2.21 Built-in Short-circuit Isolator
The loop resistance on the detection loop is continously monitored to
register a possible break or short-circuit on the detection loop. Each
individual detector has a built-in short-circuit isolator.
In the event of a short-circuit in the detector cable, the short-circuit
location will be isolated as the short-circuit isolator will be activated in
the detectors on either side.
