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, and NCA and NCA-2 Network Control Annunciators with a means to connect to High-Speed NOTI•FIRE•NET™. Six types of HS-NCM are available: HS-NCM-W for connecting nodes with twisted-pair wire, HS-NCM-MF for connecting nodes with multi-mode fiber-optic cable, HS-NCM-SF for connecting nodes with single-mode fiber-optic cable, HS-NCM-WMF for connecting wire and multi-mode fiber-optic medium on the same network, HS-NCM-WSF for connecting wire and single-mode fiber-optic mediums on the same network and HS-NCM-MFSF for connecting multi-mode and single-mode fiber optic mediums on the same network.
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.
