Loop Isolator Module AI-520

Loop isolator module is loop type fire alarm system, it often occurs that partial short circuit of loop affects the whole system. This loop isolator can isolate the shorted circuit from the whole system to ensure normal operation of other parts and locate the isolated part. The isolator is applicable to all kinds of loop fire alarm systems, suitable for Class A and Class B.
