Traditional smoke alarms will only do one thing
Protecting your home from fire is a crucial consideration, and smoke detectors take on an essential part in keeping your family safe. Even so, smoke detectors have some drawbacks. For example, they will only identify smoke, not extreme temperatures. In the event there is a fire in your home, you might not be cautioned until the smoke rises to the smoke detector. Although there are further significant indications of fire -- such as a sudden heat increase -- if there's no smoke, you won’t have a triggered smoke detector.
What’s more, smoke detectors only sound the alarm if they detect ample smoke. If a fire creeps along slowly at first, you may not be warned until the situation is out of hand. Some smoke detectors utilize dual sensors, which means they will be able to perceive smoke from both roaring flames and a more gradual burn. Then when they do go off, it’s required of the occupant to notify emergency services after they safely leave the residence.
