general fault LED pulses. 3.15.3 (C) Processor Fault This is an amber LED which is normally OFF. It is controlled from two circuits: 1. If the microprocessor fails and is restarted by the watchdog circuit then the microprocessor illuminates the LED until the SYSTEM RESET button is pressed. 2. If the microprocessor fails and cannot be restarted by the watchdog circuit then the watchdog circuit illuminates the LED. This indication cannot be cleared unless the microprocessor restarts. Page 10 of 27

3.15.4 (D) System Disabled This is an amber LED which is normally OFF. If any disablements are present on the panel then this LED pulses until all disablements are cleared. 3.15.5 (E) Zone 1 Fire This consists of two red LEDs that are normally OFF. A fire condition on Zone 1 pulses the LEDs until the Silence Alarms function is activated. The LEDs are then steady until System Reset. 3.15.6 (F) Zone 2 Fire This consists of two red LEDs that are normally OFF. A fire condition on Zone 2 pulses the LEDs until the Silence Alarms function is activated. The LEDs are then steady until System Reset. 3.15.7 (G) Auxiliary Zone Fire This consists of two red LEDs that are normally OFF. A fire condition on the Auxiliary Zone pulses the LEDs until the Silence Alarms function is activated. The LEDs are then steady until System Reset. 3.15.8 (H) Manual Release This consists of two red LEDs that are normally OFF. An active condition on the Manual Release Zone pulses the LEDs until the Silence Alarms function is activated. The LEDs are then steady until System Reset. 3.15.9 (I) Zone 1 Fault This is an amber LED that is normally OFF. The LED pulses if there is a fault present on Zone 1. The LED is steady if Zone 1 is disabled. 3.15.10 (J) Zone 2 Fault This is an amber LED that is normally OFF. The LED pulses if there is a fault present on Zone 2. The LED is steady if Zone 2 is disabled. 3.15.11 (K) Auxiliary Zone Fault This is an amber LED that is normally OFF. The LED pulses if there is a fault present on the Auxiliary Zone. The LED is steady if the Auxiliary Zone is disabled. 3.15.12 (L) Manual Release Fault This is an amber LED that is normally OFF. The LED pulses if there is a fault present on the Manual Release Zone. 3.15.13 (M) First Stage This is a red LED that is normally OFF. If a First Stage alarm occurs the LED is illuminated until System Reset. 3.15.14 (N) Second Stage This is a red LED that is normally OFF. If a Second Stage alarm occurs the LED is illuminated until System Reset. 3.15.15 (O) System Auto This is an amber LED and is illuminated if the panel is set to automatically operate the actuator circuits. 3.15.16 (P) System manual This is a green LED that is illuminated if the actuators can only be operated manually. This LED pulses if the Lock Off input is active. Note: The System Auto and System Manual LEDs are mutually exclusive and one or the other will always be illuminated. 3.15.17 (Q) Gas Discharged This is a red LED that is normally OFF. It is illuminated when the Extinguishant is released. This is usually detected via the Pressure Switch input but may be operated when the actuator circuits are operated if the panel is configured for NO PRESSURE SWITCH (see section 3.11.1.6). The LED will be cleared on System Reset. 3.15.18 (R) Actuator Operated This is a red LED that is normally OFF. It is illuminated when the actuator circuits are activated. The LED will be cleared on System Reset. 3.15.19 (S) Timer Held Page 11 of 27

