Oakley FAQ
Do I need to upgrade my older smoke alarms?
If your alarms were installed before 2015 and use replaceable batteries, they still must be functional but may be replaced with 10-year sealed-battery models at next replacement. All alarms should be replaced every 10 years regardless.
Are carbon monoxide alarms really required in all homes?
Yes, if your home has any fuel-burning appliance (gas furnace, water heater, stove, fireplace) or an attached garage. Only all-electric homes without attached garages are exempt.
