While many people have hard-wired smoke detectors as part of their home alarm systems, they often supplement that system with battery-powered extra units.
Residential smoke alarms need to be on every level and are recommended in every bedroom – especially if doors get closed.
Experts say to change your 9-volt batteries at least once a year and if you think about doing it when the time changes from standard to daylight-saving, it can become a good habit.
Did you already do that? It’s not too late! Do it now!
You’re also supposed to test your alarms once a month – let’s all do that now too!
The biggest mistake we can make is to disable an alarm because it’s going off when we cook or even take a steamy shower. Instead move it a bit to a place where false alarms will be minimized.
There are two basic kinds of smoke alarms. One is the “ionization” type which detects high-flaming fires most effectively. The other is “photoelectric” and is best at detecting smoky fires. So which one to choose?
Fortunately there are dual-sensor detectors and these are judged best overall by FEMA and ConsumerSearch.com.
