Sensor Installation Instructions
❶Select the mounting location.
Mounting Location Guidelines
•2.3 m mounting height
•Avoid direct or reflected sunlight
•Aim sensor away from windows or heating/cooling devices
•Sensor must have a clear
❷Separate the sensor housings and remove the printed circuit board (PCB).
Note: The cover screw, when used, is installed here.
•Use a small screwdriver to unfasten the housing latch. Gently pull apart the housings.
•Push outward on the PCB latch and lift the PCB out of the housing.
❸Mount the unit.

❹Wire the unit.
•Connect wires as shown using 0.2 - 1.3 mm2 wire size. Observe proper polarity.
•If not using the integrated EOL resistors, remove jumpers from all pins.
•If using the integrated EOL resistors:
1.Connect the sensor to the panel (see one and two loop wiring diagrams on the right).
2.Place the jumpers on the appropriate tamper and alarm pin options (see table below).
Notes:
•Consult the Control Panel manual to determine proper EOL selection.
•Fit only one jumper each for the tamper and alarm EOL settings.

•Apply power to the unit. Initialization is complete when the LED stops flashing slowly.
•Adjust the microwave range to minimum setting (25%) by turning the range adjustment counterclockwise using a small screwdriver.
•Replace the front housing.
•Begin walking through the detection area.
- The LED will turn red, indicating an alarm detection.
•Increase the microwave range as necessary.
•Repeat the items in step 5a until proper detection range is obtained.
❺b Optional: Walk-test using Zone Finder.
Use the Zone Finder mode to identify the PIR and/or microwave pattern. In Zone Finder mode the red LED is disabled.
•Use a screwdriver to short the test pads.
•During the Zone Finder
-green for one second for every PIR detection;
-yellow for two seconds for every microwave detection.
•Adjust the microwave range as necessary.
•Zone finder mode times out after ten minutes.
