Regular smoke alarms will only do one thing
Fire safety is a chief concern for homeowners, and smoke detectors perform a critical part in shielding your family. However, smoke detectors have some drawbacks. For example, they can only react to smoke, not high temps. When there is a blaze starting in your house, you would not be alerted until the smoke ascends to the smoke detector. Even though there are some other significant indications of fire -- including a marked increase in warmth -- if there’s a lack of smoke, you won’t have a sounding of your smoke detector.
What’s more, smoke detectors only sound the alarm when they detect ample smoke. If a fire creeps along slowly at first, you may not be warned until it's too late. Some smoke detectors use dual-sensor technology, which means they will be able to perceive smoke from both a blazing inferno and something less intense. If they start beeping, it’s required of the resident to call emergency services after exiting the premises.
