The LCM-320 and the updated ELCM-320 is a 1-loop board that can support up to 99 detectors and 99 modules
in CLIP mode. The field wiring is electrically isolated from the rest of the system so that any two-ground faults on
separate loops will not cause invalid replies from devices. A short to any other system circuit will not cause
communication loss. The LCM has an earth fault detection circuit with a yellow LED displaying an earth fault
condition. ELCM modules also include a green heartbeat LED to show that the processor is working.
The LEM is an expansion board that attaches to its LCM parent providing a second loop which has the same
features as the parent loop.
