• Annunciation of up to 48 additional points (with trouble annunciation on the TZ
version).
• Standby: 15 mA Max., All LEDs “On”: 100 mA Max.

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:
Normal Standby Current
= 50 mA+ ______________ X 15 mA = _________
(number of adder chassis)
Maximum
= 150 mA+ ______________ X 15 mA= _________
(number of adder chassis)
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
Wiring Instructions
on page 3).
