– CO sensors: tested per maker instructions

Battery Alternative

For battery-powered products, NFPA 72 requires batteries get replaced at least once for each year, unless models use 10-year sealed batteries.

End-of-Life Substitute

Most detectors include finite lifespans:
– Smoke alarms: replace every ten years
instructions CO alarms: replace every 5-7 decades (or per manufacturer)
– Heat detectors: typically 10-15 many years, depending on sort

Recertification for Customized Products

If you modify an accredited product, recertification may be required. Substantial changes to receptors, electronics, or housing typically require retesting.

Part 9: Operating with Certification Body
