Comelit 1405 Digital Exchange for Systems with Quadra Inputs

Optimize your intercom and access control infrastructure with the Comelit 1405 digital exchange module. Designed for Simplebus2 2-wire systems, this audio/video switching peripheral delivers reliable routing for up to two Quadra-series entrances, making it ideal for small multi-entrance commercial buildings, apartment lobbies, and security-conscious facilities. Because the unit draws power from the bus line, installers save time and reduce cabling complexity—no separate PSU required. The compact 2 DIN-module footprint (35 x 90 x 58 mm) mounts neatly in panels or enclosures, keeping deployments tidy while supporting robust surveillance and monitoring workflows. As a Comelit-branded component, the 1405 ensures native compatibility with Simplebus Top digital intercom kits and maintains audio/video integrity across calls and camera feeds. If you need a dependable, space-efficient way to expand intercom entrances and enhance on-site security, the Comelit 1405 is a practical plug-in solution. Specify this digital exchange for your next intercom upgrade or access control expansion to streamline installation and improve monitoring performance.
