Occupancy Sensor
IR-TEC International Ltd. is a highly-qualified, Taiwan-based supplier and manufacturer of Detectors, Sensors & Strobes, and Alarm Systems & Accessories. The supplier has been recognized as one of the most professional manufacturers in the industry since 1982. With both experience and innovation, the supplier is confident of providing buyers with quality Detectors.
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. SmartDelay 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.
