Wiring
From every IR Sensor location you must “home-run” a cable back to
the IRP2+. Home run means that an individual cable is connected
between each IR Sensor and the IRP2+. See
Figure 4

TECH TIP
Wire size is
expressed by it's
AWG (American
Wire Gauge)
number. The lower
the AWG number,
the larger the wire,
i.e., 20 AWG wire is
physically larger than
22 AWG.
Figure 4: Home run the sensor cable from each sensor to the IRP2+.
IMPORTANT – AVOIDING INTERFERENCE
Avoid locating any of the cables, Sensors, Keypads or the
Main System Unit near any potential sources of Electro-
Magnetic Interference (EMI), such as light dimmers, speed
controls for ceiling fans, electrical ballasts, television sets,
large motors, heaters or air conditioners.
