I used to work for one of the large electrical accessory manufacturers.
I have never heard of an expiry date for smoke detectors.
There are two types of smoke detector technology
One uses a reflective surface ( smoke and mirrors) so there is no wearing parts
The other type uses a nuclear isotope which has an extremely long half life.
Again no wearing parts
Maybe I am not up with tecnology but I have smoke detectors in a number of residential buildings which are over 20 years old and they work
