Control Units (BUD)

The Intercom Control Unit (BUD) is the "brain" and heart of any multi-apartment security system. It is responsible for providing stable power to the door station and electric lock, storing the subscriber database and authorized electronic keys in its non-volatile memory, and managing the door release algorithms. The Techno Trade catalog features field-tested control units that are ideal for building new networks or upgrading existing coordinate systems.

Our solutions (including equipment completely compatible with the VIZIT series) ensure fail-safe system operation, robust data protection, and support for modern access standards (including operation with clone-proof MIFARE keys). We offer control units with an intuitive configuration architecture, which significantly simplifies programming and maintenance for installation companies.
