HS-NCM-MF (Nordiphel/Honeywell) high-speed network communication card
HS-NCM-MF is a NOTIFIER high-speed NFN (NOTE, FIRE, NET) fiber optic network card used for multi-mode fiber optic networking of fire protection hosts such as NFS2-3030/NFS-3030, achieving high-speed networking and centralized management of multiple hosts.

1、 Model positioning (6 options available)
HS-NCM-MF: multimode fiber (62.5/125, 50/125 μ m), LC interface
HS-NCM-SF: Single mode fiber (9/125 μ m)
HS-NCM-MFSF: Multi mode+Single mode Hybrid
HS-NCM-W-2: Twisted Pair (12 Mbps)
HS-NCM-WMF-2: twisted pair+multimode
HS-NCM-WSF-2: twisted pair+single-mode
2、 Core parameters (MF version)
1) Physics and Interface
Speed: 100 Mbps (fiber optic)
Fiber optic: multimode 62.5/125 μ m (most commonly used), 50/125 μ m
Connector: LC duplex (TX/RX)
Wavelength: 1310 nm
Maximum attenuation: 62.5/125:10 dB; 50/125:6.5 dB
Distance: about 2 km for multimode (apparent attenuation)
Node count: Up to 2 network addresses per card
2) Network and Protocol
Network: High speed NFN (Noti, FIRE, NET)
Topology: daisy chain, star shaped, ring network (Class A redundancy)
Redundancy: Supports NFPA Style 7 (Class A redundancy)/Style 4 (Class B)
Isolation: photoelectric isolation, eliminating ground loop interference, anti EMI/RFI
3) Compatibility
Compatible hosts: NFS2-3030, NFS 3030, NFS 640, NFS 320
Compatible peripherals: NCA/NCA-2 network display, DVC voice host
4) Electrical and Environmental
Power supply: Host backplane 24 VDC, approximately 150 mA
Temperature: 0 ℃~+49 ℃
Humidity: ≤ 85% (no condensation)
3、 Key functions
High speed networking: 100 Mbps fiber optic, multi host networking (up to dozens of devices)
Data regeneration: signal restructuring at each node to extend transmission distance
Redundant fault-tolerant: dual fiber paths, automatic switching for single segment faults
Remote programming: network uploading/downloading programs, databases, firmware upgrades
Status monitoring: The host can recognize the status of network cards, link failures, and communication quality
4、 Typical application (NFS2-3030 system)
Large scale park/commercial complex: Multiple buildings with fiber optic networking and unified monitoring by the fire control center
High interference environment: factories, substations, fiber optic anti-interference is better than twisted pair cables
Long distance transmission: Building spacing>500 meters, stable and reliable multi-mode fiber optic
5、 Difference from HS-NCM-SF
MF (multimode): cheap, short distance (≤ 2 km), commonly used in computer rooms/parks
SF (Single Mode): Used for expensive, long-distance (≤ 20 km), cross city/long-distance projects
