The frames types depends on the areas that should be covered, type of hazard to be protected and the visual effects that may be required. Thermal linkage controls the release of water from the sprinkler systems. The linkages hold the cap in the right place and prevent water from flowing out of the pipes. (Wallace, and Webber, 2004, p. 285).
The function of the cap is to provide the water tight seals over the sprinkler orifices that are held in place by the thermal links. In case the thermal fails to function, the cap is released and water finally flows from the orifice. Orifice refers to the opening in the water pipes at the base of the sprinkler valve. The opening in the water pipe is at a place where the water comes from which is about half an inch in diameter .It varies from the larger hazardous areas to smaller ones in the sprinklers systems. The detector is used in splattering the water streams from orifice to the pattern that is efficient for suppression of fires (Wallace, and Webber, 2004, p. 285).
It is therefore important for all organizations to install the sprinklers systems within their organizations so as to protect themselves as well as their organizations from fires.
