i.About The Product The device is designed based on the Toyota LS400 central control door lock and alarm system to holistically demonstrate the structure and operation of the system. The device applies to theoretical teaching and maintenance training of the central control door lock and alarm system in secondary and senior vocational skill schools, normal education and training institutions. ii.Features 1.A real and operable central control door lock and alarm system is used to illustrate the structure of the system. 2.Four doors of the vehicle are closed or opened simultaneously by operating the key or lock switch. If the alarm system is enabled after the ignition key is closed and the alarm status is set, the alarm siren sounds, the flasher blinks, and the starter breaks. In this way, the device demonstrates operation of the central control door lock and alarm system. 3.The training panel is made of advanced aluminum-plastic plate with characteristics of not less than 4mm thick, corrosion resistance, impact resistance, pollution resistance, fireproof, and moistureproof. Its surface are processed by special craft and spraying primer. Never fade color circuit diagram and working principal diagram are painted on the board whose surface coating with varnish. The trainees can learn and analyze the working principle of the control system by referencing the diagram and the real object. 4.The training panel is installed with detection terminals to detect electric signals, for example, resistance, voltage, current, and frequency, of circuit components of the central control door lock and alarm system. 5.The training panel's base frame is made of steel and the surface is paint-coated. Self-retention wheels are installed and a 24 0cm tabletop is fixed on the base frame to place materials and light testing devices. 6.Instead of using accumulators and requiring charging, the training panel connects to a 220V AC voltage which changes to a 12V DC voltage through the internal circuit. The 12V DC voltage protects the training panel against short circuit. 7.Equipped with intelligent fault setting and appraisal system, include fault setting, troubleshooting and assessment functions etc. iii.
