4.5.4 Fire Extinguishing System (CE)

● Semi-annual maintenance of the fire extinguishing system involves system
commissioning. Before the maintenance, inform the related administrative
departments that the fire extinguishing system will be maintained and stop
working.
● Before maintaining the fire extinguishing system, remove the electrical actuator
from the container valve of the fire extinguisher cylinder. This prevents the
extinguishant release due to misoperations, and prevents accidental damage.
● After the maintenance, reconnect the electrical actuator, and inform the
administrative departments that the fire extinguishing system has become
operational.
