Overview

The water discharged from the sprinkler is distributed by the deflector over the location of the fire. The area protected by each sprinkler is determined by the hazard and can vary from 9m2 to 21m2. The selection of the deflector is based upon the specific application, its upright or pendent position within the sprinkler distribution pipework and its spray pattern.

Sprinklers are manufactured with three different connection sizes (10, 15 and 20mm) which have different water outputs (57, 80 and 115litres/minute respectively) at a flow pressure of 1 bar. The sprinkler bulb is designed to operate at a predetermined temperature. A range of operating temperature ratings is available from between 57 – 182 degrees Centigrade.

Conventional sprinklers

These can be mounted in either the upright or the pendent position and the deflector is designed to spray a proportion of the water discharge on to the surface of the ceilings.

Upright and pendent spray sprinklers

Spray sprinklers are used for applications where all the water needs to be discharged downwards.

Sidewall sprinklers

These are primarily used to keep ceilings clear of pipework for aesthetic reasons or to avoid having to disturb existing ceilings when installing pipework. Each sprinkler protects up to 17m2 in light hazards and 9m2 in ordinary hazards.

Horizontal sidewall sprinklers with extended coverage

These are specifically designed to give an extended coverage of water distribution.  This type of sprinkler must have a fast response bulb.  One sprinkler can protect an area of up to 21m2.

Fast response sprinklers for life safety

In a fire, few deaths result from direct contact with flames.  The greatest threat comes from inhalation of the products of combustion such as carbon dioxide, carbon monoxide, hydrogen cyanide, hydrogen chloride and other toxic gases, and the heat of the gases.

The response time of a fast response sprinkler ensures that the life threatening level of toxic gases and temperature are never reached. There are people who cannot escape by their own efforts, such as in hospitals or homes for the aged, and sprinklers provide valuable time for those in charge to assist their escape.
