3M Macurco CM-6 Carbon Monoxide Detector, Controller and Transducer - MA-CM6The low-voltage, dual relay CM-6 helps to monitor carbon monoxide levels by measuring the concentration of carbon monoxide (CO), providing feedback and automatically controlling exhaust fans
3M ID: 70-0715-6500-9
GTIN(UPC/EAN): 0 00 51131 49580 7
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.

- 200 ppm (default)
- Fan Relay: 5 A, 240 VAC, pilot duty, SPDT
- Fan Relay Actuation: selectable at 25 ppm, 35 ppm (default),
- 50 ppm or 100 ppm CO
- Fan Delay Settings: 0, 1, 3 (default), 5 and 10 minutes
- Fan Minimum Run Time Settings: OFF (default), 3, 5, 10 or 15 minutes
- Current Loop: 4-20mA for 0-200 ppm CO
- Operating Environment: 0° F to 125° F, 10 to 90% RH
- Connections: plugs/terminals
- Mounting Box: 4 x 4 electric (not included)
Location:
• In a parking garage or maintenance facility, each unit will typically cover about 5000 square feet. It should cover 900 square feet in a residential or office application.
• The detector should be installed on either a ceiling or wall, normally about 5 feet above the floor in an area where there is good air circulation.
Visual Display:
• The indicator light (LED) will flash green during the self-test cycle. At the end of the 1-minute cycle, the unit will take its first sample of the air and the light will turn solid green.
• The CM-6 displays the current CO concentration (optional). Should the concentration reach the Fan Relay setting, the display will flash back and forth between the CO reading and “FAN.” Should the CO concentration reach the Alarm setting, the display will flash back and forth between the CO reading and “ALR” and the alarm will sound.
Safety:
• Software in the CM-6 continually monitors and tests unit operations. Should a problem be found the Fan and Alarm relays will be activated and the LED will flash green. Pushing the TEST switch inside the unit will allow the unit to go through its 1-minute test cycle and then resume normal operation.
• The gas sensor in the unit is extremely sensitive and should not be exposed to direct spray from aerosols or corrosive gases.
• CO testing on the unit may be conducted with a Field Calibration Kit or quick tested with the CME1-FTG, available through your local representative or 3M.

Features
- Ease of 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 ouput. 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 Macurco's reliable brand quality and 3M's 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.
