7 This MALAYSIAN Standard cancels and replaces, Fixed firefighting systems - Automatic sprinkler systems - Design, installation and maintenance. Compliance with a MALAYSIAN Standard does not of itself confer immunity from legal obligations. For Public Comment13M003R1 STANDARDS MALAYSIA 2015 - All rights reserved v Introduction An automatic sprinkler system is designed to detect a fire and extinguish it with water in its early stages or hold the fire in check so that extinguishment can be completed by other means.

8 A sprinkler system consists of a water supply (or supplies) and one or more sprinkler installations; each installation consists of a set of installation main control valves and a pipe array fitted with sprinkler heads. The sprinkler heads are fitted at specified locations at the roof or ceiling, and where necessary between racks, below shelves, and in ovens or stoves. The main elements of a typical installation are shown in Figure 1.

9 Main elements of a sprinkler installation The sprinklers operate at predetermined temperatures to discharge water over the affected part of the area below. The flow of water through the alarm valve initiates a fire alarm. The operating temperature is generally selected to suit ambient temperature conditions. Only sprinklers in the vicinity of the fire, those which become sufficiently heated, operate. The sprinkler system is intended to extend throughout the premises with only limited exceptions.

10 In some life safety applications an authority might specify sprinkler protection only in certain designated areas and solely to maintain safe conditions for the evacuation of persons from the sprinkler protected areas. For Public Comment13M003R1 vi STANDARDS MALAYSIA 2015 - All rights reserved It should not be assumed that the provision of a sprinkler system entirely obviates the need for other means of fighting fires and it is important to consider the fire precautions in the premises as a whole.
