Overview
1.2.1 Access Control
Each person who is to be allowed access is given a card (or key fob) with a unique number.
When the card is presented at a reader next to a door, the number is read and transmitted to
the MICROgarde controller to which it is connected. If that number is in the memory of the
controller, with permission to enter the door at that time, the controller operates a relay
which in turn unlocks the door for a pre-set number of seconds. The controller also records
the event, which is sent to the software event trail and logging.
EXgarde software is used to set up a system of up to 200 MICROgarde controllers. Once
the system is set up, the software can be closed down if required because each controller
contains all of the valid card numbers together with all the rules that govern access.
The software will also retrieve and display events as they happen. If events have occurred
while the software has been closed down, the software will retrieve them when re-started. If
a controller records 1000 events (programmable) while it is off-line, then the oldest event is
discarded to make room for each new event.
1.2.2 Doors and readers
There are 2 main types of MICROgarde controller: MICROgarde I and MICROgarde II.
MICROgarde I is a 1 door controller with 1-2 readers.
MICROgarde II is a 2 door controller with up to 4 TDSi readers or two non-TDSi readers.
A door can have a reader on both sides of the door. Because a card holder is given
permission (courtesy of his or her access level) on a reader-by-reader basis, a card may be
allowed access through a door in one direction only if required. Where a reader is fitted on
one side of the door only, opening the door from the other side may require the fitting of
suitable door hardware or an exit button.
1.2.3 Inputs and relays
You can reduce the number of doors controlled by a MICROgarde and thus use the spare
relays and inputs for monitoring other devices. An optional board can be added to each
controller that adds 4 more spare inputs and 2 relay outputs.
If required a MICROgarde can be programmed to be pure I/O and not used for reader and
door. A MICROgarde II with an I/O board fitted would provide 4 spare relays and 8 spare
inputs in total.
An input can be connected to another device that contains (or behaves like) a switch. For
example, a contact fitted to a window frame could be connected so that you could see in the
EXgarde software whether the window was open, and also see the times of opening and
closing.
A relay can be connected to another device for the purpose of turning it on and off in the
following ways:
From an instruction by the Operator using the software
Automatically when an input is switched on and off
Automatically according to a pre-set time pattern
Page 5 MICROgarde controller I and II 04.20.11.18
Page 8
1.2.4 Options
The simplest possible system, in addition to the PC running the software, would comprise 1
controller, 1 reader, one 12V power supply (for both lock and controller) and one electric lock
release. The following extras are available, some of which may be required depending on
site layout and cable distances:
Lock Power supply
We recommend the use of separate power supplies for locks. In most cases however, using
one supply for the controller and the lock(s) it controls will cause no problems provided the
supply has sufficient current output, and the cable distances do not result in significant
voltage drops. If in doubt, use one supply for the controller, and one supply for each lock.
Door sensor
Using a switch to detect when a door opens has two possible benefits:
It minimizes the length of time the door is unlocked after access has been granted. The
door locks immediately it re-closes - regardless of the "lock release time" setting.
The event list shows when doors open and close. If an exit reader or exit button is fitted,
the event list shows if the door is forced open (i.e. opens without either a card or an exit
button being used).
Exit button
Depending on the type of lock release, fitting an exit button may be the most convenient way
of letting someone out of a secured area if no exit reader is fitted. Pressing the button
causes the lock to be released just as if a card had been used.
Exit reader
If you want to monitor the whereabouts of all card holders, fitting an exit reader is necessary.
You can set reader properties so that you can see whether card holders are "On Site" or not.
Readers with keypads
There is always a risk that someone can gain access with a lost or stolen card, if the card is
used before it is deleted from the system. However, if a reader has a keypad fitted, then it is
possible to require a code to be entered as well as the card and this increases security
because only the rightful card holder should know the code for that card.
Alternatively, you can reduce security by using just a pin only code. It is possible to have
weekly schedules of card and pin; card only and pin only.

