ABSTRACT:
A barking dog simulated alarm system which is activated by vibration of any doors or windows. A pre-recorded vicious dog sound is sounded which continues until the tape loop has been traversed and resumes when any portal is again disturbed. An alternative system is provided in which the barking sounds are switched back and forth between speakers at the end of each tape cycle. This makes the "dog" appear to move. The number of completed tape loops and therefore "dog" moves may be pre-determined.
