===== Installation instruction =====

  * Do not install the detector at position which faces direct or reflected sunlight or near windows with direct car headlight.

  * Ensure that there are no obstructions (plants, screens, furniture etc.) in the field of view that may cause incorrect cover/operation of the detector.

  * Avoid locating the detector in areas that contain equipment that may change the environment temperature rapidly (i.e. above radiator or under the air-conditioner)

  * Install the detector at proper height on a rigid surface. Do not install the detector on vibrating surface.

  * PIR detector is more sensitive to the motions “across” the detection zones than “toward” or “away”.
