Which of the following statements is true about addressable fire alarm systems?

• A. They group devices into zones and report zone-level alarms only.
• B. They assign a unique address to each device, enabling reporting of exact device location/status to the panel.
• C. They require no panel for operation.
• D. They do not support monitoring device status.

Answer: (B)

Addressable fire alarm systems assign a unique address to each device, allowing the control panel to report the exact location and current status of that device. This means when a detector, pull station, or other device changes state, the panel can identify exactly which device it is and what its condition is (alarm, fault, normal, etc.). This pinpointing capability improves response time and maintenance because you don’t have to guess which device is involved.

In contrast, systems that are not addressable organize devices into zones and report alarms at the zone level, so you only know that something in a zone happened, not which specific device.

Addressable systems still require a control panel to coordinate and display information, and they do monitor device status rather than just signaling that an alarm occurred.
