      Information

      Information

      Overview Manuals Common Applications Product Precautions
      The LCM-320 provides an addressable signaling line circuit for compatible NOTIFIER ONYX Series control panels and communicates loop-device status to the host system.
      • One SLC per LCM-320
      • Supports one LEM-320 expander
      • 24 V DC nominal operation
      • 50 ohm maximum loop resistance

      The LCM-320 operates as a plug-in loop interface with degraded-mode support and a maximum published module current of 130 mA. In NFS-3030 and NFS2-3030 systems, up to five LCM-320 modules and five associated LEM-320 expanders can provide ten SLCs. Field wiring length, conductor size, current and topology must follow the approved fire-alarm design.

      Important Notice: Confirm the LCM-320 marking, panel compatibility, SLC topology, conductor size and approved device schedule before installation.

      • Can one LCM-320 support an additional loop?
        One LCM-320 can support one LEM-320 expander, which adds a second signaling line circuit.
      • How many LCM-320 modules can an NFS2-3030 use?
        An NFS2-3030 can use up to five LCM-320 modules together with five associated LEM-320 expanders.
      • Which operating voltage is specified for LCM-320?
        The LCM-320 operates at 24 V DC nominal with a published maximum of 27.6 V DC.
      • What is the maximum current drawn by the loop controller?
        The LCM-320 loop controller draws a maximum of 130 mA, while one SLC has a published maximum current of 400 mA.
      • How much resistance can the LCM-320 loop tolerate?
        The LCM-320 supports a maximum signaling-line-circuit resistance of 50 ohms.
      • What Class B distance is allowed with 12 AWG wire?
        A Class B LCM-320 loop can reach 12,500 ft (3,810 m) when 12 AWG twisted unshielded wire is used under the published conditions.
      • What must be tested after replacing an LCM-320?
        The technician must test every affected loop device, fault indication, expander connection and degraded-mode response after replacing an LCM-320.
