Now that society is developing faster, some high-tech has entered our lives. Of course, infrared switches are a common type. Speaking of infrared switches, we only have some simple understanding. But I don't know how to operate the specific method. In fact, after the purchase, you must install it correctly. Then Xiaobian will tell you how to connect the infrared switch? Inductive switch installation precautions?
Inductive switch installation precautions?
1. The sensor switch works by detecting the presence or absence of infrared light in the human body, and is usually installed indoors. The false alarm rate of the human body sensor switch has a great relationship with the installation position and mode. The sensor switch should pay attention to the following points: The top-mounted human body sensor switch should not be too high from the ground, generally between 2.4 and 3.1 meters. . The wall-mounted human body sensor switch can be installed in the original switch position and replaced directly. Do not operate with power when installing, and then power up after installation. There shall be no screens, furniture, large bonsai or other insulation within the detection range of the inductive switch.
2. Do not use in the super power range. Do not install a switch with a strong airflow such as a doorway or a duct. When installing the human body sensor switch, keep away from heat, air conditioning, refrigerators, stoves and other places where the temperature of the air is sensitive. Do not point the switch straight to the window to prevent the hot air flow outside the window and the person walking will cause false alarms.
How to connect the infrared switch?
1. The sensor switch can be divided into 86 type sensor switch and ceiling type sensor switch from the shape. The Type 86 sensor switch is the same size as a conventional mechanical wall switch and can directly replace the original wall switch.
2. The installation method of the ceiling-mounted sensor switch is similar, taking BR-306C as an example. Open a 60mm diameter hole in the ceiling. The four terminals of L, N, LOUT and NOUT are respectively connected to the live line incoming line, the zero line incoming line, the live line outgoing line and the zero line outgoing line. After the line is connected, the switch can be buckled into the ceiling; if there is no ceiling in the installation environment, the switch top box can be locked on the top with a twisted wire, and then the switch is screwed into the bottom box.
3. Since the left and right sides of the switch have larger sensing ranges than the upper and lower sides, when installing the switch, the positive axis should be perpendicular to the direction of the human walking channel, so that the sensing effect can be achieved. After the switch is installed, the power will be turned on. When the ambient light is sufficient, the bulb will flash three times. After 60 seconds, the initialization will end. The switch will enter the monitoring state. The object will be shielded from the ambient light to make the switch work. If the person does not leave and is active, the switch will Continuous work; after the person leaves, the switch automatically delays the load off.
4. After installing the switch, power up. When the ambient light is insufficient, the switch directly enters the monitoring state. If the person does not leave and is active, the switch will continue to work. If you are not satisfied with the delay time or the light sensitivity value, you can pass the back of the Type 86 wall switch.
