3.6.6 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 of each are available. The wire and/or fiber versions of the
NCM or the HS-NCM can be installed in any standard option-board position (see Section 3.6
"Mounting 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 in place firmly.
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 (aka 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
NOTE: See the Noti•Fire•Net Manual or the High-Speed Noti•Fire•Net Manual and NCM
Installation Document or 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.
