Description
The 683 addressable audio/visual alarm base is a
loop-powered device that provides a fire alarm
warning to building occupants. The integration of
the audio/visual function with a detector base may
displace the need to install separate audio/visual
alarm devices.
Models with an integrated isolator provides
electrical isolation of loop wiring for addressable
ifre detection control and indicating equipment.
The isolator function ensures that short-circuit
faults in the alarm zone loop wiring disables a
minimum number of devices.
