1. Introduction
1.1 Overview
Rosslare Enterprises Ltd.’s MD-W11 Wireless Access Control Door
Interface, is a quick, inexpensive solution for connecting remote
door devices, such as readers, locks, and REX Buttons to an
access control unit.
The MD-W11 Wireless Access Control Door Interface consists of
two units per door, one located near the controller (the Near unit)
and the other near the door (the Far unit). The Near unit is
connected to a Rosslare door controller (e.g., AC-215, AC-225, or
AC-525). The Far unit is connected to proximity card readers or
keypads (e.g., AY-K12 and AY-Q64B).
When a card is read or a code is keyed onto the keypad, the Far
unit transmits the information to the Near unit. The Near unit,
attached to the AC-225 or to another 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
