Regular smoke alarms will only do one thing
Defending against fire is a crucial consideration, and smoke detectors perform an essential role in shielding your family. However, smoke detectors have some limitations. For instance, they will only react to smoke, not extreme temperatures. In the event there is an emergency in your residence, you would not be alerted unless the smoke reaches the smoke detector. Even though there are further significant signals 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 activate when they find ample smoke. If a fire creeps along slowly at first, you might not be cautioned until the situation is out of hand. Various smoke detectors use more than one sensor, meaning they will recognize smoke from both roaring flames and something less intense. Then when they start beeping, it's up to the resident to notify first responders after exiting the premises.
