Traditional smoke alarms will only do this one thing
Defending against fire is a crucial consideration, and smoke detectors perform a critical part in keeping your family safe. Despite that fact, smoke detectors have various limitations. For instance, they are only able to react to smoke, not heat. In the event there is a fire in your residence, you would not be alerted unless the smoke reaches the smoke detector. Even though there are additional unmistakable signs of fire -- like a sharp heat increase -- if there’s a lack of smoke, there is no warning from your smoke detector.
In addition, smoke detectors only beep if they detect ample smoke. When a fire starts small, you may not be cautioned until the situation is out of hand. Some smoke detectors employ dual-sensor technology, meaning they will recognize smoke from both a blazing inferno and a more gradual burn. Whenever they sound their alarm, it falls to the resident to contact first responders after exiting the property.
