Honeywell NOTIFIER LEM-320 Loop Expander Module
The NOTIFIER LEM-320 is a plug-in loop expansion module designed to add an additional Signaling Line Circuit (SLC) to compatible Honeywell NOTIFIER ONYX Series fire alarm control panels. It expands the NFS-640 and NFS2-640 from one loop to two, and can expand each compatible LCM-320 loop in NFS-3030 and NFS2-3030 systems. Its built-in degraded-mode capability, compact plug-in design, and support for long SLC wiring distances make it useful for addressable fire alarm installations that require additional loop capacity.

Honeywell NOTIFIER LEM-320 Loop Expander Module Supplier in Saudi Arabia Product Description
The Honeywell NOTIFIER LEM-320 Loop Expander Module is an addressable fire alarm system expansion component designed to provide additional Signaling Line Circuit (SLC) capacity in compatible NOTIFIER ONYX Series fire alarm control panels. It works with the NFS-640 and NFS2-640 control panels to add a second SLC loop and with compatible LCM-320 modules in NFS-3030 and NFS2-3030 systems to expand loop capacity. This enables supported systems to connect with additional compatible addressable detectors, monitor modules, and control modules, subject to the panel’s approved configuration.
The LEM-320 features a convenient plug-in installation design, built-in degraded-mode operation to help improve system survivability, and support for SLC wiring distances of up to 12,500 feet (3,810 metres) using 12 AWG twisted, unshielded pair cable in a Class B (Style 4) configuration. Designed for use in commercial buildings, industrial facilities, and infrastructure projects, the module helps expand addressable fire alarm system capacity while maintaining integration with compatible NOTIFIER control equipment. Confirm panel compatibility, wiring requirements, and applicable approvals before installation or replacement.
AED Arabia supplies Honeywell NOTIFIER Fire & Life Safety products for projects across Saudi Arabia, including the Honeywell NOTIFIER LEM-320 Loop Expander Module and Honeywell NOTIFIER LCM-320 Loop Control Module, designed for compatible intelligent addressable fire alarm systems and loop management applications.
