Square D / Schneider Electric
The Square D® Ceiling Mounted Dual Technology Occupancy Sensor employs both passive infrared (PIR) and ultrasonic technology to accurately detect occupancy and automatically turn on lighting. To reduce the occurrence of false on events, this sensor employs PIR technology to detect major motion. Once lighting has been turned on, it employs highly sensitive PIR and ultrasonic technology to detect minor motion and keep lighting on while areas remain occupied. When the room or area is no longer occupied, the sensor turns off lighting after a pre-set time delay.
This low profile sensor is ceiling mounted for greatest sensitivity to motion in large areas with obstructions. With a 360 degree field of view and up to 2000 square feet of coverage area, the Ceiling Mounted Dual Technology Occupancy Sensor is ideal for conference rooms, classrooms, bathrooms, and large office areas. These ceiling mount sensors also incorporate an integral light level sensor to prevent lighting from switching On when sufficient ambient light is present, such as is commonly found in windowed areas.
Installation and configuration is simple. The sensor readily mounts to drop ceilings and features front located adjustments for setting sensitivity and time delay. The sensor also features an isolated relay for use with building automation and HVAC systems.
NOTE: Requires 24VDC power pack SLSPP1277. Use optional Slave Relay Pack SLSSP24 to control additional circuits.
