ABSTRACT:
An alarm system having a signal evaluator is disclosed. The system includes an alarm controller and at least one sensor that generates a signal that corresponds to the magnitude of a detected event. The signal evaluator is part of the controller and receives the magnitude signal from the sensor. The signal evaluator compares the magnitude signal to an alarm threshold and generates an alarm signal if the magnitude signal exceeds the alarm threshold. If not, the signal evaluator compares the magnitude signal to a warning threshold and generates a warning signal if the magnitude signal exceeds the warning threshold and is less than the alarm threshold. The signal generated by the signal evaluator is coupled to an alarm annunciator which generates an alarm in response to the alarm signal and a warning in response to the warning signal. The warning and alarm may be vocal, a siren, or a chirp.
