What must a fixed automatic fire-extinguishing system with electrical power always be monitored by?

A fixed automatic fire-extinguishing system with electrical power must always be monitored by a supervisory alarm to ensure its proper functioning and readiness to respond in the event of a fire. The supervisory alarm serves as a critical safety feature that continuously checks the status of the system, including whether it is operational and whether there are any faults or malfunctions. This monitoring system alerts personnel to any issues that may prevent the extinguishing system from activating when required, thereby enhancing overall fire protection.

Supervisory alarms provide remote notifications, allowing for timely inspection and maintenance, which is essential for ensuring compliance with safety standards and protecting life and property. This proactive approach to monitoring helps ensure that the fire-extinguishing system is ready to perform its duty at a moment's notice, consolidating the reliability and effectiveness of fire safety measures within a facility.
