How does occupancy sensor switch work?
How does occupancy sensor switch work?
An occupancy sensor detects the presence of movement within its given range. The sensor detects motion and transmits the signal to the control unit. If no movement is detected after a period of time set by the user, the controller determines the space is unoccupied and switches off the light.
How many types of occupancy sensors are there?
four types
Occupancy sensors use four types of signals to detect the presence of people: infrared radiation (sensors that detect heat), ultrasonic waves (sensors that detect shifts in sound waves), microwaves, and acoustics.
What is the difference between a vacancy sensor and an occupancy sensor?
When the occupant exits, the sensor automatically indexes the lights back to ‘OFF’ after a programmed delay – typically between two and 15 minutes depending on user preferences. Vacancy sensors take that control one step further with a manual on setting, as opposed to automatic on.
How do you turn off occupancy sensor?
Most manufacturers make it a fairly easy process to disable this main feature of the lights. A switch on the fixture should read “on time,” usually found directly under the motion sensor. Set it to any position, aside from the test position, and flip off the switch that the light is connected to.
How do you troubleshoot occupancy sensors?
Change sensor sensitivity to low. Switch to manual on/off mode. Cover and block some part of the sensor to reduce its sensitivity….Solution:
- Change sensor sensitivity to low.
- Eliminate or decrease the external noise source.
- Relocate the sensor if possible.
How do I reset my occupancy sensor?
Turn the light switch on and off rapidly approximately four times. The light will eventually stay on continuously. Once the light is on, turn the switch off, wait five seconds and turn it back on again. The light should stay off and the sensor should be reset.
