ABSTRACT:
An automatic alerting apparatus and method, is herein disclosed, which audibly signals neighbors when a house or building door has not been opened in the previous twenty-four (24) hours. The system comprises a plurality of contacts aligned in a parallel connection on the exterior doors of a residence. The contacts are connected to a resettable twenty-four (24) hour timer. In use, if the timer is not rest in a twenty-four (24) hour period then power is supplied to an audible horn or beacon which alerts others to a potential emergency situation. It is envisioned that the device apparatus would have a back-up battery system for use during power failures and an override button for periods where no one will be in the residence for more than twenty-four (24) hours.
