Professional Stable Photoelectric Wireless Smoke Detector
Description
Why Are Smoke Alarms Important?
Every year in the United States, about 2,000 people lose their lives in residential fires. In a fire, smoke and deadly gases tend to spread farther and faster than heat. That's one reason why most fire victims die from inhalation of smoke and toxic gases, not from burns. A majority of fatal fires happen when families are asleep because occupants are unaware of the fire until there is not adequate time to escape. A smoke alarm stands guard around the clock, and when it first senses smoke, it sounds a shrill alarm. This often allows a family the precious, but limited, time needed to escape. About two-thirds of home fire deaths occur in homes with no smoke alarms or no working smoke alarms. Properly installed and maintained smoke alarms are considered to be one of the best and least expensive means of providing an early warning of a potentially deadly fire and could reduce by almost half the risk of dying from a fire in your home.
