Abstract
A robust alarm system has an alarm controller adapted to input an alarm trigger and to generate at least one alarm drive signal in response. Alarm subsystems input the alarm drive signal and activate one or more of multiple alarms accordingly. A subsystem function signal provides feedback to the alarm controller as to alarm subsystem integrity. A malfunction indicator is output from the alarm controller in response to a failure within the alarm subsystems.
