1. This product uses low-voltage DC 12V-24V to work, and must be connected to a switching power supply. It is prohibited to directly connect to 220V, otherwise the controller may be . 2. The input port has polarity (positive and negative), and reverse connection is prohibited. The wiring operation should be performed in a power-off state. After the wiring is completed, the installation and lighting connection should be checked for correctness before powering on. If the DC voltage wiring or lighting installation is incorrect, a short circuit may occur, causing the controller to malfunction. 3. This product is only suitable for use in a dry indoor environment. Strong wind, high temperature or severe vibration may cause sensor failure. 4. The sensing angle is 120 degrees, the sensing distance is 1-3 meters, and the sensor is most sensitive when facing people 5. AB sensing heads should be arranged according to the site settings. Additional operating instructions:1. If the AB sensors are triggered simultaneously within 6 seconds, the light strip will run inward from both ends. If the AB sensors are triggered continuously for more than 6 seconds, the light strip will preferentially run in the direction of the first triggered sensor 2. Set the light chasing time: 3. Single, double, three, four, five 4. If the induction continues during the delay period, the light strip remains on = the total time from A to B + delay time. 5. Short circuit protection device: In the short circuit state, the status indicator light will flash.
