This movement sensor is designed to provide automatic control of lighting, heating or ventilation loads. It
detects movement using a PIR sensor and turns the load on. When an area is no longer occupied the load will switch
off after an adjustable time out period. An adjustable internal light sensor provides additional energy saving in lighting applications. When an area is occupied, lighting is only switched on when the level of natural light falls below a preset level. When the sensor is first powered up the PIR sensor will always detect immediately regardless of whether the room is occupied.

PIR Sensor Detects movement
Light level sensor to measure light level
Lux sensor will keep light off if there is sufficient natural light

Occupancy Lighting Controllers

Lighting controllers designed for use within offices and warehouses. Available with dual sensors for detecting ambient light and physical movement. Outputs are in the form of switch contacts (standard types). A dimming control output version is available for use with electronic ballasts. This can control up to 10 ballasts, ideal where daylight compensation is required with constant ambient light.
