Overview
The MD-W11 Wireless Access Control Door Interface is a quick and
inexpensive solution for connecting remote door devices, such as
readers, locks, and Request-for-Exit (REX) buttons to an access control
unit.
The MD-W11 consists of two units per door – one located near the
controller (the Near Unit) and the other near the door (the Far Unit)
(Figure 1).

The Near Unit is connected to a Rosslare door controller (such as AC-
215, AC-225, or AC-525). The Far Unit is connected to proximity card
readers or keypads (such as AY-K12 and AY-Q64B).
When a card is read or a code is entered by keypad, the Far Unit
transmits the information to the Near Unit. The Near Unit, attached to
the controller, determines whether or not to open the door. The
controller then sends the message to the Near Unit, which transmits it
to the Far Unit, and if authorized, the door is opened.
Changes or modifications to this equipment not expressly
approved by the party responsible for compliance (Rosslare)
could void the user’s authority to operate the equipment.
