Regular smoke alarms will only do this one thing
Fire safety is important, and smoke detectors play a critical part in safeguarding your family. Despite that fact, smoke detectors have some shortcomings. To illustrate, they can only identify smoke, not extreme temperatures. When there is a blaze starting in your residence, you may not be cautioned unless the smoke rises to the smoke detector. Even though there are additional telltale signs of fire -- such as a sudden rise in heat -- if you don’t have smoke, you will fail to get a triggered smoke detector.
In addition, smoke detectors only activate when they detect enough smoke. When a fire creeps along slowly at first, you might not be alerted until the situation is out of hand. Many smoke detectors use dual-sensor technology, which means they will detect smoke from both a blazing inferno and a more gradual burn. If they start beeping, it's up to the resident to notify the fire department after safely leaving the property.
