a device or alarm that starts beeping if it detects smoke or fire
A smoke alarm is a safety device that detects smoke in the air and sounds an alarm to alert people of a potential fire. It works by using sensors to detect smoke particles, triggering a loud noise when smoke is present. Smoke alarms are commonly installed in homes and buildings, typically in hallways or near bedrooms, to provide early warning in case of a fire. Many smoke alarms also include a built-in battery, ensuring they remain functional even during power outages. Regular testing and maintenance of smoke alarms are important for ensuring safety.
