The Isolator Module ISM1-2 is used on the ADM loop with System Sensor/200 protocol and disconnects the loop in the event of a short circuit of the loop connection. Thereby only the loop elements located between two isolator modules are affected by the short circuit. The Fire Detection Control Panels Series BC600 and BC216 report the affected loop elements as faulty and operate the remaining loop sections, which are not faulty, from both ends of the loop, until the fault is removed.
