Following a fire the smoke detector detection chamber will be contaminated.
I would change any sensor that has soot damage/contamination.
Not worth the risk
These devices are to save lives,change them.

Yeah my thoughts exactly lads, never really thought about it to be honest before.

Bin them, they have done the job they were expected to do
Smoke detectors have a life expectancy and should be renewed after about 5 Years to be on the safe side.

Usually 10 years for their life expectancy.
No-one has yet asked ... in the course of acquiring their smoke damage, did they actually 'do their job' in the sense of alerting anyone to the fire - or was the building perhaps unoccupied at the time?

I'm not talking about fire damaged smoke alarms. My point was that smoke alarms in seemingly good condition still only have an effective lifespan of 10 years.
Being a retired Fire Officer anyone asking me that sort of Fire Prevention advice I would go for a lifespan of a maximum of five years, and change batteries twice a year regardless ( this would include Hard Wired Alarms)
Most quality smoke alarms are now stamped with maximum lifespan
Is that just because you are particularly 'cautious' (i.e. want to err on the side of safety)? As you say, most alarms these days have a specified 'expiry date', which virtually always seems to be 10 years from the date of manufacture. Are you not comfortable with the manufacturer's view of the 'safe' lifespan?

No
do they give a ten Year guarantee that means that is the maximum life span regardless of circumstances.
The life span of these items depend on location, maintenance of batteries etc, that is why they should be tested regularly

I can't tell you anything about any 'guarantee', but I think they would probably be on thin ice if such a safety-critical product did not usually (nothing is perfect!) continue to function satisfactorily up to the "replace by" date indicated on the product.
I doubt whether many would disagree with that.
