Recommended for you

Your sprinkler temp. rating should be at least more than 28C, 50F than the maximum anticipated room temperature.
 
I would use 286 Deg.

2019 Edition NFPA 20 Handbook Commentary said:
Sprinkler plans show the protection criteria for the pump room with a diesel engine–driven pump based on Ordinary Hazard Group 2. Is this protection criteria acceptable?

ANSWER: No. The fire pump room that houses a diesel engine–driven fire pump will also include a dieselfuel supply. Since the presence of this fuel is considered storage of a combustible liquid, the protection criteria is required to be Extra Hazard Group 2

11.3.3 The entire pump room shall be protected with fire sprinklers in accordance with NFPA 13, Standard for the Installation of Sprinkler Systems, as an Extra Hazard Group 2 space.
 
where are you?

NFPA is for the USA. different regulations apply elsewhere on the planet
