Firepump shutdown with only the possibility of manual restart

Hi, I was wondering if it is according to NFPA 20 or other relevant standards in Denmark that a firewater pump can shutdown on a platform if the remote Fire & Gas system detects gas or other ignition soruces in the area of the pump.


If the system gets an ESD trip signal the whole firewater pump system will shut down, with no possibility of automatic or remote start. Only a manual switch located outside the platform on the fire water pump area will turn the system on again. I couldn't find anything about it in the NFPA 20, only:


" Automatic shutdown shall be permitted only in the following circumstances:
 (1) During automatic testing in accordance with
 (2) Where approved by the authority having jurisdiction."


It seems a bit out of place that the fire system potentially could be not easily accessable when needed.
