1Introduction 
1.1 General Information 
The FP-08879 Digital Voltage Sensitive Relay (DVSR) provides a plug-in solution for DC power 
supply monitoring and battery isolation. When installed the FP-08879 monitors and 
automatically isolates the incoming power supply when the incoming power drops below an 
ideal operating voltage. This avoids deep discharge of batteries.

automatic low voltage cutoff

3Operations

3.1 Mounting

The Module must be mounted using the bracket supplied.

No penetrations are to be made through the casing.

The Power Control Module enclosure is rated IP65, mounting

should be away from where it may be affected by water.

3.2 Power Supply Monitoring

The FP-08879 DVSR is a multi-voltage to operate on either

12vDC or 24vDC. When the DVSR is first powered, it will automatically sample the incoming

power supply:

12vDC (7-15.9 volts)

24vDC (16 –32 volts)

The DVSR requires continuous power for 5 seconds to determine the incoming power. Once

power mode is selected, the DVSR will remain in this mode until power is disconnected.

3.3 Automatic Cutoff

Once the FP-08879 DVSR has determined the operating voltage, it will monitor the incoming

power supply. The incoming power supply must drop below operating voltage continuously

for 4 seconds before the DVSR will automatically cut off the incoming power supply.

3.4 Fire Indicator Panel (FIP)

The FIP will then switch to backup power until the primary power supply is restored.

Backup Power Control Modules are designed to provide power to the fire system for a period

of 24 hours. Actual backup power will be available based on the condition of the batteries and

this will largely be determined by machine run time.

The backup battery is charged by the primary power supply, and approx 1 hour of run time

will provide 1 hour of battery backup, if the backup batteries have been allowed to run flat.

IMPORTANT –where Sealed Lead Acid Backup Batteries (Models 8870 and 08871) have been

installed these will need to be replaced. SLA batteries will not recharge once they have run

flat. These can be swapped for FP-08872 NiMh battery pack.

When primary power is restored, the fire system will be operational, and will stay fully

operational until the backup battery is depleted.

Note that FirePro systems have a failsafe, the FirePro Generator will self-activate once the

temperature reaches 300ºC.

3.5 Cabling Requirements

The cables are marked RED on the module, and

the plugs are setup Male/Female to ensure

correct installation.

Cables are colour coded for easy identification.

When installing system, cables should be only

connected to the correctly coded cable.

4Installation

1. Ensure fire control panel is not in an alarm/fault condition.

2. The machine MUST NOT be running.

3. Unplug the Power supply to the FIP.

4. Unplug the FP-14016 Battery Lead from Battery Pack and plug into FP-08879 DVSR. The

DVSR requires a minimum of 5 seconds to allow sampling of the incoming power supply,

to determine operating voltage. This will be indicted by flashing of the LED indicator. When

sampling is complete the LED indicator will stop flashing and remain illuminated.

5. Connect the FP-08879 to a compatible Power Control Module (FP-08872/08873). The

“Charging” LED indicator will illuminate on the Power Control Module connected correctly.

6. It is now safe to connect the power supply to the FIP.

5Operation

The FP-08879 DVSR operates when the unit is installed and the Main power is active. Should

the main supply fail or drop below operating volatage, the module automatically cuts off the

primary power supply. When the primary supply has been connected the LED will illuminate

to indicate that the primary power supply is available.

When the primary supply has failed or dropped below operating volatage will flash once every

5 seconds to indicate that the primary power supply is being cut off.

If the primary power supply voltage is too high, the DVSR will flash rapidly.

6Commissioning

Commissioning should be performed after installation.

1. Ensure fire control panel is not in an alarm/fault condition.

2. Run the machine, this should allow full power to the FIP.

3. TURN OFF machine and the Lower voltage will automatically disconnect primary power

supply (depending on state of main machine battery voltage) and ensure LED indicator

begins flashing.

4. Ensure power supply to FIP automatically switches to the backup batteries. This will be

indicated by the LED on the installed Power Control Module switching off, and the FIP

should remain operational.

5. Ensure fire control panel remains operational and out of fault condition.

7Servicing and Maintenance

Inspection and servicing of the installed fire system should occur in accordance with the

relevant Australian Standards. Monitoring and operation of any installed modules should be

tested as outlined in 6. Commissioning.

8Troubleshooting

Problem

Possible Cause

Solution

LED not illuminating

Poor/Reversed connection to

vehicle battery

Incoming power Voltage not high

enough to engage DVSR

Check connection and of battery

lead and any extension cables.

Test voltage of primary power

supply.

Charge or replace primary batteries.

LED flashing rapidly

Incoming power voltage is above

upper limit of operating voltage.

Check main supply voltage.
