14 AFP-3030 Installation Manual — P/N DOC-01-031:F 19/11/2018Installation Connecting the Network Communications Module5. For the top (second) layer of option boards, slide the tab at the bottom of the board into the slots on the chassis, and lay the boardback onto the top of the chassis so that the studs line up with mounting holes on the option board. Securely fasten all stand-offs withscrews provided with module.Mounting procedures: Door mountIf mounting the option board in the door behind a blank dress plate, see Figure 3.2. This dress plate is suitable for option boards, whichdo not need to be visible or accessible when the door is closed.3.4 Connecting the Network Communications ModuleIf networking two or more control panels (or network control annunciators), each one requires a Network Communications Module; awire version and a fibre version are available. The wire and fibre versions on the NCM or HS-NCM can be installed on the CPU andpower supply assembly. The preferred position is on top of the CPU assembly, as shown in Figure 3.3.1. Mount the NCM or HS-NCM in the selected position. (See Figure 3.3)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 twoNCMs 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.NOTE: Mounting two pairs of loop-control and -expander modules in one chassis position may cause intermittent electricalinterference. If this occurs, move one pair to a separate chassis position.Fasten option boardto the plate with fourscrews (included).OptionBoard-Door.wmf, OptionBoardInstalled-Mount option boardonto stand-offs(included) to the blankplateMount single-space blankplate onto the door.Figure 3.2 Door-Mounting Option Boards with a Single-space Blank PlateNOTE: See the Noti•Fire•Net Version 5.0 & Higher Manual and the NCM Installation Document or the High-SpeedNoti•Fire•Net Manual for system configuration information.NOTE: Over-bending fibre-optic cable can damage it.
