Regular smoke alarms will only do one thing
Fire safety is a crucial consideration, and smoke detectors play a vital part in safeguarding your family. However, smoke detectors have their shortcomings. For example, they will only react to smoke, not extreme temperatures. When there is a fire in your home, you might not be alerted unless the smoke reaches the smoke detector. While there are additional telltale indications of fire -- such as a sharp heat increase -- if you don’t have smoke, you won’t have a warning from your smoke detector.
What’s more, smoke detectors only activate if they encounter an adequate amount of smoke. When a fire begins slowly, you may not be cautioned until it's too late. Some smoke detectors use more than one sensor, which means they will be able to perceive smoke from both a raging fire and smoldering remnants. If they start beeping, it's up to the occupant to call emergency services after safely leaving the residence.
