The PIR motion detector detects infrared energy emitted from the human body. When a person walks in the detection circumference,the sensor will register a sudden increase of infrared energy. Human body body emits a certain amount of infrared energy about 9-10 micrometers around 32°C . Thus the sensor is typically sensitive in the range of 8-12 micrometers at which a signal will be sent and the door will open.The door stays open until the person is out of range at which the door closes.
Working Specifications
The manually operated activators control; the automatic opening and closing,reduce opening width and sequence opening. It also has reset functions and maintenance indicator to notify when the door has reached its programmed number of cycles.
Safety sensors provide safety features such as electronic safety reverse,finger trap safety,photo cell safety, door speed safety and power failure safety .
NOTE: The same setting can also be utilized In a security system ,instead the sensor sends an alarm signal when the infrared energy of human levels are detected
