1. Introduction
1.1 Overview
The Rosslare Enterprises Ltd. 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 (in 26 Wiegand format only) 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.
1.2 Features
The MD-W11 Wireless Access Control Door Interface includes:
•Bi-directional RF data communication
•Wiegand 26-bit reader communication
•Lock and door relay commands
•Tamper, door monitor, and REX messages between the
controller and the interface unit
•Rolling Code to increase security
•Four different RF channels to prevent collisions

3. General Features
The general features of the MD-W11include:
•Maximum range of 200 meters (650 ft) outdoors,
depending on RF-related environmental conditions.
•Overall response time of 500 ms when used with
Rosslare’s AC-225 controller and readers. Response time
depends on RF link quality and the controller/reader’s
response time.
•Built-in charger for up to 12VDC, 7Ah backup battery on
the Far unit.
•Compatible with 26-bit Wiegand reader format keypads
and all of Rosslare’s readers.
•Case and wall tamper protection. Tamper events from
either near or far sides are reported from a tamper
output on the Near unit.
•Transfers proximity card information and LED control,
reader tamper, lock relay commands, REX and door
monitor events between the coupled units.
•Optional MD-W11BP battery pack housing with space for
12VDC/800mAh, sealed lead-acid battery. Suitable for
indoor use.
•Available in 868 MHz band.
•Outputs to report event signals.
•The Near unit is powered from the controller's power
supply. The Far unit is powered by a local wall
transformer. A built-in charger provides battery backup.

4. Installation and Wiring
The Near and Far units of the MD-W11 are installed and wired as
follows:
4.1 The Installation Kit
The installation kit of the MD-W11 interface includes:
•MD-W11N Near Unit: The Near unit sends the Controller
the Proximity card ID or Keypad code as though it were
a local reader. Following controller code/ID verification,
the lock relay receives a command (transmitted to the
Far unit) to open the door.
•MD-W11F Far Unit: The Far unit is connected to a
proximity card reader and/or keypad, and controls the
door lock relay.
•MD-W11BP Battery Pack: The Battery Pack is mounted
only on the MD-W11 Far Unit side (See Installing the MD-
W11BP Battery Pack, on page 18).
The MD-W11N and the MD-W11F are connected to the controller
and the door components (lock, door monitor, reader). Both units
are transceivers: the Near unit receives the data transmitted from
the Reader, and sends it to the controller. If authorized, the
controller sends authorization to the near unit, which transmits
authorization to the Far unit. The Far unit then opens the door.
The Wireless Access Control Door Interface makes the transfer of
data between the Controller input, the outputs, and the door
components (Lock, Reader, Door Monitor, Exit Button) transparent,
as if the door components were connected directly to the
controller.
