Product Overview

Technology Detects Both Types of Fires

The First Alert 10-Year Battery Smoke Alarm comes equipped with two different sensors to provide early warning. The ionization sensor is more sensitive to detecting flaming fires and the photoelectric sensor is more sensitive to detecting smoldering fires. Smoke particles of varying sizes and number are produced in all fires. For maximum protection, use both types of sensing technologies and have smoke alarms on every level and in every bedroom of your home.
