Domestic fire sprinkler systems

Many of the fatalities and injuries caused by domestic fires could be prevented by the installation of a domestic fire sprinkler system. 

Copper tube to EN 1057 is the ideal material to use for the pipework.  Compared to the other pipework materials, copper has a smaller outside diameter and low friction losses.  It requires relatively few supports, being light and easy to handle and joint, especially in confined spaces.  Its excellent reliability and durability ensures that copper systems have a long trouble-free service life.

A wet pipe installation must be used, so the system is constantly charged with water, preferably direct from the mains.  Sprinkler system pipework must be sized such that it will deliver not less than 60 l/min through any single sprinkler and 42 l/min through any two sprinklers operating simultaneously in a single room.
