Unlike fixed head microwave detectors, the PRE4203 offers a unique presence/absence detection capability by using an adjustable head for improved accuracy of operation.
This incorporates an innovative locking mechanism to prevent tampering. By changing the angle of the head, different detection patterns can be achieved to suit the application. An integral sensitivity adjustment allows the detector to be fine-tuned to its environment. The detector is self-contained and can be flush or surface mounted using a separate detector back box.
All timings, light levels, and all other parameters are programmed via the PRE5901 or PRE5903 programming handsets. Once programmed the parameters are fully tamperproof. One handset will program all PRE4203 sensors and a selection of other Prefect products.
