The D-TEK LM was designed to work with many of the Chamberlain operators, like 670, 575, 585 & 595 models. It is a replacement for the original manufacturer vehicle detectors.

The D-TEK LM may also be used in any location protected from the weather to detect vehicles for annunciation, triggering cameras, lighting, etc. where 24VAC power is provided.
