When the garage door is descending and the light is blocked by obstacles (such as pedestrians, pets, vehicles, cardboard boxes, etc.), the sensor will immediately send a signal to the garage door opener, triggering the "emergency stop + reverse ascent" action to prevent people from being pinched or items from being damaged.
Our GSTB-R STB-BL Garage Door Sensor is made of high quality ABS material, which has been tested many times for quality and reliability. The garage door sensor emits an invisible of light that automatically flips the garage door when it encounters an obstacle, preventing accidents.
Installation and inspection steps for garage doors: First, the power supply needs to be cut off. Determine the installation position of the sensor and ensure that the sensor height is uniform. The probe must be directly aligned.
2. When connecting the sensor wires to the corresponding interface of the garage door controller, distinguish the positive and negative poles and do not connect them in reverse. When the sensor indicator light is on, it indicates that everything is normal.
