CATALOGUE

The Impro Multi-discipline
Readers are compact and robust
Passive Proximity Readers.
New technology allows the
Multi-discipline Readers to read
both 125 kHz and 13.56 MHz
frequency Tags.
These Readers fit seamlessly into
new or existing applications
allowing you to upgrade Tag
technology without replacing
existing Tags.
The design of the Multidiscipline Reader allows you to
use them with a variety of
Terminals and Controllers, within
third-party or Impro Access
Control Systems.
When used with the Wiegand
Reader Module, IXP220
Controller, IXP20 Controller or
the Impro iTRT, these Readers
use AES 128-bit Encryption with
a Diffie Hellman key exchange
thus ensuring secure
communications on the
Wiegand Bus.
You can use the Multi-discipline
Readers in both indoor and
protected outdoor
environments.

The Keypad Reader versions offer
12-button Keypads, allowing PINcode entry. All models include a
single tone, single volume Buzzer
and a single tri-coloured Red,
Green or Amber Status LED. You
can control the functions of the
Buzzer and Status LED to suit the
needs of your application.
The Junction Box versions are
suitable for indoor applications..

Each reader offers a Scanner Inhibit Input. When you connect the
Scanner Inhibit Input to GROUND, the Multi-discipline Reader’s scanner
turns off and inhibits the keypad (Keypad Model MDK901 & MJK900
models) while connected. When you release the connection, the Reader
returns to normal operation.
A conveniently placed link allows you to use the Reader in OEM
applications using either 26-bit or 44-bit Wiegand Protocol.

In OEM applications, connect the Purple and Grey wires to a
Dry Contact Input. In Access Portal Systems (connecting to a
Wiegand Module clustered with a Cluster Controller Module),
and on IXP20 (iTRT version) and IXP220 Systems (when
connected direct to the Controller or via the Impro iTRT) it is
unnecessary to connect these lines as the Software handles
the Anti-tamper.
