But it is a good idea to have BOTH. An electrical fire will knock out your power as well as the smoke alarm.NickB said:Hi Jenny,
Smoke alarms can either be battery powered or hardwired into your property's electrical circuits.
This can be a good idea as you never have to worry about the batteries going flat.
Cheers,

I think you will find that the hardwired type have a battery backup.NickB said:Hi Jenny,

I suspect that any smoke alarms in Canberra when the bushfires hit would have been going off for a week afterwards. It was not possible to see clear blue sky for the next week. Very depressing!Brenda Irwin said:I was wondering about what happens in an area where all homes have a HW smoke alarm installed and bushfires are in the area? Does a whole suburb go BEEP BEEP BEEP all day and night until the bushfire is put out?

Creepy. My dad was a volunteer fireman and sometimes I would visit him on site when he had just finished putting out the flames and had that boring time hanging around to make sure nothing flared up again. It's an eerie feeling especially at dawn or sunset and tendrils of smoke are still wafting up into the sky.GRCee said:And yes when there is a major bushfire smoke dectectors are beeping every where. I was in helensburgh on X/mas night 2001. Even after the fires had passed and houses extinguished. Fire engines turned off and most of the smoke cleared you could hear beep beep from all directions.
