||App upgrade. For systems made from 1952.|
Through the new IQ in-house telephone, even older intercom systems can get access to mobile door communication. Millions of these systems are already installed – and now they can all be upgraded to use the app. This connection to cyberspace works no matter how old the system: the Siedle App securely delivers door calls to residents’ mobile end devices
The new IQ in-house telephone is available for 1+n and 6+n installation systems.
However, in many cases only individual devices are defective or have become unsightly, particularly indoors. For this type of case, Siedle offers a special variant of the current design line, the exchange telephone HTA 811. In terms of its design and function, it corresponds to the standard in-house telephone, but can be integrated seamlessly into an existing 6+n system.
Benefit: In the event of a defect, it is not necessary to exchange the entire system, only the affected call station. A difference that can save thousands of Euros - our contribution to investment security.
