Ceiling Mount Sensors

SWX-200 SERIES

Overview

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

 

Basic Operations

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 ambient light in the space.

Applications

Line voltage sensors are self-contained units that directly power from and switch 120/277 VAC. Typically they are used to control areas where a single sensor’s coverage area is sufficient for the entire space.

Coverage

Passive Infrared (PIR)

  • 8 to 15 ft (2.44 to 4.57 m) mounting height recommended

  • Detection range improves when walking across beams as compared to into beams

  • Lenses can be swapped in field if necessary, contact technical support for assistance

Dual Technology (PIR/Acoustic)

  • Units with dual technology (SWX-221-2 and SWX-222-2) have overlapping acoustic detection of the complete PIR coverage area

  • A PIR event is required to initially enable acoustic detection

  • Sounds indicating occupancy reset the sensor’s time delay while non-occupant noises are filtered out

  • Occupant sounds alone will not keep lights on indefinitely, PIR motion must be periodically detected for lights to remain on for an extended time

  • After sensor time out expires, acoustic detection remains enabled for 10 seconds to enable voice reactivation of lights for additional convenience and safety

Photocell Operation

Sensors with an integrated photocell will turn lights on/off depending on the amount of ambient light detected. This operation makes them ideal for lighting near skylights or windows.

Small Motion 360°

  • Best choice for detection of small motions from sitting occupants (e.g., hand motion)
  • ~500 ftof coverage

 

Large Motion 360°

  • Best choice for detection of larger motion (e.g., walking)

  • ~2000 ft2 of coverage

  • Longest segment of coverage pattern aligns with screw hole axis on sensor (shown as dotted line on Top View diagram below)
