I would highly recommend that you look into water mist fire
suppression. It uses 10% as much water as normal sprinklers and has
properties similar to a gas in that fine water particles are able
get into small cracks and crevices within a room. In addition, the
piping is flexible and takes up less space than a conventional
sprinkler system.

Gas suppression only works well in very tight, sealed rooms with low
ceilings that do not normally have windows and doors open to other
rooms or to outside spaces. Inergen (a mixture of inert gasses) is
usually preferred by most fire suppression specialists due to its low
toxicity and relatively good fire suppression characteristics.

I recently did a research project on this topic and would recommend
the following resources:
