❶ Select the mounting location.
❹ Wire the unit.
❸ Mount the unit.
❺a Walk-test the sensor.
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 line-of-sight to protected area
• 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.
• Slide the wire through the wire channel and wire access in
the back housing.
• Mount the back housing flat against a wall or in a corner.
• Replace the PCB.
• 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 a screwdriver to short the test pads.
• During the Zone Finder walk-test mode, the LED turns:
- 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.

Jumper
Position EOL Value
• Connect wires as shown using 0.2 - 1.3 mm
2
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.
