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.

Many years of use in inhospitable conditions have taken their toll on some systems in the Vario 511 series. An adapter enables easy replacement with its successor; while the flush-mount housing remains in the wall. The matching retrofit panel covers any visible differences on the wall.
