Description

The AST-IS14 standard transmitter contains a non-dispersive, infrared sensor for carbon dioxide (CO2) detection. It features a display and has an alarm with sound and light that alerts when the levels of CO2 exceeds defined levels. The alarm can be silenced for 30 minutes.

It is low maintenance and is easily fixed on the wall in an appropriate monitoring location for climate control of buildings and different ventilation strategies. It is designed to be connected directly to a BAS or Controller. It requires 24 VDC / VAC nominal voltage power, has 4 - 20 mA or 0 - 10 VDC linear output signals and offers a standard 0 - 2,000 ppm gas monitoring range.
