Connecting Specific Option Boards

3.14 Connecting Specific Option Boards
3.14.1 Network Control Module
If networking two or more control panels (including JNCAs ), each one requires a Network Control
Module; a wire version and a fiber version are available. The NCM-W/F can be installed in any
panel circuit module position (see Section 3.7 "Attaching Panel Circuit Modules"); the default
position is immediately to the right of the main circuit board.
1. Mount the 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 using the network cable provided (P/N 75556). Do
not connect two NCMs via NUP ports (aka NUP to NUP).
3. Connect Channel A and/or Channel B as described in the NCM Installation Document.
NOTE: See the Noti•Fire•Net Version 4.0 & Higher Manual and NCM Installation Document 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.
3.14.2 Loop Control Module, Loop Expander Module

Mounting Instructions

Mount loop control and expander modules within the cabinet with the CPU. Standard mounting
positions are adjacent to the panel or in the row immediately below it. Follow the basic
chassis-mounting instructions given for option boards; LEM-320 modules are mounted first;
LCM-320 modules are mounted on top of those. Alternately, LCM-320 and LEM-320 modules can
be attached to each other and mounted as a pair to the chassis. See Figure 3.20 for 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 3.7.3 "Installing a Multi-layer Module into the
Chassis". If using LCM-320/LEM-320 in CHS-4L see Figure 3.21.
NOTE: Mounting two pairs of LCM-320 and LEM-320 modules in one chassis position may
cause intermittent electrical interference. If this occurs, move one pair to a separate chassis
position.
After all loop control and expander modules are mounted in the cabinet, connect the SLC loops to
TB1 on each loop control and expander module as shown in Figure 3.22. Daisy-chain the loop
control modules as shown in Figure 3.23. The ribbon-cable connection runs from header J7 on the
CPU to header J1 ("Data in") on the first loop control module, from J3 ("Data out") on that unit to
J1 on the next unit in the chain, and likewise for up to five loop control modules. Each module
should be assigned a unique SLC loop number (see below); loop number does not need to match
the module's locaiton in this daisy-chain.
FlashScan devices can operate in either FlashScan or, for retrofit applications, CLIP mode. Each
LCM-320 or LEM-320 running a FlashScan SLC can support up to 159 detectors and 159 modules.
CLIP loops are limited to 99 detectors and 99 modules. Older models of CLIP devices only
support addresses up to address 99. These and other capacity restrictions for CLIP mode loops are
discussed in Section 3.19 "Wiring a Signaling Line Circuit (SLC)". Refer to the Johnson Controls
SLC Wiring Manual for wiring requirements and specific details.
