Great find and timing. Mine are just getting to the end of the 10yr life and have started beeping. Ordered and heat added :smiley:

You can get them for free from your local fire service.

Due to the huge funding cuts not every fire service gives out free detectors to everyone, some just target over 65's. As a result of cuts fire deaths are starting to rise year on year for just over 7 quid for 2 its money well spent

Aint nobody got time for all that faff of contacting their poor fire service and making them fit one for you. Just spend the measly £7 yourself you freeloading lazy gits.
Heat.

Having had the fire safety inspection etc. they kindly fitted 3 in my house (Hall, landing and computer room). I will say the ones they fit have 10 year lithium batteries in them. So fit n forget (except the odd hoover out and test every clock change). 1 of them has failed and I've replaced with normal, but I do prefer the fire station long life battery ones. Plus the fire station ones have a 10 minute mute button, which is great if they ever accidently go off eg burnt toast etc. Very good deal though. If you haven't got at least 2 working smoke alarms in your house - shame on you!

It's a free service

Nothings free in this world. Someone pays for it.

Thanks, bought these today! Heat added.. :smiley:
