A fire hydrant is an active fire protection measure, and a source of water provided to assist in extinguishing a fire. It works effectively in improving the fire-fighting capacity of a place where it is installed. And an automatic sprinkler system is intended to detect, control and extinguish a fire, and warn the occupants of the occurrence of fire. The installation comprises fire pumps, water storage tanks, control valve sets, sprinkler heads, flow-switches, pressure switches, pipework, and valves. The system operates automatically without human intervention.
