Dahua DHI-ASR2201A-D - IC Card & Password Access Reader

Dahua DHI-ASR2201A-D — IC Card & Password Access Reader

The Dahua DHI-ASR2201A-D is a slim, weatherproof IC card and password access reader. It reads 125KHz ID cards, accepts PIN entry on its built-in touch keypad, and talks to an access control panel over RS-485 or Wiegand (W26/W34). It is a reader — not a standalone controller — so it needs to be wired to a separate access controller to actually operate a door.

Who is it for?

This reader suits anyone adding or replacing a card/PIN entry point on an existing Dahua access control system, such as an external door, gate or barrier where an IP66 rating is useful. Because it only reads credentials, it must be connected to a compatible access controller that handles the door logic and lock output; the reader itself does not store users or make access decisions.

Key specification

What you will need

• A compatible Dahua access controller to wire the reader into — this reader does not work standalone
• An electric lock or strike on the door, with its own power supply
• Cabling suitable for RS-485 or Wiegand runs between the reader and the controller

Frequently asked questions

Does the DHI-ASR2201A-D work on its own?

No. It is a card and password reader, so it needs to be wired to a separate Dahua access controller, which is what actually makes the access decision and releases the lock.

What type of card does it read?

It reads 125KHz ID cards, so check your existing card stock is 125KHz before ordering.

Can it be used outdoors?

Yes. It has an IP66 rating, so it is protected against dust and powerful water jets, making it suitable for external doors and gates.

Which protocol should I use to connect it?

It supports both RS-485 and Wiegand (W26/W34) output, so it can be wired into most Dahua access controllers using whichever interface your controller and cable run support.
