Ordinary smoke alarms will only do one thing
Protecting your home from fire is a crucial consideration, and smoke detectors take on a critical role in safeguarding your family. Even so, smoke detectors have some shortcomings. To illustrate, they are only able to react to smoke, not heat. When there is an emergency in your residence, you would not be alerted before the smoke ascends to the smoke detector. While there are further telltale indications of fire -- such as a sudden increase in warmth -- if you don’t have smoke, you will fail to get a triggered smoke detector.
What’s more, smoke detectors only beep if they encounter enough smoke. If a fire begins slowly, you might not be alerted until it's too late. Many smoke detectors utilize more than one sensor, meaning they will detect smoke from both a blazing inferno and something less intense. If they do go off, it’s required of the occupant to notify first responders after safely leaving the property.
