Do you have smoke detectors to wake you so you can escape?
You’re sound asleep when a fast-burning fire engulfs your home. Do you have smoke detectors to wake you so you can escape? Unfortunately, many people don’t. In 2014, almost 3,000 people lost their lives in structure fires and 60% of those deaths occurred in homes without smoke alarms.1,2 The bottom line- Smoke alarms can save lives.
In order to protect your family, pets, and yourself from injury or death during a fire, smoke alarms are essential. Below, you’ll find the best smoke detectors on the market and other basic fire-safety information that can keep your family protected.
Types of Smoke Detectors
Fires happen every day. In 2014, firefighters reported to a blaze every 24 seconds. If you have smoke detectors in your home, you’ll have a better chance of getting everyone out safely. While any smoke detector is better than none.
Multifunctional
Some smoke alarms do more than detect fire. Many include carbon monoxide detection too-giving you double protection in one device. Multifunctional alarms can be battery-operated, hardwired, or smart, so prices vary.
Smart
Smart smoke detectors are cutting-edge in fire safety. They communicate through apps and deliver alerts if an alarm sounds. Smart alarms can talk to each other too, so you’ll know exactly where the fire is coming from if an alarm is triggered. The only downside is that smart devices are more expensive, but you get a lot of safety for your buck.
Battery-Operated
Battery-operated smoke alarms can’t be wired into your home’s electrical system. Instead, they run on batteries. The upside- They don’t require complicated installation. The only hiccup is that they become inactive if the batteries die. Since dead batteries caused about 25% of smoke detector failures in 2014, this is a potential risk you should be aware of.
