The monitor and control module FI700/M1IN1REL is integrated into a loop with Labor Strauss protocol and provides both a line-monitored input for the connection of contact detectors as well as a dry relay output for the actuation of external devices. With that, various devices such as manual call points, supervising contacts, signalling devices or solenoid valves can be easily integrated into a fire detection system with loop
technology. The integrated dual-isolator disconnects the loop at short circuit on the loop line.
