Ceiling Mounted Microwave Presence Detector


The ASENS-C1MW is a recessed ceiling mounted microwave presence detector. Ideally suited to controlling all types of switchable lighting. The unit fits in to a standard single gang accessory box. When movement is detected, the luminaires are switched on. When an area is no longer occupied, the luminaires will switch off after an adjustable period of time.

The internal light sensor provides additional energy saving potential by integrating photocell holdoff. When an area is occupied, lighting is only switched on when the level of natural light falls below a preset level.

The functionality of the ASENS-C1MW is controlled by a number of parameters which can be accessed using infrared remote controls such as the ASENS-CHS5 or ASENS-CHSLCD.
