Smoke alarm failures
 
45% due to bad positioning, 20% no battery. So why did the rest fail?

https://www.bbc.co.uk/news/uk-england-50598387

How badly does it need to be positioned to cause it not to work?

Flat battery/fault in the device?- Plus some people/children can't hear them.

They count as a failure to work any fire they attend where the alarm
didn't go off. So it includes where the fire was not close enough to
the alarm, including in an area not covered by the alarm. Easy enough
in terraces I think - eg fire in the kitchen at the back of a house
with only one alarm on the first floor landing at the front.

But I did once find the sole alarm in a bungalow on a shelf in the
airing cupboard - 'cos she "was worried about all those clothes over the
cylinder".

Presumably the alarm is too old.

Or the wrong technology.

Presumably In a room with a closed door to where the fire started etc.

In a past life and as a contractor I installed cheap smoke alarms in a lot
of warehouses nationwide. The batteries were very cheap. When I muttered
about this I was told to STFU. 12 months later I visited the sites for the
annual service. Every alarm was chirping due to flat batteries. Not one
manager picked up the phone to report this. It is a long drive to
Southampton and back.

If the doors are closed it may not go off until the fire reaches the
room that it is in. Another only recently discovered problem is that
young children can sleep through a standard smoke alarm noise!

I have a strange sensitivity issue on mine. The placement is good when it
works it detects the faintest trace of burnt toast as its in the stairwell,
however although the test button says it is fine, I have noticed that some
days when a bit of crust does burn a bit more than intended, it does not
always go off, yet on other days, it goes off with the merest hint.
I have to conclude there may be a dry joint somewhere in the circuit and
pressing the button stresses the pcb enough to make a better connection.
Trouble is, its glued to the landing beside the stairs and has been painted
around, so I'd need to get a bigger one or make up some kind of panel to put
it on. I really don't want to have though paint the paint in the hall just
cos I changed the smoke alarm!

Since the fire service if they fit one stick it on a pole and use double
sided tape to stick it on the ceiling, perhaps after a while it falls off
and gets damaged? :-)

On mine if the battery is going down it bleeps every few seconds, normally
starting about 3 am in the morning.

You can have one in each room if you are paranoid of course.
Personally havving been present at some fires, it is a miracle if at least
one does not go off, as smoke does get everywhere pretty fast in my
experience

We have six (interlinked).

- Two in the living room, which is fairly isolated from the rest of
the house and has a deep beam down the middle.
- One in the kitchen (heat rise)
- One in the hallway
- Two on the landing (which is L shaped)

Could it just be contamination of the sensor - being installed in a very
dusty or greasy atmosphere. I've seen ceiling mounted alarms that
almost have a fur covering where dust has stuck to a sticky geasy case.

5. Vestibule (electricity intake etc), hall, Lounge, bedroom1, bedroom 2. Kitchen heat and CO detectors. All interlinked.

Should really have one in bedroom three to make the system compliange with Grade LDwhatever but I think it's unlikely anyone will be in bedroom 3 alone in the house.

Only 5???

I have 2 heat detectors and 10 ionisation smoke detectors all interlinked here

along with 4 CO alarms also interlinked.

They are also set up as two 24 hour zones on my intruder alarm panel too.

As a reflection of my own anxieties I've even gone so far as to wire in a Shelly smart relay to one of my interlinked smoke alarms so not only does it disable the MVHR system but also sends me a text to say it's gone off! I do wonder how I'll react if I ever get that text...

Some of them seem especially sensitive to toast €˜smoke. We had one which
used to trigger before the toast had a decent sun tan.

Its replacement was chosen, partly, as it claimed it is resistant to false
triggering. So far it has been.

When I rewired TMH's daughters house I installed 6 in a 2 bed terraced
house but these were all escape routes and not in the bedrooms.

That was Labour propaganda.

If you are living in social housing, and you are living on benefits, and
you have a spare room that you could reasonably let out, you lose some
benefits.

You could of course ask to be moved to a smaller property.

Mind, that was the intent. In a few cases the "spare" room was required
for disability

And there were, in most cases, no smaller properties available - but you
were still expected to pay.
