Regular smoke alarms will only do one thing
Fire safety is important, and smoke detectors play a critical part in shielding your family. Despite that fact, smoke detectors have various shortcomings. For instance, they are only able to react to smoke, not extreme temperatures. In the event there is a fire in your house, you might not be warned before the smoke reaches the smoke detector. While there are additional unmistakable signs of fire -- including a sudden heat increase -- if there’s a lack of smoke, you won’t have a sounding of your smoke detector.
What’s more, smoke detectors only activate when they encounter ample smoke. If a fire creeps along slowly at first, you may not be warned until it's too late. Many smoke detectors use dual-sensor technology, meaning they will be able to perceive smoke from both a raging fire and something less intense. If they sound their alarm, it falls to the occupant to call first responders after they safely leave the premises.
