Appropriate safety devices are provided by the Technical Inspection Association (TÜV), which apply to commercial gate systems and gates that can be operated without a view of the gate (for example via radio control) and are located in the public area. If the safety in your own garage is particularly important, should take certain security measures. If you have a roll-up door and especially if you have children or small animals in the household, you should take appropriate precautions to avoid possible injuries. The best safety devices for roller shutters are light barriers and contact strips.
How does a light barrier work?
The so-called one-way photocell consists of a transmitter and a receiver. The light beam source emits an infrared light beam that goes in one direction only and is then picked up by a sensor. As soon as the light beam is interrupted by an obstacle, the automatic garage door movement is stopped and reversed. This system detects moving objects in this way without coming into contact with them. This not only protects small children or animals in the garage door from accidents. Photocells also protect vehicles from damage. When it comes to mounting, the photoelectric sensors are suitable for both outdoor and indoor installation. Transmitter and receiver are connected to the controller with a cable. You should min. dry cleaned every 3 months.
How does a contact strip work?
Safety contact strips are used on roller shutters to protect persons and objects against pinching. They serve as closing edge safety at crushing and shearing points. The contact strip is mounted as an additional safety device. It recognizes the obstacles in the roller door area and stops and reverses the door movement when it encounters an obstacle by passing on a contact to the control. At Rolladenplanet, either a wired or a wireless safety contact strip is available.
It should be noted that the light barrier does not react to all obstacles. An example of this may be a ladder that is located in the area of the garage opening and does not interrupt the light beam. In this case, the ladder is not detected and can cause great damage. A contact strip requires direct contact with an obstacle for this system to work. It can happen that a small child or animal runs unnoticed into the garage and is locked there without our knowledge. If you attach great importance to safety, it is recommended to have both safety devices. The light barrier set can be purchased from Rolladenplanet at a price of 69 €. The contact strips start from 109 €, whereby the photoelectric switches with contact strips are also available in the set. All safety devices are in our rolling gate Configurator available ,
