Aiphone AC-2DM-B Two-Door Controller with Integrated PIR/REX – Black Enclosure, Wired Connectivity, Supports Back-to-Back Readers
Two doors. One controller.
The AC-2DM-B is a two-door access controller with a built-in PIR motion sensor and request-to-exit. It mounts above an interior doorway and supports back-to-back Wiegand readers.

Every door needs a reader, a REX and a lock supply.
Separate boxes for each add wiring, mounting points and more parts to manage. A controller that folds them together keeps the doorway installation simpler.
Built for the doorway
Reader inputs, relays, motion sensing and diagnostics sit in a single wired unit.
Back-to-back Wiegand readers
Two Wiegand reader inputs support credentialing from both sides of an entry point.

card holders
The controller supports up to 100,000 card holders.
Integrated PIR and REX
The infrared motion sensor provides request-to-exit without a separate sensor.
Relays, inputs and lock power
Two solid state dry contact relays, four configurable inputs and integrated lock power (12VDC, 500mA).
Built-in diagnostic LCD
An onboard display helps with diagnostics, and custom scripting and actions are available.
