STANDBY BATTERY CALCULATION
Battery capacity
should be between 2 x 2.4 Ah 12V DC and 2 x 7 Ah 12V DC.
The battery Ah required for a given installation is calculated from the following formula:
(
38mA
X
Standby time
required in hours
divided by 1000
)
+
(
Alarm & Aux. Supply
Outputs in Amps
(sounder & aux. supply load)
X
Alarm time in
hours
)
+ 20%
Round the result to the next available battery size. Quiescent current of the panel with everything is found by adding the
standby current of all connected devices to the standby current of the panel (38mA). Consult the manual for the individual
devices to confirm the standby current.
Troubleshooting - Fault Indications
Troubleshooting work of any fault on the panel should only be carried out by qualified technicians.
General Fault
The General fault LED is illuminated whenever there is a fault on the system. It is always lit along with at least one other fault
indicator which gives more detail relating to the fault.
Power Supply Faults - Supply Fault
Associated with a low voltage (below 20V) present at the input of the power supply or the removal of the main power supply.
Measure voltage levels and verify electrical mains fuse.
Battery Fault
This fault is present when there is a voltage below 20 V DC at the battery terminals or if there is a battery charger problem.
Charger problems can be caused by panel's hardware failure or batteries that have not been connected in the specified
manner as indicated in this manual, in the installation section. Verify if batteries are properly connected. Measure the voltage
at the battery terminals and replace if it is below 21V DC. Remember to verify also the main electrical fuse.
DON'T SHORT CIRCUIT BATTERY TERMINALS IN ORDER TO VERIFY BATTERY CHARGE ONLY USE
BATTERIES THAT ARE LEAD ACID VRLA TYPE 12VDC.
Aux Supply Fault
This fault will show when the voltage at the auxiliary supply output is below 20 Volts DC. This can be caused by the current
limit for this output being exceeded. This output is limited to 900mA. Other causes for faults at this point are short circuits in
the wiring or faulty hardware attached to this supply output. Verify voltage, if below the required acceptable level remove
wiring connected to this output. If voltage now returns to normal this confirms that connected equipment or cable is
damaged.
Earth Fault
This FAULT will indicate that there is some level of current leakage between any of the wire conductors and the EARTH
connections. VERIFY WIRING.
System Fault
This FAULT indicates that there is a fault at the main processor level. In this particular fault, the panel's main board needs to
be replaced or repaired.
