Two-Door Access Control Starter Kit

The ACS-2DR starter kit is a 2-8 door master door controller which includes a master door control board and a two‑door expander board (AC‑2DE). This kit fits into the AC-CA1 enclosure (sold separately), which includes a power supply.

Each AC-2DE has contacts and reader inputs to control two doors. Up to three AC-2DE door control boards can be added to the AC-CA1 enclosure, allowing it to control up to eight doors. For each door, the AC‑2DE provides two dry contact outputs, one wet contact output, and three programmable contact inputs.

This kit can be used on its own or as part of a larger AC Series access control system with additional AC-2DM modules and ACS-2DR panels. The system is managed using the AC Nio management software, with partitioning options available.
