This part of BS 7273 gives recommendations for the design, installation and commissioning of electrical actuation arrangements for pre-action watermist and sprinkler systems. It covers the interface between fire detection and fire alarm systems (see BS 5839-1), sprinkler systems (see BS EN 12845) and watermist systems1). This part of BS 7273 does not apply to the interface with sprinkler systems designed in accordance with BS 9251.
Recommendations relating to watermist systems which do not operate in the pre-action mode are contained in BS 7273-5.
NOTE Watermist systems can be used for the suppression, control and extinguishing of fires. In this part of BS 7273, the references to fire extinguishing systems relate to watermist systems of any type, as well as to sprinkler systems.
