Notifier NCM-W

NCM Installation PN 51533:A1 03/27/03
1 Product Overview
The Network Communications Module (NCM) provides a means for connecting specific Notifier fire
alarm control products to NOTI•FIRE•NET™. There are two types of NCMs available: NCM-W for
connecting nodes with twisted-pair wire, and NCM-F for connecting nodes with fiber-optic cable.
1.1 The Network Communications Module for Wire (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™.
• Refer to the
NOTI•FIRE•NET™ Manual (Network
Version 4.0 and Higher) for wiring length and threshold
information.
1.2 The Network Communications Module for Fiber (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, 8 dB limit)
• 50/125 micrometers (multimode, 4.2 dB limit)
• Wavelength (1): 820 nanometers. (Use standard 850 nm
fiber.)
• Connectors: ST® Style (ST® is a registered trademark of
AT&T).
• 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™.
