These presence detector switches are designed to provide automatic control of lighting, heating or ventilation loads. They detect movement using a PIR sensor and turn 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 is below a preset level.When the unit is first powered up the PIR sensor will always detect immediately, regardless of whether the room is occupied. The /IP variant of these products is sealed to IP55 when used with the gasket pro-vided.
Adjustable time out period 10s to 30m Light Level Light to dark MATERIAL Flame retardant ABS TYPE Class 2 TEMPERATURE -10°C to 35°C
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.
