How does NFPA 72 address the installation of fire alarm systems in existing buildings?

The National Fire Alarm and Signaling Code, NFPA 72, recognizes that existing buildings may have legacy systems in place that do not fully comply with current codes. However, it emphasizes the importance of safety and the need for fire alarm systems to meet current standards to the greatest extent possible. This means that while there may be some limitations due to the existing structure, updates to fire alarm systems in these buildings should still strive to meet the latest code requirements.

By doing so, the goal is to enhance the overall safety of the occupants and property, ensuring that the fire alarm systems provide effective warnings and responses in the event of a fire. Compliance is not entirely waived; rather, it’s about balancing practical limitations with the need for safety upgrades. Therefore, existing installations must be assessed and modified as necessary to align with modern standards while considering the unique challenges presented by older structures.
