Operation

The basic principle of operation consists of detecting the frequency shift between a transmitted and a received

signal reflected back from a moving object within the field of view of the unit.

The unit produces a low level output signal which can be amplified and processed to provide an audible or

visual alarm signal and employs low cost surface mount manufacturing techniques which are field proven as

being rugged and reliable.
