PIR Occupancy Sensor Switch
(Neutral Required)
Model #：BRT-304C
Features:
BRT-304C is an occupancy sensor switch which utilizes passive infrared (PIR) sensor to detect the
heat (in the form of infrared energy) from people moving within a space. It can determine when a
space is occupied and turns on or turns off the loads automatically. It is designed for easy
installation and retrofit, directly fit into standard wall box where both “hot” wire and neutral wire
are present.
Load power up to 800W;
Adjustable delay-off time from 10 seconds to 15 minutes;
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.

Wiring Diagram and Installation Guide:
BRT-304C 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.

Fig. 4 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.

a. Counter-clockwise to “+”: increase the threshold, so that the PIR triggers will be
overridden in bright lighting condition; and
b. Clockwise to “-”: decrease the threshold, so that the PIR triggers will not be overridden
in dark lighting condition.

2. Adjust the delay-off time
There is another tuning screw on another side of BRT-315 PIR sensor switch. Use a screw driver
to tune this screw to adjust the delay-off time, as shown in Fig. 7. The delay-off time can be set
from 10s to 15 minutes.
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.
