ISO-X

The NOTIFIER ISO-X is an intelligent addressable fault isolator module designed for ONYX and CLIP series fire alarm control panels to automatically isolate SLC loop short circuits, preventing a single wire-to-wire fault from disabling the entire loop.
It mounts between groups of detectors/modules, opens the SLC circuit on short detection (LED blinks red), and automatically resets when the fault clears, supporting Style 4/6/7 wiring configurations.
