Advantages of Precision Detection

Less Nuisance

Early Warning

Provides an early warning because today’s home furnishing and materials burn hotter and faster and may result in less time for a safe evacuation if a fire breaks out. 

Why Precision Detection Matters

Escape times have reduced from 10-15 minutes in the 1970’s to 1-2 minutes today

Cooking nuisance alarms are the #1 reason why people disable their smoke alarms

Almost 3/5 home fire deaths resulted from fires with none or no working smoke alarms

A fire department responds to a fire every 21 seconds in the United States
