Labor Strauss/700 protocol and provides 4 independent line-monitored inputs for the connection of contact detectors, two line-monitored outputs as well as two independent dry relay outputs for the actuation of external devices. With that, various devices such as manual call points, supervising contacts, signaling devices or solenoid valves can be easily integrated into a fire detection system with loop technology. The load that is connected to the monitored outputs is powered by an external power supply.

The module occupies 8 consecutive addresses on the loop. The base address is set in the range 1 to 233 . by means of the Programming Unit FI750/PU. Furthermore, in case of connection to a compatible fire detection control panel, the module can also be AUTO-addressed. The integrated dual-isolator disconnects the loop at short circuit on the loop line
