NFPA 72 2025 Edition Update

NFPA 72 2025 Edition Update for Building Fire Protection

Fire safety is paramount for commercial property owners and managers. Adhering to the latest standards, such as the 2025 edition of NFPA 72, the National Fire Alarm and Signaling Code, is crucial for ensuring the safety of occupants and compliance with regulations. 

The NFPA 72 2025 edition introduces significant changes designed to improve building fire protection systems, enhance occupant safety, and integrate advancements in technology. While some Authorities Having Jurisdiction (AHJs) may still reference older codes, proactively updating your systems to align with the newest edition demonstrates a commitment to safety and positions your business ahead of regulatory changes.

Key Changes in the 2025 Edition of NFPA 72

1. Introduction of Restricted Audible Mode Operation (RAMO)

Referenced Code: NFPA 72 (2025), Section 18.4.1.7

The 2025 edition introduces a new notification scheme called Restricted Audible Mode Operation (RAMO). This allows lower sound pressure levels in environments where loud sounds could cause distress, such as classrooms for young children or facilities serving individuals with sensory sensitivities. Visual notifications remain unchanged, and RAMO requires a risk analysis and approval by the AHJ.

What’s Different?
Previously, notification appliance standards focused on ensuring maximum audibility, but RAMO offers flexibility for environments where traditional noise levels might be inappropriate.

• Why It Matters: RAMO helps tailor fire alarm systems to meet the unique needs of specific occupants while maintaining overall safety compliance.

2. Enhanced Cybersecurity Requirements

Referenced Code: NFPA 72 (2025), Chapter 11

The expanded cybersecurity guidelines categorize network-connectable equipment into security levels, from non-IP-wired interfaces to publicly accessible networked systems. Systems without internet connectivity or remote access are exempt from these requirements.

What’s Different?
Cybersecurity was first introduced in the 2022 edition, but the 2025 update provides more detailed requirements, making it easier to evaluate and implement security measures.

• Why It Matters: Safeguarding fire alarm systems against cyber threats ensures uninterrupted functionality and data integrity.

3. Clarification on Smoke Detector Testing

Referenced Code: NFPA 72 (2025), Section 14.4.5

Magnets are no longer acceptable for functional testing of smoke detectors. Testing must now ensure that smoke enters the sensing chamber using actual smoke or a manufacturer-approved listed product.

What’s Different?
Earlier editions allowed magnets for functional testing, but this update emphasizes testing the actual performance of smoke detectors in real-world conditions.

• Why It Matters: Proper testing ensures the effectiveness of smoke detectors, critical for early fire detection and occupant safety.

4. Battery Requirements and Maintenance

Referenced Code: NFPA 72 (2025), Section 10.6.7

All rechargeable batteries used as secondary power sources must be listed by a nationally recognized testing laboratory. During inspections, batteries must retain at least 60% of their shelf life based on the manufacturer’s expiration date.

What’s Different?
Battery standards were present in previous editions, but the 2025 update adds stricter criteria for shelf life and testing to improve system reliability.

• Why It Matters: These updates ensure dependable backup power during emergencies, maintaining the functionality of fire alarm systems.

5. Clarification on Abandoned Equipment

Referenced Code: NFPA 72 (2025), Section 10.5.1.2

Abandoned fire alarm equipment must either be removed or clearly labeled as “not in service.” This avoids confusion and ensures that only active components are in use.

What’s Different?
The clarification addresses practical issues on sites where unused equipment might remain installed, reducing the risk of miscommunication during emergencies.

• Why It Matters: Clear handling of abandoned equipment ensures smooth operation and effective fire alarm management.

6. New Detection Technologies:

o   Acoustic Leak Detectors: New standards for detecting pressurized gas leaks via sound.

o   Thermal Image Fire Detectors: Specific requirements added to address the unique characteristics of thermal imaging for fire detection.

7. Smoke Detector Spacing: 

Clarifies that standard spacing remains unchanged for ceilings up to 40 feet (12.2 m), beyond which performance-based design is required.

8. Fuel Gas Detection: 

Chapter 29 now directs users to NFPA 715 for fuel gas detection and warning equipment standards.

9. Intermediary Service Provider

Finally, requirements for a new technology known as an Intermediary Service Provider have been proposed for the code. 

This technology has been developed and is being used to transmit signals from a protected premises to a supervising station. This technology serves as a gateway between a protected premises and the supervising station that intercepts signals and allows signals to be sent to other entities in addition to the supervising station, such as facility managers or building owners for business purposes. An example of this arrangement can be seen in the diagram below. The new requirements are proposed for Chapter 26 to ensure that these signals are processed in a reliable and supervised manner and do not bypass the supervising station. 

As mentioned, these are still proposed changes, but they offer some insight into the types of emerging technologies and other changes that are being incorporated into the next edition of NFPA 72.

Proactive Compliance: Why It’s Essential

Even if your local AHJ has not yet adopted the 2025 edition of NFPA 72, proactively updating your fire alarm systems to meet these standards offers several benefits:

• Enhanced Safety: Implementing the latest safety measures protects occupants and property.
• Regulatory Preparedness: Staying ahead of code adoption ensures a smoother transition when new regulations are enforced.
• Demonstrated Commitment: Aligning with the latest standards showcases your dedication to safety and compliance, building trust with clients and stakeholders.
