PIR1
Instruction
Welcome to use SSEN/CR/ST/WH infrared motion sensor!
This ceiling recessed PIR sensor utilizes a good sensitivity detector and integrated circuit for
energy-saving, safety and practical functionality. It utilizes infrared technology to detect movement
of the human body and will switch on the load once someone enters the detection field. It has an
inbuilt photocell to detect between day and nighttime operation.
SPECIFICATION:
Power Source: 220-240V/AC Detection Range: 360°
Power Frequency: 50/60Hz 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
FUNCTION:
➢Can identify day and night: The installer can adjust the switching point at different ambient
light levels. It can operate in both day and night when the dial is set to the “sun” position
(max). It can work at night only when the dial is set towards the “3” position (min). As for the
adjustment pattern, please refer to the testing pattern.
➢Time-Delay is extended continually: During periods of continued occupancy, the sensor will
restart the time delay with each detection of movement.
Good sensitivity Poor sensitivity
INSTALLATION ADVICE:
As the detector responds to changes in 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,
lights etc.
➢Avoid pointing the detector towards objects that may move in the wind, such as curtains, tall
plants etc.

CONNECTION:
⚫Must be installed by a competent person.
⚫Disconnect power source.
⚫Cover or shied any adjacent live components.
⚫Ensure device cannot be switched on.
⚫Check power supply is disconnected.
➢Remove the transparent vinyl cover on the top of the sensor.
➢Loosen the screws in the terminal, and then connect the power to terminal according to wiring
diagram.
➢Install the transparent vinyl cover back onto the sensor.
➢Fold the metal spring of the sensor upwards, until they are in “I”position with sensor, and
then place the sensor into the hole in the ceiling. Release the spring to fix the sensor into
position.
➢Turn on the power and then test the sensor functionality.

SENSOR INFORMATION:
TEST:
➢Turn the TIME knob anti-clockwise to the minimum
(10s). Turn the LUX knob clockwise to the maximum
(sun).
➢Switch on the power; the sensor and its connected
lamp will have no signal at the beginning. After a
30sec warm-up period, the sensor will be operational. If the sensor detects movement, the
load will turn on. When no further movement is detected, the load should switch off within
10sec±3sec.
➢Turn LUX knob anti-clockwise to the minimum (3). If the ambient light is more than 3LUX,
the sensor will switch the load off. If the ambient light is less than 3LUX (darkness), the
sensor will switch on the load. With no occupancy detected, the sensor will stop working
within 10sec±3sec.
Note: when testing in daylight, please turn LUX knob to (SUN) position, otherwise the
sensor may not work!
TROUBLESHOOTING:
➢The load does not switch on:
a. Check the power and the load.
b. Please check if the load is operational.
c. Please check the light level setting.
➢The sensitivity is poor:
a. Please check if the sensor is obstructed from detecting movement.
b. Please check if the ambient temperature is too high.
c. Please check if the movement is in the detection field.
d. Please check if the installation height corresponds to the height required in the
instruction.
➢The sensor does not shut off the load automatically:
a. Please check if there is continual movement in the detection field.
b. Please check if the time delay is set to the maximum duration
c. Please check if the wiring corresponds to the instruction.
Height of installation: 2.2-4m
Detection Distance: Max.6m
