682 Isolator Base

Keywords: Addressable Base, Low Profile, Isolator

The 682 isolator base provides electrical isolation of alarm zone wiring for addressable fire detection control and indicating equipment. The use of the 682 as part of the alarm zone wiring ensures that short-circuit faults in the alarm zone loop wiring disable a minimum number of devices. The 682 isolator base eliminates the need for a separate isolation device where detectors are installed on the loop.
The 682 isolator base range provides fire detection and alarm system designers with a Standards-compliant, premium product for life safety and property protection applications.
