new builds --- what kind of smoke detector systems are being installed?

i ask because we renovated this 1970s era house and it had exactly ONE yellowed-out smoke detector in the house so i decided to do a little research.
bought an x-sense hub and about 15 smoke & C02 detectors. the cost was minimal; well under $300 and it has these features:
- creates its own MESH network making the entire system very robust and strong
- you can name every device in the house
- STUPID easy install. STUPID EASY. one anchor & screw, done.
- it speaks the name of the device out loud going off so there's no question what room is on fire
saving precious seconds as well as displays the notification on your phone.
- tap your phone notification to silence them all
- i'm 2 years in and every unit still shows battery life > 95%
i have to ask; are builders still puttting shitty 9v battery 'hardwired network' giant plate devices in that turn yellow in 2 years and chirp constantly?

I have
and they also do these things
they haven't, however,
That system you have a hard on for looks nice, but I'm not sure what the issue is with with any modern residential smoke / CO detector system, if installed properly and adequately.
That said, SMOKE and CO DETECTORS SAVE LIVES. Friendly reminder to everyone to check their shite.

ngl, $300 for all that screams short life, false alarms and glitches. i.e chinese special.
Speaking the name of the room would be very helpful though. All of my hardwired are starting to chirp from low batts. Pain to find the one chirping.
The biggest reason to have alarms is just being able to put the fire starter out as quickly as possible. Could be the difference in a minor kitchen fire thats fixed with opening the windows and a complete house fire. And when you are asleep, being woken by a fire usually means its gone too far to do anything but gtfo.

that was my question; i'm wondering if they are installing smart systems these days or if you don't watch your construction build like a hawk, they just put in those dinosaurs the size of salad bowls that need new 9v batteries every couple of years.
it seems like unnecessary wiring to link them together in 2025 and an expensive item on your home build when thats not necessary.
eta the x-sense system is on amazon, walmart, etc and has great reviews from various tech sites so its not just 'cad and his chinese junk'.

They did 5yrs ago when I built our house and I can stand them because I can never find the one that is setting them off.

could be the wired ones are UL listed or otherwise have a certificate that the builders and their insurance can stand behind in case of a lawsuit. Safety items are the last things to keep up with technology.

They're probably installing whatever the local supply houses carry unless someone specifically says they want something different.

From my years in the fire department (relatively recently) I never came across any smart systems like that, and we responded to a lot of upper class homes and new builds.
The system in my house has a "primary detector" in the hallway and smaller satellite detectors in each room. They are all connected so that when one goes off they all go off, and the primary announces which room is in active alarm. They are also powered by my breaker panel. The battery in each one is for backup when the power goes out. They were changed when we bought the house 7 years ago, and when we replaced all the detectors in 2023 when they expired. ETA they each have a 10 year lithium battery.

My home security system has smoke and carbon monoxide detectors. All wireless/battery powered and we have yet to change them in the 7 years we've lived here and installed.
