Then you must also recommend, and we of course know you practice,
replacing motion sensors every 10 years, now that must then mean my

last forever, as you said. *You do do this dont you.

A motion sensor is not a life safety item unless you live in a really
dangerous neighborhood. And I have had motion sensors go bad - sealed
units, how are you supposed to clean them?

I have absolutely no problem with you testing anything you want in
your own house, calling it good and living with it. I think it is bad
advice to tell someone to ignore the NFPA and the manufacturers'
recommendations because you don't trust them.

If you make comments like, "Decay of isotope, isnt that for Co
detectors? Who says 20 years, the Manufacturers of course. I have
heard of no independant saying 20
years." where you go zero for two in factual items, I question your
viewpoint as it is/was based on notions.

It is also extremely odd that you claim your smoke detectors cost $150
each. A 20 year old smoke detector - is that in 1989 dollars? They
still make it...? Give me a model number. A typical Honeywell
wireless (more expensive than line voltage) smoke detector is under a
$100 anywhere, and since the OP is talking about checking a circuit,
the run of the mill detector would be somewhere between $35 and $50.
The average three bedroom house can easily be outfitted for ~$300.
That's every ten years.

Perhaps you've been fortunate and never lost anyone in a fire. A
house on our street at my last house burned down and the wife died and
two of the sons were critically injured. I'm not about to tell
people, "Eh, don't worry about the detectors - I'm sure they're fine",
just so they won't have to open their wallet.
