Advantages of Precision Detection

Less Nuisance
Distinguishes between cooking smoke or steam and a fire emergency to reduce nuisance alarms and temporarily removing the batteries or smoke alarms in your home.

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.
