Notifier HS-NCM-W-2 High-Speed Network Communications Module twisted-pair wire interface.

The High-Speed Network Communications Module (HS-NCM) provides NOTIFIER’s NFS-320, NFS-640, NFS2-640, NFS-3030, and NFS2-3030 Fire Alarm Control Panels, NCA and NCA-2 Network Control Annunciators, and DVC Digital Voice Command with a means to connect to High-Speed NOTI•FIRE•NET (NFN).

Each HS-NCM can accommodate up to two node addresses. For example, one HS-NCM can provide network communication for both an NFS2-640 and an NCA-2.

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 when wire and fiber co-exist on a network.
