A continuous chirping sound from your First Alert Carbon Monoxide Sensor (model 1039731) after changing the batteries and moving the unit to a different location could be caused by a few different issues. Here are some steps you can take to troubleshoot the problem:
-
Check for Proper Installation: Ensure the batteries are installed correctly, with the correct polarity. Even a slight misalignment can cause the unit to malfunction.
-
Reset the Unit: Try resetting the carbon monoxide detector. To do this, remove the batteries and unplug the unit from the wall (if applicable). Press and hold the test button for 15-20 seconds. After this, reinsert the batteries and plug the unit back in. This reset can sometimes clear any errors.
-
Battery Quality: Make sure you are using fresh, high-quality batteries. Low-quality or partially depleted batteries can cause the unit to chirp even if they are new.
-
Sensor Malfunction: If the sensor inside the unit is faulty or has reached the end of its life (typically 5-7 years), the unit might chirp continuously to indicate it needs replacement. Check the manufacturing date on the back of the unit. If the unit is old, it might be time to replace it.
-
Environmental Factors: Sometimes, environmental factors such as high humidity, dust, or chemicals in the air can cause the detector to malfunction and chirp. Ensure the unit is placed in a clean, dry area, away from any strong chemicals or fumes.
-
Check for Error Codes: Some units may display a blinking light or other indicator to show a specific error code. Refer to the user manual for more information on what these codes mean.
