Safety
Thisequipmentmustbepoweredbyasupplywhichissuitablyinsulated
from the mains. The supply should be classed as SELV under the terms
of EN60950. You are recommended to use a 4910 or 4911 Power Supply
Unit.
The power supply must be connected to safety earth. A mains isolation
switch should be provided by the installer. Any third party equipment
connected must also be suitably insulated from the mains supply.
We also recommend that the 4101-2 Controller is connected to safety
earth via the power supply.
Controller relay outputs must not be connected to mains voltages.
Any fuses which are replaced must be of the recommended rating and
type.
Wiring connected by the installer must be adequate. The use of
inadequate wiring may present a fire hazard.
Except where specified the equipment is not suitable for outside use.
Some of the circuit boards provided contain lithium cells. These must
not be short circuited, dismantled or disposed of in fire. Consult local
regulations on disposal.
Lead acid batteries can present a variety of hazards. Use of batteries
other than those recommended should only be attempted by skilled
personnel. Lead acid batteries must not be short circuited, dismantled
or disposed of in fire. Consult local regulations on disposal.
Except where specified this equipment is not for use in safety critical
applications.

Chapter 2
The access control system
Introduction
The access control system is designed to be flexible in the way it is
configured for different applications and powerful in its function. Its
modular structure provides a cost-effective adaptable system.
The 4101-2 Controllers are at the heart of the system. They can be
used either with Cotag Access Control Software or with other
supervising software as part of an OEM system. They provide the
wide range of extra functions required by the users of modern access
control systems.
4101-2 Controller features include:
• the same controller for all tasks.
• up to eight access points per controller.
• a family of application modules to fit different application
requirements.
• distributed intelligence to provide system speed and integrity.
• fast and powerful communications structure.
• programmable logical control of input/output events.
• simple installation.
• automatic system configuration during commissioning.
Access control
An access control system uses an access token - usually a card - to
identify its holder and either grant or deny access to a door (or
“access point”). To achieve this, the number or code contained in the
card is read by a reader or reading head under control of an
electronic circuit known as a controller. The controller takes the
access decision (whether or not to let the cardholder through the
door) and operates the door using an electrical door lock mechanism

of some kind. One or more controllers are supervised by a computer,
usually a PC.
The diagram below shows a typical layout of the access control
system.
Computer
Printer
ControllerControllerController
Reading Head PINpad
Access tokens
The access control system can support all kinds of access token.
These will usually be proximity Cards or Tags using RF reading
technology to give Real Hands Free reading range.
Proximity Cards and Tags contain a custom micro chip and an
antenna system which enable the security codes stored in the chip to
be read by a reading head.
The system also supports the use of other card technologies such as
Wiegand, Magnetic Stripe or Bar Code and other identification
techniques such as PIN entry, fingerprint recognition or any other
biometric system.

The access control system
2-3
Readers and Reading Heads
Each different card or identification technology is associated with a
different reader.
The 4101-2 Controllers can drive the full range of Cotag Reading
Heads and Loop Antennas. The Reading Head consists of
transmitting and receiving antennas which are driven by a reader
module fitted inside the modular controller. When the cardholder
brings the card within range of the Reading Head the interrogation
signals from the Reading Head activate the card’s microchip. The
number stored in the card is then transmitted to the Reading Head.
4101-2 Controllers can also take inputs from any other card reader
or identification system which has a Wiegand or Magnetic Stripe style
of electrical interface. (Consult the chapter on swipe card modules or
call Technical Support if you need help with an interface.)
Controllers
The controller provides the intelligence and memory needed for the
access control decision, and the drive signals for the reader. It can
also receive input from monitored sensors and provide control of
other devices and systems via its relay outputs. This includes
activating a door lock and monitoring the door status.
One or more controllers are connected via a serial data link to the
supervising computer to make up the complete system.
The computer
The controllers in the system are all linked to a supervising
computer (or computers on a network). The computer is used to set
up the system database and download it to each controller. Most
decisions can then be taken by the controller without reference to the
computer. This means that the system can respond faster and will
continue to work even if the computer or its serial connections fail.
This technique is known as “distributed processing”.
The computer can also be used to monitor information about access
transactions, alarms and other messages from the controllers. Also, if
the computer is off-line, the controllers store this information for later
transmission.
4101-2 Controllers can be managed by a PC running the Access
Control Software or by any other computer system which has
software written to handle the Communications Protocol.

4101-2 Controller Installation Handbook
2-4
Door hardware
The access control system is completed by electric door locks and
sensors. Remarks here are confined to general observations.
Door locks must be carefully chosen to match the requirement and
the door structure itself. They are usually the only moving parts in
the whole system. Some designs of lock remain locked when the
power or the system fails (“fail secure”) and other designs unlock
when the power or the system fails (“fail safe”). It is very important to
ensure that the requirements of fire safety and the rules of the local
fire safety authority are taken into account.
Sensors can be used to show if a door is open or closed. They can
also be used to monitor almost any other part of a building or its
installed equipment to provide status information on the security of
the building or anything else.

4101-2 Modular Controllers
Each controller is housed in a metal case with removable cover and
internal chassis for ease of installation and maintenance.
The chassis carries a motherboard and provides slots for five modules
plus a 4210 RF Module for proximity cards.

The motherboard has a microprocessor circuit which manages the
modules, takes access control decisions and communicates with the
host computer. It also has enough RAM to retain all the access
control data needed for up to eight access points and 13,000
cardholders. An expansion connector for the 4105-2 Memory
Expansion Module enables the RAM to be increased to store up to
77,000 cards.
The 4210 RF Module is used in any 4101-2 Controller which also
contains Cotag reader modules. It occupies its own slot at the bottom
of the controller, smaller than all the other slots. If a controller is not
being used for Cotag readers (either because swipe cards are being
used or because the controller is only handling inputs and outputs)
then it does not need the RF Module.

The five other module slots can all take application modules
according to the needs of the installation:
Reader modules handling two readers (with PINpads if required) can
be fitted in any of the top four module slots. There are currently two
types of reader module:
• 4322 Cotag Reader module
• 4422 Swipe Card Reader module
Input/Output modules can be fitted in any of the top five slots. There
is currently one type of I/O module:
• 4253 Input/Output module 16/8 (provides 16 inputs and 8
outputs)
Up to two Communications modules can be fitted in any of the top
five slots. These are used to manage the controller communications -
see later for different configurations. There are currently three types
of Comms module:
• 4230 Communications module (the first Comms module in
systems with 17 to 64 Access Points)
• 4232 Communications module (for general use anywhere in
the system, and the first Comms module in systems with 1 to
16 Access Points)
• 4235 Communications module (the first Comms module in
systems with more than 64 Access Points)
