In the event of a short on a notification appliance Class A circuit, what signal is generated?

Explanation:
Class A circuits are supervised signaling paths, so any abnormal condition on the wiring is reported to the control panel as a fault. A short in such a circuit is a wiring fault that the panel detects, and it flags a trouble condition to alert that maintenance is needed. This is not an actual alarm (the devices aren’t actively calling in alarm), and it’s not a supervisory status (that term is reserved for specific monitored devices or conditions). It isn’t simply “normal” because the fault has to be addressed. So the signal generated is trouble.
