Regular smoke alarms can only do one thing
Fire safety is important, and smoke detectors play a vital part in shielding your family. However, smoke detectors have some drawbacks. For example, they will only detect smoke, not high temps. When there is a blaze starting in your home, you would not be cautioned before the smoke reaches the smoke detector. While there are additional unmistakable signs of fire -- such as a marked rise in heat -- if you don’t have smoke, you won’t have a triggered smoke detector.
In addition, smoke detectors only sound the alarm if they encounter an adequate amount of smoke. If a fire starts small, you might not be alerted until the situation is out of hand. Various smoke detectors utilize more than one sensor, meaning they will recognize smoke from both a raging fire and a more gradual burn. Then when they do go off, it’s required of the homeowner to contact emergency services after exiting the property.
