Passive Infrared Sensors (PIR) Using a patented fresnel lens which minimizes optical aberrations, each Legrand/Pass & Seymour PIR sensor breaks its coverage area into zones. Upon detecting an infrared energy change within a zone, one of the elements in the dual-element pyroelectric sensing device of an occupancy sensor generates a positive pulse. Within milliseconds, the other element produces a negative pulse and the lights are turned on. Vacancy sensors turn lights off when the room is vacant for a period of time, or when there is no infrared energy detected within a zone. Passive infrared sensors are unable to detect occupancy around barriers, and are more effective when sensing movement across their field of sight rather than towards or away from it. All Legrand/Pass & Seymour PIR occupancy sensors feature: n Patented fresnel lenses with multi-segment design n Dual-element pyroelectric sensors n Low-profile design n Daylight filter systems n Adjustable settings for time and sensitivity n Custom Detection Signature Analysis for high immunity to RFI and EMI, and reliability n Self-adaptive technology is available on some models Ultrasonic Sensors Ultrasonic sensors use a multi-directional transmitter/receiver system to broadcast ultrasonic sound waves generated by a quartz crystal oscillator, and then measure the amount of time it takes the waves to return. Movement within the area results in the sound waves returning to the sensor at a slower or faster rate, and thus occupancy is detected. Ultrasonic sensors broadcast in three dimensions, and are therefore able to detect smaller movements than PIR sensors. Proper placement of the sensors is essential as sound waves can escape through open doorways, resulting in false triggering. While Legrand/Pass & Seymour ultrasonic sensors use special circuitry to filter out air-flow movement caused by HVAC equipment or fans, sensors should be kept away from breezy areas. Also, heavy carpeting and other sound-absorbing materials used in the construction of a room will reduce coverage. Legrand/Pass & Seymour ultrasonic occupancy sensor features: n Temperature- and humidity-resistant tuned receivers n Signal Processing Circuitry n Solid-state, crystal-controlled transmitter n Adjustable controls for time and sensitivity Dual Dual sensors combine PIR and Ultrasonic sensing in one device. This minimizes false ONs and nuisance OFFs. Sensitivity adjustments and user selectable operational characteristics make dual technology sensors the most versatile, even in the most difficult installations. L-2 Use dual technology sensors for the most demanding sensor applications. Odd shaped rooms, lots of partitions, and changing floor plans can be handled best by dual technology sensors.
