Standby current [A]
Alarm current [A]
If the total current of the outputs (Sounders, etc.) is higher than
10
00
mA
, then an
external power supply is required. In order to reduce the total current:
- Power the output A&B from the external power supply (possible per card).
-
Move the Auxiliary output to the external power supply.
Choose the appropriate battery size depending on the calculated capacity.
[(Standby time × Standby current) + (Alarm time × sum alarm current)] × Aging factor = Capacity (max. 17 Ah)
_ _ h × 0._ _ _ A + 0.5 h × _._ _ _ A × 1.25 =
Standby time [h]: 24, 30 or 72
Alarm time [h]: 0.5 hour
Aging factor: 1.25
Standby current [A]: Total current in standby mode
Alarm current [A]: Total current in alarm mode
Capacity [Ah]: 7 Ah; 12 Ah; 17 Ah
