With Siedle: more than just modernization

Simply replace the in-house telephone – and connect to the Siedle app. For systems from 1952 onwards. Siedle IQ connects existing systems to the future.

Greater convenience plus added security – with very little mounting or installation work: Usually, the wiring from an old doorbell is suitable for vision and surveillance as well as speech and door release.

Renovate your intercom indoors – without any new cabling, great effort or high costs. Simply replace your old in-house telephone with a new one – with an award-winning design and an array of design options. And you can enhance the system with the Siedle app.

Only replace what you really need to: The retrofit version of the Siedle Classic door station fits exactly on the flush-mount housing of even the oldest Siedle series [TL 111]; which means there’s no need for any work on the masonry. If you have an older Siedle letterbox [such as the TL 411 - series], then only the fronts are replaced with the Siedle Classic retrofit systems’, the built-in housing can still be used.
