Traditional smoke alarms can only do one thing
Fire safety is a crucial consideration, and smoke detectors take on a vital part in shielding your family. Despite that fact, smoke detectors have some shortcomings. For example, they are only able to identify smoke, not heat. When there is a blaze starting in your residence, you would not be warned unless the smoke reaches the smoke detector. Although there are additional significant signals of fire -- like a sharp increase in warmth -- if there’s a lack of smoke, you won’t have a warning from your smoke detector.
In addition, smoke detectors only sound the alarm if they encounter ample smoke. If a fire begins slowly, you might not be cautioned until the situation is out of hand. Many smoke detectors employ more than one sensor, meaning they will detect smoke from both roaring flames and something less intense. If they do go off, it falls to the occupant to notify the fire department after they safely leave the premises.
