MICROgarde™ Based Access Control System - Overview
TDSi MICROgarde™ type door controllers offer a fully featured door controller with up to
25,000 card memory.
MICROgarde I™ is capable of controlling 1 door with IN and OUT readers.
MICROgarde II™ is capable of controlling 2 doors with IN and OUT readers using our
Reverse LRC protocol.
MICROgarde™ is an intelligent door controller in that all card holder and access rules are
stored allowing complete operation should communications to the host communications
server be lost. All door controller types feature as standard storage for up to 1,000
events should this situation occur.
MICROgarde™ utilises an 8-bit data, 16-bit address microcontroller, which handles
central processing and control. A further microcontroller is fitted which handles low-level
and background tasks.
The firmware is flash-upgradeable, providing a means to upgrade the embedded software
when available.
A real-time clock (with integral battery backup) is fitted allowing the access decisions to
be made and time-stamping of the access events to occur. The clock is updated by the
host communications server regularly.

Features
2.1
Antipassback
MICROgarde™ door controllers feature antipassback facility across the doors within each
controller, preventing sharing of cards. Two types of antipassback are offered:
Timed antipassback – where the same key may not be used to gain access more than
once within a specified period. That key may however be used to gain access via
another door within that specified period.
True antipassback – used where there is both an in and an out reader. The key, once
used to gain access cannot be used to gain access again until it is presented at the out
reader.
Zonal antipassback – in conjunction with EXgarde Pro™ V4 software, the same key
may not be used to gain access to an inner area within a perimeter zone until it has
been validated at the perimeter zone reader(s). This functionality can be spread across
a maximum of 100 readers communicating with a single communications host.
Software Global Antipassback – in conjunction with EXgarde Pro™ V4 software, this is
supported across a maximum of 100 readers communicating with a single
communications host.
Antipassback is ‘hard’ whereby an event is logged that antipassback has been infringed
and the user is prevented from passing through the door. This is opposed to what is
described as ‘soft’ antipassback whereby only the event is logged but the user is still
allowed to pass through the door.

A forgiveness setting allows all cards that are currently subject to antipassback rules to
have their antipassback status automatically cleared (either at midnight or midday).
It is not possible to achieve a global antipassback system whereby all doors within the
access control system are covered unless our EXgarde Pro™ V4 software is used to a
maximum of 100 readers.
2.2
Door Controller – Time Groups
The system allows up to 64 time groups to be configured. Time groups determine when
the access groups can gain access to controlled areas.
2.3
Door Controller – Mantrap
MICROgarde™ controllers offer a mantrap feature that requires one door to be closed
before another is opened. This functionality is across 2 doors within the same controller.
2.4
Door Controller – Communications
MICROgarde™ door controllers can be connected via an RS-485 network. It is
recommended that no more than 20 controllers are connected to one portal on the
communications server PC to ensure adequate system performance.
Alternatively, a direct connection can be made (PC to door controller) through an in-built
RS-232 port.
MICROgarde™ IP door controllers also feature 10/100 Base TCP/IP port for connection
to an Ethernet over a Local Area Network (LAN) or Wide Area Network (WAN).
Connection is made via a standard patch lead fitted with an RJ-45 plug. A built-in RS485 converter allows connection of further units via an RS-485 network.
Should it be required to connect the door controllers using RS-232, a separate RS-232 to
RS-485 converter is available providing the facility to do so.
Communications to the MICROgarde™ door controller is conducted at 38,400 baud.
LEDs are fitted to the door controller board providing visual indication of communications
activity.
2.5
Door Controller – Enclosure and Design
MICROgarde™ door controllers with an integral power supply are fitted within a steel
clamshell type painted enclosure with a single fixing (non-security type). The power
supply provides power for both controller and locks.
MICROgarde™ door controllers without an integral power supply are fitted within an ABS
plastic box fitted to a steel chassis. These controllers will require a power supply to
operate
Cable entry is made through the rear or through ‘knock-out’ pieces in both the top and
bottom of the case.
The enclosure design features earth braid termination springs providing an easy method
to terminate cable earth braid.

In the power supply version a visible lens on the front of the enclosure provides indication
of power to the door controller.
Adequate mounting space is provisioned allowing for easy installation.
High-quality pluggable ‘rising clamp’ style connectors are utilised throughout the product
for maximum reliability and to ease installation. All connections are marked by a
removable terminal label.
2.6
Door Controller – with Power Supply Unit
MICROgarde™ door controllers with power supply feature a high-quality, low noise fully
regulated 90 to 264 VAC switched mode 13.8 VDC power supply providing power to both
controller board and locks. The power supply is mounted within the enclosure and rated
at 3 Amps.
Provision is made for connection and charging of a 7 Ah back-up battery to allow
operation of the controller and locks in the event of power failure. Switching between
main power to battery power and back is seamless, requiring no user intervention. An
event is logged when main power fails.
TDSi does not supply the back-up batteries; these are to be sourced by the installer or
project company.
2.7
Door Controller – Memory
MICROgarde™ controllers are classed as intelligent, in that they store all card holders
and access rules allowing complete operation should communications to the host
communications server be lost. All door controller types feature as standard storage for
up to 1,000 events should this situation occur.
However, it is possible to configure the memory partition such that more space is
allocated for event retention by decreasing the space allocated for the number of card
holders.
Events are automatically uploaded to the host communications server upon
communications being restored. No user intervention is required.
The overall memory size is fixed and cannot be upgraded or expanded in any way.
Memory is battery backed so that all data is retained should power to the door controller
be lost.
2.8
Door Controller – Programming
Programming of the MICROgarde™ door controller is accomplished through use of the
EXguard PRO™ or MICROgarde™ access management PC software.
2.9
Door Controller – Inputs and Outputs
MICROgarde I™ controllers feature 4 inputs per door controller, 2 being used per
installed door for connection of a door contact and a request to exit button. The
remaining inputs are available for third-party equipment point monitoring. Inputs can be
used as either non-supervised or supervised in addition to being able to be configured as
normally open or normally closed.

Each MICROgarde™ door controller allows an additional expansion card to be fitted
providing further input and output capability. One types of expansion card is available.
4 additional inputs and 2 additional output relays.
Inputs can be used to perform secondary tasks within the access control system.
All relays are Form C with contact ratings of 2A at 30 VDC.
2.10 Door Controller – Reader Interface
MICROgarde™ door controllers feature numerous reader interfaces. These include:
Magnetic clock and data (ABA track 2 emulation)
Wiegand (26 and 37 bit)
TDSi Digital Infrared Reader (Microcard)
Any reader with one of the above mentioned reader interfaces can be connected to
MICROgarde™ door controllers. However, it should be noted that in the case of
Wiegand, the card number reported by the door controller may differ to that printed on the
card.
MICROgarde™ controllers feature a ‘self learn’ function that allows the controller to
discover the output format of any connected card reader.