This is an amber LED that is normally OFF. It pulses when the extinguishant release timer is running and is steady when the timer is held. It switches OFF after the timer has ended or on System Reset. 3.15.20 (T) Low Pressure This is an amber LED that is normally OFF. It is illuminated when the Low Pressure input is active and clears only when the input is cleared. 3.15.21 (U) Pressure Switch Fault This is an amber LED that is normally OFF. It pulses if there is a cable fault on the Pressure Switch input. It remains pulsing until the fault is cleared. 3.15.22 (V) Remote Timer Hold Fault This is an amber LED which is normally OFF. It pulses if there is a cable fault on the Remote Timer Hold input. It remains pulsing until the fault is cleared. 3.15.23 (W) Actuator Fault This is an amber LED which is normally OFF. It pulses if an open circuit or short circuit fault is detected on either of the actuator circuits. It remains pulsing until the fault is cleared. 3.15.24 (X) Emergency Abort Operated This is an amber LED and is normally OFF. It is illuminated if the Emergency Abort input is active. The indication latches until panel reset. The LED pulses if the Abort Input is active in a nonalarm condition. 3.16 Display Board User Controls The Display Board provides user controls via buttons behind the membrane of the display board. All buttons except for TIMER HOLD are disabled until the ACCESS CONTROLS keyswitch is rotated to position 1. Operation of any button will activate the internal buzzer until the button is released. The following functions are available: 3.16.1 (1) Evacuate This button operates the alarm circuits continuously when operated once. It must be operated again to silence the alarm circuits. If it is operated during a fire condition then Silence Alarms must be operated to silence the alarm circuits. The Auxiliary Fire relays are not normally operated by this function but can be selected to operate via a DIL switch on the main control board. 3.16.2 (2) Silence Alarms This button allows the alarm circuits to be silenced during a fire condition. The buzzer changes from a continuous sound to a rapid pulse. A new fire or evacuate condition clears the Alarms Silenced mode, reactivating the alarm circuits and returning the buzzer to continuous. 3.16.3 (3) Reset System This button initiates a System Reset if the panel is currently in Alarms Silenced mode (as described above). During System Reset all outputs and indications are cleared. The devices on the zones are reset (i.e. the zone supply is disconnected for 1 second) and the Auxiliary Reset relay is operated for 7.5 seconds. 3.16.4 (4) Silence Fault This button silences the buzzer during a fault indication but only if that fault is allowed to be silenced. Faults that cannot be silenced are: (i) (ii) (iii) (iv) (v) (vi) 3.16.5 (5) Auto/Manual Processor Fault when controlled by the watchdog circuit. Zone Disabled. Relay Disabled. Actuator Circuit Disabled. One Man Test Mode Active. Display Fault. Page 12 of 27

This button toggles the panel status between Automatic and Manual discharge mode unless the Remote LockOff input is active, in which case the panel remains in Manual mode and the button has no effect. Page 13 of 27

3.16.6 (6) Timer Hold This input is only effective when the discharge timer is running. When pressed the timer is reset to the start value and remains inactive until the button is released, at which point the timer then becomes active again. 3.16.7 (7) Test Display This button illuminates all the LEDs on the panel display and the internal control board except for MAINS FAULT, INTERNAL FAULT and BATT CH FAULT. The buzzer also sounds. The Test Display mode is active until the button is released. 3.16.8 (8) Disable Actuators This button isolates the actuator circuits and prevents them from being operated or monitored for faults. The actuator circuits can be deisolated by operating the button again. 3.16.9 (9) Disable Relay This button isolates all the auxiliary relays and prevents them from being operated. The relays can be deisolated by operating the button again. Note: The Auxiliary Fault relay is still operated. 3.16.10 (10) Disable Zone 1 This button disables fault and fire monitoring on zone 1. Full monitoring can be restored by operating the button again. 3.16.11 (11) Disable Zone 2 This button disables fault and fire monitoring on zone 2. Full monitoring can be restored by operating the button again. 3.16.12 (12) Disable Auxiliary Zone This button disables fault and fire monitoring on the Auxiliary zone. Full monitoring can be restored by operating the button again. Note: All zone disable/enable operations result in the zone power supply being disconnected for a period of 10 seconds. 4.

