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:
• Normal Standby =56 mA
• Maximum=65 mA
The Normal Standby Current is used for battery size calculations (see the FA-300 Series or
FX-350/351 Series Fire Alarm Control Panel manual for battery calculations) 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 Wiring section above).
