4.5.4 Fire Extinguishing System (Standard)
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.
