Security on both sides of the door is a top priority and is one of the key features of Südmetall’s ÜLock radio security locks.

With the ÜLock Cable, wiring of the door leaf is necessary.

Südmetall combines the extremely high-quality ÜLock Cable radio security lock with a practical 2-core cable, which on the one hand provides the power supply for the lock and on the other hand transmits the opening signal from the control system directly to the lock. The data transmission is protected against manipulation at all times. All relevant status messages can be called up at any time.

The electronics are completely installed in the lock case, so there is neither an attack surface nor any possibility of manipulation from the outside. Thanks to the panic function on the ÜLock-B, the door can be opened from the inside at any time and the self-locking function protects the door from the outside. The ÜLock-Z is suitable for particularly sensitive rooms (WITHOUT panic function!).

In addition to ease of use, design freedom is offered in terms of hardware selection, so that the requirements of the respective object are met.
