Carbon Monoxide Detector

AERCO offers Macurco CM-6 Carbon Monoxide (CO) Detector. This low voltage, dual relay electronic CO detection system is used to measure and display CO concentrations from 0-200 ppm. The detector can be configured to suit the customer’s needs and the conditions of the site. It can be operated as a stand-alone device, providing an audible alarm if CO levels rise above a configurable set point (a CO concentration deemed to be unsafe). It can also be wired directly to the boiler/water heater, enabling it to shut down the equipment if CO levels rise above the set point.

The unit typically covers about 5,000 sq.ft. (465 square meters) in a parking garage or similar application and 900 sq.ft. (84 square meters) in a residential or office type application. The coverage depends on air movement within the room or facility. Do not mount the CM-6 in a corner. The detector may be installed on either a ceiling or a wall. If installed on a peaked, gabled, or sloped ceiling, it should be located about 3 feet (1 meter) from the highest point. Normally, the unit is mounted about 5 feet (1.5m) above the floor (normal breathing zone), in a central area where air movement is generally good. Additional detectors may be needed near any areas where people work or where the air is stagnant.
