This European Standard specifies requirements and test methods for non-electrical automatic control devices incorporating non-electrical delay devices for CO2, inert gas- or halo-carbon-gas fire extinguishing systems. This European Standard applies to devices which may be triggered by: - an automatic fire detection installation - an electrical control device - a non-electrical special fire detector - a manual triggering device or - a combination of the above. Where applicable the requirements and test methods also apply to separate non-electrical delay devices. This European Standard covers devices which are powered pneumatically, mechanically or by a combination of both.
