Wall Mounted Hidden Infrared Motion Sensor Switch,220V Time Delay Adjustable LED PIR Sensor Light Switch  









  • Theory: The product is a new saving-energy switch; it adopts microwave sensor mould with high-frequency electro-magnetic wave(5.8GHz), integrated circuit.
  • Functions: It gathers automatism, convenience, safety, saving-energy and practicality functions. 
  • Performace: It utilizes the infrared energy from human as control-signal source, it can start the load at once when one enters detection field. It can identify day and night automatically.
  • Usage: Its installation is very convenient and its using is very wide. Detection is possible through doors, panes of glass or thin walls.

  1. Can identify day and night: The consumer can adjust work ambient light. 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 "moon" position (min). As for the adjustment pattern, please refer to
    the testing pattern.
  2. Time-Delay is added continually: When it receives the second induction signals after the first induction, it will compute time once more on the basic of the first time-delay rest.
  3. Time-Delay is adjustable. It can be set according to the consumer's desire. The minimum time is 10sec±3sec. The maximum is 7min±2min. 
  4. The switch: "ON","OFF","PIR".







 1.Shut off the power.

2.Loosen the connection column on the bottom of sensor, plug the wire into connection hole, tighten the screws; unload the surface of sensor, connect the sensor into connection box.
3.If you want to install it in quadrate connection box, penetrate the setscrew into installation hole, aim at the installation hole on connection box, then tighten the screw; if you want to install it in circular one, you can use the same way as the quadrate, also adjust the sensor's position, tighten the setscrew on surface, then the fixing arm will open automatically, fasten
the connection box .
4.Switch on the power then test it.




Test  of pir sensor


1.Set the function switch to "ON", Turn the TIME knob anti-clockwise on the minimum after taking the board-  face off. And turn the LUX knob clockwise on SUN position (if you test it in daylight).
2.Switch on the power, the lamp should be on.
3.Set the function switch to "OFF", the lamp should be off immediately, all functions should be in"stop" state.
4.Set the function switch to "PIR", after 30sec later, it enter into working position. The lamp will be turned on after receving the inductor signal.20sec. Under no inductor signal condition, the lamp should be off within 5~10sec.
5.Set "LUX" anti-clockwise to minimum, after it is off when there is no inductor signal condition, the lamp should be off in the daytime, but if you use a opaque object to cover sensor, the lamp should be on, then off within 5~10sec.


When testing in daylight, please turn LUX knob to (SUN) position, otherwise the sensor lamp could not work!





1.Electrician or experienced human can install it.
2.The unrest objects can't be regarded the installation basis-face.
3.There aren't hinder or unrest objects effecting detection in front of the detection window.
4.Avoid installing it near temperature alteration zones, for example: air condition, central heating etc.
5.Please don't open the case for your safety if you find the hitch after installation.
6.If there are some difference between instruction and the function the product has, please give priority to product and sorry not to inform you additionally.
