Occupancy Detectors & Switches

the perfect partner for reducing the energy consumption of heating, lighting and ventilation

 

Occupancy Detectors (also known as ‘PIR Detectors’) are a quick, effective and low cost solution for reducing the energy consumption of lighting, heating and ventilation.

 

How do they work?

An occupancy detector monitors the area (detection zone) for any movement and will automatically turn the lighting (other connected load) on when a person is detected. When the area is vacated, the lighting will automatically turn off after the preset time delay has lapsed. A light (lux) sensor is in built into our PIR sensors to ensure that the lighting is not turned on if there is enough natural light available.

 

What is a Typical Application for Occupancy Detectors?

Occupancy Detectors and Switches have a variety of applications.  They are most commonly used as motion detectors for lighting.  They can control an individual room or a whole corridor and stair well.  The automatic control of heating or cooling is often a key application for these occupancy detectors so that rooms are only ever heated or cooled when a room is occupied.  Our customers have also used these PIR sensors conjunction with our humidistats to control the ventilation of infrequently occupied spaces.

 

What is the capital investment?

Time Delay Switches range from £35.00 for a standard motion sensor with light level control up to £46.50 for a sensor that includes a switch to override the automation.

 

How long is the payback period?

This is very much dependent upon your application and usage.  The average payback period is 12 months.

 PIR light switches are ideal for use in the home for when the family forget to switch off the lights .

Motion sensor switches are great for use in the home to automatically turn lights off when people leave the room.
