Communications	Encoded 484.84 kHz tone inductively coupled into the string PV+ lineDocumented claim Conditions Printed as "The transmitter generates a signal which is inductively coupled into the string PV+ line. The signal consists of an encoded 484.84 kHz tone." The receiver connects the string when it detects a valid signal and shuts off 5 seconds after the signal goes away (page 1); page 7 says the receiver opens the circuit within a few seconds of the signal being interrupted.
