Isolator Module
ISM1-2
Description
Specifi cations
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 connec-
tion. 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 a System Sensor/200 loop
• Installation in commercial installation
boxes or in the LST standard grid
• Small design
