Installation
Connecting the Network Communications Module
3.7 Connecting the Network Communications Module
If networking two or more control panels (or network control annunciators), each one requires a
Network Communications Module; a wire version and a fiber version are available. The wire and
fiber versions on the NCM or HS-NCM can be installed in any option board position described in
Section 3.6, “Attaching Option Boards”. The preferred positions are immediately to the right of the
main circuit board, or in the row below. If the system uses Digital Voice Command, the DVC’s wire
or fiber version of the NCM or HS-NCM can be mounted behind the DVC on its chassis; see the
DVC Manual for instructions. If using the Digital Audio Amplifier, the DAA’s wire or fiber version
of the NCM or HS-NCM can be mounted on the DAA chassis; see the DAA Manual for
instructions.
1.
Mount the NCM or HS-NCM in the selected position. If another board is going to be mounted
in the slot immediately in front of it, use stand-offs to secure it in place. Otherwise use the
screws provided.
2.
Connect J1 on the CPU to J3 on the NCM or J6 on the HS-NCM using the network cable
provided (P/N 75556). Do not connect two NCMs via NUP ports (aka NUP to NUP).
3.
When installing an NCM: Connect Channel A and/or Channel B as described in the NCM
Installation Document.
When installing a HS-NCM: Connect Channel A to Channel B as described in the HS-NCM
Installation Document.
3.8 Connecting the Loop Control and Expander Modules
3.8.1 Mounting Instructions
Mount loop control and expander modules within the cabinet with the CPU. Two typical mounting
positions are adjacent to the panel or in the row immediately below it. (DVC applications in the
CA-2 chassis have specific requirements; see 3.8.2, "Audio Applications with Chassis CA-2" at the
end of this section.) Follow the basic chassis-mounting instructions given for option boards. Loop-
expander modules are mounted first; Loop-control modules are mounted on top of those.
Alternately, loop-control and loop-expander modules can be attached to each other and mounted as
a pair to the chassis. See Figure 3.12 for connection instructions, connector locations and stand-off
lengths.
To suspend a pair of modules in the third and fourth layer of CHS-M3, follow the instructions given
in Section 3.8.5 “Installing a Multi-layer Module into the Chassis”. If using loop control and
expander modules in CHS-4L see Figure 3.14.
NOTE:
See the
Noti•Fire•Net Version 5.0 & Higher Manual
and the
NCM Installation Document
or the
High-Speed Noti•Fire•Net Manual
for system configuration information. See the
BMP-1
Product Installation Drawing
if considering mounting the module (wire version) 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.
NOTE:
Mounting two pairs of loop control and expander modules in one chassis position may
cause intermittent electrical interference. If this occurs, move one pair to a separate chassis
position.
