The MicroSet Dual Tech sensors combination of Ultrasonic and Passive Infrared technologies offers the most complete sensing equipment available today. This pairing helps eliminate false activations or deactivations for additional energy savings. The OMC-DT sensors are also equipped with MicroSet technology which provides a revolutionary adaptive and airflow tolerant technology, making them ideal for spaces which have increased airflow due to higher occupant levels. MicroSet Dual Tech sensors drastically simplify and reduce a contractors installation and adjustment time period. These self adapting, dual technology sensors truly offer some of the most advanced technology available.
