Is there any direct reference to "Freezers or Coolers" in NFPA 72 that would reference Strobes or Horn Strobes requirements
As in not requireing them?
I would say you need to start with the building/ fire code for the project. That should dictate where a/v's should be located.
72 will just tell you how to install them.
Yes they have to be able to handle the environment.
So what is the real question??
The question came up as "Is there any requirement within the code that specifically references Freezers/Coolers as needing strobes or horn strobes installed in them". Most of the answers all refer to the AHJ having the discretion of needing them but only a few answers that show it either being referenced in ADA and not NFPA.
I would say start with the building code and fire code adopted.
If a system is needed, install at locations per the building and fire code.
Now, you kind of have a variable answer, you can have very small walk in coolers, to whole building coolers.
So in my opinion per the building and fire, notification devices would be required at some point depending on cooler size.
What that size is, may be an easy call or an ahj call.
But yes a/v's through out.
Generally speaking if you are required to install a fire alarm system, you will be required to provide occupant notification throughout the building including the storage areas.
In terms of he NFPA 101 Life Safety Code refer to the subsection _.3.4.3 of primary occupancy chapter plus the fundamental Section 9.6.2. The mandatory standard for the installation would be NFPA 72.
The requirements of the Life Safety Code are typically followed by the ICC codes, or they typically could be used as a basis for equivalencies to the ICC codes per the AHJ approvals.
Thank You Sir.
Where occupant notification is required, it must be distinct and clearly audible in all occupiable spaces. Chapter 7 of NFPA 72 contains criteria for the definition of Audible.
None of the codes and standards that I am aware of have specific requirements for walk-in coolers. The audibility becomes a problem from the sound attenuation of an insulated walk-in cooler or freezer. It may not possible to place alarm devices in common hallways and expect them to meet audibility requirements in adjacent spaces. In addition to audible appliances, the Life Safety Code might require visual appliances for occupant notification. Section 9.6.3 of NFPA 101 and Chapter 7 of NFPA 72 would then be consulted for the proper selection and placement of visual appliances to meet specific needs. This sometimes becomes the discretion of the designer.
I recommend consulting with the project architect/engineers via an request for information to help solve the problem of occupant notification in the walk-in coolers/freezers since most local AHJs legally can not provide design services.
