The OS-550DT is a dual technology occupancy sensor that combines passive infrared (PIR) and high frequency Doppler (HFD) sensor in one housing. By integrating two different sensing technologies with intelligent MCU firmware control logic, the
OS-550DT deliver many advanced features and second-to-none occupancy sensing capability required by today’s building controls and management system.

This sensor provides 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.

The selectable ON and OFF delay setting offer maximum energy management efficiency from reducing the number of unnecessary stop-start cycle. SmartDelay setting feature enables faster sensor installation with easier delay time setting.

The audible Delay-End Warning (DEW) can be enabled to alert the occupant while sensor approaching the 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.
