From the 2023 Edition of NFPA 855, Section 14.6.4 "Outdoor storage areas with an aggregate area greater than 400 sqft (37.1 sqm) shall be provided with a fire alarm system activated by a radiant-energy detection system with occupant notification installed in accordance with NFPA 72."
How do you interpret this requirement if there is outdoor storage of Li-Ion batteries without any sort of structure and 300' from any building, and there are no occupants to notify? Thanks for your help! Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe

If it's 300' away from any building/structure, no need to provide a canopy just to be able to install a smoke detection system.

One interpretation: Install Weatherproof/explosion-proof UV/IR detection; Install Weatherproof/explosion-proof Horn or Horn-strobe to alert anyone who may enter the protected area at any given time; sending an Alarm Condition to a constantly-attended location.

Radiant heat energy doesn't need a building to transmit heat. Much like standing 30-ft from a bon-fire and feeling the heat. And while there may be no occupants, the intention is to solicit an emergency response.

I would assume there has to be some person near this business that would be in charge. If this is a stand-alone storage area with no office or building associated with it, I would contact your AHJ for clarification. NFPA is always the minimum requirements for fire life safety, that is why its the standard and not the code. AHJ will probably be your best bet since your scenario does not represent conditions within the standard.

The code section is very clear, of outside storage:

Again 72 is a standard IF another code, adopted, requires it. 855 doesn't require any FA system, but IF on existed then here's what to do. If there is no FA system then no detection regardless the size.

Flame Detectors coverage is based on a Field of view or cone of vision of battery the plum of radiant energy. The flame detectors placed atop poles spaced accordingly. The FACP supervises the detector for alarm, supervisory and trouble conditions, As well as is able to provide the battery back up and alert the responsible party of and event caused by the system. Occupant notification is usually an exterior weatherproof device at the entrance or in the building control room if there is such a building. A lot of this would require a performance based approach.
