5.3 Current Drain for Battery Calculations
The lamp test feature draws the maximum normal current because it illuminates all lamps on
one chassis at a time. Thus the currents are:
Use the “normal standby current” for battery size calculations (see the fire alarm control panel
manual for battery calculations) and includes the current drain for the Trouble Buzzer, Trouble
LED, and one alarm LED. Use the “maximum current” to calculate the wire size (see the
wiring instructions on page 10).
