Notifier NCM-W Network Communications Modules

General
The Network Communications Module (NCM) provides NOTI￾FIER’s intelligent Fire Alarm Control Panels, and NCA and
NCA-2 Network Control Annunciators with a means to connect
to NOTI FIRENET. 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.
• Transformer coupling provides electrical isolation between
nodes.
• Pluggable terminal wiring with strain relief.
• Pluggable service connector (feeds signal directly through) in
the event that power must be removed from a node.
• 312.5 Kbaud transmission rate.
• Data is regenerated at each node.
• Two network ports to allow simultaneous connection to fire
alarm control panel and to programming computer.
• Repeaters are available to increase signal.
• Repeaters may be utilized to switch media type.
• Up to 3,000 feet (914.4 m) between nodes in a point-to-point
fashion (actual distance varies with wire quality)
