Installation and Wiring
The Near and Far Units of the MD-W11 are installed and wired as
explained in this chapter.
3.1
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 Section
3.7).
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 transfers the 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.
