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 to NOTI-FIRE-NET™. 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 Detail Network Communication Module
NCM-W

  • 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.
  • Enables software and database upload/download over NOTI-FIRE-NET™.
  • 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).

NCM-W Interconnections: When wiring consecutive NCM-W boards, wiring may enter or exit at Port A or Port B. NCM-W port-to-port wiring is not polarity sensitive; use of Port A or Port B is arbitrary. An NCM-W may be connected to any of the following devices: MIB-W, MIB-WF, NAM-232W, NCM-W (in another panel), NCS-W network connection, RPT-W, RPT-WF.

NCM-W Switch Functions: The NCM-W provides two sets of switches to simplify network setup. Enable ground fault detection by setting “ON” switch SW103 (Channel A); switch SW101 (Channel B). Activate on-board end-of-line resistors by setting “ON” switch SW100 (Channel A); switch 102 (Channel B). NOTE: Correct configuration is dependent on network design; refer to the NOTI•FIRE•NET™ manual.

For further information and diagrams, refer to the NCM Installation Document, 51533.

NCM-F Detail Network Communication Module
NCM-F

  • Supports fiber-optic medium.
  • NFPA Style 4 (Class B) or Style 7 (Class A) operation.
  • Data is immune to all environmental noise.
  • Optical isolation prevents ground loops.
  • NOTI•FIRE•NET™ fiber-optic medium.
  • Fiber type: 62.5/125 micrometers (multimode); or 50/125 micrometers (multimode).
  • Maximum attenuation is 8 dB with 62.5/125 μm fiber and 4.2 dB with 50/125 μm fiber.
  • Wavelength (1): 820 nanometers (use standard 850 nm fiber).
  • Connectors: ST® style.
  • 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.
  • Enables software and database upload/download over NOTI-FIRE-NET™.
  • 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).

NCM-F Interconnections: When wiring consecutive nodes/ repeaters, fiber cable must exit one board on Transmit (TX) and enter the next node/repeater on Receive (RX). The fiberoptic pair (RX, TX) from Port A of one node/repeater may be connected to either Port A or Port B of another node/repeater. An NCM-F may be connected to any of the following devices: MIB-F, MIB-WF, NAM-232F, another NCM-F, NCS-F network connection, RPT-F, RPT-WF.
