DESCRIPTION The AFSCP MK2 Panel is a robust and compact unit operating from an external power supply of 12v DC or 24v DC. The Panel comprises of two units which are linked by a pre-wired cable which easily plugs into each unit. One unit is the Controller Unit which mounts in an accessible location for the operator to monitor and control. The other unit is the Interface Unit which terminates to the vehicle’s wiring. The Interface Unit’s wiring looms are pre-terminated with Deutsch connectors for ease of installation. The AFSCP MK2 Panel is fully automatic and has internal battery backup for a minimum time period of 24 hours when the battery charger is showing a full charge. The Panel will detect a fire and activate a latching solenoid or a metron, which will release a fire suppressant to quell the fire. A Jumper Switch inside the Interface Unit must be set as described in the SETTINGS description on Page 14 of this manual. There are four supervised inputs which the Panel monitors:

• Fire Detection.

• Manual Activation.

• Cylinder Pressure.

• High Temperature Probes. There are three outputs:

• A 12volt Dc output which will activate a latching solenoid or fire a metron.

• An Engine Shutdown Relay with common, normally open and normally closed contacts.

• An External Alarm Relay which has common, normally open and normally closed contacts. The Panel’s external alarm feature may be used to interface to optional alarm indicating devices such as buzzers and strobe lights. The Panel uses coded functions to enable Engine Shutdown Override, System Fault Reset, System Reset, System Isolation and System Electrical Test Activation. The Panel exhibits the following features:

• Robust construction

• High quality anodised, milled aluminium enclosures. The lid perimeters have a neoprene o-ring seal to meet IP65 enclosure rating. A stainless-steel mounting bracket provides for ease of installation of the Controller Unit.

• Plug-in termination connectors for ease of installation.

• High intensity system status indicating LED’s

• Internal re-chargeable Lithium Ion battery.

• Internal battery charger with status indicating LED’s to display Charging, Full Charge and battery Fault. The charge termination and automatic recharge feature avoids constant charging to prolong the life of the Li-Ion battery, while keeping the capacity at a healthy level.

• High sound output buzzer.

• System Fault identification, both visual and audible.

• Input voltage reverse polarity protection and transient surge suppression.

• Input voltage EMI Filter.

• Two Switches for selecting functions and controlling operational features of the Panel, as described in the Operation Section of this manual

OPERATION

5

ON: The GREEN “ON” LED is continuously illuminated when the Panel is powered from a 12 or 24volt dc voltage supply. In this “ON” state, the Panel is monitoring the status of all inputs. The Panel’s RED multifunctional SWITCH will now enable the Panel’s “TEST” function and also Enable the Function which has been selected by the BLUE Switch’s “SELECT FUNCTION”. One of the Battery Charger indications will be illuminated as described in the BATTERY CHARGER paragraph on this page. If the Panel is powered ON without the internal backup battery connected, the BATTERY CHARGER’S RED “FAULT” LED will become continuously illuminated. There is no audible indication when this “FAULT” LED is illuminated. The Panel will function normally but without battery backup. When the Panel is powered ON with the internal backup battery connected, the YELLOW “CHARGING” LED will initially become illuminated and remain in this state until the battery is fully charged. The charging LED will then turn off and the GREEN “FULL CHARGE” LED will turn on. NOTE: The internal backup battery won’t “Power Up” the Panel when there is no external power applied to the Panel. Once external power is applied, the battery becomes enabled. The battery also becomes enabled if it is connected after the main external power has been applied to the Panel. MAIN PWR. FAIL: There is no interruption of power to the Panel when there is a loss of main external power. Upon detection of a loss of external input voltage to the Panel, the internal backup battery will continue to power the Panel. The GREEN “ON” LED will turn off upon detection of a loss of input voltage, but after approximately ten seconds delay, it will commence to flash ON once every three seconds. The YELLOW “MAIN PWR. FAIL” LED will also commence to flash in synchronization with the GREEN “ON” LED. There is no audible indication of loss of main power. The internal Backup Battery, when showing a “FULL CHARGE”, will continue to power the Panel for a minimum time period of 24 hours, after which the RED “BACKUP BATT. LOW” LED will become illuminated. BACKUP BATT. LOW: When the Panel detects a low battery voltage, the RED “BACKUP BATT. LOW” LED will become continuously illuminated. Also, the buzzer audible indication will commence to pulse at the same synchronized rate of the flashing “ON” and “MAIN PWR. FAIL” LED’s. The “MUTE” switch will now become functional so that the buzzer may be muted if required. If the Panel is indicating a battery low state, and the “MUTED” LED is also illuminated, the remaining time period before the Panel turns OFF is approximately 24 minutes. If there is a fire-detection during this 24minute remaining time period, there is no guarantee that the Panel will function normally, as the battery voltage will drop quickly. Therefore, the Main Power should be restored as soon as possible when the backup battery is low. BATTERY CHARGER: The battery charger is set to charge the internal Li-Ion battery at a maximum charging current of 830mA. It also continuously monitors the battery temperature and other parameters during the charging cycle. When the Battery Charger is charging the internal Backup Battery, the YELLOW “CHARGING” LED will be continuously illuminated. Upon completion of the charging cycle, the charging LED will turn off and the GREEN “FULL CHARGE” LED will become continuously illuminated. A fully depleted battery will take approximately 3.5 hours to reach a FULL CHARGE. A charge termination and automatic recharge feature avoids constant charging to prolong the life of the Li-Ion battery while keeping the capacity at a healthy level. The “FAULT” LED may turn on during the battery’s charging cycle if a high battery temperature, a high device temperature or a charging timer fault is detected. The “FAULT” will automatically reset when the charging parameters return to normal. The charging cycle will then continue normally until the battery is fully charged.

