The CRISTALCONTROLS family of line voltage ceiling mount occupancy sensors provides a compact control solution capable of switching lighting loads without requiring a powerpack. CRISTALCONTROLS products utilize the latest passive infrared technology and digital signal processing techniques to provide unmatched detection performance. Additionally CRISTALCONTROLS units are available with an integrated microphone to provide overlapping passive acoustic occupancy detection for rooms with obstructions.

Description
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’s internal relay switches power on to the connected lighting. If equipped with passive acoustic detection, 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 ambiant light in the space.
Code Compliance
This wall switch sensor can be used to meet many requirements of ASHRAE 90.1 (2016), IECC (2015) and Title 24 (2016).
