— DN-6861:C•A0-260 • NCM-W, NCM-F ONYX® Series ® NOTIFIER® Network Communications Modules by Honeywell Network Systems General The Network Communications Module (NCM) provides NOTIFIER Intelligent Fire Alarm Control Panels, and NCA and NCA-2 Network Control Annunciators with a means to connect • t,, , to NOTI•FIRE•NETTM. Two types of NCM are available: NCM-W for connecting nodes with twisted-pair wire, and NCM-F for connecting nodes with fiber-optic cable. NOTE: Do not mix NCM and High Speed(HS)NCM on the same system. NCM-W Features • Supports twisted-pair wire medium. • NFPA Style 4(Class B)operation or NFPA Style 7(Class A) operation. • Two programmable data thresholds. NCM-W • Transformer coupling provides electrical isolation between • Maximum attenuation is 8 dB with 62.5/125 pm fiber and nodes. 4.2 dB with 50/125 pm fiber. • Pluggable terminal wiring with strain relief. • Wavelength (1): 820 nanometers (use standard 850 nm • Pluggable service connector(feeds signal directly through) fiber). in the event that power must be removed from a node. • Connectors:ST®style. • 312.5 Kbaud transmission rate. • 312.5 Kbaud transmission rate. • Data is regenerated at each node. • Data is regenerated at each node. • Two network ports to allow simultaneous connection to fire • Two network ports to allow simultaneous connection to fire alarm control panel and to programming computer. alarm control panel and to programming computer. • Enables software and database upload/download over • Enables software and database upload/download over NOTI•FIRE•NETTM.
