Current Drain for Battery Calculations

The following are the currents for the RAX-LCD to which is added the number of RAX-
1048TZDS and/or IPS-2424DS used:
Normal Standby Current = 100 mA+ [________ X 15 mA] + [________ X 10mA] =_______
Maximum = 150 mA+ [___________ X 15 mA] + [_________ X 144mA] = __________
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 4).
