3.6.4 Fire Extinguishing System (CE)
Semi-annual maintenance of the fire extinguishing system involves system commissioning.
Before the maintenance, inform the related administrative departments of the temporary
downtime of the fire extinguishing system. In addition, remove the cable connected to the
2ND STAGE NO
terminal on the extinguishant control panel to disable the linkage
control function. After the maintenance is complete, reconnect the cable to the
2ND
STAGE NO
terminal on the extinguishant control panel to enable the linkage control
function, and inform the administrative departments that the system has become
operational.
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.
