INTRODUCTION
Thank you for choosing First Alert
art smoke alarm designed to provide you with early warning of a fire. Please take the time to read
this manual and make the smoke alarm an integral part of your family's safety plan.
All First Alert
smoke alarms conform to regulatory requirements, including UL217 and are designed to
®
detect particles of combustion. Smoke particles of varying number and size are produced in all fires.
Ionization technology is generally more sensitive than photoelectric technology at detecting small particles, which
tend to be produced in greater amounts by 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 technology is generally more sensitive than ionization technology at detecting large particles,
which tend to be produced in greater amounts by smoldering fires, which may 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 and in every bedroom of your home.
