CONNECTING IR SENSORS
An IR sensor can be connected to a Solo
™
and
Select
™
Master Keypad Module in one of two
ways, directly with a four-pair twisted cable
(see Figure 34 and 35), or with a three-wire to
RJ-45 adapter available from Niles for IR sen-
sors installed with two-conductor shielded
cable. (See Figure 36 and the Accessories
Section of this manual.)
Connecting a Sensor Using Four-Pair
Twisted Cable
In Figure 34, one end of the four-pair twisted
cable connects with bare wire to the IR sensor.
The other end terminates with a male RJ-45
connector and plugs into the Solo
™
and
Select
™
Master Keypad Module.
Figure 34 depicts the correct wires to use for connection to the IR sensor when using four-pair twisted cable
terminated with an RJ-45 connecter at the Solo
™
and Select
™
Master Keypad Module.
Connecting a Sensor Installed with Two-Conductor Shielded Cable
An IR sensor installed with two-conductor shielded cable requires the Niles three wire to RJ-45 adapter (see
Accessories) for proper connection to a Solo
™
and Select
™
Master Keypad Module (see Figure 36). The IR sen-
sor connects to the two-conductor shielded cable with bare-wire, screwdown terminals. (Refer to the IR sen-
sors Installation Guide for more information.) The two-conductor shielded cable then connects to the adapter’s
bare-wire, screwdown terminal, matching 12V, GND, and Data respectively.