The AFSCP MK2 Panel has four coded functions:

• ENGINE SHUTDOWN OVERRIDE

• SYSTEM FAULT/ACTIVATION RESET

• SYSTEM ISOLATE

• SYSTEM ELECTRICAL TEST ACTIVATION

The Blue “SELECT FUNCTION” switch may be used to select one of the four functions. A short audible ‘beep’ is heard each time that the switch is pressed. The Red “ENABLE FUNCTION” switch enables the function that has been selected by the Blue switch. The “SELECT FUNCTION” and the “ENABLE FUNCTION” procedure must be carried out within a five second timeframe. A short audible ‘beep’ will be heard when timeout occurs. If timeout occurs, the procedure must be repeated. To clear a selected function, press both the RED and BLUE Switches simultaneously.

The AFSCP MK2 Panel monitors four supervised inputs.

• FIRE ALARM DETECTION

• MANUAL ACTIVATION

• CYLINDER PRESSURE

• HIGH TEMPERATURE DETECTION FIRE ALARM DETECTION: Either Fire-wire or normally open contact Temperature Probes may be used as fire alarm detection devices. A 4.7k Ohm resistor must be used to terminate the ‘end of the line’ of the Fire-wire or the ‘end of the line’ of parallel connected Temperature Probes. The Panel’s” Release Output” may activate either a Latching Solenoid or a Metron. SW4, which is located inside the Interface Unit, must be set to ‘ON’ when using a Latching Solenoid and set to ‘OFF’ when using a Metron. Refer to SETTINGS on Page 14 and FIG 3 on Page 15. The following description refers to Fire-wire as the Fire Detection device and a Latching Solenoid as the device for release of fire suppressant. When the Fire-wire is subjected to a fire, the cable wires will short together and the Panel will detect a closed circuit at the FIRE ALARM INPUT. The panel will latch and continuously illuminate the RED “FIRE ALARM” LED and the buzzer will emit a continuous audible tone. At the same time, the Panel’s Release Output will energise the systems latching Activation Solenoid. The latched solenoid will initiate the release of the fire suppressant to quell the fire. The Solenoid is activated by a relay contact which switches the negative 12V DC voltage terminal of the Solenoid’s coil to the negative voltage supply of the Panel’s activation circuit. A capacitor, which complies with the solenoid’s specification, has the stored voltage and current capacity to latch the Solenoid. The capacitor will discharge when the Solenoid latches, but after approximately three seconds the Panel will de-activate the Release Output and the capacitor will re-charge. At the same time that there has been a Fire Alarm Detection, the Engine Shutdown Delay timing sequence will commence and also the External Alarm Relay will energise. As the fire suppressant discharges, the loss of Cylinder Pressure will be detected at the Panel’s ‘Cylinder Pressure’ Input when the Cylinder Pressure Switch contacts close. The YELLOW “SYS. FAULT” LED will now latch and become continuously illuminated. As the Panel has now detected that there has been a fire detection and that the Cylinder Pressure is low, it will latch and illuminate the RED “SYSTEM DISCHARGED” LED as an indication that the fire suppressant has been discharged.

