BATTERY REQUIREMENTS
The battery AH required are calculated from the following formula:
Round up to the next available battery size.
Quiescent currents for individual equipments are listed below:
NOTE:
For 2 loop panels 7AH batteries are always recommended.
Quiescent current in mA of
the panel with everything
connected.
Alarm current in Amps
(sounder load)
Standby time required in
hours divided by 1000.

Example
A given installation has a single loop panel with 58 mA detector load, 1.4 A sounder load (including loop
sounders) and a 24 hour standby requirement.
Quiescent current in
mA of the panel with
everything connected.
Alarm current in Amps
