Motion Sensor Installation Instructions

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.
• See Special Instructions for installations
containing pets.
NOTE: maximum range is obtained at a mounting height of 2.3 m (7’6”).

Step 4 Walk-test the sensor. After returning the PCB to the rear hous- ing, reassemble the sensor housing. Ap- ply 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 nor- mal steps. When there is no motion in the detection area the LED should be off.
