What type of fire alarm system is typically used in large buildings?

In large buildings, addressable fire alarm systems are typically utilized due to their advanced capabilities in monitoring and maintenance. These systems allow for individual identification of devices throughout the facility, meaning that if an alarm is triggered, the exact location of the activated device can be determined quickly. This feature greatly enhances response times in emergencies, as firefighters and emergency services can go directly to the area of concern without having to search for the source of the alarm.

Addressable systems also provide additional benefits such as easier system management, flexibility for adding or removing devices, and more detailed information about system performance and potential issues. These aspects make them ideal for complex environments like large buildings, where multiple zones and various types of hazards need to be monitored cohesively. In contrast, conventional systems only categorize devices into zones and may require more time to identify specific issues, making them less suited for larger, more complex structures.
