mains powered smoke alarms with out battery backup

[Daveyboy]

Out of curiousity, is there a regulation thats states mains smoke alarms have to have a battery backup? Obviously make sense to for just a few extra quid.

Its all covered in the relevant BS for fire alarms. Can't remember the BS number though, but a web search will give you all the info you need.

No battery backup is about as much use as a chocolate kettle, if there is a power cut in the night, the alarms wont work!

BS 5839 is the relevant British Standard.

Approved Document B1 of the building regs is also applicable.

In new builds a category D, LD2 system is the minimum required system to be installed.

If you look uo the definitions of categories, you will see a category D system is one with mains powered alarms WITH a battery back up.

Why would anyone waste the money or for that matter take the risk of installing Smoke Alarms without backup ?.

Thats why I asked, as a customer doesn't want a battery backup.

I'd just put them in as normal and tell them they don't have the battery back up. That way if they ever have a power cut they'll thank you when they realise

Tell them it's a Legal Requirement for you to fit Alarms that have Battery Backup.
Ther'es some strange folk about, a few years back we had a Local Authority contract to Fit smokes in all of their properties. Went to 1 house & the woman told us to F off, she did'nt want them. I tried to tell her they were free & could save hers & kids lives in the event of a fire, her answer was why bother we've all gotta die sooner or later.

Fit ones with capacitor back up they cost lots more and then you can truthfully say no battery back up!

.... for just a few extra quid.

What's the price difference between smoke alarms with a battery reserve and ones without?

Probably around the £3 to £4 mark, so peanuts really for the added safety.