The MICROgarde controller is designed to be mounted on flat (or nearly-flat) surfaces while
allowing cables to pass underneath. Four screws and mounting pillars are required to mount
the chassis onto the wall.
The acceptable temperature range for the controller is -5°C to +50°C. The controller
generates some heat and the ambient temperature where the controller is installed may rise
without adequate ventilation.
WARNING! When installing the lid on a MICROgarde with PSU ensure the lip of the lower case
is visible, preventing the lid from lifting:

Cabling Requirements
All communications and reader cables should be in screened cable and at least two metres
long for full EMC protection and maximum reliability.
2.3.1 Choosing the correct cable
Note. TDSI recommends using screened cable throughout for ALL cables including door
sensors, exit buttons, inputs and lock.
Connections to the power supply and any readers MUST use screened cables. With
communications cables, you are strongly recommended to use a screened cable.
Table 1 lists the recommended cable types.

2.3.3 Grounding
Always ensure the MICROgarde chassis is connected to a GOOD earth grounding.
In general, the communication and other peripheral cable screens should be earthed at the
MICROgarde chassis ONLY. The one exception to this rule is if the item (e.g. reader, egress,
lock etc.) is mounted on an earthed metal surface. In this instance, earth the cable to the metal
surface and NOT at the MICROgarde unit. This prevents earth loops which can allow current to
flow along the screen wire causing interference.
Keep all unshielded cable runs and earth/drain wire “pig tails” as short as possible. To minimize
exposed earth braid, never remove more cable sheathing than necessary.
Figure 6 shows the correct way to feed cables around the slots in the chassis plate. It is important
that the cable screens are tightly gripped – a thin, single cable can be folded back on itself and
twisted to thicken it, or it can be wrapped round the metal between two slots.
Securing cables through the chassis plate

Page 15
Connections
CAUTION! Please read this section carefully as incorrect wiring could cause irreparable
damage to the controller and invalidate the warranty. Check all wiring before connecting
power to the unit.
2.4.1 Connecting Readers
The MICROgarde controller can be connected to any make or type of reader using the
following communication protocols:
Clock&Data (Magnetic)
Wiegand:
Standard 26 bit
HID 37 bit
Generic Wiegand variable up to 64 Bits
Note. TDSi readers such as the eXprox, eXprox VR, and TDSi MIfare have colour-coded wires
that match the MICROgarde connections overlay label.
To use 2 readers on each channel for In and Out readers on the same door, then you must
be using one of the following readers: EXprox, EXprox VR, Optica, Optica VR, Digital IR,
EXprox 2, EXprox 2K, EXsmart 2 or EXsmart 2K.
For readers 3 and 4 using EXprox and Digital IR, fit the extra brown wire to CLOCK, for
other TDSi readers please refer to its manual.
CAUTION! Use shielded cable for all readers.
2.4.2 Egress or Exit button
Note. If you have connected readers on both sides of a single door this option may not be
necessary.
Use switches with voltage-free contacts: a simple short triggers the egress function.
2.4.3 Door sensor
Use a door sensor if you want to know when the door is opened normally, forced open, or
left open too long. MICROgarde can be programmed to associate either an open or closed
circuit with the open/closed door position.
Use sensors with voltage-free contacts as a simple short triggers the function.

CAUTION! A suppressor MUST be fitted at each lock (see below). Two suitable
suppressors (1N4003 diodes) are provided with each MICROgarde controller.
For maximum reliability, we recommend the use of separate power supplies for locks. In
most cases however, using one supply for the controller and the lock(s) it controls will cause
no problems provided the supply has sufficient current output, and the cable distances do
not result in significant voltage drops. If in doubt, use one supply for the controller, and one
supply for each lock.
For each lock, allow 50% more than its stated rating. For example, if the lock has a rating of
500mA, use a 750mA minimum supply. If the lock has a higher current rating than the lock
relay (2A), use a secondary relay.
Always run the power to the lock in a separate cable.
Fit the supplied suppressor across the lock supply as close to
the lock as possible (NOT at the MICROgarde unit) with the
white band end connected to the positive side of the supply.
The supplied suppressors are suitable for DC locks ONLY.
– the suppressor must be connected across the two wires
Figure 7 shows the connections for a “fail-safe” lock, i.e. when the power is off, the door is
unlocked. Connect the supply of the lock across the N/O (normally OPEN) and the Com
(Common). When the relay is triggered to allow access, it supplies power to the lock.

