This product operates on low-voltage DC 12V–24V and must be used with a compatible switching power supply. Direct connection to 220V AC is strictly prohibited, as it may damage the controller. The input terminals are polarity-sensitive (positive/negative). Reversing the connections is prohibited. All wiring must be performed with the power disconnected. Before powering on, verify correct wiring and proper light strip connection. Incorrect DC wiring or light strip installation may cause a short circuit and controller malfunction. This product is intended for indoor use only in dry environments. Exposure to strong wind, high temperatures, or severe vibration may impair sensor performance. The sensor detection angle is 120°, with an effective range of 1–3 meters. Maximum sensitivity is achieved when the sensor faces a person directly. AB sensor heads should be positioned according to site requirements. Operating instructions: - If both AB sensors are triggered within 6 seconds, the light strip illuminates inward from both ends. - If AB sensors are triggered continuously for more than 6 seconds, the light strip illuminates preferentially in the direction of the first-triggered sensor. - Adjustable light-on duration: 3, 5, 10, 15, or 30 seconds. - If motion is detected again during the delay period, the timer resets and the light remains on for the full set duration. - Short-circuit protection: The status indicator LED flashes if a short circuit occurs.
