My client in has requested single-interlock pre-action systems be installed to protect each of their two communication / hub rooms in their new facility.
Space is limited in the facility and it was suggested to install a pre-action cabinet inside each of the rooms, thereby serving the room itself.
While a pre-action system cabinet/valve assembly cannot be installed in an area subject to freezing (application for cold/refrigerated storage) is there anything preventing the cabinet from being installed in the space it serves?
Due to dry pipe system size constraints and distance, it is not possible to locate the cabinets in the sprinkler room.

As long as it's a heated and lit space and complies with 184.108.40.206 and 7.3.2., I don't see a reason this is against code.

Installing a preaction valve assembly/control unit is permitted to be located within the room as noted in NFPA-13.

Totally allowable, but not the best choice. A riser room that has a very low fire load is the best place for a control assembly.

Not a problem to do it this way. And you're right, I would imagine that the riser room is a considerable distance and putting the P/A cabinets there will add to overall system dry capacity.

Late response due to traveling but still wanted to chime in on my experience.

Other than any local requirements not allowing this...

One item I'll throw in, while preaction systems are technically fire protection systems and typically have their own detection, typically heats, many AHJ's will want a building FA smoke detector above the preaction panel at as that panel is also considered FA control equipment. (Assuming conditions allow the smoke, if not a heat will suffice).

It is allowable to install the Pre-Action System Riser in the room that it is protecting. Need to ensure that access is maintained to the riser. Need to provide information to advise where supplemental risers are located within the facility.
