I wouldn't jump to that conclusion without checking with someone familiar with them. Those are pretty simple sensors....it's not like they "wear out". Why spend money for no benefit?
The concept behind replacing them every 10 years is based on statistical data showing that after about 10 years the probability of failure increases to some unacceptable amount. Now I don't remember where I was viewing this data, but it was alongside the 10-year rule. The data was used to support the 10-year rule. I also believe these statistics were very conservative in that even after 10 years the probability is still pretty low. Funny thing is I've lived in two houses with smoke detectors that were way over 10 years old. My old house had the original smoke detector from 1974 (house built in 1974)!!! I was curious of the design and pulled it apart and found it to be photoelectric. The smoke detector didn't even work. My current house in calvert had one smoke detector in the entire house (3000 sqft) that was from 1992, that detector didn't work either. So I guess there has to be some point where they simply fail all together.
Now in both cases I did a complete rewire of new smoke detectors and hardwired/networked them. Neither house had networked smoke detectors. I bought a FireX 10 pack from HD and did the entire house. The old house for rental purposes, this house for safety reasons. The only area of the house that dosen't have a smoke detector is the basement. Every BR has a detector.
I suspect the next thing you will see is that every room will require a smoke detector, this is what you see in new construction. Every single room has a smoke detector. I also think what you will next see or possibly see is that the smoke detector must also contain COx, even though the house has no nat gas. Most likely the rationale behind this is to prevent people from accidentally being a dumbass and buying a strictly ionizing detector for a nat gas house. So if we force everyone to get a COx with ionizing detector, then we are safe!!!
Then of course we can go crazy and put a "heat detector" in the attic. I have a photoelectric detector in the kitchen....
I haven't checked smoke detector tech, but I'm curious how well are the "wireless networking" detectors working? I remember years ago someone bought them to avoid doing the hard-wiring. He ended up having to replace the battery every 2 or so mos. I'm curious if they have a wireless that can last 10-years (sealed). That would kinda be worth it..
