ABSTRACT:
An animal containment system is disclosed wherein the contained animal wears a receiver which receives first and second codes in the form of frequencies which are defined in adjacent curtains of near infrared or the like light established by a transmitting device. One pair of one shots detects one frequency and a second pair of one shots detects a second frequency. When the warning frequency is detected a sounder continuously operates and when the second frequency is detected a transformer is intermittently operated to shock the animal and the sounder is intermittently operated. The transformer can be operated in three modes: high power, low power or disconnected.
