This device provides continuous protection against the effects of CO, a colorless, odorless, and poisonous gas. It features a digital display that shows detected CO levels and dual LED indicators for alarm and normal operation status. This alarm is suitable for use in homes, rented accommodation, caravans, and boats, complying with EN50291.2010 standards, Parts 1 and 2.

This product is intended for use in indoor residential areas. It is not suitable for installation in a hazardous location as defined in the National Electrical Code.

  • Never ignore a CO alarm. Act immediately upon activation.
  • Do not paint the alarm. Paint can clog the openings and interfere with the sensor's ability to detect CO.

5. Operating Instructions

5.1 Power On

Once batteries are installed, the alarm will automatically power on and begin its initial self-test. The digital display will show '0 PPM' (parts per million) under normal conditions, and the green LED will flash periodically, indicating normal operation.

5.2 LED Indicators

  • Green LED: Flashes approximately every 30 seconds, indicating normal operation and sufficient battery power.
  • Red LED: Illuminates and flashes rapidly when the alarm detects dangerous levels of carbon monoxide.

5.3 Digital Display

The digital display continuously shows the detected carbon monoxide levels in PPM. In the absence of CO, it typically displays '0 PPM'.

5.4 Test/Reset Button

Press and hold the Test/Reset button to:

  • Test the alarm's electronic circuit and horn. The alarm will sound, and the red LED will flash.
  • Silence a sounding alarm for a short period (if CO levels are not critically high).

5.5 Alarm Conditions

When CO is detected at dangerous levels, the alarm will sound a loud intermittent horn, and the red LED will flash. The digital display will show the detected CO concentration. Follow these steps:

  1. Immediately move to fresh air outdoors or open all doors and windows.
  2. Call emergency services (fire department or 911/local equivalent).
  3. Do not re-enter the premises until it has been aired out and the CO source has been identified and corrected.

6. Maintenance

6.1 Weekly Testing

Test your CO alarm weekly by pressing and holding the Test/Reset button until the alarm sounds. This confirms the unit's electronic circuitry and horn are functioning correctly.

6.2 Cleaning

Clean the alarm regularly to prevent dust and debris from accumulating. Use a soft, damp cloth to wipe the exterior. Do not use cleaning solvents or spray directly onto the alarm. Do not remove the cover or attempt to clean the interior.

6.3 Battery Replacement

The alarm will indicate a low battery condition with a chirp and a 'Lb' message on the digital display. Replace all three AA alkaline batteries immediately. Refer to section 4.1 for battery installation instructions.

6.4 End of Life Warning

The Kidde 7DCOC has a 10-year sensor life. After approximately 10 years from the date of manufacture, the unit will indicate an end-of-life warning (e.g., 'End' on the display or specific chirp pattern). When this occurs, the entire alarm unit must be replaced.
