Kele Toxic and Combustible Gas Detectors GDS Series

Kele Toxic and Combustible Gas Detectors

 

The Kele GDS Series Gas Detector is an independent microprocessor-based system. It provides continuous, effective toxic gas monitoring and combustible gas monitoring for building automation systems, BAS. The system detects, senses and monitors gases for environmental safety and control. The GDS Series provides a 4-20 mA output in proportion to the level of gas present and two relay outputs to activate additional horns, strobes, or ventilation systems. The gas detectors feature a functional and flexible design with pre-calibrated plug-in sensors. The unit features a two-line LCD for local indication, self test diagnostics, and a built-in 85 dBA buzzer. The rugged polycarbonate housing is resists rust, corrosion, and dents. When properly installed and maintained, the GDS Series Gas Detector can be used in a control system to prevent the formation of a hazardous environment.
