In fire alarm systems, localized short circuits on the loop often occur and may affect the entire system.
The DC-M9503 Loop Isolator Module (hereinafter referred to as the isolator) is designed to isolate the short-circuited section from the rest of the system, ensuring normal operation of other devices and assisting in locating faulty equipment.
Once the short-circuit fault is cleared, the isolated devices will be automatically restored to the system.
This isolator is suitable for use in the Signaling Line Circuit (SLC) of addressable fire alarm systems.
Short-circuit isolation with automatic recovery after the fault is cleared
