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 C2516. 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+.
