Safety Measures For Roller Doors: Light Barrier And Contact Strip

Editor   October 23, 2017   Comments Off on Safety Measures For Roller Doors: Light Barrier And Contact Strip

Appropriate safety devices are provided by the Technical Inspection Association (TÜV), which applies to commercial gateways and gates which 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 the own garage is particularly close to the heart, should take certain safety precautions. If you have a roller shutter and, especially when children or small animals are in the household, appropriate precautions should be taken to avoid possible injuries. The best safety devices for roller doors are light barriers and contact strips.

How does a light barrier work?

The so-called one-way light barrier consists of a transmitter and a receiver. The light beam source emits an infrared light beam, which only goes in one direction 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 without coming into contact with them. As a result, not only small children or animals, which are located in the area of ​​the garage door, are protected against accidents. Light barriers also protect vehicles against damage. When it comes to mounting, the light barriers are suitable for both external and internal mounting. Transmitter and receiver are connected to the control unit with a cable. You should be min. every 3 months.

How does a contact bar work?

Safety contact strips are used on roller doors to protect persons and objects against jamming. They are used as a srew-joint protection against crimping and cutting. The contact strip is mounted as an additional safety device. It detects the obstacles in the roller door area and stops and reverses door movement when it encounters an obstacle by passing a contact to the control. The Rolladenplanet is available with either a wired or a wireless safety contact strip.

It should be noted that the light barrier does not react to all obstacles. An example of this can be a conductor, which is located in the area of ​​the garage opening and does not interrupt the light beam. In this case, the conductor is not detected and can cause great damage. In the case of a contact strip, direct contact with an obstacle is required for this system to function. It is possible that a small child or animal can enter the garage without notice and be locked there without our knowledge. If you attach great importance to safety, it is recommended to have both safety devices. The light barrier kit is available from Rolladenplanet at a price of 69 €. The contact strips start from 109 €, whereby also the photoelectric switches with contact strips in the set are available. All safety devices are in our rolling gate configurator available ,
