To improve is to change; to be perfect is to change often. Based on customer feedback and continuous research by our technical engineers, TOPENS KD702 and AT602 control panels have been upgraded. This upgrade allows the KD702 and AT602 to be connected to the ET24 Electric Gate Lock and the TEW3 Vehicle Sensor Exit Wand, which improves the user experience. For AT602, we also add a near-end limit switch to better protect the motor. Let's keep exploring and improving to be a better version of ourselves.
