Macurco Cm-6 Carbon Monoxide Co (Low Voltage) Fixed Gas Detector Controller Transducer 70-0715-6500-9

Carbon Monoxide Detection and Control

The Macurco CM-6 is a low voltage, dual relay Carbon Monoxide (CO) detector, controller and transducer.

The CM-6 has selectable 4-20 mA output, buzzer and digital display options. It is an electronic detection

system used to measure the concentration of CO and provide feedback and automatic exhaust fan or valve

control to help reduce CO concentrations in parking garages, maintenance facilities or other commercial

applications. The CM-6 is a low level meter capable of displaying from 0-200 ppm of Carbon monoxide.

Selectable options include:

Fan relay actuation: selectable at 15, 25, 35 (default), 50 or 100 ppm CO

Output: Fan relay, Alarm relay and 4-20mA current loop

Controls: Digital display (0-200 ppm), buzzer, fan delay, fan minimum runtime

Installation

Mounts on a standard 4′ x 4′ electrical box

5 A SPDT fan relay controls valves, louvers or exhaust fans

0.5 A N.O. or N.C alarm relay connects to warning devices or control panels

4-20mA current loop – compatible with the Macurco DVP-120 Control Panel

Factory calibrated

Other Features

Supervised system design: detector problem will cause the fan & alarm relay to activate

Optional calibration kit allows the CM-6 to be field tested and calibrated

Location

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.
