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

• 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 (Chan- nel B). Activate on-board end-of-line resistors by setting “ON” switch SW100 (Channel A); switch 102 (Channel B). NOTE: Cor- rect configuration is dependent on network design; refer to the NOTI•FIRE•NET™ Network manual.

• 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™ Network 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.

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 fiber-optic 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-Fnetwork connection, RPT-F, RPT-WF.

In some networks, it may be necessary to mix twisted-pair wire and fiber-optic cable. There are two solutions:

• In any network, an RPT-WF may be used as an interface between wire and fiber.

In a network that uses an AFP1010 or AM2020, a MIB-WF may be used as the interface between wire and fiber.

Both NCM-W and NCM-F can be installed in any standard chassis such as the CHS-4L, CHS-M2, CHS-M3 or CHS-4N (see panel sheets). Additionally, the NCM-W can be door-mounted on the ADP-4B dress panel on a single-space blank plate (BMP-1) for mounting in an CAB-4 Series cabinet.
