Smoke alarms, carbon monoxide alarms & fire-safety planning

Respond to an alarm before planning electrical work

If a smoke or carbon monoxide alarm sounds, get everyone outside to a safe location and call 911. Follow emergency responders' instructions before returning. A website inquiry, phone notification or service estimate is not a substitute for responding to an active alarm.

Match the alarm to the hazard and the existing system

Smoke alarms and carbon monoxide alarms detect different hazards. A combination unit includes both functions; the word smart describes additional features and does not establish the right coverage for your property.

A hardwired replacement needs to match the electrical supply and any interconnected alarms. A connector that appears to fit does not prove compatibility. Record the existing model and age from information you can safely access, and have the installation assessed without opening electrical connections yourself.

Include testing, backup power and replacement planning

USFA recommends monthly smoke-alarm testing and generally replacing household smoke alarms at ten years; follow the actual model's instructions. Carbon monoxide alarms have their own replacement and end-of-life instructions. Do not assume that every sensor shares a ten-year service life.

Chirps and fault messages have model-specific meanings. Keep protection in service and follow the manufacturer's instructions rather than disconnecting an alarm to stop a sound. For uncertainty about a possible emergency, leave and seek emergency help.

• Confirm suitable locations, audibility and any accessibility needs with the installation professional.
• Include required backup power, compatible interconnection and the manufacturer's functional checks in the scope.
• Smart alerts depend on the product and its communications; they do not replace working local alarms or an escape plan.

A building fire-alarm system is a separate design

Commercial fire-alarm systems can include a control panel, system detectors and notification appliances such as horns or strobes. Household alarms cannot simply be substituted for those devices. Approved plans, listed compatibility, local requirements and the responsible system specialists determine the work and ongoing testing.
