The Macurco CM-6 is a programmable, low voltage, dual relay carbon monoxide detector, controller and transducer. This electronic detection system measures the concentration of carbon monoxide and provides feedback. It includes an automatic fan exhaust control to help ensure a safe environment in parking garages, maintenance facilities and other commercial applications.

Easy to Use

  • Easy to Install: The CM-6 mounts on a standard 4 x 4 electrical box and becomes the cover for the box. Its modular connectors provide easy installation.
  • User-Friendly Interface: This fully programmable unit contains an interface with selectable fan, alarm relay activation and 4-20mA output. Configurations and settings are easily accessed.
  • User Selectable Digital Display: Allows user to choose whether ppm levels are shown on front display.
  • Quick Field Calibration: Easy, one-screw removal allows access for optional field calibration.

Reliable and Capable

  • Self-Testing: The CM-6 will self-test any time the power is dropped or reapplied, using a programmable option called the Power Up Test.
  • Maintenance Free: No regular maintenance is required.
  • Built to Last: Factory calibrated and 100% tested for proper operation, the CM-6 also comes with a long-life electrochemical sensor for over seven years of continuous operation.
  • Supervised System: Any internal detector problem will cause the fan and alarm relay to activate and the 4-20mA output to go to high.


  • Certified: ETL Listed to UL 61010-1.
  • Time-Honored Quality: Backed by Macrco's reliable brand quality.

Macurco CM-6
Everything went better than expected updating with the CM-6. The new connectors ( old unit wired with wire nuts)with screw compression, were easy to use and everything worked as outlined in the enclosed instructions. Very happy with all to do with detector. Also like the new fault code display.
