Early Warning

Father and son are reading in the living room, a Early warning infographic in the foreground.In a home fire emergency, every second counts. Modern homes tend to be built and furnished with lighter, synthetic materials that burn hotter and faster - and feature layouts with higher ceilings and open floor plans - that may result in less time for a safe evacuation if a fire breaks out. Escape times have reduced from 10-15 minutes in the 1970’s to 1-2 minutes today (NFPA). Precision Detection helps better detect fires in homes built and furnished with modern construction materials where fires can spread more quickly and provide an early warning. Install Precision Detection alarms and create an escape plan with your family to help be prepared.



Reduce Nuisance Alarms

Mother and son are cooking in the kitchen, a less nuisance infographic in the foreground.This advanced sensing technology also better distinguishes between nuisance cooking alarms and a fire emergency. The #1 reason why people disable smoke alarms in their home is due to nuisance alarms caused by cooking or steam leaving them unprotected (NFPA). Almost 3 of every 5 home fire deaths result from fires with no smoke alarms or no working smoke alarms (NFPA) so it is important to install and maintain your home’s alarms. Installing alarms equipped with Precision Detection and following proper placement of at least 15 feet away from cooking appliances will help reduce nuisance alarms.
