CRISTALCONTROLS wide view and hallway occupancy sensors enable mounting to a wall, corner, junction box, or conduit. This flexibility reduces contractor installation time and provides a secure and clean finished appearance. CRISTALCONTROLS products utilize the latest passive infrared technology and digital signal processing techniques to provide unmatched detection performance. Additionally, these CRISTALCONTROLS units are available with an integrated microphone to provide overlapping passive acoustic occupancy detection for rooms with obstructions or where occupant motion will be limited.

Basic Operation

Sensors detect movement in the infrared energy that radiates from occupants as they move within the devices field-of-view. Once occupancy is identified the sensor signals a connected power/relay pack to switch on the connected lighting. If equipped with passive dual (PIR/Acoustic) technology, the unit’s microphone is then also enabled to further enhance detection while the lights are on. An internal timer is set to keep lights on during brief periods of inactivity, and is reset every time occupancy is signaled by either the passive infrared or acoustic detection technologies. Additionally, optional daylight detection is available that will turn off controlled lighting whenever there is sufficient ambient light in the space.
