Keypad Wiring
When you are placing both a keypad and a sensor (or two keypads)
in one room you may “daisy-chain” using a single cable. A cable is
run between the keypad and the sensor and a single cable is run from
either the sensor or the keypad back to the IRP2+. See
Figure 5
.
Sensor/Keypad Cable
The IRP2+ connects to IR sensors and keypads with 2-conductor shield-
ed cable. Recommended cables are “data grade” cables made of two
22 gauge (or larger) conductors surrounded by a foil shield and a bare
drain (ground) wire. Data grade cable provides the capability for runs
of up to 500 feet to each sensor. Examples are West Penn D291,
Belden 8761 or Carol C 2516. Any 22 to 16 gauge 2-conductor shield-
ed cable available at a hardware store will accommodate 150 foot runs
to each sensor.
Flasher Cable
Niles infrared flashers come supplied with a 10 foot 2-conductor 22
gauge cable. Should you need to extend it, use a 16 gauge 2-conduc-
tor cable (“zip-cord”). Shielding is not necessary for a flasher. Flasher
wires can be extended up to 200 feet.

CAUTION!
Do not use un-
shielded cable
between any
remote IR sensor
or keypad and the
IRP2+.
