Description: L, R, should all is AC load output by R3, R4, C2, C3, into the earth, AC-to-ground short circuit, DC signal if all the way with DC component will be generated in the resistor-capacitor node or a positive or negative voltage via a diode bridge, the whole into a DC, Q1 turns on when the voltage exceeds a diode forward voltage and Q1 conduction voltage, Q2, and Q3 is turned off, the relay release, play a particular channel is not normally protected. This circuit also start delay protection: Power voltage by R2 to C4 charge voltage slowly rising voltage reaches D8, Q2, Q3 conduction voltage and relay. Load to reach-delay
