The High-Speed Network Communications Module (HS-NCM) provides a means for connecting specific Notifier fire alarm control products to High-Speed NOTI•FIRE•NET. There are six types of HS-NCMs available: HS-NCM-W for connecting nodes with twisted-pair wire; HS-NCM-MF and HS-NCM-SF are used for connecting nodes with fiber-optic cable; HS-NCM-WMF and HS-NCM-WSF are used for connecting nodes with fiber-optic cables to nodes with twisted- pair wire; HS-NCM-MFSF for connecting nodes with multi-mode fiber cable to nodes with single-mode fiber cable.
