Ordinary smoke alarms will only do this one thing
Defending against fire is a crucial consideration, and smoke detectors take on an essential part in keeping your family safe. Despite that fact, smoke detectors have their drawbacks. To illustrate, they are only able to detect smoke, not extreme temperatures. In the event there is a fire in your residence, you might not be warned unless the smoke ascends to the smoke detector. Although there are further significant indications of fire -- such as a sharp increase in warmth -- if there's no smoke, you will fail to get a sounding of your smoke detector.
In addition, smoke detectors only beep if they find enough smoke. When a fire starts small, you may not be cautioned until the situation is out of hand. Various smoke detectors utilize dual sensors, meaning they will detect smoke from both a raging fire and a more gradual burn. If they do go off, it falls to the occupant to notify the fire department after they safely leave the premises.
