Accessible communication systems must simultaneously address two of the three senses – sight, hearing and touch. The so-called two-sense principle ensures that entrance areas are accessible and usable for people with sensory impairments without the help of third parties. To meet these requirements, Bird Home Automation developed the special "D2100E Accessibility” intercom module. The new module is integrated into DoorBird intercom systems and is used in particular in public buildings such as educational institutions, hospitals and retirement homes.

On the “Accessibility” module, the current status of a DoorBird door station is visualized with three pictograms: Call, talk and open door. In addition, the module has a hearing loop that can wirelessly transmit the audio signal from the intercom to the visitor’s hearing aid. The visual display and induction loop make communication easier for people with hearing impairment and all hearing aid users. In addition, Braille can be added to the IP-based door intercoms so that the information is easy to feel. This also reduces the sensory barrier for people with visual impairments.

Existing IP video door stations of the D21x series can be retrofitted with the "DoorBird D2100E Accessibility” integration module. New door stations can be equipped with the additional module with just one click and ordered via the 3D configurator.
