Motion Sensor Installation Instructions
TT
Step 1
Separate the sensor housings and remove
Printed Circuit Board (PCB).
Use a small screwdriver to unfasten the hous-
ing latch and separate the sensor housings.
Push outward on the PCB latch to lift the PCB
out of the housing.
Step 3
Wire the sensor.
Observing the proper polarity, wire the unit as
shown in the illustration below, use 1.02 to 0.64 mm
(18 to 22 AWG) wire.
Step 2
Mount the sensor.
Break out the mounting/wiring knockouts and
mount the sensor in an appropriate location.
An ideal location meets the following objectives:
• Allows a clear line-of-sight to all areas to
protect.
• Does not directly face windows.
• Avoids close proximity to moving machinery,
fluorescent lights, and heating/cooling
sources.
NOTE: maximum range is obtained at a
mounting height of 2.3 m (76).

Walk-test the sensor.
After returning the PCB to the rear housing,
reassemble the sensor housing. Apply
power to the sensor and begin walk-test
when the red LED is off.
Walk across the detection area at the ranges
to be covered. The red LED should indicate
an alarm condition after 2 to 4 normal steps.
When there is no motion in the detection
area the LED should be off.

Summary

Sensor Installation and Testing

Separate Sensor Housings and PCB

Unfasten housing latch, separate housings, and lift PCB from housing using the latch.

Mount the Sensor

Break out knockouts, mount sensor in an ideal location for clear line-of-sight and optimal coverage.

Wire the Sensor

Wire the unit observing polarity, using 1.02 to 0.64 mm (18 to 22 AWG) wire.

Walk-test the Sensor

After reassembly, apply power and walk-test. LED should indicate alarm after 2-4 steps when motion is detected.
