You will not be using CO2 or Dry Chemical in a potentially occupied room. Scratch those off the list.
NOVEC 1230 is becoming a more environmentally friendly choice. I have also seen Argonite (IG55) becoming another viable option replacing FM-200. I've never seen CAF used for electrical rooms, too much equipment to maintain plus not many trained on the upkeep of these systems. Applicability is questionable. Wet pipe automatic sprinklers probably come in #2 right behind SIPA. SIPA gets used a lot due to Electrical engineers spazzing over the concept of wet pipe water based sprinklers "accidentally going off over their equipment and electrocuting people". I have less issues with owners having concerns over wet pipe sprinklers in electrical installations than I do electrical engineers who base their presumptions on old Saturday morning loony toons. I will not go DIPA for electrical rooms, it's gross overkill with no practical advantage and actually creates a disadvantaged protection scheme. If there's a fire in an electrical installation and sprinklers don't put it out, fire hoses will. The longer you delay action by the sprinkler system, the greater the extent of the damage. I was in a team meeting with a client when the discussion of fire sprinklers in electrical rooms came up. One EE was vehemently opposed to the idea and exclaimed "what is there to burn in an electrical room, there's no chance of a fire!" One of the site maintenance people chimed in, "oh, but don't you remember that fire we had in electrical room 123?" Greatest fire protection moment ever! Little UPS or PC based "server" rooms often don't warrant the cost of a special system and should just be protected as you would the surrounding areas. Whether required by code or not, it's not a bad idea to place a smoke detector in a server closet to provide an early warning of an upset condition to allow for manual intervention before it becomes a fire.

Your comments will be used to create a more effective and greener design. What are some experiences with successes of automatic fire suppression (not experiences with "I have been doing it this way for 30 years" [1] ) in battery power storage rooms? Automatic fire suppression successes in battery storage rooms with agent: a. wet pipe standard spray sprinkler b. dry chemical c. CO2, d. other alleged "clean" agent, but hologenated gases; e. wet pipe water mist sprinkler, f. CAF, g. other. Here is a facility where fire broke First Wind on 3 separate occassions[2]. After the 3rd go, design migrated away from battery storage and is now using dynamic reactive-power to modulate eccentricities in power generation.
