NOTES:
NOTE 1: ** 24 hrs for NFPA 72 protected premises or Central Station signaling, or Auxiliary, or Remote Supervising
Station Fire Alarm Systems.
NOTE 2: *** Use the next size battery with a capacity greater than required. (Use only Gamewell-FCI Models: B-1,
B-7R, B-17R, B-55R, BAT-1270, BAT-12120, BAT-12260, or BAT-12550 batteries). The maximum standby current for
60 hours when using 55 A/H batteries is .560 A. The system batteries must be replaced as a set.
NOTE 3:
£ Normal operating current. During power failure, current
drops to 0.045 amp since back light is extinguished.
NOTE 4:
† Add .003 amp for any LED to be lit
for any condition when powered internally.
NOTE 5:
‡ Add .003 amp for any LED to be lit for any condition when powered internally. When powered externally, a
max. output current of .050/point is available for a maximum total output of 2.4 amp/ANU-48.
NOTE 6: Continuous standby loads in excess of .560 Amps up to 5 Amps may require Generator Backup or load
shedding during an AC power failure.
Note 7: Continuous standby loads in excess of .560 Amps up to 4 Amps may require a Generator Backup or load
shedding during an AC power failure.
