- Introduction
- 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.
- Caution:
- Changes or modifications to this equipment not expressly approved by the party responsible for compliance (Rosslare Ltd.) could void the user’s authority to operate the equipment.
- The MD-W11 Wireless Access Control Door Interface includes:
- Bi-directional RF data communication
- Supports PIN codes and card formats, such as Wiegand 26 bit, 32 bit, and PIN code 6 bit (see list of formats on page 8).
- 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
- Built-in charger for up to 12VDC, 7Ah backup battery on the Far 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 869 MHz (H) and 433.92 MHz (G) bands
- 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.

- 3. Installation and Wiring
- The NEAR and FAR units of the MD-W11 are installed and wired as explained in this chapter.
- 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 16).
- 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 (such as Lock, Reader, Door Monitor, and Exit Button) transparent, as if the door components were connected directly to the controller.
- The installation kit includes:
- One drilling template (Label /Sticker)
- One Security spline key
- One Security hex screw
- Four mounting screws
- Four wall plugs
- Fixed External antenna (G Model)
- The NEAR unit can be connected to a standard Rosslare controller, such as the AC-225.
- Decide where to mount the unit, and install it as follows:
- 1. Use the spline key to remove the case security screw from the back of the unit, as shown in Figure 4.
- Figure 4: MD-W11 Back Cover
- 2. Use the drilling template to determine where to drill holes in the wall.
- 3. Use the hardware to mount the back plate on the wall.
- Notes:
- We highly recommend to use the bottom left mounting hole, as it used for the purpose of back tamper when a person attempts to dislodge the unit from the wall. See Figure 4: MD-W11 Back Cover marked with A.
- 4. Wire the unit as instructed in the chapter on Wiring the MD-W11N Unit, below, and Figure 5: MD-W11N NEAR Unit Wiring Diagram, on page 12.
- Wire the following terminals between the Controller's Input and Output to the MD-W11N Near Unit, as shown in Figure 5:
- 1. Power supply connection (+12V and GND)
- 2. System tamper (STAM)
- 3. Supervision failure (SPV) - Far unit has supervision failure
- 4. Low battery (LBAT) - Far unit has low battery
- 5. AC Fail (AC) - Far unit has power failure
- 6. Data 0 (D0)
- 7. Data 1 (D1)
- 8. Reader LED control (LED input)
- 9. Far Reader Tamper (TMP)
- 10. Connection for lock (Lock input)
- 11. Relay 1 REX (output)
- 12. Relay 2-Door monitor (output)
- Notes:
- 1. System tamper (STAM), Supervision failure (SPV), Low battery (LBAT), AC Fail (AC) are outputs which can be connected to any input of AC-225 and in AxTrax this input should be configured accordingly (using Panel Links).
- 2. If either the Far reader or the Near reader, or both have been tampered with, the STAM status changes, and retains this status until both readers have been closed.
- Figure 5: MD-W11N NEAR Unit Wiring Diagram
- Figure 6: Sample Wiring Detail
- Note:
- Figure 6 shows sample input connections to any inputs, and is relevant to: AC-215/225/525.
- The relevant input can be configured to result in the required outcome, using AxTrax and Panel Links.
- Note:
- 1. The connection between the REX Input and Relay 1 is always COM+ N.O. or COM + N.C. so that only two lines connect this pair.
- 2. The connection between the Door Monitor Input and Relay 2 is always COM+ N.O. or COM + N.C. so that only two lines connect this pair.
- The Far unit can be connected to a standard Rosslare reader, such as the AY-K12. The optional battery box can then be attached to the wall next to the Far unit.
- 1. Attach the battery box to the wall with two screws.
- 2. Insert the wires from the reader and from the battery to the hole in the side of the Far unit box.
- 3. Attach the side of the unit box to the wall with four screws.
- 4. Attach the wires to the PCB.
- 5. Cover both the battery and the Far unit boxes.
- 6. Tighten the screws on the bottom of both boxes so that they remain closed.
- Wire the following terminals between the Controller's Input and Output to the MD-W11 Far Unit, as shown in Figure 7: MD-W11N FAR Unit Wiring Diagram on page 15:
- 1. 12-24 VAC or 15-24VDC to the VIN+ and VIN-
- 2. Optional backup battery that connects to BAT+ and BAT-
- 3. 12V and GND power output for the Reader.
- 4. Data 0 Wiegand (D0) (input)
- 5. Data 1 Wiegand (D1) (input)
- 6. LED - Reader LED control (output)
- 7. TMP - Input for receiving reader tamper alert
- 8. Normally Open (NO)/Normally Closed (NC) and COM of 5A Form C relay to the door’s lock
- 9. REX - Optional input for Request for Exit
- 10. DM - Optional input for door monitor contact
- Figure 7: MD-W11N FAR Unit Wiring Diagram
- Only install the MD-W11BP battery pack in the MD-W11 Far Unit.
- Decide where to mount the unit, and install the battery pack as follows:
- 1. Use the spline key to remove the security screw from the bottom of the case, and open the unit.
- 2. Use the drilling template to locate where to drill holes in the wall.
- 3. Use the hardware provided to mount the back plate on the wall.
- 4. Wire the battery pack as shown in Figure 8.
- Figure 8: MD-W11BP Battery Pack
- Note:
- The battery pack comes with a battery installed. The size of the case is compatible with Rosslare’s BT-05 12VDC / 800mA SLA rechargeable battery.
- In the Far unit only, connect the Red (+) and Black (GND) to MDW11F Bat (+) and Bat (-).
- Figure 9 shows the six LED’s (which indicate the unit’s current status) on the display panel of each unit :
- 1. PWR – Power ON
- 2. Tx – Sending transmission
- 3. Rx – Receiving transmission
- 4. ENRL – Enrolling
- 5. TRBL – Trouble
- 6. SYS – System OK
- Figure 9: LED Display Panel
- To install the MD-W11 units most efficiently, place the Near and Far units facing each other, rather than placing them at a 90º angle to one another.
- Both transmission and reception are improved if the Near and Far units have the same polarity.
- In addition:
- 1. Do not place any of the MD-W11 units next to an air conditioner, heater, blower, or an engine that generates a magnetic field.
- 2. Do not place any unit next to an electronic device that transmits RF or next to an access control reader or device.
- 3. Assure that metal fixtures and furnishings (e.g., doors or closets) are not in line with the Near and Far units.
- 4. Assure that the Near and Far units are at the same approximate height, preferably above head level.
- 4. Enrollment
- Prevent loss of transmission data by enrolling each pair of Near and Far units.
- One unit cannot recognize the unique ID of another unit unless both units are enrolled so that they can work together.
- The dipswitches on both units are set as follows:
- Dipswitches 1-4:
- Not used
- Must be in the ON position.
- Dipswitch 5:
- OFF or ON
- Used to set the channel.
- Dipswitch 6:
- OFF or ON
- Used to set the channel.
- Dipswitch 7:
- Enrolling
- Normal mode – ONEnrolling mode – OFF
- Dipswitch 8:
- Not used
- Must be in the ON position.
- Note:
- Only handle the Dipswitches when the power is OFF.
- Set the unit channels with Dipswitches 5 and 6.

