Someone urgently needs to develop a smoke alarm that (a) doesn't beep when the dog farts; and (b) doesn't need batteries. Otherwise people will keep on dying for want of a £5 device. I don't see why house builders can't be required to install mains wired ones. At my last flat, I had to remove the battery and turn the electric off to stop the alarm beeping. Council electricians wired the alarms on the lighting fuse, which made it interesting on a night
