Dahua ASR1101M - RS485/Wiegand Card & PIN Code Reader

Dahua ASR1101M — RS485/Wiegand Card & PIN Code Reader

The Dahua ASR1101M is a surface-mounted card and PIN code reader that connects to a separate access control panel over RS485 or Wiegand34 (Wiegand26 optional). It reads 13.56MHz Mifare and 125KHz EM-ID cards and pairs a backlit, all-metal keypad with red and green status LEDs.

Who is it for?

The ASR1101M is designed for sites that already have, or are installing, a Dahua access controller — it is the reader that sits at the door and passes card and PIN data back to that controller, which makes the actual lock decision. It suits installers building or expanding a multi-door RS485/Wiegand access control system rather than anyone looking for a standalone unit.

Key specification

What you will need

• A compatible Dahua access controller to connect the reader to over RS485 or Wiegand — the ASR1101M does not make access decisions on its own
• RS485 or Wiegand cabling between the reader and the controller
• A door lock, power supply and exit device wired to the controller (not included with this reader)

Frequently asked questions

Does the ASR1101M work as a standalone unit?

No. It is a reader only — it needs to be wired to a separate access controller such as a Dahua ASC panel, which handles the actual door decision.

Which cards does it support?

It reads 13.56MHz Mifare cards and 125KHz EM-ID cards, and also accepts PIN code entry via the backlit keypad.

What connection does it use to the controller?

RS485 or Wiegand34 by default, with Wiegand26 available as an option.

Is it suitable for outdoor use?

The supplied data does not confirm an outdoor/weatherproof rating for this model, so check with us before specifying it for an exposed installation.
