Ordinary smoke alarms will only do one thing
Fire safety is a chief concern for homeowners, and smoke detectors play a vital part in shielding your family. Despite that fact, smoke detectors have their shortcomings. To illustrate, they will only react to smoke, not high temps. In the event there is an emergency in your residence, you may not be warned until the smoke ascends to the smoke detector. Although there are additional telltale signals of fire -- like a sudden rise in heat -- if there’s a lack of smoke, there is no sounding of your smoke detector.
Additionally, smoke detectors only activate if they detect an adequate amount of smoke. When a fire begins slowly, you might not be alerted until the flames are out of control. Many smoke detectors employ more than one sensor, meaning they will recognize smoke from both a blazing inferno and smoldering remnants. Then when they do go off, it’s required of the resident to notify the fire department after they safely leave the residence.
