Before conducting quarterly maintenance for the fire extinguishing system, notify the
related administrative departments that the fire extinguishing system will stop work during
the maintenance. 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 electromagnetic valve
drivers have been disconnected. This prevents the agent release due to misoperations, and
prevents accidental damage. After the maintenance is complete, reconnect the
electromagnetic valves and notify the administrative departments that the fire
extinguishing system has become operational.
