Abstract: A high security ultrasonic receiver apparatus including a rigid metal faceplate having an ultrasonic sensor affixed to the rear side thereof and adapted to sense acoustical energy transmitted to the faceplate. The faceplate has no apertures through which acoustical energy is intended to be communicated to the transducer. All acoustical energy is mechanically coupled to the transducer. The plate is further adapted to be affixed to a wall or wall receptacle in a manner similar to that of a standard electrical switchplate or plug socketplate. The transducer and associated electronic components are adapted to be electrically connected to a remote annunciator in a conventional manner.
