The easiest way to install a motion detector is to replace an existing light with the detector. If you are uncomfortable working with electricity you should call a professional to install your motion detector.

• Be sure when working with electricity that you have the power turned off. Working with electricity is serious business and not to be taken lightly. Turn the power off at the main fuse or breaker box.
• Test the wires to be sure the power is off.
• Place tape over the switch to alert others that the switch should not be turned on.
• Outside motion detectors should be mounted to weatherproof covers on weatherproof boxes.
• When attaching the motion detector to a wall, attach it at a height of five to six feet. Use the mounting bracket and screws that are provided.
• The detector should be mounted to face outwards horizontally so that the lens is facing downwards.
• Direct sunlight should not fall on the lens of the motion detector.
• The detector should not face any reflective surfaces such as large windows or swimming pools.
• Do not mount above heating vents or air conditioning units.

Normally, the control adjustments will be found under the cover on the underside of the detector.

• Use a small screwdriver when making adjustments. Do not force the adjustment screws.
• Reduce the sensor sensitivity 1/8 turn at a time.
• Use black electrical tape when blocking off any lens areas where unwanted light is being detected.

There is normally a slide switch on the bottom of the motion detector used for testing the detector.

• Turn the power on at the switch or breaker box.
• Move the switch to the test position.
• Walk around within the sensing area to be sure the lights come on.
• Walk around outside of the sensing area watching to be sure the lights do not activate.
