Current Drain for Battery Calculations

The maximum normal current drain will be during Lamp Test when all lamps are illuminated on
one chassis at a time. Thus the currents are as follows:
Normal Standby
Current = 35 mA
The Normal Standby Current is used for Battery Size Calculations (see the Fire Alarm
Control Panel manual) and includes the current drain for the Trouble Buzzer, Trouble LED,
and one Alarm LED. The Maximum Current is used to calculate the wire size (see the Wiring
Instruction).
