Smoke detector

[Mountain man]

Recently I noticed our vans smoke detector flashing red with no sound after I burnt some toast, pressing the test button the audible alarm sounds. I thought it should be audible at the same time but on speaking to fire angel they say it won’t unless there if heat and flame. Has anyone else’s noticed this.
Thanks Russ

I think it depends on the type of smoke detector, we have a Fire Angle Atom, being an optical type the toast has to be pretty well burnt before it goes off but it does go off.

If it’s a fire angel then the red led flashes every minute or so to let you know it’s working.

Yes I understand that .However mine was flashing constantly with no sound reacting to the burnt toast.

Had you silenced it by pushing the big button in the middle? If so it stays silenced for 15 minutes but will continue to flash.

As Lenny says, some are designed to be toast proof, and I wish one of our neighbours had one.

For clarity ours is a Fire Angel SB1 optical.
Thanks Russ

No just enjoyed my toast whilst watching if flashing.

Having looked at ours it could be needing a good vac out to remove any dust etc.

I think Lenny HB post with mine also being optical fire is probably why it never gave a audible alarm. Need to burn the toast a bit more .
However I will keep an eye on it next time and fit another just in case.
Thanks for all the replies.

The detector sensors do have a finite life, don't they? Add in the tendency of all things electrical to stop working properly about seven seconds before you need to rely on it...

I would say that if you have flashing or static LEDs, or sirens or beeps that isn't described in the instructions, it is knackered. Get a new one. It's cheaper than a new van. I change mine every three years anyway, regardless of what guarantees or assurances are given by the manufacturer. You can only collect on a guarantee, if you are around to collect on that guarantee.

Same with Carbon Monoxide detectors.

The Fire Angel came installed in my brand new van which is now 5 months old. I contacted the company by phone and asked why it was rapidly flashing without an audible alarm when it detected my burnt toast. They said that was correct for model I had, it seems it requires smoldering fire ( heat and flame). However I still was not convinced hence my post on here.
I will be installing the new fire alarm that is now in my possession.
Cheers Russ

The whole point of an optical sensor in an alarm is that it doesn't annoy everyone by going off when there isn't a fire, only burnt toast. Sure, you can get a cheaper one that goes off every time you cook, but it isn't so kind on the neighbours!
