So apparently the co² detector or the smoke detector is beeping 3 times every 1 minute co² number shows 0 for co² and smoke detector saying nothing so idk if it is supposed to do this. It's annoying as f*ck.

It should be a CO (carbon monoxide). it is probably the batteries. They make those things loud.

Needs a new battery more than likely.

Very annoying. If all is normal, that periodic beeping is probably telling you to change the battery.
So change the battery.

It means "it's time to change the battery".
