PIR33
Instructions
Congratulations on purchasing the PIR33 infrared motion sensor!
The PIR33 adopts a sensitivity detector and integrated circuit. It gathers automatism, conveniently and
safely saving energy with practical functions. Is designed to automatically turn lights on when motion and
body heat is detected. It utilizes the infrared energy from humans as a control-signal source; it can start the
load at once when one enters the detection field. It can identify between day and night, easy to install and
has a wide variety of uses.
SPECIFICATIONS:
Power Source: 220-240V/AC Detection Range: 360°
Power Frequency: 50Hz Detection Distance: 6m max(<24℃)
Time Delay: Min.10sec±3sec Ambient Light: <3-2000LUX (adjustable)
Max.15min±2min Working Temperature: -20~+40℃
Rated Load: Max. 1200W Working Humidity: <93%RH
300W Power Consumption: approx 0.5W
Installation Height: 2.2-4m Detection Moving Speed: 0.6-1.5m/s
FUNCTIONS:
Can identify day and night automatically:The user can adjust the ambient light according to his/her
requirements. It can work in the daytime and at night when it is adjusted on the “sun” position (max). It
can work in the ambient light less than 3LUX when it is adjusted on the “3” position (min). As for the
adjustment pattern, please refer to the testing pattern.
Time-Delay is added continually: When it receives the second induction signal within the first
induction, it will add the time from the second setting.
Good sensitivity Poor sensitivity
INSTALLATION ADVICE:
As the detector responds to changes in the temperature, avoid the following situations:
Avoid pointing the detector towards objects with highly reflective surfaces, such as mirrors etc.
Avoid mounting the detector near heat sources, such as heating vents, air conditioning units, light etc.
Avoid pointing the detector towards objects that may move in the wind, such as curtains, tall plants etc.

CONNECTION:
Warning. Danger of death through electric shock!
Must be installed by professional electrician.
Disconnect power source.
Cover or shied any adjacent live components.
Ensure device cannot be switched on.
Check power supply is disconnected.
Unload the transparent vinyl cover which is at the bottom of the sensor.
Loosen the screws in the connection terminal, and then connect the power to connection terminal of
sensor according to connection-wire diagram.
Install back the transparent vinyl cover into the original location.
Fold the metal spring of the sensor upwards, until they are in “I” position with sensor, and then put the
sensor into the hole or installation box which is on the ceiling and has the similar size with the sensor.
Releasing the spring, the sensor will be set in this installation position.
After finishing installing, turn on the power and then test it.

CONNECTION-WIRE DIAGRAM:
(See the right figure)
TEST:
Turn the TIME knob anti-clockwise
on minimum, turn the LUX knob
clockwise on the maximum (sun).
Switch on the power; the sensor
and its connected lamp will have no signal at the beginning. After Warm-up 30sec, the sensor will start
working .If the sensor receives the induction signal, the lamp will turn on. If there is notanother
induction signal, the load will stop working within 10sec±3sec and the lamp will turn off.
Turn LUX knob anti-clockwise on the minimum (moon). If the ambient light is more than 3LUX, the
sensor will not work and the lamp will stop working. If you cover the detection window with the opaque
objects (towel etc), the sensor will still work . If there is no induction signal, the sensor should stop
working within 10sec±3sec.
Note: When testing in daylight, please turn LUX knob to (SUN) position, otherwise the sensor
lamp will not work! If the lamp is more than 60W, the distance between the lamp and sensor should
be at least 60cmt.
PROBLEMS AND SOLUTIONS:
The load does not work:
a. Please check if the connection-wiring of power and load is correct.
b. Please check if the load is good.
c. Please check if the working light sets correspond to ambient light.
The sensitivity is poor:
a. Please check if there is any hindrance in front of the detection window that affects the
receiving signal.
b. Please check if the ambient temperature is too high.
c. Please check if the induction signal source is in the detection fields.
d. Please check if the installation height corresponds to the height showed in the instruction.
e. Please check if the moving orientation is correct.
The sensor cannot shut off the load automatically:
a. Please check if there is continual signal in the detection field.
b. Please check if the time delay is the longest.
c. Please check if the power corresponds to the instruction.
