Changing your clocks this weekend? Give your smoke alarms a check, too.
On Sunday, November 1, clocks fall back from 2 a.m. to 1 a.m. It is a useful reminder to press test, check manufacture dates and replace alarms that fail or have reached the end of their service life.
Since January 1, 2023, Illinois generally requires newly installed or replacement battery smoke alarms to use self-contained, non-removable, long-term batteries. The Illinois State Fire Marshal describes these as 10-year sealed-battery alarms. Hardwired and certain connected systems have different rules. An older working alarm did not automatically become noncompliant on January 1, 2023; age, failure, installation and local rules matter.
Owners supply and install required alarms. Tenants test and maintain in-unit alarms and report uncorrectable problems in writing. Chicago guidance says replace smoke alarms at 10 years, including hardwired alarms.
