Dahua DHI-ASR2101A-D - Waterproof IP66 Card & Keypad Reader

Dahua DHI-ASR2101A-D — Waterproof IP66 Card & Keypad Reader

The Dahua DHI-ASR2101A-D is a waterproof card and password reader built with PC material construction and an acrylic panel, designed to sit at a door as the read point for a separate access control panel.

Who is it for?

This is a reader, not a standalone controller — it needs to be wired back to a compatible access control panel (such as a Dahua ASC-series controller) over RS-485 or Wiegand (W26/W34) to make access decisions. It suits installers adding or replacing an outdoor-rated 125KHz card and PIN entry point on a door, gate or barrier that is already served by a controller.

Key specification

What you will need

• A compatible access control panel/controller to connect this reader to — it does not make access decisions on its own
• A suitable power supply for the controller side of the installation (the reader itself is powered from the controller/reader bus)
• Door hardware (electric lock, strike or maglock) wired to the controller, not to the reader
• Cabling suitable for RS-485 or Wiegand runs between the reader and the controller
