Why my Ei Electronics Carbon Monoxide Alarm doesn't sound when I press the test button?

If your Ei Electronics Carbon Monoxide Alarm doesn't sound when you press the test button, ensure the alarm is correctly secured on the mounting plate. Wait 15 seconds after connecting the power before testing. Press and hold the button firmly for at least 5 seconds. If you have Ei207 models, replace the batteries. If the alarm still doesn't sound after these steps, it should be returned for repair or replacement.
