NFPA 72 Gets a Sound Upgrade: Introducing RAMO for Sensitive Occupancies
The National Fire Protection Association (NFPA) is constantly evolving its codes and standards to better protect people and property. In the proposed 2025 edition of NFPA 72, a significant new feature is emerging: Restricted Audible Mode Operation (RAMO) Notification.
What is RAMO?
RAMO is a new operational mode for fire alarm systems designed specifically for environments where loud sounds could be harmful or disruptive. This includes spaces like:
Early-education classrooms
Facilities serving individuals with autism spectrum disorder (ASD) or other sensory sensitivities
Areas where noise levels are already a concern
How Does it Work?
RAMO combines visual notification throughout the designated area with low-frequency audible signals at lower volume levels. This approach ensures that occupants receive clear alerts in the event of a fire without experiencing the discomfort or distress that standard alarms can cause for those with sensory sensitivities.
Why is RAMO Important?
This innovation is a significant step towards inclusivity in fire safety. By acknowledging the diverse needs of different populations, NFPA 72 is ensuring that fire alarm systems are effective for everyone.
For facilities like schools and healthcare centers, RAMO could significantly improve the overall emergency response experience, potentially reducing panic and confusion.
As a grandfather, I understand firsthand the needs of the target population for this new operational mode. Some of my own grandchildren fall into this category, and I am truly interested to see how RAMO is further developed and implemented in the future.
Proposed Requirements for RAMO in NFPA 72 (2025):
Clear Identification: RAMO areas must be clearly marked on project drawings.
Trained Staff: RAMO can only be used where trained, awake, and mobile staff are present to assist with evacuation.
Low-Frequency Sounds: Audible signals must be low-frequency (520 Hz ± 10 percent) and less distressing to sensitive individuals.
Visual Signals: All visual notification signals must be synchronized for maximum effectiveness.
Audible Signals: All audible notification signals must be synchronized.
These proposed requirements provide a framework for implementing RAMO safely and effectively, ensuring that everyone has the chance to respond to a fire alarm in a way that works best for them.
Looking Ahead:
The inclusion of RAMO in the upcoming NFPA 72 edition signals a broader trend towards more thoughtful, adaptable fire safety solutions. As we continue to learn more about the unique needs of different individuals and environments, it's crucial that our safety systems evolve alongside them.
