Typically, when we see the word ``end'' displayed on a carbon monoxide or smoke detector, it means the device is at the end of its functional life, and should be replaced. If it's 10 years old or older, it should be replaced anyway. But it sounds like your unit is not working anymore, and should be replaced ASAP.
Your alarm will indicate end of life seven or ten years after initial power. It will 'chirp' every 30 seconds. The chirp will not stop until the unit is powered off.
End-of-life- ERR will appear once the alarm has been active for its 7- or 10-year life to signal an end-of-life warning. Power Surge- If you think a power surge is the cause of the ERR message, press and hold the Test/Reset button for 5 seconds.

Here's a simple guide: Smoke alarms alert you with three beeps in a row. Carbon monoxide alarms alert you with four beeps. A single chirp means the battery is low or the detector should be replaced.
Replace and upgrade your smoke alarms every ten years.
Smoke and carbon monoxide alarms must be replaced within the specified lifetime of the product, usually 5 to 10 years after the date of manufacture. Check the back of your alarm for the date of manufacturing or contact us if you need assistance.
After ten (10) years of cumulative power up, this unit will “chirp” two times every 30 seconds. This is an “operational end of life” feature which will indicate that it is time to replace the alarm. To help identify the date to replace the unit, a label has been affixed to the side of the alarm.
Clear Residual Charge to Stop the Chirp
Open the cover and take out the battery. Press and hold the test button for 15-30 seconds. This will fully reset the smoke alarm and drain any charge left inside. Insert the new battery and close the battery compartment.
False or nuisance alarms are when your smoke detector or CO alarm goes off, but there is no presence of smoke or carbon monoxide in your home. However, if your smoke or carbon monoxide detector sounds indicating an emergency and you are not certain it is a nuisance alarm, evacuate the home and call 9-1-1.
If you think your carbon monoxide alarm is nearing its end-of-life, replace it today. *Models equipped with end-of-life hush feature can be temporarily silenced for 3-day intervals for a total of 30 days.
A typical Kidde CO detector that you buy from a big box store only goes off when it detects CO concentrations of 40 PPM over 10 straight hours. And that's the lowest concentration that will sound the alarm! It also goes off when there's 50 PPM of CO in your home for 8 hours – the OSHA standard.
If your digital carbon monoxide alarm says “END” on the display, this means it has reached the end of its life and needs to be replaced. The alarm will also chirp 5 times per minute to let you know it's time for replacement. Learn more about CO Alarms: Where to Buy First Alert, Onelink, or BRK Brands Products.
