Fire Sprinkler Systems in Surat

The only part of a fire system that acts without anybody being there

Everything else waits for a person. A sprinkler does not. Each head holds a glass bulb that bursts at a set temperature, and only the heads over the actual fire operate — which is the point people most often get wrong about sprinklers. A fire in one corner of a warehouse does not soak the whole building; it opens the two or three heads above it, usually while the fire is still small enough to be controlled.

Head types and where each goes

• Pendent heads hang down from the pipework and sit flush in a false ceiling. The standard choice for offices, hotels, hospitals, showrooms and retail floors.
• Upright heads sit above exposed pipework and throw the spray upward into a deflector. Used in warehouses, godowns and industrial sheds where there is no false ceiling.
• Sidewall heads mount on a wall and project outward, for corridors and narrow rooms where running pipework across the ceiling is impractical.

Temperature ratings and bulb colours

Sprinkler bulbs are colour-coded by their operating temperature, and the rating has to suit the normal conditions of the area. A head rated too low will operate on ordinary summer heat near a roof sheet or a kitchen; one rated too high will wait longer than it should. Selecting the rating for the space is part of laying the system out properly.

Layout, flexible drops and installation

Head spacing follows the ceiling type, the height, and what is stored underneath — racking in particular changes the picture, because stock stacked high blocks spray from reaching the lower levels. In false ceilings, flexible drop connectors make it far easier to align each head with the ceiling grid, and they save a great deal of rework when the grid layout changes late in a fit-out.

Sprinklers are normally fed from the same water supply and pump arrangement as the hydrant system, and are installed alongside detection and alarm so that the building is evacuated while the sprinklers hold the fire.