2.4.5
Power Supply Connection
MICROgarde units without integral PSU
MICROgarde units with integral PSU
If you have purchased a MICROgarde unit without an integral power supply, you need to
connect the unit to a suitable PSU. This should be capable of supplying enough power for
the controller and its readers. In most cases, a 1A power supply is adequate. However, if
your installation consists of 4 Optica readers/keypads and a TCP/IP module, you should use
a 1.5A supply.
1. Connect the PSU to the MICROgarde’s 0V and 12V terminals using braid-screened
cable. Position the PSU as close as possible to the unit.
2. To minimize electrical interference, ensure that the MICROgarde and PSU are
grounded together: fasten the braid screen to both the main earth point in the PSU
and to the chassis plate of the MICROgarde.
3. Fit two suppressors across the mains input to the power supply. Suitable suppressors
are provided with each MICROgarde non PSU unit. These are 470 pF (pico-Farad)
Class Y disc ceramic capacitors rated at 240V AC.
(a) Appearance and dimensions of PSU suppressor and
(b) connection to PSU
A MICROgarde controller with integral PSU features a high-quality 3A power supply.
The lock power MUST be taken from one of the 1A fuses supplied on the fuse board and not
from the power terminals (7, 8, 9 and 10) on the MICROgarde controller. Failure to do so
may result in unreliable operation of the door controller.
Page 15 MICROgarde controller I and II 04.20.11.18
Page 18
PoE Power Supply
MICROgarde units with integrated PoE
These controllers have a 3A PoE module fitted which offers integrated battery charging with deep
discharge protection. The table below lists output currents from each of the different input classes
available:
Ref Class Output
PoE++ PoE 802.3bt 13.8Vdc, 3A
PoE+ PoE 802.3at 13.8Vdc, 1A
Although the module will operate from 802.3af source equipment this will provide insufficient
current for the controller and readers, it is recommended that 802.3bt is used as standard. When
installing the system observe the manufactures instructions for the source PSE equipment.
In the event of loss of the PoE source the green LED will turn off, if the system is connected to a
backup battery power will continue to be delivered from this. When installing the controller with an
SLA back-up battery the ferrite supplied should be fitted to the red and black leads with a single
turn, and secured with a cable tie:
The PoE module has no serviceable parts.
Page 16 MICROgarde controller I and II 04.20.11.18
Page 19
2.4.6 Communications
Earthing
The communications cable should be earthed on the incoming side only: the cable bringing
communications in from the administration computer or the preceding MICROgarde unit or
other Access Control Unit (ACU). The communications cable leaving the ACU should ideally
be taped off. (This prevents earth loops).
For RS485 termination, put the termination dip switches 1 and 2 ON. Do this only on the first
MICROgarde controller in the RS485 bus.
RS232 communication
Note. This method is only suitable if the administration PC is within 15m of the MICROgarde unit
and has a vacant COM port. If the administration PC is more than 15m from a MICROgarde unit
and you want to use RS232, you will need to use an RS232/RS485 converter. The TDSI RS232
to 2-wire RS485 Converter can be used for this purpose – part no. 5012-0013 (UK plug) or 50120014 (Euro Plug).
Create an RS232 link as described in Table 2 and shown in Figure 10.
Networking a PC to a MICROgarde using RS232
RS232 Pin MICROgarde pin Colour*
2 2 – RS232 Tx Red
3 1 – RS232 Rx Blue
5 3 - 0V Green
*TDSi RS232 comms lead (5002-1813) only.
Other manufacturers may use different colour coding.
To create a network, you can connect further MICROgarde units from connections 4 & 5.
These connections use RS485 but the MICROgarde has a built-in RS485/RS232 conversion
capability. Up to a maximum of 31 MICROgarde controllers can be added in this way.
Ensure you use a continual line or “daisy chain” with no spurring.
Note. 4-core RS485 cable is often cheaper and more easily obtained than 2-core. If you use 4core cable, connect the cores together in pairs, using one core from each pair – do not leave
cores un-connected.
RS232 communication: first controller within 15m of PC
RS232 communication: first controller more than 15m from PC

Connection via USB
TCP/IP Ethernet
For USB connection use TDSi’s USB to RS485 converter, part number 5012-0017.
MICROgarde network using USB-RS485 converter
You can also connect a MICROgarde to the administration PC via a TCP/IP ethernet
connection.
If you have not already done so, install TDSi’s TCP/IP module (Part No. 5002-1812) as
described on page 23 (alternatively other I/P converters such as the Lantronix UDS1100 can
be used – refer to the documentation supplied with the I/P converter).
Ethernet communication (a) TCP/IP module, (b) connections to
MICROgarde unit
Make a note of the MAC address to help with the EXgarde software controller set up.

2.4.7 MICROgarde Configuration
Rotary Dial switch
UID
Tamper spring
Battery
When you have completed the physical installation and connected the MICROgarde to
readers, switches and other devices, there are four further tasks to complete the
configuration of the unit:
Set the rotary switch
Make a note of the unit’s unique software identification code (UID).
Fit the tamper spring.
Enable the onboard battery.
All MICROgarde units must have a unique number. The first 8 units must be set to
addresses 1-8 and subsequent units set to position 9 which indicates that the UID of the
controller will be used for addressing purposes. The software will assign a unique unit
number for the additional controllers.
Make note of the Unit numbers given to your controllers to help in EXgarde software set up.
The UID is a unique number and should be noted for Software identification of the unit.
Using EXgarde software you will be required to type this UID in. A MICROgarde 1 has a
UID starting with 6, “6-xxx-xxx-xxx” and a MICROgarde 2 has a UID starting with 5, “5-xxxxxx-xxx”.
The tamper spring should be slotted onto the tamper spring switch SW1 located near the
Battery of the main PCB.
When you have completed installation and connection, it is essential that you remove the
battery tab. This enables the onboard memory, allowing the unit to store all information (for
example, access card details) should the unit lose power.

Inputs
Supervised use
A MICROgarde input is used to sense the state of a switch. An Input comprises of two
connections, which allows either an open circuit between the 2 connection points or a closed
circuit. The normal state for a MICROgarde input is “open”; by shorting the input across the
two connections, MICROgarde detects the change.
When the controller is configured to monitor and activate a door, two inputs are assigned:
Egress (Push to Exit) switch
If the egress connections are shorted the door is opened.
Door sense switch
Monitors the open or closed state of the door (the polarity of this switch can be
programmed).
If these inputs are not assigned to their normal function you can use them for other functions
such as controlling a relay: the input acts as a switch to trigger the relay.
Inputs also can be activated by other devices e.g. Passive Infrared sensors (PIRs).

Relays
Relays are often referred to as Outputs. They internally comprise an armature that flips from
one connection to another. This creates either a closed circuit or an open circuit.
Applying external power (relays do not provide power themselves) via the relay then applies
power from a PSU to other devices, e.g. a lock.
MICROgarde’s two relays are dry-contact changeover type, rated at 30V, 2 A. Connect the
lock to common and either N/C or N/O as described in Lock supply.
Devices which have inductive loads (i.e. anything with a coil, such as a secondary relay, bell
or motor) must be fitted with suppression at the device. If in doubt, fit a suppressor. A DC
device can be fitted with a diode (IN4003 or equivalent) as supplied with the MICROgarde.
The suppressor must be fitted at the coiled component terminal (secondary relay, bell,
motor, or lock), and not at the Controller circuit board terminal.

