Which signals are reported to authorities by Supervising Station Alarm Systems?

• A. Supervisory signals
• B. Trouble signals
• C. Fire alarm signals
• D. All of the above

Answer: (D)

A Supervising Station Alarm System is designed to relay any conditions that affect life safety and system reliability to the authorities. When a fire alarm is triggered, that signal is transmitted and reported. Supervisory signals, which indicate non-normal conditions in the protected system (such as a monitored valve or a sprinkler system component that needs attention), are also reported so responders know there’s an issue that could affect protection. Trouble signals, signaling faults within the alarm and monitoring network itself (like power or communication problems), are reported to ensure the system’s integrity is understood and addressed. Because this type of system is built to forward all three kinds of signals to the appropriate authorities, all of the above are reported.