7

Engine Shutdown will occur when the selected “DELAY” timing period expires. This may be zero, six, twelve, or twenty-four seconds as set by the “DELAY” Jumper Link which is located inside the Controller Unit. The Engine Shutdown Relay will energise when the set timing expires. ENGINE SHUTDOWN cannot be aborted but may be DELAYED by pressing the Panel’s RED switch either momentarily or holding it down as required. The set timing delay until Engine Shutdown occurs, will re-commence upon release of the switch. Approximately three seconds prior to energising the engine shutdown relay, the continuous audible alarm indication will change from a continuous to a rapid intermittent signal to alert the operator that the timer has almost expired. The RED “Delay Engine Shutdown” switch will remain functional during the rapid audible alarm indication . A “ONE SHOT” option, as selected by the ONE SHOT Jumper Link which is located inside the Controller Unit, allows the engine shutdown delay timer to be reset once only. Refer to the “ONE SHOT” SETTING on Page 14 and FIG 1 on Page 15. At the completion of the engine shutdown delay sequence, the panel’s engine shutdown relay will energise and the RED “ENG. SHUTDOWN” LED will illuminate. The audible indication will now change to a post alarm indication which consists of a single one second ‘beep’, which is audible once every twenty seconds. The Panel will automatically reset the Latching Solenoid approximately twenty seconds after activation. MUTE: The post alarm ‘beeps’ may be muted by pressing the Panel’s RED “MUTE” switch. A momentary press will mute the buzzer and illuminate the YELLOW “MUTED” LED. The external alarm relay will also de-energise when the “MUTED” LED is illuminated. Each momentary press of the switch will toggle the “MUTED” LED and the External Alarm on and off. ENGINE SHUTDOWN OVERRIDE: Engine shutdown may be overridden after there has been a system activation as described in the previous paragraphs. To override Engine Shutdown, press the BLUE switch TWO times. A short ‘beep’ will be heard each time the blue switch is pressed. Then enable the function by pressing the RED switch. When the RED switch is pressed, the Red “ENG. SHUTDOWN” LED will turn of and the engine shutdown relay will de-energise. Engine Shutdown may be re-enabled by clearing the function. To do this, press both the RED and BLUE switches simultaneously (CLEAR FUNCTION). NOTE: It is not a requirement, but a recommendation, that the Panel’s audible post alarm should be MUTED whenever selecting one of the Panel’s Coded Functions . Unless MUTED, the post alarm ‘beep’ will be heard whenever the Panel displays “SYS. FAULT” or “SYS. ISOLATED”. The post alarm ‘beep’ may occur while selecting a function and may therefore cause an interruption or distraction to the selection procedure.

8

SYSTEM ACTIVATION RESET: When there has been a System Activation, as described in the “FIRE ALARM DETECTION” description on Page 6 of this manual, the following procedure must be followed to reset the Panel. ALL SUPERVISED INPUTS to the Panel MUST be set to their normal operational state. There cannot be any closed switch contact to the inputs of the Panel. If ENGINE SHUTDOWN HAS BEEN OVERRIDEN, the function MUST BE CLEARED by pressing the RED and BLUE switches simultaneously. THE RED “ENG. SHUTDOWN” LED MUST BE ILLUMINATED BEFORE THE PANEL CAN BE RESET. Press the RED switch to MUTE the Panel, if it has not already been muted. Now the Panel can be reset.

