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.
Follow Safety Rules and Prevent Hazardous Situations:
1. Use smoking materials properly. Never smoke in bed.
2. Keep matches or lighters away from children.
3. Store flammable materials in proper containers.
4. Keep electrical appliances in good condition and don’t overload electrical circuits.
5. Keep stoves, barbecue grills, fireplaces and chimneys grease-free and debris-free.
6. Never leave anything cooking on the stove unattended.
7. Keep portable heaters and open flames, like candles, away from flammable materials.
8. Don’t let rubbish accumulate.
NOTE: For maximum protection, use both types of smoke alarms on each level and in every bedroom of your home.
Ionization Technology
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
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.
