Macurco/3M CM-6 Carbon Monoxide Detector, Controller and Transducer

The CM-6 is a direct replacement for the discontinued CM-21A

Easy to Use
Reliable and Capable
Certified

The 3M 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

Certified: ETL Listed to UL 61010-1.
Time-Honored Quality: Backed by Macurcos reliable brand quality and 3Ms history of customer satisfaction and dedication.
Peace-of-Mind Warranty: This gas detector is guaranteed for a full two-year period from the date of manufacture or it will be replaced or repaired free of charge.
