ABSTRACT:
A security system for pools and spas incorporates two distinct sections. The first control means allows for automatic operation and consists of sensors that detect and keep track of the number of adults entering or leaving the pool area and deactivate or activate the second control means of the system. Within the second control means, a motion detector first senses movement of an animate object in the area adjacent to the pool, which then interrupts, for a certain period of time, pool cleaning equipment to allow the aquatic sonic transducer to operate at a more effective sensitivity which senses frequencies characteristic of splashing over other sounds, coupled to circuitry responsive to the same frequencies. When splashing is detected, alarms are activated which then need to be reset.
