BRT-304C Installation Guide
Cautions:
1.
Avoid mounting the sensor switch close to air vents, as the vibration and air flow can reduce
the effectiveness of the sensor switch;
2.
Avoid installing the sensor switch in an electrical circuit which has other frequent on/off
switch or appliance, as those on/off actions could cause false triggers.
BRT-304C Operation Guide:
BRT-304C PIR sensor switch needs a warm-up time about two minutes before it can operate
properly. It has a precision tuning screw to adjust the ambient light override threshold as shown in
Fib. 5, and another precision tuning screw to adjust the delay off time as shown in Fib. 6.
1.
Adjust the ambient light override threshold
Please refer to Fig. 5. The fine tuning screw is used to set the ambient light override threshold. Use
a screw driver to tune the screw gently.
Caution:
The tuning screw can not make a full turn. To avoid possible damage to the screw,
please do not use strong force to tune it.
