All that You Need to Know About Ceiling Occupancy Sensors
Ceiling occupancy sensors are high-tech devices designed and developed to detect whether a designated space or room is occupied or unoccupied. Accordingly, it will turn off and on the lights, fans, and other electrical appliances, thereby saving substantial energy.
The price of occupancy sensors is pretty reasonable. They are easy to install and use, and due to their high energy-saving properties, they are extremely popular. The fact that they have several energy code mandates has made these sensors a staple for modern buildings – both domestic and commercial.
What inputs do they need?
These occupancy sensors can be categorized into three types - manual, partial, and full ON devices. In most commercial buildings, the energy codes need a manual or partial-ON operation. The Manual-ON sensors, also termed vacancy sensors, need the occupant of the space or room manually switch off the appliances. It will activate the sensor if the switch is integrated with the sensor circuit.
The Partial-ON sensors activate the appliances to a particular predetermined designated level (like 25 or 50%) and then the occupant has to use a switch to get the full output of the appliances. FULL-ON sensors, on the other hand, will instantly activate the appliances to their full output.
The Manual-ON and Partial-ON sensors save more energy than the FULL-ON sensors, with the latter providing more convenience, and it is often regarded as an added amenity.
What are their outputs?
A ceiling occupancy sensor (or a vacancy sensor) may turn off the lights and fans or can reduce their output with the help of dimming or stepped switching. While the ON/ OFF mode is pretty common, the light or appliance output reduction is applicable in cases where the light and the fan must remain functional even if the room or the space remains unoccupied frequently – for instance, the stairways.
The Coverage pattern and Area
The sensitivity of the modern sensors defines the distance from which the sensor can detect the entry and exit of the occupant and the area circumference it covers. This resulting coverage range is termed as coverage pattern and area. In other words, the coverage area expresses the boundary within which the sensor will work and detect the motions. Now the shape of this area may differ and can be circular, elliptical, rectangular, teardrop, and so on.
Ensure to get ceiling occupancy sensors from a reputed company to get optimal benefits.
