Product Description
ILC ILC-SWX-212-1-AR Ceiling Sensor, PIR and Photocell, Large Motion 360 Degree, 2000 Sq Ft, Low Voltage, Auxiliary Relay
Overview
The INTELLIGENT LIGHTING CONTROLS family of ceiling mount occupancy sensors provides a range of control solutions for spaces with finished ceilings (e.g., tiles, sheetrock, and plaster). Preferred by contractors for their simple, yet flexible, mounting methods, INTELLIGENT LIGHTING CONTROLS sensors reduce installation time and fuss. INTELLIGENT LIGHTING CONTROLS products utilize the latest passive infrared technology and digital signal processing techniques to provide unmatched detection performance. Additionally, INTELLIGENT LIGHTING CONTROLS 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. Enhanced options for this sensor family include a photocell that will override lights off if sufficient ambient light is present, active daylight harvesting for 0-10V lighting, and an isolated relay for interfacing external systems (e.g., HVAC/BAS).
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 technology (PIR/Acoustic), 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.
