DH200PL

The System Sensor Innovair™ DH200 Low-Flow Series photoelectric air duct smoke detectors are capable of sensing moke in air velocities from 100 to 4,000 feet per minute (0.5 to 20.32 m/sec).

This Innovair features DH200  low-flow technology that enables duct smoke detection throughout a broad range of airflow environments. Many difficult to solve HVAC applications occur in low airflow duct applications where reliable smoke  etection is critical. Innovair low-flow technology can detect smoke at air speed velocities of 100 feet per minute or  reater, while continuing the same reliable performance to 4,000 feet per minute.

The DH200 Series Detector samples air currents passing through a duct and gives dependable performance for shutdown of fans, blowers, and air conditioning systems,preventing the spread of toxic smoke and fire gases through the protected area.These intelligent sensors communicate and are continuously monitored through the communication line. Detector sensitivity changes caused by dirt, emperature, or humidity are reported to the panel, allowing compensation algorithms to maintain the sensor's set sensitivity. An advance  ndication at the panel specifies the sensor address, allowing for selected maintenance to be performed as needed.

Remote alarm annunciation can be accomplished by using the RA400Z Remote Annunciator or the RTS451 or  TS451KEY Remote Test Station. Both these devices allow testing of the detector from a remote location.

The Innovair family of DH200  is designed for simplified installation and easy maintenance. The modular construction allows for easy cleaning and uncomplicated field replacement of the UL recognized power and sensor boards.
