an existing panel’s or annunciator’s cabinet.

Use the Network Control Module PC board configuration that fits your installation needs.
• NCM-W with twisted pair wire.
• NCM-F with fiber-optic cable.

Step 2. After this installation is perform 

“NFN Gateway Power Connection” on page 23

.

When using an NCM-W/F, it can be powered by a panel/annunciators power source or the 
supplied NFN gateway’s power supply (

Figure 2.6

).

Refer to 

Table 2.1 on page 23

 for power supply specifications.

2 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.  

In most applications, one NCM is required per 

NOTI•FIRE•NET™

 node (including fire alarm control panels and 

network annunciators) .  Even though the NCM has two NUP ports, only one may be connected to a 

NOTI•FIRE•NET™

.

node.  Except in some DVC applications, do not connect two NCMs via NUP ports (aka “NUP to NUP”).  

For instructions on the additional capabilities available with the DVC, refer to the 

DVC Manual

.   

•

Input power requirements: 24 VDC , 0.11 amps, regulated, power-limited compatible power supply UL/ULC listed 
for fire protective signalling use.

•

Communications circuit requirements: Refer to the 

NOTI•FIRE•NET™

 Manual (Network Version 4.0 and Higher)

for wiring length and threshold information.

NOTE:

The NCM-W/F it can be powered by customer supplied external power supply, it should 

be UL listed for fire protective signaling systems, power limited and regulated.
