Supervisory Signals - Answer Signals which Indicate that a system or device being monitored has been compromised or is in an abnormal state. Will audibly and visually annunciate at the FACP to indicate the condition needs to be investigated and corrected. The FACP will also send a signal to an FDNY approved central station. Trouble Signals - Answer Battery failure, AC failure, ground fault, open or short circuit on a wire, phone line failure, internal component failure.
