In the event of a fire, a smoke alarm can save your life and those of your loved ones. They are the single most important means of preventing fire fatalities by providing an early warning signal — so you and your family can escape. Smoke alarms are one of the best safety features you can buy for your home, and because they are mass-produced, you can purchase one for as little as $7.

There are two methods for operating these detectors. They can be wired directly into your home or a simple 9-volt battery can power them. In new construction, direct-wired detectors are mandatory. These are most reliable and don’t depend on the homeowner remembering to change the batteries. But for retrofit situations, a battery operated unit is acceptable. It is recommended that every home have one smoke detector per level, and one in the garage.
