A smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial smoke detectors issue a signal to a fire alarm control panel as part of a fire alarm system, while household smoke detectors, which are typically battery-powered, generally issue a loud audible alarm from the detector itself. Smoke detectors are typically used in homes, offices, and other buildings to alert people to the presence of smoke, allowing them to evacuate the building and summon help.
Smoke detectors can be a crucial part of a fire safety plan, providing early warning of a potential fire and giving people time to escape. Smoke detectors have been credited with saving many lives, and they are an essential part of any home safety plan.
