Fixed firefighting systems - Components for gas extinguishing systems - Part 3: Requirements and test methods for manual triggering and stop devices

This European standard specifies requirements and describes test methods for manual triggering and stop devices of CO2-, Inert Gas- or Halocarbon gas fire extinguishing systems.   Manual triggering devices allow a person to trigger the control device of the fire extinguishing system.   They are either non-electrical orelectrical devices.  Manual stop devices allow a person to initiate the emergency stop function of the electrical control device of the fire extinguishing system. Manual stop  devices are electrical components to operate the emergency stopfunction of the electrical control device of the fire extinguishing system.
