You have old smokes as battery backup has been required for a long time.. Smokes should be replaced periodically (5 or 10 years?).. The battery backup gives local smoke detection only but better than nothing..

Canadian (or Ontario) regulations may have been different when I installed them about a decade ago, but I think I will update them soon with battery backup units. I'm going to install one in a new three season room I am building so might as well do all four at the same time.
Needed to hear that, thanksfossil said:I know a family who, while sound asleep in the wee hours, experienced a fire in a basically inaccessible spot in the structure of their brand new home that effectively severed both their power and their landline phone. Battery backups in their hard-wired smoke alarms were the only things that alerted them to what was going on. They got the young kids out of the house and used a cell phone to call it in. Family's fine, house was fixed. Scary stuff...saved by a little 9v. battery. I'm glad all my wired alarms have battery backup. Rick
