If it is a alarm ,as a member of ERT or Maintenance/management team,We should first analyse whether it is Real or false alarm by checking the fault zone indicated in the FA panel .It could be false alarm due to dust collection in detector or some other reason ,such case follow your organisation procedure and reset it ,'
If its a real fire and alarm ,do the possibility with you like if we are ERT member or trained ,inform first your seniors and Paralaly try to extinguish the fire with Extinguisher/Hydrant system and also switch OFF the Power supply . Operate the MCP ,so others you can make alert and announce in PA system about the fire and to Evacuate the Building .
If you are not having any knowledge of Fire system ,first you evacuate the building and inform management for the proper action .
