Standby current [A]
Alarm current [A]
If the total current of the outputs (Sounders, etc.) is higher than
500mA
, 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.12 Ah)
