What is a common type of residential fire alarm system?

• A. X-10 detector
• B. Single station smoke alarm
• C. Remote-reporting heat detector
• D. Sprinkler system

Answer: (B)

In homes, the most common fire alarm setup is a single station smoke alarm. This is a self-contained device that detects smoke and sounds its own alarm locally, without needing a central monitoring system. It can be powered by batteries or be hardwired into the house’s electrical system with a backup battery. This type is popular because it’s affordable, easy to install, and provides immediate warning in the area where smoke is detected. The other options describe systems that are less typical for ordinary residences: X-10 detectors use power-line communication to a remote receiver and aren’t commonly used today; remote-reporting heat detectors are part of monitored systems that alert a central station, more common in larger or specially protected homes; sprinkler systems aren’t fire alarm devices but extinguishing systems, so they aren’t the typical residential fire alarm.
