683 Audio/Visual Alarm Base

Keywords: Addressable Audio/Visual Alarm Base, Isolator

The 683 addressable audio/visual alarm base is a loop-powered device that provides a fire alarm warning to building occupants. It is suitable for connection to Numens addressable control and indicating equipment. 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 fire 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. Isolator models eliminate the need for a separate isolation device on the loop.
The 683 audio/visual alarm base range provides fire detection and alarm system designers with a Standards-compliant, premium product for life safety and property protection applications.
