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: - automatic fire detection installation - electrical control device - non-electrical special fire detector - manual triggering device or - 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.
