Constant light control means that the sensor ensures that there is only ever as much light in the room as the light intensity setting specifies. If there is sufficient daylight, no artificial light is switched on. If the amount of light falls below the set level, the sensor automatically switches on artificial light when motion is detected.
Only as much artificial light is added as is necessary to achieve the desired light level – and no more.
The square detection zone is a key feature of the IR Quattro series from STEINEL. Conventional detectors have a circular detection zone. This can lead to blind spots. IR Quattro presence detectors with their square lens provide non-overlapping, uninterrupted coverage of rooms. The patented mechanical adjustability of the reach without loss of quality is unrivalled.
The high-frequency technology invented by STEINEL is capable of detecting movement even behind thin walls made of wood or plasterboard. This is why HF-360 sensors were installed in the school's toilet facilities. Although the sensor is located in the washroom, it is also able to detect people in each of the toilet cubicles.
