Ordinary smoke alarms will only do one thing
Fire safety is important, and smoke detectors take on a critical part in safeguarding your family. Even so, smoke detectors have some drawbacks. For instance, they are only able to identify smoke, not high temps. When there is a blaze starting in your house, you would not be cautioned unless the smoke reaches the smoke detector. While there are further unmistakable indications of fire -- including a sharp rise in heat -- if there’s a lack of smoke, there is no sounding of your smoke detector.
What’s more, smoke detectors only beep if they encounter ample smoke. In the event a fire begins slowly, you may not be alerted until the situation is out of hand. Many smoke detectors utilize more than one sensor, which means they will be able to perceive smoke from both a raging fire and a more gradual burn. Whenever they sound their alarm, it’s required of the homeowner to contact first responders after exiting the premises.
