NOTE:
1. In addition to deter-
mining the required
battery size, consider-
ation must be given to
the overall current
drawn by the system.
The total system
current capability is
3.5 amps at 24 volts.
The total alarm
current must not
exceed 3.5 amps for
any combination of
the basic system plus
any additional
modules used. When
installing additional
modules, the current
available for the NAC
circuits and auxiliary
port must be derated
to keep the total alarm
current below 3.5 amps.
