Notifier NCM-F ONYX Network Communications Module, Multimode Fiber, ST Connectors

Notifier NCM-F — ONYX Series Network Communications Module attaching one node to NOTI-FIRE-NET over multimode fiber-optic cable.

It is the network interface of the node it sits in, not a link between two classes of equipment. Notifier gives the NCM to intelligent fire alarm control panels and to NCA and NCA-2 network control annunciators alike, each carrying its own module on this peer network.

• Multimode fiber only, 62.5/125 µm or 50/125 µm, ST style connectors, 820 nm wavelength
• Maximum attenuation 8 dB on 62.5/125 µm and 4.2 dB on 50/125 µm
• NFPA Style 4 (Class B) or Style 7 (Class A) at 312.5 Kbaud, optically isolated
• Two ports let the panel and a programming computer connect at once
• Fiber leaves one board on TX and enters the next on RX; pairs with MIB-F, NAM-232F, RPT-F or RPT-WF
• 24 VDC at 110 mA, UL and ULC certified under S635, FM and MEA approved
• Mounts in a CHS-4L, CHS-M2, CHS-M3 or CHS-4N chassis

The NCM-W is the twisted-pair version, reaching up to 3,000 ft. between nodes, and an RPT-WF repeater bridges wire and fiber. Notifier warns against mixing NCM and High Speed NCM boards.

FAQ

What fiber does the NCM-F use?
Multimode fiber, 62.5/125 µm or 50/125 µm, with ST style connectors at 820 nm.

How much fiber loss is allowed?
Maximum attenuation is 8 dB with 62.5/125 µm fiber and 4.2 dB with 50/125 µm fiber.

Can it be mixed with High Speed NCMs?
No. Notifier says not to mix NCM and High Speed (HS) NCM on the same system.

Is there a wired version?
Yes. The NCM-W connects nodes with twisted-pair wire.
