Pass and Seymour dual-technology wall switch sensors
By EM Staff
Legrand/Pass & Seymour introduced dual-technology wall switch sensors to provide “optimum energy management and control” for a variety of commercial applications. Suitable for small offices, executive suites, etc., the sensors offer the choice of automatic ON or Manual ON operation; the combination of passive infrared (PIR) and ultrasonic technologies provides high sensitivity to both small and large movements, along with wide, dense detection. Three control options can set the ON/OFF time delay once occupancy is detected; a self-adaptive option adjusts time delays based on usage patterns, assigning delays as brief as seven minutes when space is typically vacant, and up to 30 minutes for busier times. The product design fits into existing boxes for simple installation, and a bi-level model provides control of two independent lighting loads from the same box.
