How hard is it to replace no-battery-backup smoke alarms with battery backup models? We do have two fire extinguishers and dogs.
There are 2 kind of smokes, battery only, and the ones that are hard wired with a battery backup. Depending upon how your house is set up it can be as easy as going in the attic, and dropping down into each location, or require tearing out drywall. You can only fish so much wire so many ways before it becomes impossible to do, without removing areas of drywall. What makes it hard to do is they all have to be wired together like a chain.
