My least favorite noise is the low battery chirp that normal smoke detectors emit when low at night. I'm looking to replace my 8 hardwired smoke alarms with new ones that don't have that. I just moved and miss my nest protects only bc this sound doesn't happen. I've read that protects have been discontinued and replaced with these sc5's from first alert . Since I've degoogled I don't really need the "protect integration"

So I need hardwired interconnects (US law afaik bc existing are hardwired) but mostly would like the voice alerts and no battery chirp. I've read that xsense is fairly decent but these new ones that have the voice alerts don't appear to be UL certified so that's a no-go, unless I've just missed it.

I was looking at the anyplace alarms as I saw them in another thread, but can't tell if the low battery notification is a chirp or not? Anyone had any experience with these? They also appear to be out of stock on home depot so no idea if/when they'll be available.

I'm open to all options that are hardwired.

ETA: I've reached out to x-sense to see if the XP0J-SA is UL/ETL certified. I'm waiting to hear back