Press the BLUE switch THREE times. A short ‘beep’ will be heard each time the blue switch is pressed. Then enable the function by pressing the RED switch. When the RED switch is pressed, the Panel will reset. Now only the Panel’s Green “ON” LED will be illuminated and also one of the Battery Charger status indications. MANUAL ACTIVATION: SW1, which is located inside the Interface Unit, must be set to the OFF position. Refer to Switch Settings on Page 14 and FIG 2 on Page 15. A manually operated switch with a 4.7k Ohm End of Line Resistor wired across the N/O contacts is used as the Manual Detection device. To manually activate the Panel, press and release the MANUAL ACTIVATION SWITCH. The Panel will detect a closed circuit at the Manual Activation Input and from now on the description will be the same as for FIRE ALARM DETECTION as description on Page 6. CYLINDER PRESSURE DETECTION: The Cylinder Pressure Input monitors a normally open Pressure Switch which provides a closed circuit when the pressure is within the “set pressure operating range” of the switch, and an open circuit when the pressure drops below the “set pressure operating range” of the switch. When the Cylinder Pressure drops below the “set pressure operating range” of the Pressure Switch, the switch contacts will open and the Panel will detect an open circuit at the CYLINDER PRESSURE Input. The Panel will then latch and continuously illuminate the YELLOW “SYS. FAULT” LED and also energise the EXTERNAL ALARM RELAY. The post alarm ‘beep’ and the external alarm device may be muted ON and OFF as required, by pressing the RED switch. HIGH TEMPERATUE DETECTION: SW2, which is located inside the Interface Unit, must be set to the “OFF” position. Refer to Switch Settings on Page 14 and FIG 2 on Page 15. One or more Temperature Probes may be used to monitor critical temperature levels at selected areas of the vehicle. The Temperature Probes must have Normally Open Switch Contacts when the operating temperature is within the set temperature range of the Probes and Closed Switch Contacts when the temperature

9

rises above the set operating temperature range of the probes. Multiple Probes are wired in a parallel configuration and a 4.7k Ohm resistor must be connected across the “end of the line” of the probes. When the ambient temperature level exceeds the set operating temperature range of the probes, the switch contacts will close. The Panel’s High Temperature Detection input will detect the closed circuit and will flash the RED “FIRE ALARM” LED together with synchronised audible buzzer ‘beeps’, once every second. The buzzer ‘beeps’ may be muted ON and OFF as required, by pressing the RED switch. The visual indication will continue and cannot be reset while the high temperature condition persists. The Panel’s flashing FIRE ALARM indication and the audible ‘beeps’ will automatically clear when the temperature drops to within the set operating temperature range of the probes. SYSTEM ISOLATED: The System Isolated feature of the Panel will inhibit System Activation whilst the Panel remains ISOLATED. This will ensure that there will be no ‘accidental’ activation of the Panel when the vehicle is under maintenance. To Isolate the Panel, press the BLUE switch FOUR times. A short ‘beep’ will be heard each time the blue switch is pressed. Then enable the function by pressing the RED switch. When the RED switch is pressed, the Yellow “SYS. ISOLATED” LED will turn ON. The buzzer will also emit a short ‘beep’ once every twenty seconds to alert an operator that a function has been enabled. During System Isolation, the Panel will continue to monitor all four detection inputs. If the Panel detects a closed circuit at the FIRE ALARM INPUT, there will be no System Activation or continuous audible alarm indication. The RED “FIRE ALARM” LED will become continuously illuminated and remain “ON” as long as the Panel detects a closed circuit at the FIRE ALARM INPUT. Should the Fire Alarm Detection clear while the Panel is ISOLATED, the “FIRE ALARM” LED will automatically turn OFF. A Panel reset is not required. If the “MANUAL ACTIVATION” SWITCH is pressed, it will also turn ON the “FIRE ALARM” LED and will turn OFF the “FIRE ALARM” LED when the switch is released. If the Panel’s High Temperature Input detects a closed circuit, the RED “FIRE ALARM” LED will commence to flash once every second, together with a synchronised beep from the buzzer. This ALARM condition will continue until the temperature of the Probes return to their set open contact temperature range. SYSTEM FAULT: The Panel monitors and will identify six FAULT conditions.

• Low Cylinder Pressure

• Fire Detection Fault

• Release Fault

• Manual Activation Fault

• High Temperature Detection Fault

• Engine Shutdown Relay Fault All SYSTEM FAULTS are detected as a result of an OPEN CIRCUIT on the supervised circuits.

