3.14 Connecting Specific Option Boards
3.14.1 Network Control Module
If networking two or more CPU units, 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).
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 24 for connector locations and
stand-off lengths.
Note: To suspend a pair of modules in the third and fourth layer, 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 25.
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 26. Daisy-chain the loop control modules
as shown in Figure 27. 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 capacity restrictions for CLIP mode loops are discussed in
Section 3.19 “Wiring a Signaling Line Circuit (SLC)”. Refer to the SLC Wiring Manual for wiring
requirements and specific details.
Setting SLC Loop Number. Assign a unique SLC loop number to an LCM-320 by setting SW1 on
the module to 1, 3, 5, 7, or 9. The LEM-320 which is mounted behind this LCM-320 will be assigned
the next-higher even number. For example, if the LCM-320 is set to loop number 5, the LEM-320
mounted to it will be set to loop number 6.
Enabling External Power Supervision. With LCM-320 revision 2.0 and higher, some type codes
have external power supervision built into the software; see Section 4.2 “Devices Requiring External
Power Supervision” for details.
