– Smoke sensors: tested within a single year of set up and then every 5 years
— Duct detectors: analyzed within 1 year after which every five many years
– Warm detectors: tested in 1 year and after that every 5 decades
– CO detectors: tested per manufacturer instructions
Battery Replacement
For battery-powered products, NFPA 72 requires batteries be replaced at least once per year, unless devices use 10-year covered batteries.
End-of-Life Alternative
Most detectors include finite lifespans:
— Smoke alarms: exchange every 10 years
instructions CO alarms: replace every 5-7 decades (or per manufacturer)
– Heat sensors: typically 10-15 yrs, depending on variety
Recertification for Customized Products
If an individual modify an accredited product, recertification may well be required. Substantial changes to receptors, electronics, or real estate typically require retesting.
Part 9: Working with Certification Bodies
Choosing a Qualification Body
