Network Control Module 300 Series Technical Bulletin 74

Appendix A: Fire-Net NCM

The Fire-Net Network Control Module (Fire-Net NCM) is a fire

network controller connected to the Metasys Intelligent Fire Network

(MIFN). It is an NCM300 that is listed under UL 864 UOJZ and meets

the requirements of National Fire Protection Association (NFPA) 72 as

part of a Local Protective Signaling System and/or a Proprietary

Protective Signaling System.

To comply with UL 864 UOJZ, the Fire-Net NCM communicates fire

alarm signals to a Proprietary Supervising Station, namely the Fire

Operator Workstation (Fire OWS). At least two operators, one of

whom is permitted to be a runner, must be in attendance at a Fire OWS

at all times to respond to those signals if the fire alarm system is

configured and operated as a Proprietary Protective Signaling System.

Optionally, an automatic alarm sent to the fire department can replace

one of the operators.

A Fire-Net NCM can communicate with up to a maximum of

10 IFC-1010/1020 panels. If more than 10 IFC panels are connected to

the Metasys Intelligent Fire Network, additional Fire-Net NCMs are

needed.

Note: UL 864 UOJZ requires that each qualified fire system have

established procedures for operators to follow in the event of a Fire

Alarm System Report.
