A Sprinkler is a device connected to a pressurized network of piping and contains a glass bulb with a special chemical in it.  Sprinklers are available at different ratings and operate at different temperatures.  When a fire takes place, the resultant heat causes the temperature of the chemical in the glass bulb to rise up and expand.  This causes the glass bulb to break and start a spray of water which covers a certain area below the sprinklers so that the fire is fought right when it starts.  The sprinkler network is connected to sprinkler pump, which is connected to a mechanical alaram that rings as soon as the fire pump starts.

The alaram rings the moment a single sprinkler operates,  thus warning the occupants of an outbreak of fire.   The electrical wiring is similar to the main fire pump. Sprinkler systems, by virtue of the fact that they are activated automatically as soon as a fire starts, prevent it's spreading further.  Thus the fire is localized and fought by the system without the help or assistance of occupants and is fully automatic.

As the provision of the hydrant / sprinkler system is to help the occupants fight the fire till such a time that the local fire authority reaches the premises, the fire authorities fight the fire using the system provided and the equipment brought by them.  The Fire tender consists of mobile water storage and associated pumping machinery should the premise's water storage get over.

A fire brigade collective breaching is provided on the underground static storage tank with instantaneous couplings mounted on them.  Water from the fire tenders can be off loaded to the under ground storage tank by means of hose pipes connected from the fire tender.

Fire brigade inlet connection is provided outside the building and near the riser, through a gate valve and a non - return valve.  The pumps of the fire tender can be connected to this inlet through which the water in the fire tender can be pumped up in the building to fight the fire.
