Comelit 1224A Simplebus Door Digital Switching Device

Optimize multi-door entry control with the Comelit 1224A Simplebus Door Digital Switching Device. Designed for installers and facilities managers, this switching device streamlines access control for audio or audio‑video door entry systems with two or more doors, improving security, surveillance and monitoring across residential or commercial sites. The unit uses two 8‑position DIP switches to define user code ranges on the riser, making configuration fast and reducing commissioning errors. Built for the Comelit Simplebus ecosystem, the 1224A works with a standard 12V AC power supply (art. 1200) and mounts in a compact white enclosure (approx. 3.3" x 1.4" x 2.4"), saving space in equipment cabinets or panel boxes. By centralizing switching logic, the device reduces wiring complexity and helps ensure reliable call routing and access decisions—critical for secure entry systems and surveillance integration. Ideal for multi-tenant buildings, offices and gated communities, the 1224A delivers professional-grade performance with minimal setup time. Upgrade your intercom infrastructure and simplify ongoing monitoring—add the Comelit 1224A to your next access control project.
