The High-Speed Network Communications Module (HS-NCM) provides NOTIFIER®’s N16, NFS-320, NFS-640, NFS2-640, NFS3030, 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™ (NFN). Six types of HS-NCM are available:
• 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-MFSF for connecting multimode and single-mode fiber optic mediums on the same network.
• HS-NCM-W-2 for connecting nodes with twisted-pair wire
• HS-NCM-WMF-2 for connecting wire and multimode fiber-optic medium on the same network
• HS-NCM-WSF-2 for connecting wire 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 N16 and an NCD.
