If you're like 90% of Americans, you're only safe from one type of fire.
Most people think that when they have a smoke detector, they're protected from all fires. This simply isn't true. 90% of US homes have an ionization-only smoke detector. If you're one of these people, it means that your smoke detector may not detect a smoldering fire for 15-50 minutes.
Think about this. In the average home, firefighters agree that many people have as little as two minutes to escape. If your smoke detector is going to take 15-50 minutes to detect a fire, then you're already too late. This is why a dual sensor smoke alarm is so vital to your safety. Both the ionization and photoelectric sensors are vital to your safety from both smoldering and flash fires.
The National Fire Protection Association (NFPA) recommends a dual sensor approach, because you never know what type of fire will strike.
