What does a vacancy sensor do?
Vacancy sensors assume that a user will turn the lights on manually, typically via a wall switch. The vacancy sensor will then monitor the space to turn lights off if the space is then vacant for a specified length of time. Occupants in daylit spaces often need no additional electric lighting to perform basic tasks.
Where are occupancy sensors used?
Occupancy sensors, including motion and presence detection technology, can be used to automatically turn on lights, open doors, re-set or adjust thermostats.
Is occupancy sensor a motion sensor?
An occupancy sensor is a kind of motion sensor that will automatically turn on the lights when detecting the presence of a person and automatically turn off the lights when no presence is detected to save energy and provide convenience.
How many types of occupancy sensors are there?
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.
Where are vacancy sensors required?
A vacancy sensor must be installed to control lights in bathrooms, garages, laundry rooms, and utility rooms.
How do you wire a vacancy sensor?
Quote from the video:
Push the wires back into the wallbox. And mount the occupancy sensor to the wall box using the screws that came with the sensor tighten the screws until the sensor is tight against the wall.
Do occupancy sensors need a neutral?
Some require neutral wire, while others do not. Generally if no neutral wire is required, then the type of load is limited to incandescent lights. Some occupancy sensors/ motion detectors turn On automatically, while others are activated by push button. All occupancy sensors turn off automatically.
How are occupancy sensors wired?
Occupancy sensor switch wires each have two black wires, (or one black and one red) and ground (green). One of the black line wires connects to line voltage from the panel, the other black (or red) load wire connects to the light(s). Each black wire can be a line or a load.
