Regular smoke alarms can only do this one thing
Fire safety is a crucial consideration, and smoke detectors perform a critical part in safeguarding your family. Despite that fact, smoke detectors have various limitations. For instance, they will only identify smoke, not extreme temperatures. In the event there is a blaze starting in your home, you might not be cautioned until the smoke reaches the smoke detector. While there are further telltale signs of fire -- such as a sharp rise in heat -- if there’s a lack of smoke, you will fail to get a sounding of your smoke detector.
In addition, smoke detectors only beep when they find an adequate amount of smoke. When a fire starts small, you may not be alerted until the situation is out of hand. Some smoke detectors utilize more than one sensor, which means they will detect smoke from both roaring flames and a more gradual burn. Whenever they do go off, it falls to the resident to call the fire department after they safely leave the residence.
