Purpose
The CMS monitor is designed to detect carbon monoxide (CO) and hydrocarbons in a compressed air supply. It triggers visual and audible alarms when CO concentrations reach 10 parts per million (ppm). The CMS-1 model is wall-mountable, while the CMS-2 model is portable with a rugged carrying case. Note that CMS monitors do not remove or convert CO.
Requirements for Operation- Compressed-air source of Grade D breathing air (55 to 145 psi) as per Compressed Gas Association specification G-7.1.
- Air flow of 0.5 to 0.8 scfh at 55 psi or more.
- Power supply of 120 volt AC or 12 volt DC.
Description of Operation
After connecting the CMS to the air supply and power source, the system stabilizes in about five minutes. It continuously monitors incoming air, with a green light indicating safe CO levels below 10 ppm. A yellow light and intermittent alarm indicate low air flow or pressure, while a red light and constant alarm signal CO levels at 10 ppm, prompting immediate evacuation.
