Provides recommendations for the planning, installation and servicing of electrical equipment for actuating of gaseous total flooding fire extinguishing systems. Describes the interface between the fire detection systems and fire extinguishing systems and also applies to fire protection systems for electronic data processing installations. Applicable only to electrically actuated total flooding gaseous fire extinguishing systems to be used in a temperate climate eg the United Kingdom.
