Notifier NCM-F Network Control Module.

The NCM-F NOTIFIER Network Communications Module (NCM) provides NOTIFIER’s NFS-640, NFS-3030, and NFS2-3030 Fire Alarm Control Panels, and NCA and NCA-2 Network Control Annunciators with a means to connect to NOTI•FIRE•NET™. Two types of NCM are available: NCM-W for connecting nodes with twisted pair wire, and NCM-F for connecting nodes with fiber-optic cable. NCM-F Interconnections: When wiring consecutive nodes/repeaters, fiber cable must exit one board on Transmit (TX) and enter the next node/repeater on Receive (RX). The fiber-optic pair (RX, TX) from Port A of one node/repeater may be connected to either Port A or Port B of another node/repeater. An NCM-F may be connected to any of the following devices: MIB-F, MIB-WF, NAM-232F, another NCM-F, NCS-F network connection, RPT-F, RPT-WF. Both NCM-W and NCM-F can be installed in any standard chassis such as the CHS-4L, CHS-M2, CHS-M3 or CHS-4N (see panel sheets). Additionally, the NCM-W can be door-mounted on the ADP-4B dress panel on a single-space blank plate (BMP-1) for mounting in an CAB-4 Series cabinet.