10

With reference to the Engine Shutdown Relay Fault, the Panel monitors the Relay Coil for an open circuit of the coil or an open circuit connection to the coil. It also monitors for a loss of voltage to the Relay Coil. If any of these faults are detected and identified, the Panel must be sent to the Supplier for repair or replacement. With reference to the Release Fault, the Panel also monitors for a loss of the 12v supply voltage to the Solenoid or Metron and will also detect if 24v is applied to the Solenoid coil or Metron. The Panel will latch and continuously illuminate the YELLOW “SYS. FAULT” LED and the buzzer will also commence to emit an audible tone once every twenty seconds. The audible indication may be muted by momentarily pressing the Panel’s RED switch. The EXTERNAL ALARM RELAY will only energise upon detection of a LOW CYLINDER PRESSUE or an open circuit to the Cylinder Pressure Switch. FAULT IDENTIFICATION: Each System Fault can be identified both visually and audibly in the following manner. Press and hold down the Panel’s RED switch. Ignore the illuminated “MUTED” LED as this diagnostic procedure overrides mute. After approximately six seconds, the buzzer will emit a series of ‘beeps’, together with synchronized OFF/ON flashes of the YELLOW “SYS. FAULT” LED. To identify the fault condition, refer to the FAULT CODES as listed below.

• 2 beeps: Low Cylinder Pressure.

• 3 beeps: Fire Detection Fault.

• 4 beeps: Release Fault.

• 5 beeps: Manual Activation Fault.

• 6 beeps: High Temperature Detection Fault.

• 10 beeps: Engine Shutdown Relay Fault. If there is more than one fault, they will be identified in ascending order. The first fault that is identified must be rectified before the next fault, which will have a higher number of ‘beep’s, can be identified.

11

If the “SYS. FAULT” LED is “ON”, but there are no beeps when the switch is held down, it means that a fault had been detected but it has cleared. The Panel may now be RESET. ALL faults must be identified and rectified before the Panel can be RESET. The cable which connects the Controller Unit to the Interface Unit is supervised. If the cable is faulty, damaged, or disconnected, the Panel will display a “SYS. FAULT” Indication. If there are no visible signs of damage to the cable and the Panel cannot be reset. The Panel will only identify the fault with the least number of ’beeps’, most likely a Cylinder Pressure fault. If all supervised inputs to the Panel have been checked and confirmed to be okay, then the cable or the Panel is faulty. If a cable replacement does not rectify the fault, the Panel must be returned to the supplier for repair, or replacement if the Panel is within the 2 Year warranty period of purchase. If there are no Battery Charger status indications illuminated, the Panel must be returned to the supplier for repair, or replacement if the Panel is within the 2 Year warranty period of purchase. SYSTEM FAULT RESET: It is not a requirement, but a recommendation, that the Panel’s audible fault alarm should be MUTED prior to resetting the “SYS. FAULT” Indication. . Unless MUTED, the fault alarm ‘beep’ may occur while selecting the “SYSTEM FAULT RESET” Function. This may cause an interruption or distraction to the selection procedure.

Press the BLUE switch THREE times. A short ‘beep’ will be heard each time the blue switch is pressed. Then enable the function by pressing the RED switch. When the RED switch is pressed, the Panel will reset. Now only the Panel’s Green “ON” LED will be illuminated and also one of the Battery Charger status indications. NOTE: The Panel CANNOT BE RESET by disconnecting the external power source and the internal battery connection. When powered, up the System Fault condition will remain latched. Only the above reset procedure will reset the System Fault.

TESTING

12

THERE ARE TWO METHODS USED FOR TESTING THE PANEL. METHOD ONE: The panel may be tested on a routine basis to verify that the Panel is functioning normally. There will be no Release Output Activation to disperse the fire suppressant when using this test method Press and hold down the Panel’s RED switch for approximately five seconds until the GREEN “TESTING” LED becomes illuminated and the buzzer emits a continuous audible tone. Then release the RED switch. . The EXTERNAL ALARM relay will become energised and the following status indicating LED’s will become continuously illuminated: RED “FIRE ALARM”, RED “SYS. DISCHARGED”, YELLOW “SYS. FAULT” and YELLOW “SYS. ISOLATED”. The engine shutdown timing sequence will commence and continue for the time period as set by the DELAY jumper link. The continuous audible alarm indication will change to a rapid pulsing tone approximately three seconds prior to energising the ENG. SHUTDOWN Relay and illuminating the RED “ENG. SHUTDOWN” LED. At the completion of engine shutdown, the buzzer will mute and then commence to emit a one second tone every twenty seconds. This now completes the testing procedure. A momentary press of the Panel’s RED switch will reset the Panel Now only the Panel’s Green “ON” LED will be illuminated and also one of the Battery Charger status indications. This test procedure may be used to verify the Engine Shutdown Delay Setting without having to remove the Controller lid to visually check the DELAY Jumper setting. METHOD TWO: SYSTEM ELECTRICAL TEST ACTIVATION. The Panel may be tested at the completion of an installation and on a routine maintenance basis to verify that the Panel is functional and that IT WILL ACTIVATE THE LATCHING SOLENOID OR METRON, which disperses the fire suppressant. A “Solenoid/Metron Activation Tester” must first be connected in place of the Solenoid or Metron. Select the Solenoid or Metron option on the Tester. Disconnect the Solenoid or Metron and connect the cable to the Tester. The Panel will detect and indicate that there has been a System Fault. Therefore, the “SYS. FAULT” must be RESET prior to commencing the “TESTING” Procedure, as described below.

