Supervisory signals are essential in fire alarm systems because they provide real-time feedback on the operational status and health of various components within the system. In the context of monitoring a fire pump, supervisory signals are generated for conditions that indicate that the system is functional but not necessarily in an alarm state. These conditions can include issues like low water levels, a fault in the power supply, or maintenance needs, which require attention but do not indicate an imminent threat.

When the system is monitored for these conditions, the supervisory signals alert personnel that while the pump is not in distress and is running properly, there are aspects that require investigation or intervention. This proactive monitoring ensures that the fire protection system remains reliable and effective, preventing potential issues before they escalate into alarms or failures. Therefore, understanding the role of supervisory signals is crucial for maintaining an effective fire alarm system and ensuring public safety.
