Two-sense communication for elevators with flexyPage Messenger


In the event of a malfunction with trapped persons, elevators must be equipped with an emergency telephone to a permanently manned emergency center in accordance with DIN EN 81-28. However, if the trapped persons have a hearing impairment, they cannot communicate properly with the emergency center via the acoustic emergency telephone. With our flexyPage Messenger we offer a solution to equip all kind of elevators with a visual second communication channel for trapped persons with a hearing impairment according ASME A17.1-2019, which exceeds the requirements of DIN EN 81-70. The function is supported by all flexyPage displays, from 18 cm (7") to 96 cm (38") and can be used together with all commercially available emergency telephones. The operation in the elevator can be done via touch screen or the elevator buttons. With our flexyPage displays, you can easily implement two-senses communication (2SC) for persons with a hearing impairment in any elevator, both in new construction and in existing elevators. 

Two-sense communication for elevators with flexyPage displays

Two-sense communication with flexyPage Messenger

According ASME A17.1-2019 the flexyPage Messenger solution provides a visual text based communication between authorized personel (e.g. in an emergency call center) and the elevator car. After activating an emergency call the authorized personel can establish the two-senses communication and the camera to look into the elevator car. The display in the COP shows a message that the communication is established and the text messages and questions from the authorized personel. The trapped persons can anser the question using the touch screen or the buttons of the COP. The flexyPage Messenger allows communication in different languages and the sending of free text. The displays communicate directly with the acoustic emergency call devices.
Signalling of the connection establishment

Signalling of the connection establishment  

When an emergency call is triggered, the acoustic emergency call devices establish a connection to the control centre and identify themselves there. This may take a while and only then can the call centre be communicated acoustically. The status, whether the connection is currently being established or can already be spoken, is usually only displayed with two small LEDs or pictograms. 

The flexyPage displays can show the status when the connection is established in an understandable way with animated graphics and text.

Unlimited languages

Elevator users speak many different languages and flexyPage Messenger also supports unlimited languages. These can be defined by the emergency call centre for each elevator. When establishing a connection, the user can select his language in the elevator and communicate with the emergency call centre in that language. In addition to predefined text blocks with questions and answers, Messenger also offers the option of automatic translation. 

Text blocks and free chatting

Text blocks and free chatting 

The flexyPage Messenger allows you to send free text to the person included, just like a text messenger app. In addition, the Messenger allows you to send possible responses, which the user can easily select or confirm. Text blocks including the possible replies can also be pre-defined in the Messenger software. 

Video connection into the elevator

Optionally, the displays can be equipped with a camera that can only be activated from the control centre in the event of an emergency. This enables the control centre to get an exact picture of the trapped persons and to quickly initiate the right emergency measures. 

Functionality of the flexyPage Messenger

When the emergency button is pressed, a voice connection to the emergency call center is established via the conventional emergency call system. If no verbal communication can take place between the trapped persons and the emergency call center, the call center switches to the text chat of the flexyPage Messenger. If there is still no response via text chat, the emergency call center can activate an optional camera through the flexyPage Messenger.

Logging and data backup

Logging and data backup

In connection with the emergency call, it is important that the processing of emergency calls is completely logged in the control centres. The flexyPage Messenger logs all events with status, question, answer and time stamp for later traceability. The logs can be exported and professionally backed up.

Emergency call center

If an elevator is to be equipped with a 2-senses emergency call, the emergency call center to which the elevator is connected must support this service. Currently you can connect your elevator with the hearing impaired function to the following emergency call centers:  

 BavadoABD Notrufzentrale ABD Notrufzentrale  

Emergency telephones

The displays with the 2-senses communication can be used together with all audio emergency call devices in your elevator. In our laboratories we have successfully tested the function with the devices of the following manufacturers:


Leitronic  Löffler  SafeLine  MS

flexyPage Messenger and Campaign

Visual communication is very helpful for trapped persons with a hearing impairment. If an elevator is equipped with a display for two-sense communication, it is useful to use the display for other functions as long as no emergency call is active. 

The flexyPage displays can show all elevator information as well as multimedia or internet data. The integrated Timer+Event system allows flexible switching between different applications and designs. This enables the flexyPage display to be used as a normal TFT elevator display in a new building and to switch to the Messenger application in the event of an emergency call. For easy retrofitting, the elevator can be easily extended with an additional display, which normally shows e.g. information about the building, a tenant directory, messages to the tenants or local advertising and can be used for visual communication in case of an emergency call. Here, the flexyPage Messenger and Campaign applications complement each other ideally.
