Smoke alarms are extremely important in keeping you and your family safe in case of a household fire. But they don’t always sound when a fire threatens to break out in your home. Though smoke detector false alarms occur often, that doesn’t mean you should ignore the sound if you don’t see or smell smoke. Smoke detectors can sense hidden fires, such as electrical ones before you can. If an alarm sounds, assume there is a fire and follow proper safety precautions.
