We are designing a new/upgraded fire alarm system for a remodeled highrise (our local codes are 2012 IBC and 2018 NFPA 1) and there is a detached walk-in cooler for the restaurant, located relatively close to the main building (~3' away from the nearest exterior wall).
We received an RFI asking whether fire alarm devices are required in the coolers - good question(!). I'm not able to find anything specific for fire alarm devices in detached storage buildings.
Do you see fire alarm required for the detached cooler?
If anyone has any insight (or NFPA references that I've overlooked), it would be very much appreciated!
Thanks for a great community!

I realize some will argue it needs occupant notification but IMO, no. Nor would it need sprinklers, IMO. I don't have a code reference stating its not required but I would not require it as an AHJ, its not part of the structure.

There are building design decisions that may require it be treated as part of the same building and therefor require sprinkler and notification.

I would think this would be required unless there is a rated separation between the two.

Work with the AHJ to determine the applicable requirements to be used. I am not seen any consistent for the independent annexes to these types of facilities.

This seems to come up every so often in a new building or panel migration/upgrade for buildings with walk-in coolers/freezers where I work. I believe the code does not support the installation of occupant notification inside of these storage spaces. People may use 101:188.8.131.52.1 as a pathway to support the installation of notification appliances in these spaces. These installations have also been a cause for system troubles from ground faults. This is usually caused from water getting trapped inside the weatherproof appliance. I don't think it is a good or necessary practice to install appliances that cause system troubles in an area that is not normally occupied.

I would be asking the architect is the high rise and this structure designed as two separate buildings* with an invisible lot line or one structure?
