## Long description

The Dahua Technology Two-button Call Button Module VTO4202F-MB2 is a compact accessory designed for integration with Dahua access control and intercom systems. Finished in silver, the module measures 100 mm wide, 30.5 mm deep and 49.9 mm high and is supplied as a single unit. It provides two tactile call buttons that allow visitors or residents to place distinct calls within a multi-station door entry installation, supporting organized visitor routing and straightforward operation.
Advantages

Its two-button layout enables assignment of separate call targets (for example, apartment and concierge) and simplifies user interaction. The silver finish is durable and neutral, easing integration into a variety of architectural styles. Single-piece packaging makes it easy to store and replace existing modules in retrofit or new-install scenarios.
