Secure Relay I/O Module
Installation Manual

1. Introduction
The MD-25TB is a Secure Relay I/O Module for use with Rosslare's
Secure Stand-Alone Controller Unit. The secure module provides
power to the Controller Unit. The Controller Unit communicates with
the secure module through a Rosslare proprietary protocol, providing
instructions to activate the lock/auxiliary relays and a built-in speaker
(with bell and siren tones). The secure module also communicates
the REX input status to the Controller Unit. A red LED indicates the
secure module power status. The secure module includes
removable terminal blocks for ease of wiring and installation.
The MD-25TB isolates the lock from the Controller Unit, securing
lock functionality even if the Controller Unit is tampered with. If the
data line between the Controller Unit and the secure module is cut,
the system detects the data line has been tampered with and
generates a one-minute siren and closes the lock output. In addition,
the auxiliary relay can be activated by the Controller Unit.
The MD-25TB is designed to be used together with Rosslare's
ME-0515 Multipurpose Power Management Enclosure, providing
optimum performance and convenience together with universal AC
input and a UPS using a Sealed Lead Acid backup battery.