- 433.00 MHz
- Note:
- Dipswitches 5 and 6 must be synchronized in the Far and Near Units.
- Choose the same channel for both units.
- If the LED’s flash, the dipswitches have not been set properly. In that case, first re-set the dipswitches, and then power the unit off and on.
- During enrollment, the enrolling LED blinks first, followed by the TX LED, which blinks when it is transmitting. The enrolling process is finished when the enrolling LED shines steadily.
- After enrolling, return dipswitch 7 to ON (normal mode).
- Note:
- Only handle the Dipswitches when the power is OFF.
- The current unit mode is indicated by a steady or blinking LED. The three modes (Normal, Enrolling, and Trouble) of the NEAR and FAR units are described in detail below.
- The normal mode is “idle,” and the LED’s behave as follows:
- PWR - Power ON - steady
- Tx - Sending transmission - blinking when sending
- Rx - Receiving transmission - blinking when receiving
- SYS - System OK – blinking
- Note:
- If SYS LED is not blinking, it indicates a serious error.
- A blinking TRBL indicates that there is trouble. Refer to the Trouble Mode for a list of possible problems.
- The following steps indicate how to set the Enrolling mode (for retention of transmitted data).
- 1. Set Dipswitch 7 on both units (Near and Far) to OFF.
- 2. Power up both units.
- 3. PWR IS steady and ENRL IS blinking.
- 4. The Far unit sends its ID to the Near unit.
- 5. The Near unit receives an ID and sends it to the Far unit
- 6. The Far unit receives the Near unit’s ID and ENRL is steady.

- 5. Operational Information
- The units should be no more than 300 meters from one another in an open field.
- The Far unit has one dipswitch with eight buttons, the default for all of which is On. The end-user only uses button #7 to enroll the Near and Far units. When the user turns button #7 to Off, the Near unit recognizes the Far unit so the units work with each other.
- The Far unit can also be attached to a REX (request for exit) button, a door monitor to indicate whether a door is open or closed, and a tamper to check whether the cover was opened. These indications are transmitted from the Far unit to the Near unit, which then sends them to the controller.
- The proximity reader reads card information, and sends it from the Far unit to the Near unit and to the controller to determine which door to open. If applicable, the controller sends authorization to open the door to the Near unit, which transmits the authorization to the Far unit, and the door is opened.
