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 .

When we use air circuit breaker, it has O/L protection ,time delay SC protection, Instataneous SC protection & ground fault protection. They all have some setting range. But what is the suitable/allowable setting for the above protection which will be safe for the equipment? For example-O/L protection setting have a range of (0.4,0.45,0.5,0.55,0.6,0.65,0.7,0.8,0.9,1.0)xIn Time delay SC protection have a range of (1.25,1.5,2,3,4,6,8,10,12)xIn Time delay setting is 0.02,0.1,0.2,0.3,0.4 Instataneous setting is fixed to 20xIn Gound fault setting is given 100A,300A,600A,900A,1200A This setting are for 2500A ACB. So what will be the basic allowable setting for the above protection? is there any formulae to calculate this<