Alarm/Actuator 1.5mm 350 metres The charger output is designed for charging Valve Regulated Sealed LeadAcid batteries, which are characterised by a reducing charge current when charged from a constant potential source. It will not provide the maximum charging current when the other power supply outputs are fully loaded. The panel requires two 12V batteries connected in series to produce 24V. CONNECTING ONE 12 VOLT BATTERY OR INCORRECT CONNECTION OF THE BATTERIES WILL DAMAGE THE PANEL AND THE BATTERY. WARNING: A fuse protects the internal mains transformer; always replace this with the correct type and rating: T3AH 250V (20mm fuse, 3A, HBC, Antisurge, approved to BS EN 60127 or equivalent.) 5. Standby Battery Requirements 5.1 Battery Capacity Calculation The usual requirement for standby batteries is 24 Hours standby plus 30 Minutes in Alarm. Use the following as a guideline when calculating your requirements. 24 Hours Standby Mains Failed current X Standby Time = Battery Capacity Required in Amps in Hours in AmpHours Mains Failed current is 0.083A plus ancillary equipment e.g. if a Status Indicator draws 0.15A then the total Mains Failed current is 0.233A. Therefore over 24 Hours the Battery requirement is 0.233 X 24 = 5.592 Ah 30 Minutes Alarm Alarm current X Alarm Time = Battery Capacity Required in Amps in Hours in AmpHours Alarm current is 0.200A plus the detector current plus alarm and solenoid current plus ancillary equipment e.g. if one detector is in alarm and draws 30mA, and the alarm load is 1.0A, and the actuator load is 1.0A and a Status Indicator draws 0.15A then the total Alarm current is 2.38A. Therefore over 30 Minutes the Battery requirement is 2.38 X 0.5 = 1.19 Ah Therefore the total Battery requirement is 5.592 + 1.19 = 6.782 Ah Use batteries with a rating of at least 25% more than the capacity required. This is to allow for deterioration of the batteries during use. Please note that the enclosure will only accommodate two 12V batteries up to 7Ah capacity. Larger sized batteries must be housed in a separate enclosure mounted next to the panel. Where batteries are housed in a separate enclosure, the Thermistor should also be positioned in the battery enclosure to ensure correct charge control by the power supply. 5.2 Battery Charging The battery charger voltage is preset during manufacturing and should not require adjustment. The output voltage can be verified by measuring the voltage across the battery terminals on the internal control board with the batteries connected. The battery charger output should be 27.08V +/ 0.05V @ 25 o C (Thermistor value 5K). If the charger voltage requires adjustment, use an insulated trimming tool to adjust the potentiometer VR1 (see PCB layout diagram in section 10 for location). Use a 5K resistor in place of the thermistor when setting the voltage. Care should be taken when adjusting this potentiometer, as it is located between two large heatsinks that may be hot.

7. Panel Installation WARNING: Read this section completely before commencing installation. Prior to commencing installation of the control panel, ensure that adequate precautions are taken to prevent damage to the sensitive electronic components on the control board due to electrostatic discharge. You should discharge any static electricity you may have accumulated by touching a convenient earthed object such as an unpainted copper radiator pipe. You should repeat the process at regular intervals during the installation process, especially if you are required to walk over carpets. The panel must be located in a clean, dry position, which is not subject to shock or vibration and at least 2 metres away from pager systems or any other radio transmitting equipment. The operating temperature range is 0ºC to 40ºC; maximum humidity is 95%. IMPORTANT NOTES ON BATTERIES: DANGER: Batteries are electrically live at all times, take great care never to short circuit the battery terminals. WARNING: Batteries are often heavy; take great care when lifting and transporting batteries. For weights above 24 kilos, lifting aids should be used. DANGER: Do NOT attempt to remove the battery lid or tamper with the internal workings of the battery. Electrolyte is a highly corrosive substance, and presents significant danger to yourself and to anything else it touches. In case of accidental skin or eye contact, flush the affected area with plenty of clean, fresh water and seek immediate medical attention. Valve Regulated Lead Acid (VRLA) batteries are low maintenance, requiring no electrolyte topup or measurement of specific gravity. WARNING: Only clean the battery case with a cloth that has been soaked or dampened with distilled water. Do not use organic solvents (such as petrol, paint thinner, benzene or mineral spirits) or other materials that can substantially weaken the case. Do not use a dry cloth as this will generate static electricity, which in turn may lead to an explosion. WARNING: Avoid operating temperatures outside the range of 15 C/5 F to +50 C/122 F for float/standby applications. The recommended normal operating temperature is 20 C. HIGH TEMPERATURE will reduce battery service life. In extreme cases this can cause Thermal Runaway, resulting in high oxygen/hydrogen gas production and battery swelling. Batteries are irrecoverable from this condition and should be replaced. LOW TEMPERATURE will prolong battery life but reduce output capacity. DANGER: Do not incinerate batteries. If placed in a fire, the batteries may rupture, with the potential to release hazardous gases and electrolyte. VRLA batteries contain substances harmful to the environment. Exhausted batteries must be recycled. Return them to the battery manufacturer or take them to your Council waste disposal site for appropriate disposal. ELECTRICAL SAFETY: The voltfree relay contacts provided within the panel must not be used to directly switch any voltage that exceeds 50VAC or 75VDC. (Please also refer to relay rating data). This equipment requires a 230V AC supply. All installation work should be carried out in accordance with the recommendations of BS5839 Part 1 and the current edition of the IEE regulations by suitably qualified and trained personnel. THIS PANEL MUST BE EARTHED Page 17 of 27

