NFPA 72 & UL 2572

Day to day, building codes exist to keep us safe and to ensure good communication practices. In considering our Mass Notification Emergency Communication systems (MNEC), the intersection of building codes with fire detection and intelligent notification equipment is a positive way of ensuring safety. 

The National Fire Protection Association (NFPA) is the governing code body devoted to eliminating death, injury, property and economic loss due to fire, electrical and related hazards. One of the codes, NFPA 72: Fire Alarm and Signaling, specifically addresses mass notification systems. Beginning in 2010, the National Fire Protection Association (NFPA) revised their code "72" to include “Signaling” as a comprehensive means to incorporate all emergency communications as part of it. The code has been reinforced with the 2013 and 2016 additions inclusive of refined language and furthered development. NFPA 72 2010 established the parameters and requirements necessary to effectively communicate in the event of a fire, weather, or human-related threat.

Highlights from NFPA 72 include the establishment of combination systems, equipment performance, supervision and inter-connectivity of systems, shut down of ambient noise, and emergency communications requirements.



The ADA ensures access to the built environment for people with disabilities. The ADA Standards establish design requirements for the construction and alteration of facilities subject to the law. These enforceable standards apply to places of public accommodation, commercial facilities, and state and local government facilities. 

Underwriters Laboratories (UL) is a safety consulting and certification company focused on the establishment of safety standards for electrical devices and components. Since NFPA 72 Chapter 24 permits the interconnection of Life Safety equipment with other nonperformance based systems, UL2572 provides requirements as well as guidance on how this can be achieved without impacting the integrity of a certified Life Safety system.

The n.FORM and i.Net Rack Mounted System Solutions are built to interface with a Fire Alarm Control Panel (FACP) in order to reinforce the fire alarm annunciation as well as take control and shutdown the sound masking in a non-fire emergency. Achieving the UL 2572 standard is positive proof that the n.FORM and i.Net system solutions are engineered to perform at the highest levels.
