What safety sensors does a garage door need in Dubai?

A garage door opener should have photocell sensors near the floor that stop and reverse the door if something crosses the beam, plus force-sensing on the motor. The sensors sit on both sides of the opening and must be aligned, clean and at the height recommended by the manufacturer. In Dubai, sun glare, dust and cleaning water can disturb alignment, so check the indicator lights. If the door reverses for no reason or will not close, misaligned sensors are a frequent cause. Never bypass the sensors to make the door close. A technician can test them properly and the photocell safety sensors page explains the options.
