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.
• Safe disconnection of a faulty loop
section
• For use in an Apollo/Discovery loop
• Installation in commercial installation
boxes or in the LST standard grid
• Small design
