Information About LEM-320
The LEM-320 is a loop expander module engineered for use with NOTIFIER’s ONYX Series fire alarm control panels. It mounts directly to the LCM-320, enabling the addition of SLC loops for expanded system coverage. This module is compatible with the NFS2-3030 and NFS-640 panels, supporting efficient Class B (Style 4) wiring configurations. Built with plug-in simplicity, the LEM-320 is suitable for fire protection applications where scalable loop capacity is required.
Key Features:
- Loop Expansion: Adds extra SLC loops to compatible LCM-320 modules.
- Long Wiring Distance: Supports up to 12,500 feet (3,810 m) with 12 AWG twisted unshielded wire.
- Degraded Mode Operation: Ensures survivability in case of partial system failure.
- Compact Form Factor: Installs as a daughter board within small enclosures.
- High Compatibility: Works with NFS2-3030 and NFS-640 control panels.
- Simple Installation: Plug-in mounting design reduces setup time.
- UL, FM, and CSFM Approved: Certified for fire protection applications.
- Reliable Power Performance: Operates at 24 VDC nominal (27.6 VDC max).
The LEM-320 delivers the reliability and precision required for modern fire alarm and life safety systems.
