   FIR 4021 BAT OP PHOTO/ION SMOKE

The Firex 4021

The ionization type alarms are generally more effective at detecting fast, flaming fires which consume combustible materials rapidly and spread quickly. Sources of these fires may include flammable liquids or paper burning in a waste container. The photoelectric type alarms are generally more effective at detecting slow, smoldering fires which smolder for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding. However, both types of alarms are designed to provide adequate detection of both types of fires. If you desire the benefits of both systems, you should install smoke alarms that combine in one alarm both photoelectric and ionization sensing technologies.
