Smoke & Carbon Monoxide Detector FAQs

Protect your family with properly installed smoke and carbon monoxide detectors throughout your home.

Every 7–10 years, or sooner if malfunctioning.

Yes — with battery backups for constant protection.

Yes — when one sounds, all alarms in your home alert simultaneously.

Smoke detectors warn you of fire or smoke, while CO detectors alert you to dangerous carbon monoxide gas, which is colorless and odorless and can be lethal without detection. Both are essential for comprehensive home safety.
Detectors should be installed on every level of your home, inside and outside sleeping areas, and near fuel-burning appliances. Proper ceiling or high wall placement ensures early detection.
While battery-powered models can be installed by homeowners, hardwired detectors or multiple interconnected units should be installed by a licensed electrician to meet local electrical and building codes and ensure reliable operation.
Hardwired detectors are connected directly to your home’s electrical system and typically include battery backup for power outages, while battery-powered models rely solely on replaceable or sealed batteries.
You should test detectors at least once a month and replace batteries at least twice a year (for models with replaceable batteries). Cleaning dust and debris from sensors also helps prevent false alarms.
You can choose stand-alone smoke and CO detectors or combination units that detect both hazards in one device. Modern smart detectors may also offer features like mobile alerts or integration with home automation systems.
If a smoke detector sounds, evacuate immediately and call 911. For a CO alarm, leave the home right away and seek fresh air — then contact emergency services and have the source of CO investigated.
