Rosslare MD-IO84 Installation Manual

Installation Instructions

1. Introduction
The MD-IO84 is an optional I/O expansion board for use with
Rosslare Security's family of state-of-the-art networked access
controllers. The expansion board adds an additional four relay
outputs and eight supervised inputs to the access control
panel.
The host access controller has complete control over the
additional inputs and outputs of the MD-IO84 expansion
board. The inputs and outputs can be configured using an
access control software system such as Rosslare Security's
VeriTrax AS-225. The software system also configures the MD-
IO84's input connection topology.
This guide explains how to install and begin working with your
new MD-IO84 access controller expansion board.

3. Installation
3.1 Attaching the MD-IO84
1) Disconnect power to the access control panel before
attaching the MD-IO84.
2) To remove the MD-IO84 cover, lightly pull one of the cover
knobs away from the circuit board. The entire cover
comes away from the board.
3) Remove the label on the cover of the access control
panel marked "Remove to install I/O board".
4) Insert the MD-IO84 with its 10 pin male connector fitting
into the access control panel 10 pin female connector.
The text on the MD-IO84 must face the same way as the
text on the panel's cover.
5) Tighten the four Philips screws on the MD-IO84 circuit
board.
6) Ease the corners of the cover back over the board. The
text on the cover must face the same way as the text on
the circuit board.
