Which type of residential fire alarm system is most commonly found in homes without central monitoring?

• A. Central monitored
• B. Heat detector
• C. Single-station smoke alarm
• D. Photoelectric only

Answer: (C)

In homes without central monitoring, the typical fire alarm setup is a standalone system: a single-station smoke alarm that operates independently. Each unit has its own power source and its own audible alert, and while newer models can be interconnected to sound together, they don’t rely on a central monitoring service. This makes single-station smoke alarms the best fit for residences not connected to monitored systems.

The other options describe things that aren’t characteristic of homes without central monitoring. A central monitored system is connected to a monitoring service, which such homes don’t use. A heat detector responds primarily to high temperatures rather than smoke, so it isn’t the standard option for broad residential smoke detection. A device described as photoelectric only refers to sensing technology and doesn’t specify the overall system type, whereas the common setup in these homes is a standalone smoke alarm.
