Presentation title - 26/06/2014 P 8 ACTIVE FIRE PROTECTION SYSTEM High Velocity Water (HVW) Spray system, High Velocity water spray systems are installed to extinguish fires involving liquids with flash points of 65 deg C (150 deg F) or higher. Three principles of extinguishment are employed in the system - emulsification, cooling and smothering. The result of applying these principles is to extinguish the fire within a few seconds. HVW spray system shall be provided with two (2) separate pipe networks. One, a detection pipe network over the protected equipment with heat sensing detectors located at strategic locations. Other will be the fire water pipe network spread over the protected equipment, provided with water spray nozzles located at suitable points to spray water on to the equipment in case of fire. In case of fire, the valve opens automatically & releases the water from header to ring mains & then sprayed on the protected equipment. Quartzoid bulb (QB) detectors are the sensing devices which sense the fire . In case of fire, these bulb breaks causing pressure drop in the wet detection line of the system which opens the DV: Equipment Protected : Oil filled Transformer, Generator, OPU Lube Oil / Insulating Oil Fixed tank 9.

Presentation title - 26/06/2014 P 14 ACTIVE FIRE PROTECTION SYSTEM CLEAN AGENT (GASEOUS FIRE SUPPRESSION SYSTEM) Clean Agent fire suppression systems are used in enclosures where a sprinkler system would cause damage to sensitive contents such as computer servers, paper files. Upon fire detection the compressed Clean Agent, which can be a halocarbon or an inert gas, is released into the enclosure causing a Peak Pressure of around 5 to 25 pounds per square foot to occur for a fraction of a second. Once the enclosure is totally flooded, the agent will begin to leak out at a rate that primarily depends upon leakage area in the lower part of the enclosure. 15. ALSTOM 2013. All rights reserved.

Presentation title - 26/06/2014 P 50 Spacing of fire detectors : A smoke detector under a flat ceiling has a radius of 7.5 metres. Heat detectors have a radius of 5.3 metres. A detector radius should reach every part of the room. Detectors should be located a minimum 500mm away from walls. There should be a 500mm clear space below and around the detector. Detectors should be located at least 1 meter from air conditioning units. If an obstacle eg. (beam/RSJ) is less than 10% of the ceiling height then ignore. If it is more than 10% of the ceiling height, treat it as a wall for detector spacing locations. Obstructions from floor to ceiling is more than 300mm ignore, less than 300mm then treat as a dividing wall. 35 to 40 sq.m per detector for general application. 20 to 25 sq. m per detector for main control room, electronic cubicle room etc. FIRE DETECTION SYSTEM INPUT 51.
