My Explosive Gas Alarm is Chirping

Jan 15, 2009

If Kidde's Combination Explosive Gas/Carbon Monoxide Alarm is not installed in the proper location, it can affect the sensitive electronic components in the alarm. Below is a list of substances that at high levels may damage the alarm sensor or cause temporary carbon monoxide (CO) or gas readings, even though neither is present:

  • Alcohol
  • Benzene
  • Ethylene
  • Ethanol
  • Ethyl acetate
  • Hydrogen
  • Hydrogen sulfide 
  • Iso-propanol
  • Toluene
  • Sulfur dioxide 
 
Additionally, most aerosol sprays and alcohol-based products, such as paint thinner, solvent, adhesive, hair spray, after shave, perfume, and some cleaning agents, could damage or cause sensitivity to the alarm.  


To provide optimum performance, prevent unnecessary nuisance alarms, and to avoid causing damage to the unit, please follow these simple steps:

  1. Do not install in kitchens, garages or furnace rooms that may expose the sensor to one of the above substances that could damage or contaminate the unit.
  2. Do not install in areas where the temperature is colder than 40°F (4.4°C) or hotter than 100°F (37.8°C) such as crawl spaces, attics, porches and garages.
  3. Do not install within 5 ft. of heating or cooking appliances. (Kidde recommends 15 ft. to prevent nuisance alarms).
  4. Do not install near vents, flues, chimneys or any forced/unforced air ventilation openings.
  5. Do not install near ceiling fans, doors, windows or areas directly exposed to the weather.
  6. Do not install in dead air spaces, such as peaks of vaulted ceilings or gabled roofs, where CO or gas may not reach the sensor in time to provide early warning.
  7. Do not install this unit near deep-cell large batteries. Large batteries have emissions that can cause the alarm to perform at less than optimum performance.
  8. Do not obstruct the vents located on the alarm. Do not place the alarm where drapes, furniture or other objects block the flow of air to the vents.
  9. Do not install on a switched or dimmer-controlled outlet.
  10. Test the alarm once a week by pressing the Test/Reset button.
  11. Vacuum the alarm cover once a month to remove accumulated dust.
  12. Never use detergents or solvents to clean the alarm. Chemicals can permanently damage or temporarily contaminate the sensor.
  13. Avoid spraying air fresheners, hair spray, paint or other aerosols near the alarm.
  14. Do not paint the unit. Paint will seal the vents and interfere with proper sensor operation.


Move the Kidde CO/Explosive Gas Alarm to a remote location before staining or stripping floors or furniture, painting, wall-papering, or using aerosols or adhesives. However, be sure to reinstall the CO/Explosive Gas alarm as soon as you complete these tasks to ensure continuous protection.
