The extension telephone electric circuit is carries on the monitoring to the scene, once has the intruder, the extension telephone on to the main engine launch alarm. In this design extension telephone electric circuit most has 15 groups, the extension telephone electric circuit has two compositions ways: The heat releases the infrared sensor extension telephone electric circuit, does spring pipe the magnetism to control the sensor extension telephone electric circuit. The main engine duty mainly is the half machine launch alarm carries on the receive, processing, instructed the police sentiment occurs the place and sends out reports to the police the sound. When in the power circuit design, the extension telephone uses the battery power supply, the main engine uses the alternating current supply and the battery carries on the replace power supply, the alternating current supply power cut, power source automatic cut over for battery po
