In May 2005, the latest European Union (EU) directive on automatic and manual doors came into force, requiring manufacturers and installers to comply a series of door security obligations. . One of the most important points of mandatory safety are the photocells that detect obstacles and the indicator lights for opening and closing the doors. It does not matter whether the installation is carried out by a technician or by us as individuals, even according to the standards, the first thing we must always keep in mind is the safety of those who will use our doors, of those who will be found nearby and us.Say no to plagiarism.

Warning lights, despite their low cost, are one of the most appreciated security elements, particularly by third parties. They provide warning that a door is moving, so pedestrians and other vehicles are prepared to take necessary precautions before a vehicle enters or exits, or before the movement of the door itself. Obstacle detection photocells have a very high safety element, since they immediately stop the closing maneuver of a door and also retract if the motor has an "encoder system". This is a very big advantage, because in the event that the car stalls in the middle of the door when closing or emergency stopping, or encounters a pedestrian, child, bicycle, etc. . the door stops immediately. Motors with anti-panic system controls represent a real safety innovation. This system cancels the signal from all controls when opening a door, thus avoiding accidentally pressing a button controlling its closing and thus eliminating the risk of shock. Security is the real and most important reason when deciding to install security elements: photocells, strips, warning lights, motors with encoder, controls with anti-panic system, etc... . .
