        Overview Manuals SLC Expansion Panel Integration Degraded Operation Installation Standards

        Features:

        • Adds an addressable Signaling Line Circuit to a supported fire alarm control panel.
        • Carries a Class B Style 4 loop up to 12,500 feet over twisted, unshielded cable.
        • Uses built-in degraded mode to increase loop survivability within the supported panel arrangement.
        Honeywell NOTIFIER LCM-320 extends panel loop capacity without turning addressable devices into individual home-run circuits.

        In AFP-2800 systems, the LCM-320 establishes odd-numbered loops and companion expansion modules provide the corresponding even-numbered loops.

        Protocol selection, current budgeting, chassis placement, and loop wiring are resolved against the host panel before the plug-in module is commissioned.

        The Honeywell NOTIFIER LCM-320 Signaling Line Circuit Loop Control Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Honeywell NOTIFIER LCM-320 Signaling Line Circuit Loop Control Module Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        Addressable Loop Extension

        • Added circuit: The module contributes another Signaling Line Circuit to the host fire alarm panel.
        • Class B reach: A Style 4 loop can extend to 12,500 feet over the specified cable.
        • Cable type: The documented Class B path uses twisted, unshielded conductors.
        • Multiple loops: Plug-in construction permits several loop modules within a compact panel enclosure.

        Odd-and-Even Loop Arrangement

        • LCM positions: AFP-2800 systems assign the LCM-320 to loops 1, 3, 5, 7, or 9.
        • Expansion positions: Companion LEM-320 hardware supplies loops 2, 4, 6, 8, or 10.
        • Protocol choice: CLIP or FlashScan operation depends on the panel and system configuration.
        • Current budget: SMX+ documentation assigns 0.130 A to each LCM-320 in the panel calculation.

        Survivability Within the Loop Path

        • Built-in mode: The module includes degraded mode without requiring an external adapter.
        • Published purpose: Honeywell identifies the degraded mode as increasing survivability.
        • Panel boundary: The mode remains part of the host-panel and configured-loop arrangement.
        • Fault isolation: Loop and panel diagnostics must still be read together when normal processing is interrupted.

        Plug-in Hardware and Approvals

        • Mechanical format: The module installs as a plug-in card in the supported panel hardware.
        • Enclosure density: Multiple loops can be placed in one enclosure without separate standalone controllers.
        • Approval set: Published approvals include UL/ULC, FM, CSFM, and FDNY.
        • Selection check: Panel model, loop number, protocol, and current budget must agree before installation.
        Description
        Honeywell NOTIFIER LCM-320 is a plug-in loop control module that adds a Signaling Line Circuit to a supported fire alarm control panel. The added loop carries addressable device communication while the panel retains supervision and control of the connected circuit.

        For a Class B Style 4 installation, Honeywell NOTIFIER LCM-320 supports a twisted, unshielded SLC run up to 12,500 feet. In AFP-2800 arrangements, the module occupies odd-numbered loop positions, while companion expansion hardware supplies the paired even-numbered loops.

        The built-in degraded mode of Honeywell NOTIFIER LCM-320 increases loop survivability within the supported panel arrangement. Its plug-in construction allows multiple loops to be assembled in a compact enclosure without converting the SLC into separate point-to-point wiring.

        Protocol handling for Honeywell NOTIFIER LCM-320 depends on the host panel configuration and can include CLIP or FlashScan operation. The documented approvals apply to the loop-control hardware, while panel selection determines the available device protocol and loop count.

        Technical notes
        Honeywell NOTIFIER LCM-320 supplies an additional SLC loop, with loop length, protocol, and numbering determined by the host-panel arrangement.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        How is Honeywell NOTIFIER LCM-320 assigned in an AFP-2800 panel?
        In an AFP-2800 panel, Honeywell NOTIFIER LCM-320 occupies odd-numbered loops 1, 3, 5, 7, or 9 while LEM-320 supplies the paired even-numbered loops.
        What cable path is documented for Honeywell NOTIFIER LCM-320?
        A Class B Style 4 SLC for Honeywell NOTIFIER LCM-320 can extend to 12,500 feet over twisted, unshielded conductors.
        Does Honeywell NOTIFIER LCM-320 determine whether CLIP or FlashScan is used?
        No. Although Honeywell NOTIFIER LCM-320 can participate in CLIP or FlashScan operation, the host-panel configuration determines the available protocol.
        Why must panel current be recalculated when adding Honeywell NOTIFIER LCM-320?
        Each Honeywell NOTIFIER LCM-320 contributes 0.130 A in the documented SMX+ calculation, so adding a loop changes the panel power budget.
        What does degraded mode change for Honeywell NOTIFIER LCM-320?
        Honeywell identifies the built-in degraded mode of Honeywell NOTIFIER LCM-320 as increasing survivability; it does not remove the need to diagnose a panel fault.
