If a smoke alarm is old, missing a readable date, chirping, damaged, painted over, or failing the test button, renters should report it to the landlord or property manager. Do not disable smoke alarms because of nuisance alerts.

Smoke alarm replacement FAQ
Should I replace an alarm with no date?
If the date is missing or unreadable, ask the landlord or manufacturer for guidance. Missing date information is a good reason to document and follow up.
Can I remove a hardwired smoke alarm to check the date?
Do not remove hardwired alarms unless you are allowed and it is safe. Ask the landlord or property manager instead.
What if the alarm keeps chirping?
Do not ignore it or disable it. Follow the instructions and report ongoing chirping if it does not resolve.
