The PRE4202-PRM is a mid-range microwave presence/absence detector for the automatic control of lighting, heating and ventilation.

The extended range that a microwave detector provides can enable the unit to replace several traditional PIR detectors. This detector has a low profile design which allows flush mounting into a ceiling tile, or surface mounting using an optional back box (PRE3BB). It's reduced head size makes it unobtrusive to occupants.

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 PRE4202 sensors and a selection of other Prefect products.
