Current
2.4 A PSU’s recommended for 1 to 4 loop panels.
The maximum alarm sounder current is 250 mA for each conventional sounder circuit.
The maximum quiescent current per loop is 165 mA. The loop short circuit (trip) current is 900 mA.
Battery
Internal maximum capacity 24 V / 12 AH.
Please use a minimum of 7 Ah Battery Capacity.
BATTERY REQUIREMENTS
The battery Ampere per hour “Ah” required are calculated from the following formula:
(
Quiescent current in mA
of the panel with
everything connected
X
Standby time
required in hours
divided by 1000
)
+
(
Alarm current in Amps
(sounder load)
X
Alarm time
in hours
)
+
20%
