Reliable Anti Trap Systems for power operated windows
Power operated windows and doors
Whether controlled natural ventilation, smoke and heat extraction or barrier-free access: modern building technology today is unimaginable without power operated facade components. Doors, windows and vents open and close by remote control. The automated control presents a constant danger of people getting trapped and injured.
Current guidelines and standards
Various guidelines and standards contain statements concerning the safety of power operated building elements according to the Directive 2006/42 EC on machinery. As far as windows are concerned, most of these guidelines are only partly applicable.
The KB.01 leaflet, version 2014-11, published by the Association Windows and Facades VFF facilitates the implementation of suitable protective measures. A risk evaluation for power operated windows and measures to be taken for safeguarding them are depicted therein.
Depending on the design, configuration, use and position of the windows, it is, according to the KB.01 leaflet issued by the VFF, necessary to check if requirements from further guidelines and standards also apply.
In addition, chapter 4.1.2. of the Technical Rule ASR A1.6 “Windows, overhead lights, light-transmissive walls” refers to special safety requirements for power operated windows and depicts exemplary safeguarding devices. Among other things it refers to the use of pressure sensitive safety devices, for example safety edges, for the prevention of mechanical hazards.
Mayser Anti Trap Systems
Mayser Mini Safety Edges have been used as Anti Trap Sensors for several years now and have Proven use in Building, Medical and Automative Technology. Outstanding advantages of tactile protection in comparison with other systems are the extremely short response time the sensors – which are monitored for function – have, as well as the constantly reliable switching function, which is independent of climatic influences, incidence of light and soiling.
The sensors are used in situations where little or no overtravel and minimum installation heights are possible. Whether louvre windows, parallel vent windows or tilt and turn windows, Mayser Mini Safety Edges can be fitted inconspicuously into various shear openings – depending on the window shape – making them safe. Reliably.