Locate the small plastic bag containing the installation spares as follows: (i) (ii) (iii) (iv) End of Line Resistors (3k9 Ohms) Spare 20mm glass fuse links A set of battery leads (+ve, ve and jumper lead) Electronic End of Line Terminators 3. Disconnect the display ribbon cable from the internal control board by unlatching the ribbon socket and pulling firmly but gently on the ribbon cable connector. 4. Remove the control panel chassis and control board from the enclosure by undoing the screws located on the chassis. Do not remove the control board from the chassis. Place the chassis unit safely to one side. 5. Place the empty enclosure against the wall, mark and fix using the single hole fixing in the upper section of the enclosure back plate. Level the enclosure and complete the fixing operation using the remaining two fixing holes in the lower section of the back plate. 6. Gland the installation wiring into the enclosure using the cable entry holes provided at the top of the enclosure. Leave the plastic protection plugs in any unused holes. 7. When all installation wiring is complete, check all the wiring to ensure that it is free from short circuits, open circuits, earth faults, crossed connections etc. Connect the end of line resistor (or Electronic ELT) across the terminals of the last device in each of the zone wiring runs. The end of line resistors are to be found in the panel terminals, spares are also provided in the small plastic bag supplied with the panel. Check that each Manual Call Point is fitted with an activation resistor (in the range 470 Ohms to 680 Ohms). Note: If any zones, alarm circuits, or solenoid circuits are not being used, then the end of line resistor must be connected across the appropriate terminals in the panel. 8. Connect an end of line resistor across the terminals of the last device in each of the alarm wiring runs. 9. Connect an end of line resistor across the terminals of the last device in each of the solenoid wiring runs. If you are using the C1565 monitoring and suppression board instead of the end of line resistor, then note that only one board can be used on each circuit. 10. Reattach the chassis and control board to the enclosure by refixing the screws located on the chassis. 11. Terminate all field wiring into the relevant terminals on the control panel. Ensure that any unused zones and inputs have end of line resistors fitted in their terminals. 12. Connect 230V AC mains to the mains terminal block provided inside the enclosure, ensuring that the mains supply is isolated at the source. The mains cable must be secured to the enclosure via a Cable Tie. The cable must be protected by a 5A fuse at the source. NOTE 1 MAINS ISOLATION: An appropriate lockable double pole disconnect device shall be provided as part of the building installation. NOTE 2 MAINS CABLES: Use only mains cable compliant to BS6004, BS6500, or equivalent, within the following limits: Cable Diameter Conductor Diameter Minimum Dimensions 4.0mm 1.0mm (0.8mm 2 ) Maximum Dimensions 8.0mm 2.25mm (4.0mm 2 ) DO NOT AT THIS STAGE TURN ON THE MAINS SUPPLY TO THE CONTROL PANEL. 13. Reconnect the display board ribbon cable to the internal control board. Page 18 of 27

7.2 Commissioning Procedure NOTE: In order to avoid accidental operation of the solenoid valves during commissioning it is recommended that the solenoid valves remain disconnected during the commissioning process.
