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.
Mount the NCM/HS-NCM in the selected position and screw in place firmly.
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).
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: Over-bending fiber-optic cable can damage it. Do not exceed a 3 inch (7.62 cm) minimum bend radius.
ote: NCM hardware is not compatible with HS-NCM hardware and should not be mixed on the same network.
