When you sleep, your sense of smell also sleeps. If a fire starts, toxic fumes can overcome you. Photoelectric smoke alarms see smoke and will alert you early, so you can escape. With interconnected alarms, you will be alerted no matter where you are, or where the fire starts. New legislation specifies the type, positioning, and interconnectedness of alarms, which are critical factors for an early warning and quick escape. To give your family the best chance of surviving a house fire, make sure all your alarms are working and properly maintained.