Press the BLUE switch FIVE times. A short ‘beep’ will be heard each time the blue switch is pressed. Then enable the function by pressing the RED switch. When the RED switch is pressed, the Panel will commence to rapidly flash the GREEN “TESTING” LED. While the “TESTING” LED is flashing, press and hold down the Panel’s RED switch for approximately five seconds until the “TESTING” LED changes to a steady illumination and the buzzer emits a continuous audible tone. Then release the RED switch.

13

The Panel will be carry out the same Test procedure as described in METHOD ONE, with the exception that a Tester will display the result of the TEST. If testing a system which uses a Latching Solenoid, the Tester must remain connected for at least thirty seconds for it to detect the Solenoid Reset Pulse. If the Panel’s activation circuit is functioning normally, the Tester will illuminate and latch a green “OK” LED and also a Yellow “SOLENOID RESET” LED. If testing a system which uses a Metron, the Tester will only illuminate the green “OK” LED. This indicates that the Panel’s activation circuit is functioning normally. RESET the tester on completion of testing. Disconnect the Tester and reconnect the Solenoid or the Metron. The Panel will again detect and indicate that there has been a System Fault. RESET the Panel. Now only the Panel’s Green “ON” LED will be illuminated and also one of the Battery Charger status indications.

COVERT FAULT INDICATION

16

The “COVERT FAULT INDICATION” is generated when the Panel detects a fault on the Release output circuit and also when there has been a System activation. When there has been a System Activation, the Panel will illuminate and latch “ON” the small Yellow SMT LED, DS1. Refer to FIG 5 on PAGE 15. The LED is latched ON when the Solenoid or the Metron is energised. After approximately 20 seconds after activation, the Panel will automatically RESET the “COVERT FAULT INDICATION”. However, when the Panel has detected a Release Fault, the LED is permanently latched “ON” until MANUALLY RESET by pressing the tactile switch SW3 which is located next to the LED. Refer to FIG 5 on PAGE 15. The Panel will display and identify the Release Fault on the Controller Unit as described on Page 10 and the procedure for resetting the Panel when the fault condition has been rectified, is described on Page 11. The “COVERT FAULT INDICATION” will NOT RESET when the “SYS. FAULT” indication on the Panel, is RESET. The purpose for this feature is to identify weather the Panel is responsible for a failed or accidental SYSTEM ACTIVATION. EXAMPLES 1 AND 2

1. FAILED SYSTEM ACTIVATION: A fire has been detected by the Panel but there was no release of fire suppressant. All indications on the Controller Unit shows that the Panel did initiate System Activation. If the DS1 LED inside the Interface Unit is ‘NOT’ illuminated, it means that The Panel’s RELEASE OUTPUT DID function and DID reset the “COVERT FAULT INDICATION”. To validate this statement, the Panel must be tested to confirm that all functions are operating as per the OPERATIONAL descriptions within this manual.

2. ACCIDENTAL SYSTEM ACTIVATION: A customer claims that the Panel was responsible for a discharge of fire suppressant. If the LED DS1 inside the Interface Unit ‘IS’ illuminated, it means that the Panel did ‘NOT’ initiate a RELEASE OUTPUT to the Latching Relay or Metron. To validate this statement, the Panel must be tested to confirm that all functions are operating as per the OPERATIONAL descriptions within this manual . The “COVERT FAULT INDICATION” is only useful if the Indication has been RESET after System Installation and Commissioning and also after routine maintenance checks.

INSTALLATION

Mount the Panel Controller Unit in a suitable location utilising the supplied stainless steel bracket. Ensure that the Panel will not sustain external damage when mounted in a confined space.

