Description :

The OS-550DT is an advanced dual technology occupancy sensor that combines passive infrared (PIR) and microwave (MW) sensing technologies into one housing. By integrating two different sensing technologies with intelligent firmware control, the OS-550DT features second-to-none occupancy sensing performance. This sensor will provide a voltage free, changeover relay output for HVAC or lighting controls when it verifies human presence within its detection area. An ECG output can be linked with 0~10 V dimmer control unit. Its unique ON and OFF offers versatile and custom controls. Smart Delay setting technology enables sensor installation with minimal adjustment. The audible Delay-End Warning (DEW) can be enabled to alert the occupant the approaching of delay expiration. For today's state-of-the-art building management, IR-TEC's OS-550DT dual technology occupancy sensor offers all the edges you need for lighting and HVAC controls.
