Installation
Connecting the Power Cables
Network Communications Module
If networking two or more control panels or network control annunciators, each unit requires a
Network Communications Module (NCM) or a High-Speed Network Communications Module
(HS-NCM); wire and fiber versions are available for each. The wire and/or fiber versions of the
NCM or HS-NCM can be installed in any standard option-board position (see Section 3.4,
“Installing Option Boards”; the default position is immediately to the right of the control panel.
1. Mount the NCM/HS-NCM in the selected position and screw firmly in place.
2. Connect J1 on the control panel to J3 on the NCM or J6 of the HS-NCM using the network
cable provided (P/N 75556) as described in the
NCM Installation Document
and the
HS-NCM
Installation Document
. Do not connect two NCM/HS-NCMs via NUP ports (“NUP to NUP”).
3.
When installing the NCM
: Connect Channel A and/or Channel B as described in the
NCM
Installation Document
.
When installing the HS-NCM
: Connect Channel A to Channel B as described in the
HS-
NCM Installation Document
.
3.5 Connecting the Power Cables
3.5.1 Overview
Complete all mounting procedures and check all wiring before applying power. Electrical
connections include the following:
•
Primary AC power source – 120 VAC, 50/60 Hz, 5.0 A from line voltage source (with NFS-
320E use 220-240 VAC, 50/60 Hz, 2.5 A). Overcurrent protection for this circuit must comply
with Article 760 of the National Electrical Code (NEC) and/or local codes. Use 12 AWG (3.31
mm
2
) wire (maximum) with a 600-volt rating.
•
Secondary power source – 24 VDC from batteries, installed in the control panel (or in an
optional battery cabinet). Secondary (battery) power is required to support the system during
loss of primary power.
NOTE:
See the
Noti•Fire•Net Manual
or the
High-Speed XLS-NET Manual
and
NCM Installation
Document
or the
HS-NCM Installation Document
for wiring diagrams and system configuration
information. See the
BMP-1 Product Installation Drawing
if considering mounting the module
behind blank module plate in a dress plate or annunciator backbox.
NOTE:
Over-bending fiber-optic cable can damage it. Do not exceed a 3 inch (7.62 cm)
minimum bend radius.
NOTE:
NCM hardware is not compatible with HS-NCM hardware and should not be mixed on
the same network.
!
WARNING:
Remove all power sources to equipment while connecting electrical components. Leave the
external, main power breaker OFF until installation of the entire system is complete.
!
WARNING:
Several sources of power can be connected to the control panel. Before servicing the control panel,
disconnect all sources of input power
including the battery
. While energized, the control panel and
associated equipment can be damaged by removing and/or inserting cards, modules, or
interconnecting cables.
