Rechargeable motor cylinder

ÜTopic is probably the smallest motorized cylinder lock in the world with integrated Bluetooth!

ÜTopic is a retrofit motor for mechanical locking cylinders, which can be controlled via a free APP. It enables the motorized opening and closing of the door. The automatic control takes place either by means of fingerprint reader, radio handheld transmitter or with your own smartphone (Bluetooth).

The APP (Android & IOS) must be installed on the respective smartphone during commissioning. Additional authorizations can be generated and managed, which can be sent to other users by means of a code. Time-defined authorizations can also be easily set via the APP: This allows, for example, automatic locking at certain times, access authorization for a limited period.

ÜTopic, with its simple operation, sleek design and rechargeable battery, provides greater security and convenience in the home. There is no need to change batteries, it only needs to be recharged every 60-90 days with a charging cable (Micro USB interface).

ÜTopic can be used for all doors with cylinder lock and is perfect for retrofitting. It does not require any wiring of the door leaf. The existing cylinder does not need to be replaced, but can continue to be used. The key must be sawed off according to the template. It is important that the profile cylinder protrudes 2 mm. Alternatively, the profile cylinder can be replaced by a cylinder already prefabricated by Südmetall, including 4 keys. This also eliminates the need to cut the key.
