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 damaged. 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. ⑥. If the AB sensors are triggered simultaneously within 6 seconds, the light strip run inward from both ends. If the AB sensors are triggered continuously for more than 6 seconds, the light strip preferentially run in the direction of the first triggered sensor. ⑦. Set the light time: ⑧. Single, double, three, four, five ⑨. If the induction continues during the delay period, the light strip remains on = the total time from A to B + delay time. ⑩. Short circuit protection device: In the short circuit state, the status indicator light flash. ⑪. Part name: Staircase LED controller ⑫. Product model: UL1032 ⑬. Input voltage: DC12v/24V ⑭. Sensor head: 2 (A/B) ⑮. Color: As Shown ⑯. Material: plastic ⑰. Package Contents: 1 x LED driver, 2 x sensors, 2 x output lines. Only the above package content, other products are not included. ⑱. Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
