I have some 20 y/o hard-wired smoke detectors that I want to replace

If once, you've slept on an island.

Just curious, why replace them, they still work right.
Hmm,
Not after 20 years!!! Would you trust that old detector?

New doesnt mean better to me, to me it means Made in China and maybe
defective. On my hardwired alarm system yes, mine are more than 20 and
get tested once in a while and they are im sure better made than new
chinese crap.
Hi,
Test button test is not real test. Use real smoke and flame(candle) to
test it.
Or spray made for testing. Commercial guys use it.
I replace them every 10 years. Mine are hard wired with 10 year Li.
battery back up. I do same with gas detectors.
