The invention discloses a pulse electric fence alarm system. The system comprises a main control panel, controllable high voltage generation apparatuses, a high voltage detection unit and a terminal module, wherein the controllable high voltage generation apparatuses are connected with the main control panel and high voltage metal alloy wires; under control of the main control panel, a high voltage pulse is generated to the high voltage metal alloy wires and each pair of high-voltage outputs are connected with a group of high voltage metal alloy wires; the high voltage detection unit is used to detect integrity of a high voltage signal and provide a basis for the main control panel to determine a pulse electric fence wire state; the terminal module is connected between ends of the each group of high voltage metal alloy wires, is used to match input impedance of the high voltage detection unit and output impedance of the controllable high voltage generation apparatuses and to provide anti-jumper impedance changes for the pulse electric fence alarm system so as to realize an anti-jumper function. By using the system of the invention, monitoring of short circuit and a clipping alarm signal can be realized, and the short circuit alarm can be achieved when the high voltage metal alloy wires are in a jumper state.
