While the purpose of a fire alarm system is to evacuate the building safely in the event of a fire, a mass notification system (MNS).
The system is designed to keep occupants informed of the type of emergency and direct them on what to do and where to go. However, they share a common goal to warn people of danger and provide information to stay safe.
NFPA 72 code
For this reason, the NFPA 72 code recommends the use of a single integrated combination Emergency Communication System (ECS). FPS control panels comply with NFPA 72 and are also designed to meet the combined system requirements as outlined in the proposed UL 2572 Standard.
Because these systems combine fire alarm and mass notification systems, they offer substantial cost savings advantages. Following the new standards allows for better coordination of the system's functions. These functions are vital in minimizing confusion and panic during emergency conditions.
