Recessed Microwave Dimming Occupancy Detector


The ASENS-C6MW-PRO is a recess mounted microwave occupancy detector ideally suited to controlling all types of switchable lighting. 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 detector can be changed from presence to absence detection by using the external switch, the ASENS-CHS5 or the ASENS-CHSLCD.

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 ASENS-C6MW-PRO has two channel capability for use with both digital dimming and switched lighting loads. For example, in a classroom, the window row of luminaires can be dimmed down according to daylight detection and the rest of the luminaires are switched on and off only. Two input terminals can be used to manually override the dimming levels and override the luminaires on and off.

The functionality of the ASENS-C6MW-PRO is controlled by a number of parameters which can be accessed using an infrared remote control such as the ASENS-CHSLCD.

Wiring Diagram 1 : Switch And Dim Together

ASENS-C6MW-PRO Wiring Diagram

Switches the luminaire with occupancy detection and maintains illuminance. Dims and switches using the centre biased retractive switch.

Wiring Diagram 2 : Switch And Dim Separately

ASENS-C6MW-PRO Wiring Diagram

Switches both channels with occupancy, maintains illuminance, dims and switches the dimming channel using the single position retractive switch 2. Switches the switching channel on and off using the single position switch 1.

Wiring Diagram 3 : Two Channel, Common Switch

ASENS-C6MW-PRO Wiring Diagram

Switches both channels with occupancy. Maintains illuminance, dims and switches the dimming channel using the centre biased retractive switch.

Wiring Diagram 4 : Single Switch Only

ASENS-C6MW-PRO Wiring Diagram

Switches channel 1 only with occupancy, optional override switch, no dimming output.
