The ALC-CMP-DT-BT is a Dual-Technology (PIR and Ultrasonic) Sensor designed for use with the ARISTA Lighting Controls System by Intermatic and will control lighting based upon occupancy/vacancy. If space is configured for Occupancy and movement is detected, the sensor informs the ARISTA controller(s) in the space and the lights will illuminate. The lights will turn off after the ARISTA controller(s) deem the space vacant and the timeout period completes. If space is configured for Vacancy, the ARISTA controller(s) in the space will only react when they are manually activated. The lights will turn off after the ALC-CMP-DT-BT deems the space vacant and the timeout period completes. This sensor provides a 360 coverage pattern, PIR Coverage - Up to 1300 ft - US Coverage - Up to 1600 ft. Pricing Available Upon Request.
