Barrier-free access
Newly introduced standards and demographic trends are making barrier-free construction standard practice in many areas. At the same time, there is an increasing need for greater convenience and security. Siedle combines the two – with products that can be operated easily by nearly everyone, and with specialised technology for particular requirements.
Barrier-free access from Siedle in practice
What is special about the hearing aid compatible receiver?
Outstanding voice quality even with a hearing aid: the compatible receiver can be connected to hearing aids via an induction loop. The wearer can hear the visitor directly through their hearing aid.
The technology can be retrofitted to all current in-house telephones. The original receiver is simply replaced with the compatible model.
The hearing aid compatible receiver conforms to the ETS 300 381 European standard. It is available as an accessory in white.
Overcome physical and functional hurdles
Indispensable for barrier-free access: the status display . This also provides the hearing-impaired with clear feedback from the intercom.
Barrier-free construction is about far more than installing wheelchair ramps and widening doors. Buildings must also be capable of overcoming functional hurdles, for example for the hard of hearing. These requirements are formulated in Germany, for instance, by the DIN 18040 standard: “In the case of duplex intercom systems, an optical signal must indicate that the other party is ready to hear. In manually activated doors with electrical door latch release (known colloquially as a buzzer) release of the door must be signalled optically or by means of a tangible vibration."
The status display meets these requirements:
Siedle systems are not developed specially for buildings with barrier-free access. But they are based on principles which make them ideal for barrier-free applications. One of these is the huge flexibility of the systems – they make nearly everything possible, inside and out. For nearly every structural environment. And for nearly every functional requirement.
Thanks to their modularity and adaptability to customer requests, the Siedle systems open up almost infinite possibilities. Whether surface-mounted or flush-mounted, with access control, letterbox or camera, lots of things are possible.
Huge flexibility inside, too: wall-mounted or table-top devices, with buttons or a touchscreen, mobile devices and the Siedle App as well as interfaces with the telephone system and PC – flexibly positionable depending on what is desired and needed.
Maximum flexibility when integrating the functions: Depending on requirements, the functions can be differently positioned. They permit different mounting heights, for children and wheelchair users or for lorry drivers who use the intercom from the driver’s cab.
The flexible positioning of the letterbox outside permits a number of customised layouts without anyone being inconvenienced by the letterbox. It may be important, for example, for wheelchair users to be able to position themselves underneath letterbox systems.
For barrier-free design and intuitive operation: Universal Design
Barrier-free design also means: Everyone should be able to operate technology intuitively. American architect Ronald L. Mace, who himself contracted polio, coined the term Universal Design for this. He came up with five principles for a generally accessible environment. Siedle fulfils all of them.
The first rule is: Avoid unnecessary complexity. Siedle Axiom only has a few mechanical buttons. Clear icons indicate the key functions. Siedle Axiom is intuitive to use – like all Siedle products.
Second principle: Take consistent account of the user's expectations and their intuition. Clear contrasts guide the hand to the correct operating elements. These are learnt and consequently can be operated intuitively: the receiver takes the call, the key opens the door.
Third principle: Support a wide range of reading and language abilities. For the visually impaired, Siedle offers an extra-large call button with Braille. For the hearing impaired, the status display signals the active status. Inductive coupling amplifies the signal for hearing aids.
Fourth principle: Mark information according to its importance. The buttons for the most important functions, speaking and door release, are highlighted by their size and/or colour. This prevents the wrong button being pressed by accident.
The backlit symbols of the status display show the hearing impaired that the bell inside has rung, that a call connection has been set up or the door release has been activated.
Siedle door communication is incredibly versatile.
