Current Drain for Battery Calculations
The following are the currents for the RAX-LCD to which is added the number of RAX-1048TZ
and/or IPS-2424 used:
Normal Standby Current
= 1000 mA+ ________ X 15 mA = ________ X 10mA =_______
(number of RAX-1048TZ)(number of IPS-2424
)
Maximum
= 150 mA+ ___________ X 15 mA= _________ X 144mA = __________
(number of RAX-1048TZ)(number of IPS-2424)
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 12).
