What does a supervisory alarm do in a fire detection system?

A supervisory alarm in a fire detection system is designed to monitor the overall integrity and functionality of the system. It continuously checks for any conditions that could indicate a fault or malfunction, such as issues with wiring, power supply, or other critical components that could impact the system's performance. By keeping a vigilant watch, it ensures that the fire detection system is operational and ready to respond should a fire occur.

This monitoring aspect is essential for maintaining system reliability and safety, as it helps ensure that any potential issues are addressed before they can hinder the system's ability to detect and respond to a fire emergency effectively. Therefore, understanding the role of supervisory alarms is crucial for anyone involved in fire safety and prevention practices within facilities.
