Smoke Alarm: A smoke alarm is a standalone device designed to detect the presence of smoke in a specific area. It is typically used in residential settings to warn early about a potential fire. Smoke alarms work by sensing smoke particles in the air and triggering an audible alarm to alert occupants of smoke.
Fire Alarm: A fire alarm system, on the other hand, is a more comprehensive and interconnected system designed to detect various fire-related events and provide comprehensive alerts and responses. Fire alarm systems are commonly used in commercial, industrial, and larger residential buildings.
In summary, while smoke alarms focus on detecting smoke particles and providing local audible alerts in residential settings, fire alarm systems are more comprehensive, interconnected systems designed to detect fire-related events, provide extensive signals throughout a building, and facilitate coordinated responses.
