The nest protect still chirping even after all nest devices are removed, batteries removed

[karen6]

Bought a new house, have no access to any online nest acct. Installed new ADT system and removed all 9 nest smoke alarms/co2 detectors that were hardwired with backup batteries. Replaced all the backup batteries, chirping continued. Last night we took out all the batteries. We still hear chirping from the hardwiring in the ceiling!

Hello karen6,

Thanks for reaching out to our community.

I understand how frustrating it can be if your Nest Protects seem to be alerting you even though you've made sure to replace the batteries. It's fine, let's see what is going on.

What's most important when making sure your alarms are working as expected is to ensure that they are receiving enough power from the wiring in the ceiling and that none of them are reporting any unexplained alarms. Nest Protects work in such a way that if one of the alarms detects a problem, all of them will notify you about it. This includes but is not limited to low battery/power messages. So, the best course of action would be to dig deeper to figure out which specific alarm is trying to notify you about its status.

Since you've mentioned you don't have access to any Nest account, you can follow this article on how to reset Nest Protect to erase all settings, and set it up with the Nest app. This will help you identify which Protect is the one that is not working as expected, and we can take a closer look at it.

Let me know how it goes.

Regards,
Angel.
