  • Page 4: General Safety Information

    1 General Safety Information The following instructions are intended to serve as a guideline for the use of the Macurco CM-6 and CM-12 Carbon Monoxide Detector. This manual will refer to these devices as CM-xx unless content is specific to a model. This manual is not to be considered all-inclusive, nor is it intended to replace the policy and procedures for your facility.

  • Page 5: Use Instructions And Limitations

    The CM-xx meets the requirements of the Uniform Building Code for enclosed garages and meets OSHA standards for CO exposure. CM-xx can be used stand alone, with the Macurco DVP-120 Detection and Ventilation Control Panel, other 12 VAC or 24 VDC fire/security panels or building automation systems.

    Calibration kit is available. One screw allows access for calibration or gas test Where required by federal, state, local regulations or the Authority Having Jurisdiction, CM-6 and CM-12 are required to be used with Listed Horn/Strobe model 78-2900-0211-X* to meet the 85dB(A) Audibility requirements of Standards UL 2075.

  • Page 7: Installation Instructions

    2. Connect the CM-6 to Class 2 power supply only. It is suggested to use a separate transformer for powering the unit or units because of possible interferences from other devices on the same power supply.
  • Page 8 Macurco CM-xx Operation Manual 8. The Fan Relay can be configured for latching or non-latching (default) when activated (when the gas concentration exceeds fan relay set point). Once latched in, power will need to be interrupted or the “TEST” button pressed to un- latch the relay condition.

  • Page 17: Terminal Connection

    Mains Power Connection Connect the CM-6 to Class 2 power supply only. It is suggested to use a separate transformer for powering the unit or units because of possible interferences from other devices on the same power supply. Connect the CM-6 to the control cables with terminal plugs.

  • Page 18: Operations

    Mains connections should be done in accordance with National and Local Electrical Codes. Only qualified personnel should connect Mains power to any device. Macurco recommends a minimum wire size of AWG18 and the wire insulator must be rated for 140°F (60°C) service. The modular connector will accept wire from 12 to 22 AWG.

  • Page 23: Troubleshooting

    Macurco CM-xx Operation Manual 5 Troubleshooting 5.1 On-Board Diagnostics The CM-xx monitors all critical functions of the unit through software diagnostics that continuously test and verify unit operations. If a problem is found, the unit will switch to a fail-safe/error mode or trouble condition. In this error mode, the Alarm relay will be activated, the 4-20 mA current loop will go to 24 mA, the unit will display the error code, the green status indicator LED light will flash, and the buzzer will chirp intermittently.

  • Page 24: Sensor Poisons

    6 Maintenance The CM-6 is low maintenance. The unit uses a long-life electrochemical sensor that has a 10-year life expectancy (in normal conditions). The detector’s performance should be tested regularly by using gas as detailed in the Testing and Field Calibration sections.

  • Page 25: Cleaning

    1-844-325-3050. All CM-6 units are factory calibrated, 100% tested for proper operation and accuracy of ±10%*. During normal operation the green status indicator LED light will be on steady, the fan & alarm relay will be in standby mode and the 4-20 mA output will be at 4mA (in clean air).

  • Page 26: Testing

    7.1.1 Operation Test Check that the green CM-6 status indicator LED light is illuminated continuously. If not, do not proceed with the tests. If the unit is in error mode, contact your local representative or Macurco technical service representative for information on resolving the problem.

  • Page 27: Calibration And Test Kits

    A Field Calibration Kit, Cal-Kit 1, and one bottle of calibration gas is needed to complete gas test. These are available through local distribution or from Macurco. NOTE: CM-xx must be tested or calibrated at regular intervals in accordance with the requirements of the National Fire Protection Association (NFPA) 720 or local code requirements.

    5. Turn on the regulator to start the gas flow and wait with the gas applied continuously. 6. With the display function turned “On”, the CM-6 will show the current concentration of CO or “0” (zero) in clean air. When the CO concentration reaches the Fan Relay setting (35 ppm, for example) the display will flash back and forth between “FAn”...
