ABSTRACT:
A burglar alarm system includes an attack dog and is adapted for use in premises having valuable furnishings subject to damage when the dog becomes excited or incontinent. The system includes a dog kennel in the premises and auditory alarms in various zones which are distinguishable from each other by the dog. When an intruder is sensed by the circuit, one of the alarms sounds, the door of the kennel is unlatched and the dog dashes to the zone recognized. A locked box switch outside the premises is openable by firemen to open the circuit.
