Notifier HS-NCM: High-Speed Network Communications Modules

The High-Speed Network Communications Module (HS-NCM) provides NOTIFIER’s NFS-320, NFS-640, NFS2-640, NFS-3030, and NFS2-3030 Fire Alarm Control Panels, NCA and NCA-2 Network Control Annunciators, and DVC Digital Voice Command with a means to connect to High-Speed NOTI.FIRE.NET (NFN).

Each HS-NCM can accommodate up to two node addresses. For example, one HS-NCM can provide network communication for both an NFS2-640 and an NCA-2.

When not connected to a fire alarm panel, the HS-NCM defaults to repeater mode and can be used to boost signal distances or to pass data transmissions between two differently configured network segments when wire and fiber co-exist on a network.

Features

• 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
• High-Speed NFN fiber-optic medium
• Fiber type: 62.5/125 micrometers (multi-mode); 50/125 micrometers (multimode), or 9/125 micrometers (single mode)
• Maximum attenuation: 10 dB with 62.5/125 μm cable, 6.5 dB with 50/125 μm cable, and 30 dB with 9/125 μm cable

• Two network ports to allow simultaneous connection to fire alarm control panel and to programming computer
• Enables software and database upload/download over the High-Speed NFN

HS-NCM-MF/SF 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 connects to Port B of another node/repeater. A HS-NCM-MF/SF may be connected to any of the following devices:

• HS-NCM-MF/SF (respectively) on another panel
• HS-NCM-WMF-2
• HS-NCM-WSF-2
• HS-NCM-MFS
