What defines an addressable fire alarm system?

• A. Each device has a name and location
• B. It uses only manual pull stations
• C. It uses a single control unit
• D. It cannot identify devices

Answer: (A)

An addressable fire alarm system is characterized by its use of uniquely identifiable devices that have specific names and locations programmed into the system. This feature enables the fire alarm control panel to pinpoint the exact location of a device that has been activated or is experiencing a fault. By knowing precisely which device has triggered the alarm, first responders can respond more effectively and quickly to incidents, enhancing overall safety.

The ability to identify each device individually stands in contrast to non-addressable systems, where devices are often connected in groups, making it difficult to determine the exact source of an alarm. The presence of unique identifiers—including names and physical locations—allows for better management and maintenance of the system as well.

In contrast, using only manual pull stations does not define an addressable system; it can include various types of automatic detection devices as well. A single control unit is a common feature in many alarm systems but does not specifically define an addressable system. Lastly, the inability to identify devices directly contradicts the core functionality of an addressable system, as its primary strength is this very ability.
