NOTIFIER HS-NCM-W-2 — a High-Speed Network Communications Module with a twisted-pair wire interface, for connecting NOTIFIER panels and annunciators to High-Speed NOTI·FIRE·NET™.
The HS-NCM provides NOTIFIER’s N16, NFS-320, NFS-640, NFS2-640, NFS-3030 and NFS2-3030 Fire Alarm Control Panels, NCD, NCA and NCA-2 Network Control Displays and Annunciators, and DVC Digital Voice Command with a means to connect to High-Speed NOTI·FIRE·NET. Each HS-NCM can accommodate up to two node addresses — one module can, for example, provide network communication for both an N16 and an NCD.
Transformer coupling provides electrical isolation between nodes, and a pluggable service connector feeds the signal directly through in the event that power must be removed from a node, so pulling one panel does not break the network. When not connected to a fire alarm panel, the HS-NCM defaults to repeater mode and can be used to boost signal distances or to pass data transmissions between two differently configured network segments where wire and fiber co-exist.

Installation notes
-
Port-to-port wiring is polarity sensitive: when wiring consecutive HS-NCM-W-2 boards, wiring may enter or exit at Port A or Port B, but the use of Port A or Port B is not arbitrary. Get the polarity and port pairing right or the segment will not communicate.
-
Connect only to wire-capable modules: an HS-NCM-W-2 may be connected to another HS-NCM-W-2 in another panel, or to an HS-NCM-WMF-2 or HS-NCM-WSF-2. Reaching a fiber-only node requires one of the combination modules.
-
Not a drop-in for the older HS-NCM-W: the HS-NCM-W-2 is compatible with the obsolete HS-NCM-W, HS-NCM-WMF and HS-NCM-WSF, but a different configuration is required.
-
Ground fault detection is switch-selected: set SW4-1 ON for Channel A and SW4-2 for Channel B.
-
Mounting: installs in any standard chassis such as the CHS-4L, CHS-M2, CHS-M3, CHS-4N or CPU2-640 chassis. The HS-NCM-W-2 can additionally be door-mounted on the ADP-4B dress panel on a BMP-1 single-space blank plate in a CAB-4 Series cabinet, or on the DP-4A / DP-T2A dress panel on an ABP-1 blank plate in a CAB-5 Series cabinet.
-
Documentation: correct configuration depends on network design — refer to the High-Speed NFN Manual, P/N 54013, and the HS-NCM Manual, P/N 54014.

FAQ
Which panels can use the HS-NCM-W-2?
It connects NOTIFIER N16, NFS-320, NFS-640, NFS2-640, NFS-3030 and NFS2-3030 panels, NCD, NCA and NCA-2 displays and annunciators, and the DVC to High-Speed NOTI•FIRE•NET.
How far apart can network nodes be?
Up to 3,000 ft (914.4 m) between nodes, point to point. Actual distance varies with wire quality.
Is it compatible with the older HS-NCM-W?
Yes. Notifier lists the obsolete HS-NCM-W, HS-NCM-WMF and HS-NCM-WSF as compatible, but a different configuration is required.
What power does it need?
24 VDC at 400 mA. Each module can serve up to two node addresses.
