How Often Should You Test Smoke and Carbon Monoxide Alarms?
Test every smoke and carbon monoxide alarm at least once a month using its test button. Replace batteries and the complete alarm according to the manufacturer’s instructions, and replace any unit that fails a test or has reached its stated end-of-life date.

How do I test an alarm?
Warn household members, press and hold the test button, and confirm the alarm sounds. Follow the manual for interconnected and monitored systems.
Why is my alarm chirping?
A chirp may indicate a low battery, end of service life, a fault, or another manufacturer-specific condition. Check the label and manual.
Where should alarms be installed?
Placement depends on alarm type and local codes. Smoke alarms generally belong inside and outside sleeping areas and on every level; follow current local and manufacturer guidance.
When should the whole alarm be replaced?
Use the replacement interval printed on the alarm or in its manual. Replace it immediately if damaged or if it will not pass its test.
