What is the most common type of residential fire alarm system?

The most common type of residential fire alarm system is the single-station smoke alarm. This type of alarm is typically standalone, battery-operated, and designed to detect smoke and sound an alert locally. Single-station smoke alarms are widely used due to their simplicity, ease of installation, and affordability, making them accessible for most homeowners.

These alarms are effective in providing an early warning signal for smoke, allowing inhabitants to react quickly and evacuate in the event of a fire. They are often placed in key areas of the home, such as bedrooms and hallways, ensuring that the alarm will be heard in common living spaces.

While other systems like hardwired alarms or interconnected systems offer additional features and may help improve safety in larger homes or buildings, single-station smoke alarms remain the most prevalent choice for residential use due to their practicality and reliability.
