If a door or window is closed, but the panel announces it is open:
• Be certain the arrow on the magnet and the guide line on the transmitter are
aligned and within ¼ inch of each other.
• The sensor tamper switch may be open (cover off).
If a motion sensor goes off continuously, be sure the sensor is mounted on a solid
surface and the viewing field is free from sources of changing temperature.
If a motion sensor does not respond to motion:
• Make sure the sensor battery is good and installed correctly. Wait 2 minutes after
installing a new battery to test the sensor.
• Adjust the sensor mounting.
• Leave the area for 3 minutes, then retest.
• The environment may be too hot or too cold. Outdoor sensors operate between
32 and 120ºF (0 and 49ºC).
• Dirt or dust may be causing the problem. Wipe the sensor with a clean, damp
cloth.
