User’s Manual
Smoke Alarms
Ionization smoke alarms are generally more effective at detecting flaming fires which consume
combustible materials rapidly and spread quickly. Sources of these fires may include paper burning in a
wastebasket, or a grease fire in the kitchen.
Photoelectric smoke alarms are generally more effective at detecting smoldering fires which smolder for hours
before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding.
For maximum protection, use both types of smoke alarms on each level of your home.
