Technical Data Sheet
Note: For safe, efficient blasting, read and follow the owner's manual and seek training for everyone who will use this equipment.
Purpose
The CMS monitor detects carbon monoxide and hydrocarbons in a compressed air supply and triggers visual and audible alarms when CO is detected in concentrations of 10 parts per million. CMS-1 is wall-mountable; CMS-2 is field-portable with integral rugged carrying case.
NOTE: CMS monitors do not remove
CO or convert CO to CO2 Requirements for Operation
• Compressed-air source (55 to 145 psi) of Grade D breathing air as defined by the Compressed Gas Association commodity specification: G-7.1 (www.cganet.com).
• Air flow of 0.5 to 0.8 scfh at 55 psi or more to operate and maintain adequate sampling
• Power - 120 volt AC or 12 volt DC. Line cord provided for 120 volt AC; may be conduit wired.
Description of Operation
Connect the CMS to the air supply and to an electric power source. The system warms up and stabilizes in about five minutes.
Once stabilized, the unit is operational and continuously monitors the incoming air. The indicator light glows green to indicate adequate air pressure and flow, and that the CO concentration is below 10 ppm. The alarm light glows yellow, and a loud, intermittent alarms sounds if air flow or pressure drops.
The air-quality light turns red and the CMS sounds a loud, constant alarm if CO reaches 10 ppm. To prevent CO poisoning, the operators must immediately remove their respirators and exit the blast environment.
