1. A supplemental alert generation device for supplementing an audible alert signal generated by a detector/alert device, the supplemental alert generation device comprising:

  • a threshold sound level detector operative to generate a notification signal when a monitored sound level exceeds a threshold sound level; and

    a controller that is responsive to the notification signal by transitioning out of a sleep mode into a signal analysis mode in which the controller determines whether a sound detected by the supplemental alert generation device is an audible alert signal, said controller programmed to initiate generation of a supplemental alert signal when said sound is determined to be an audible alert signal, said controller programmed to implement a learn mode in which the controller adjusts said threshold sound level based on a sound level of a detected alert signal, said learn mode thereby enabling the supplemental alert generation device to be paired, based on sound level, with the detector/alert device once the supplemental alert generation device has been mounted proximate to the detector/alert device.
