Product Test: Self-Charging Smoke Detector
You can buy the Dupont Self-Charging Smoke Detector at Kmart.com for $14.99.
The product plugs into a ceiling mounted light socket. No batteries are needed. The product has a built-in battery which is constantly charging.
Erie County Deputy Fire Coordinator, Tiger Schmittendorf helped us to test the product. He started a small fire in the practice tower. It took only a matter of seconds for the alarm to start to sound. It was loud and clear. Our tester was impressed with the product.
There are instructions which have to be followed as far as testing the product.
