Install monitors in compressor rooms in close proximity to compressors and 1 - 3 (0.5 meters) close to the floor. Use series 60XX monitors and add a Opera 6000 control unit outside of the mechanical room at eye level to signal a potential risk to occupant entering the room. Controller features a built in audible alarm and strobe.
In applications using compressed nitrogen, the gas displaces air and oxygen (normally 21 percent) resulting in risk of asphyxiation.
