The Overhead Sensor operates by detecting the movement through the detection field and the presence of objects in the detection field.

The Overhead Sensor can be installed in a variety of ways from a recess in a ceiling to being supported by unistrut. The Overhead sensor negates the need for barriers and allows for a more open entrance thereby making the area more inviting to walk into.

The detection pattern of the overhead sensor is made up of 4 rows with 6 detection spots each. This provides a dense detection area of 24 detection spots. As the sensor is microprocessor controlled the presence timer can be programmed as appropriate for the area covered (timing interval available are 2,15 or 60 seconds).

The pattern depth and width are fully adjustable using mounting heights, dip switches and pattern angle adjustments.The unit continously monitors itself with its self diagnostic function and has 4 frequency settings to avoid cross interference between sensors in close proxinmity.
