S-95 Fire Alarm Systems Practice Exam 2025 – Comprehensive Test Prep

In commercial buildings, the primary types of fire alarm systems installed are addressable systems and conventional systems.

Addressable systems allow for the identification of the specific location of a fire or fault within the system due to each device being assigned a unique address. This feature provides precise information during an emergency, enabling a more effective response from fire departments and building personnel. These systems can also offer advanced monitoring capabilities, simplifying maintenance and troubleshooting processes.

Conventional systems, on the other hand, operate using zones, where multiple devices are connected to a single circuit. When an alarm is triggered, the control panel indicates which zone is activated, but it does not provide the exact location of the individual device that initiated the alarm. While they are typically less sophisticated than addressable systems, they can still be effective for buildings where budgets are a concern or where the design is relatively simple.

The focus on these two types highlights their practical application and reliability in commercial settings, as they encompass a range of features suitable for ensuring safety and compliance with fire codes.
