4.5.5 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 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.
