Isolator Module/Anal./Apo ISM1-3

The Isolator Module ISM1-3 is used on the ADM loop with 

Apollo/Discovery 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 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.
