● 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 the maintenance, disconnect all cables to fire cylinder electromagnetic
valves to avoid extinguishant release and damage to equipment due to
misoperations.
● After the maintenance, reconnect the cables to fire cylinder electromagnetic
valves and inform the administrative departments that the fire extinguishing
system has resumed.
