Regular smoke alarms can only do this one thing
Defending against fire is a crucial consideration, and smoke detectors perform an essential part in shielding your family. However, smoke detectors have some shortcomings. For example, they can only react to smoke, not extreme temperatures. When there is a blaze starting in your home, you might not be warned before the smoke reaches the smoke detector. While there are further unmistakable indications of fire -- such as a sudden heat increase -- if there's no smoke, you will fail to get a triggered smoke detector.
What’s more, smoke detectors only activate if they find an adequate amount of smoke. In the event a fire starts small, you might not be alerted until the flames are out of control. Many smoke detectors utilize dual-sensor technology, meaning they will recognize smoke from both a blazing inferno and a more gradual burn. Whenever they sound their alarm, it’s required of the occupant to call the fire department after safely leaving the premises.
