
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. In addition, disable the logical
control function of the area or system to prevent false alarms.

Before maintaining the system, ensure that all control cables to solenoid valve drivers have
been disconnected. This prevents the agent release due to misoperations, and prevents
accidental damage. After the maintenance is complete, reconnect the solenoid valves and
inform the administrative departments that the fire extinguishing system has become
operational.
