3.5.3 Loop Expander
Module
Installing a Loop Expander Module adds a
second SLC loop to the control panel. Refer
to the Figure 10 for connector illustrations.
1. Thread four (4) 0.937 inch (23.8 mm)
stand-offs through indicated holes in the
CPU-640 board.
2. Plug stacker-connector into J3 on the
CPU-640.
3. Lay the LEM onto the standoffs and
connect the Loop Expander Module
(LEM) into the stacker-connector
attached to J3.
4. Attach LEM using screws provided with
the module.
5. After LEM is mounted on the control
panel, connect the SLC loops to TB1 on
the LEM and TB16 on the CPU-640.
This system supports either FlashScan or CLIP mode devices. Refer to the SLC loop manual
for wiring requirements and specific details.

The long-pin end
plugs into the back
of the LEM board.
The short-pin end plugs
directly into the top of the
CPU-640 plug.
!
CAUTION: If the stacker-connector is installed incorrectly, the short-pin end of the plug can
to make a secure connection when plugged through the back of the LEM.
