Load power up to 2000W;
Adjustable delay-off time from 2 minutes to 60minutes (8 settings available);
Ambient light override. Automatically measures the ambient light level and there is no trigger on above a light level adjustable by users;
Good for all kinds of loads;
ABS-V0 flame resistance material; and
Classical 86 series design and high quality build.
Fig. 1 and Fig. 2 show the front view and the back view of the BRT-302C PIR occupancy sensor switch respectively.
BRT-302C occupancy sensor switch require both hot wire and neutral wire for installation:
Hot wire (ACL): Coming from the power line with 220V;
Neutral wire (ACN): Usually coming with the hot wire; and
Load wires: Going to the load.
Warning: Please make sure power is turned off before starting installation!
Fig. 3 shows the wiring diagram and Fig. 4 shows the step-by-step installation instructions. There are three easy steps:
Step one: Use a screwdriver to pry off the front plate in position A;
Step two: Wiring according to the diagram and the labelled ports of the switch; and
Step three: Install screws and front plate.
Warnings:
1. Please make sure power is turned off before starting installation!
2. Load shorting or using a load with a power rating higher than the specified wattage of the
sensor switch is prohibited.
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-302C 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. It also has dip switches to adjust the delay off time as shown in Fib. 2.
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.
a. Counter-clockwise to “+”: increase the threshold so that the PIR triggers will be overridden in bright lighting condition; and
2. Adjust the delay off time
BRT-302C PIR occupancy sensor switch has very high power rating. It can be used for automatically turning on and/or turning off various loads such as lights fans appliances or other kinds of electrical equipment especially good for high power loads.
BRT-302C PIR occupancy sensor switch is perfect for saving energy and bringing convenience and safety to our daily life and work. It has wide applications at various locations such as stairwells corridors washrooms offices conference rooms in homes schools laboratories hospitals offices etc.
