Troubleshooting
Motion Detector activates Chime at night as well as during the day...
• The ambient level of light at the motion detector may be too high for the current dusk setting
permanently simulating day-time. At dusk, adjust the dusk control slightly clockwise. Move
around the detection area to see if the movement still activates the Chime. If necessary
continue to adjust the dusk setting until movement does not activate the Chime. In extreme
cases it may be necessary to reposition the detector.
• The motion detector may be illuminated by a light at night preventing the ambient light level
falling low enough for the current dusk setting. Try adjusting the dusk setting or shielding the
detector from the light. In extreme case it may be necessary to reposition the detector.
Motion Detector does not activate Switching Receiver and lights at all...
• Check that the battery in the detector is not exhausted.
• Check that the power to the Receiver is switched ON.
• Check the bulb and replace if defective. Ensure that the light bulb is correctly fitted.
• Turn OFF the power to the unit and check the wiring connections as per the wiring diagram.
Ensure all connections are correct and terminals are tight. Check the connections at the
switch, detector and Light.
• Check that the fuse or circuit breaker supplying the lighting circuit has not blown or tripped.
Before replacing the fuse or resetting the circuit breaker be sure to check for the cause.
