I have had two of these fail within a couple of years. I managed to get one replaced under warranty but could not find the receipt for the other. I suspect the reliability may mean they won't last 10 years so keep the receipt!

Dont touch these I am awaiting replacements for the second time as these units fail prematurely, usually at around 2-3 years into the batteries alleged 10 year life.

I have OCD, I had to remove and adjust the base to get the alarm to be 'square' in my eyes :smiley:.

I have had mine changed a number of times because they keep failing. I am not sure if this is a newer model. I wasn't aware of the issues reported in the Thisismoney article until I read
this thread. http://www.thisismoney.co.uk/money/news/article-3554501/Top-British-smoke-alarm-manufacturer-admits-90-000-popular-devices-faulty.html

I have five ten year fire angel alarms installed around the house, and all work fine. Fire Angel do also make cheaper models that will require the battery to be replaced every so often. All smoke alarms have a replace before date on them, and this shouldn't be confused as indicating it as a ten year battery model.

Is the short life version a killer device?

Supposedly the Fire Angel St 750 is a fix for the battery problem.

And I believe these units can disable the chirping for 8 hours if you need to sleep

For those moaning about the chirping battery, think about what happens in real life - you remove the battery and then forget to buy a new one, then you have no protection at all.
At least the 10 year battery goes some way to avoid that problem,and it's more relevant in rentals where it's your property that goes up in smoke if the renters don't tell you about their dead battery.

The only thing I don't like is that it is very tricky to line up the lettering on the unit as it screws onto the base, and the base mounting points don't relate to the final orientation of the unit.
This is just a point for those with some level of OCD.

Make sure the base is level (say on artex) because that can stop the unit from turning on.

I quite like these, the casings are quality and they don't look like cheap no name detectors

superhot from me, I always say you cant put a price on your life. We often spend £10 on useless things or a worst takeaway, this is more important than all those things. <3

Some whose 10 year battery life is far less might be because its goes off far more than expected and is not stopped early will run the battery down much quicker,
I have one these alarms for two years and learned to shut the hall to kitchen door before cooking ,now no more alarms.

Don't buy these they're dreadful. Battery supposed to last 10 years but only lasted just over 1 on BOTH I installed. Also one went off in the middle of the night for absolutely no reason terrifying the whole house. AVOID

Yes - they will do it on my annual fire safety check.

I got a new boiler last Dec and British Gas fitted a mains smoke alarm and a separate carbon monoxide detector.

Ok until the extremely annoying intermittent chirping due 'low battery'. Battery cannot be replaced. Avoid imo.

My local fire station supplied and fitted 2 a couple of years ago - both have run out of battery by now - on the back of them it says replace in 2023.

as other stated your local fire st will supply free of charge with advice on house safety.

Free with free home fire safety check. Cold for me as it is good practice to get advice about safety in your home.
