Niles CS120 Installation & Operation Manual page 4

To avoid optical feedback:
1. Re-position the f1asher(s) and/or the sensor
2. Use Niles an MF1 or MF2 Microflasher and cover
them with the supplied IR blockers
Using the CS120 with the Niles Multilane
keypads with an IR connection
The CS120 is fully compatible with Niles MultiZone
keypads with an IR connection, follow the wiring
instructions in
Figure 5.
For specific information
see your Niles MultiZone keypad manual.
INSTALLATION
If you are installing the CS120 into an existing
ceiling, take time to consider any possible obstruc-
tions which may be hidden, such as wood or metal
studs, electrical, telephone or other types of wiring,
plumbing, AC or heating conduits, etc.
1. Determine a mounting location for the CS120
2. Drill a 11/16" hole where the CS120 will be
mounted
3. Run the CS120's IR cable. Label the cable for
future reference
(Figure 2).
The CS120 is sup-
plied with 10' ofpre-stripped IR cable. The IR ca-
ble may be shortened or lengthened as needed.
If you want to make the CS120's cable shorter,
use a pair of wire cutters to cut the cable to the
desired length. The IR cable may be lengthened
5
by splicing it to a recommended IR cable (See
Installation Considerations-Type of Cable). You
may splice the CS120 cable to another cable by
soldering or crimping the connections.
4. Fasten sensor to ceiling with supplied screws
(Figure
3)
5. Connect the CS120 cable to the main system
unit
(Figure 1).
Strip 1/4" of insulation from the
end of each wire. Tightly twist the end of each
wire until there are no frayed ends. Insert each
wire into the appropriate hole on the removable
connector plug, and snap the locking tab down.
To help you, the connector plug is keyed. Insert the
smooth side of the connector plug into the smooth
side of the socket. Don't force the scalloped side
of the connector plug into the smooth side of the
socket. Refer to the main system main system unit
manual for specific installation instrutions.
