Notifier LCM-320 Loop Control Module

The Notifier LCM-320 is a loop control module that provides Notifier's ONYX Series fire alarm control panels with additional Signaling Line Circuits (SLCs). The NFS-3030 and NFS2-3030 panels support up to five LCM-320 modules, and each LCM-320 can be expanded to two loops by adding a LEM-320 Loop Expander Module.

The module supports SLC wiring distances up to 12,500 feet (3,810 m) on a Class B (Style 4) loop using twisted-unshielded wire. A built-in degraded mode increases system survivability, and the plug-in design simplifies installation. The LCM-320 permits multiple loops in a compact enclosure, operates at 24 VDC nominal (27.6 VDC maximum), and is UL/ULC-listed and FM approved.