Installing an Input/Output Module
Software Configuration
You can add an I/O module to the PSU and non-PSU versions of the MICROgarde.
MICROgarde PSU version: the input/output module comes with 3 self-tapping screws
and 3 spacers for the metal cased MICROgarde. Fit these 3 screws through the I/O
board and then screw on the plastic spacers provided, before fitting and screwing to the
chassis.
MICROgarde non PSU version: the I/O module has a white plastic cover but a metal
chassis that has metal spacers already welded in position for the I/O board. Use the 3 x
standard M3 screws that are provided.
To fit the module:
1. Remove the connection label from controller.
2. Fit the I/O Module using 3 screws (labelled "1" in the picture).
3. Fit the ribbon cable (labelled "2" in picture).
The red wire of the ribbon cable should be adjacent to the tamper switch SW1.
4. Re-fit the connection label.
Installing an I/O module
Install the I/O before auto detecting the MICROgarde controller (see page Error! Bookmark
not defined.). The software then auto detects the I/O module.

Final Installation Checks
The following tests will confirm that the controller, reader(s), lock(s) and exit buttons are
correctly connected. Testing any door sensors requires the software to be running and will
be checked as part of the software setup (see page Error! Bookmark not defined.).
Note. If MICROgarde PC software is already running, disconnect the communications to the
MICROgarde controller by unplugging the 6-way connector.
17. Set the rotary switch of the unit to 0 (see below).
System checks and rotary dial switch setting
18. Power up the unit.
19. Set the rotary switch to the correct address: 1-8 or 9:
With EXgarde software, use 1-8 for the first eight units in a network. Set additional
units to 9.
With EXgarde PRO set all units to 9.
20. Check that the 5V On light (see 4 in Figure 19) illuminates and that the red LED on
each reader flashes continuously (2 flashes per second).
21. Present a card to any reader. The flashing rate of the red LED (on all readers)
changes to once every 2 seconds.
22. Put the unit into “installer mode”:
a. Carry out a hardware reset (see page 26).
b. Press the tamper switch down for 5 seconds.
c. Release the tamper switch for 5 seconds.
d. Press the tamper switch again down for 5 seconds.
e. Release the tamper switch again for 5 seconds.
f. Press the tamper switch down again for 5 seconds.
g. Release the tamper switch again for 5 seconds.
During this action the relay 1 will activate for 5 seconds and D13 red LED will light up
for 5 seconds.
23. Present the card again to any reader:
Both Relays 1 and 2 operate for 5 seconds. Any locks connected to these relays are
unlocked for 5 seconds.
The Relay 1 and 2 red LED indicators (D13 and D14) illuminate for 5 seconds
(regardless of the number of doors the controller will be controlling).
24. Press any Exit button. The associated lock is unlocked for 5 seconds.
25. Tests are now complete. Change the rotary switch to the required number.
26. Re-connect the communications link if necessary. If MICROgarde PC software is
running, the Tx and Rx lights will start flashing rapidly.

2.9.1 Hardware Reset
27. Exit installer mode by one of the following actions:
Shutdown and restart the software.
Validate a card using the software (see page Error! Bookmark not defined.)
Perform a hardware reset (see below).
28. In Normal operation mode:
The Reader LED flashes once every two seconds.
When a “non-valid” card is presented to a reader the reader LED lights up red for 5
seconds.
When a valid card is presented to a reader the reader LED lights up green for 5 seconds
and the corresponding lock relay will trigger.
To perform a hardware reset:
29. Turn off the MICROgarde unit.
30. Set the dial switch to zero (see Figure 19).
31. Switch the MICROgarde unit on.
32. Wait 20 seconds (watch for 4 green flashes on LED D8 followed by a pause and then
8 or 9 more green flashes).
33. Turn the dial back to the required unit number (1 to 8 or dial 9 for UID which selects
next available unit number).
After the hardware reset:
The unit’s memory is cleared.
The LED on any fitted reader will flash red, twice a second.
The first time you present a card to a reader it sets the reader into its ready mode and its
LED flashes once every 2 seconds. The second time you present the card, the reader’s
LED illuminates fully to indicate “access denied”.
The unit is ready to receive a reset and upload from the software and card validation.