17

The standard length of the pre-wired interconnecting cable is 2 meters. The connectors on the cable have a reliable “push-pull” lock mechanism. The white arrow markings on the plugs face up to align with the markings on the housing sockets. Ensure that the connectors are pushed in firmly until locked into position . There are four M6 threaded screw mounting points on the back of the Interface housing for securing onto a fabricated mounting bracket as required. Switch Settings, Jumper Settings and Fault Codes are printed on the decal of the Interface Unit. For connections to the Panel “Interface Unit’s” wiring loom, refer to “CONNECTOR WIRING” on page 20 and the ”WIRING DIAGRAM” on page 21. The Wiring Loom to the Interface Unit comes with Deutsch Connectors fitted as shown in the Image below. Ensure that the power cable to the Panel is wired directly to the vehicle’s battery terminals, and install a 3 Amp fuse close to the battery’s positive terminal. Use a weather resistant fuse holder to ensure no moisture or dirt ingress into the fuse holder. Wiring the Panel’s External Power Input directly to the vehicle’s battery will ensure that there will be minimal external power interruption to the Panel so that the Panel’s Internal Backup Battery maintains a healthy charge . NOTE: When initially connected, the internal backup battery won’t “Power Up” the Panel when there is no external power applied to the Panel. Once external power is applied, the battery becomes enabled

The battery also becomes enabled if it is connected after the main external power has been applied to the Panel.

1. 2. 3. 4. Starting from the left-hand side, the connectors shown in the Image above are as follows:

1. DC Voltage Input. 2. Four Detection Inputs. 3. Solenoid or Metron Activation Output. 4. Engine Shutdown Relay and External Alarm Relay Outputs.

All wiring to the Panel’s selected Detection Inputs, except for the Cylinder Pressure input, must be terminated with an End of Line Resistor with a value of 4.7k Ohm. The Images below show the End of Line Resistor and the ELR Housing which is supplied with each Panel.

18

END OF LINE RESISTOR 4.7K OHM ELR HOUSING It is extremely important that the correct polarity is observed when connecting the wiring to the Solenoid Coil terminals. If the polarity is reversed, the Solenoid will not latch until the Panel initiates the Solenoid Reset Pulse, which occurs 20 seconds after the Activation Pulse that should latch the Solenoid. On the Interface Unit cable, Pin 1 of the Male Deutsch Connector is Positive Polarity. It must be wired to the Solenoid Coil terminal with the + sign. Refer to “INTERFACE UNIT CONNECTOR WIRING”, PAGES 20 and 21. The Image below shows the polarity markings on the Solenoid Coil.

SOLENOID COIL POLARITY SOLENOID CONNECTOR

Refer to “SETTINGS” on Page 14 and confirm that ALL Switches and Jumpers are correctly configured to meet

the installation requirement.

Refer to the “ENGINE SHUTDOWN” Delay description on Page 7 and the Jumper location as shown in FIG 1, Page 15.

19

Refer to the “MANUAL ACTIVATION” and HIGH TEMPERATURE DETECTION” descriptions on Pages 8 and 9. FIG 1 on Page 15 shows the Jumper locations. Refer to “FIRE ALARM DETECTION” description on Page 6 and the Jumper location as shown in FIG 3, Page 15. Confirm Solenoid or Metron Release Activation. This can be achieved by performing a Panel test as described in “METHOD TWO” on Page 12. Carry out testing from all “Input Detection” location points to ensure that the Panel is monitoring all Inputs. On completion of the Panel Installation and System Commissioning, reset the small illuminated LED (DS1) inside the Interface Unit by pressing the reset switch (SW3) which is located beside the LED. Refer to “COVERT FAULT DETECTION” on Page 16 and FIG 5 on Page 15. Also, after all routine maintenance checks, confirm that the Covert Fault Indication is reset. The Panel will still function normally as per this manual’s “OPERATION” descriptions, If the illuminated DS1 LED has not been reset. As a final test, ensure that Engine Shutdown is operational. Use the “METHOD ONE” testing mode, as described on Page 12 of this Manual.

If there are, or have been, any questionable interface issues relating to the activation of the vehicle’s engine shutdown, please contact the Fire System Supplier and the Panel Designer / Manufacturer as soon as possible to ensure that there will be no ongoing performance issues.
