NOTIFIER LEM-320 Loop Expander Module

Loop Expander Module.  Mounts as daughter board to LCM-320 to provide even numbered SLC loops.

LEM-320: Loop Expander Module. Expands each LCM used on the NFS-3030/NFS2-3030; expands NFS-640/NFS2-640 to two loops.


The LCM-320 Loop Control Module and the LEM-320 Loop Expander Module provide NOTIFIER’s ONYX® Series of Fire Alarm Control Panels (FACPs) with Signaling Line Circuits (SLCs). The ONYX® Series NFS-640/NFS2-640 supports one LEM-320; the NFS-3030/NFS2-3030 supports up to five LCM320s and five LEM-320s.

The LEM-320 module is used to expand the NFS-640/NFS2-640 to a second loop, and to expand each LCM-320 used on the NFS-3030/NFS2-3030 — each NFS-3030/NFS2-3030 LCM-320 supports an expansion LEM-320.


• Up to 12,500 feet (3,810 m) on a Class B (Style 4) SLC loop (twisted-unshielded).

• Built-in degraded mode increases survivability.

• Very simple installation — plug-in style.

• Permits multiple loops in small enclosure
