Regular smoke alarms will only do one thing
Defending against fire is a crucial consideration, and smoke detectors play a vital role in safeguarding your family. Despite that fact, smoke detectors have their limitations. For example, they can only identify smoke, not high temps. In the event there is an emergency in your residence, you would not be warned unless the smoke reaches the smoke detector. While there are further significant signals of fire -- such as a sudden increase in warmth -- if you don’t have smoke, you won’t have a sounding of your smoke detector.
What’s more, smoke detectors only sound the alarm when they encounter enough smoke. In the event a fire begins slowly, you might not be cautioned until it's too late. Various smoke detectors utilize dual-sensor technology, meaning they will recognize smoke from both a blazing inferno and smoldering remnants. If they sound their alarm, it's up to the resident to notify emergency services after they safely leave the residence.
