What is the working principle of central door locks?
1 Answers
Central door locks work by converting the positive and negative power supply of the motor to complete the locking and unlocking process. The central lock consists of two double-contact relays and control circuits. When an unlock signal is received, the unlock relay engages, allowing current to pass through the motor to form a circuit. Central door locks are the abbreviated term for the central control door lock system, which consists of an operation switch, control unit, and actuator. The central door lock system includes components such as door lock switches, door lock cylinder switches, door lock motors, indicator lights, engine hood alarm switches, anti-theft antennas, control module receivers, remote controls, ultrasonic sensors, and audible and visual alarm devices.
