1. Intrusion alarm apparatus for a swimming pool comprising, in combination:
- first detector means for detecting mass and for providing a first output in response to the detector mass in the area of the swimming pool;
second detector means for detecting movement and for providing a second output in response to the detected movement in the area of the swimming pool;
logic means for receiving the first and second outputs and for providing a third output in response to the received first and second outputs;
keypad means, including a keypad adjacent to the swimming pool, for enabling the logic means to provide the third output in response to a first predetermined code and for preventing a logic means from providing the third output in response to a second predetermined code; and
first alarm means for receiving the third output and for providing at least a single alarm signal in response to the received third output.

Abstract
Intrusion detection apparatus for detecting the intrusion within a predetermined area utilizes two detectors, a microwave detector and an infrared detector for providing an ouptut signal indicative of intrusion when both detectors detect an intrusion. The system is controlled by a key pad having a predetermined code for both enabling and disabling the system. Different types of outputs may be provided, depending on the desires of the users of the apparatus.
