Smoke and carbon-monoxide alarms provide an early warning, but only when the correct devices are installed, maintained, and responded to. Property owners should follow device instructions, local requirements, and the building's fire-safety plan. A checklist does not replace required inspections by fire-protection professionals.
At each scheduled check
- Confirm the device is present, accessible, and not visibly damaged or covered.
- Use the manufacturer's test button or approved testing procedure.
- Record the device location, date, result, and any replacement or follow-up needed.
- Check expiration or replacement guidance in the device manual.
- Use the specified battery and device type; never disable an alarm to stop nuisance sounds.
Respond to an alarm promptly
If a carbon-monoxide alarm sounds, move everyone outdoors to fresh air and call emergency services or the local fire department from a safe location. Do not re-enter until responders say it is safe. Carbon monoxide cannot be seen or smelled. For a smoke alarm, follow the evacuation plan and call emergency services if there is fire or smoke.
Coordinate repairs responsibly
Repeated false alarms may result from placement, contamination, device age, or another condition. Do not remove the unit and leave it absent. Arrange an assessment and replacement with the appropriate qualified person. For interconnected systems, notify the responsible fire-alarm provider before any work that could affect operation.
Keep reliable records
Store alarm locations, test dates, service reports, and replacement records together. Tell residents how to report a chirp or damaged device and what to do in an emergency. Clear instructions and functioning alarms are essential parts of building safety.
