NOTES:
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 combi-
nation 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.
2. For NFPA 72 Remote
Station connections,
provide 60 hour
battery backup.
