The ceiling motion sensors – low voltage series are occupancy and vacancy sensors.
This product line offers 3 models: 360° Passive Infrared (PIR) technology , Ultrasonic technology and Dual Tech that combine both PIR and Ultrasonic. The detection area is up to 1000 ft2 (93 m2) with a PIR sensor and up to 2000 ft2 (186m2) when Ultrasonic is present.
It is suited for use in business and office to detect occupancy and to control the light to save energy. Occupancy Mode and Vacancy Mode are selectable for the installer. The ambient light control system prevents the sensor from turning ON the light if the ambient light is sufficient.
