||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 buzzer) release of the door must be signalled optically or by means of a tangible vibration."|
The status display fulfils currently relevant statutory requirements for the disabled and equality legislation as well as "barrier-free construction" standards in respect of visual signalling at the door.
The status display provides an optical indication of which function is currently active. It can be supplemented by an additional acoustic signal. This affords people with restricted vision clear feedback from the intercom.
The status display is available for the installation systems In-Home bus, Multi and Access. It can be integrated in the design lines Siedle Vario, Classic and Steel.
