Borer
Data Systems manufacture a range of
CAN (Controller Area Network) access
control devices. Some of the benefits
of Borer and CAN are,
-
Power Over
LAN – This means we can send power
and data communications over a single
CAT5 cable. This means there is
no longer a need for bespoke cabling,
also, less hardware is deployed.
Note that CAN networks can also
be cabled in standard DeviceNet
cable, which also accommodates both
POWER and DATA, meaning no more
unsightly boxes mounted on the walls
near a door.
-
Many devices
can be installed on a single cable,
making it easier for the installer.
The devices are simply “daisy chained”.
-
No unsightly
control boxes, and much smaller
components, making Borer systems
much easier to install in modern
day “tight for space” buildings.
-
Higher level
of integration.
-
CAN uses Collision
Avoidance instead of Collision Detection,
to ensure data will always make
it to its intended destination.
CAN technology comes from the Automotive
Industry, where reliability is of
the upmost importance.
-
Plug and Play
– New devices can be installed onto
the CAN network, and there be no
need for special programming. The
new devices will download the set
of rules from the NIM. This makes
for faster installation, commissioning
and maintenance replacement.
-
CAN communications
are up to 100 times faster than
serial.
-
CAN devices
use considerably less power than
other systems, meaning lower running
costs, and less batteries to dispose
of.
-
Borer’s CAN
systems use memory from the Mobile
Phone Industry, hence why the sizes
of Borer’s systems are significantly
smaller then our competitors. This
makes for ease of installation and
maintenance into modern day buildings.
This section
explains 2 typical installation types.
The first is a single Access Control
site (A-tracs Express System), and a
multiple site system (A-tracs Enterprise
or Professional System). Note that the
Borer Systems have many modules to add
to this basic system demonstration in
this manual, for e.g. CCTV, ID Badge
production, secure locker access, visitor
management, alarm and intruder monitoring,
Attendance recording which includes
absence/attendance administration, evacuation
and roll call/muster and personal locater.
A-tracs Express –
This is a simple system, where the central
database, software and system controller
is on one PC. This would suit a small
to medium standalone site that doesn’t
have a high level of IT infrastructure.
Below
is a quick explanation of the parts
involved to make this system work. There
is also a brief explanation of each
scenario in the diagram.
A-tracs Express
Controller – This is the
computer that collects all the information
from the access control network. The
A-tracs Express Controller is responsible
for all the access control rules and
distributing them across the network
to the devices, we call this section
of the Controller a NIM (Network Integration
Module). In an A-tracs Express
installation, this computer will also
house the main database and the A-tracs
software.
Network Bridge (Controller
area network bridge) – This device is
responsible for translating the access
control CAN network messages to the
NIM. To do this the bridge translates
all CAN messages to IP messages across
the client’s local area network.
CAN Hub (Controller
area network hub) – This device is used
to re-transmit CAN messages, or split
the access control CAN network from
1 line into 2. This device is
often used to amplify the CAN messages
across long cable runs, or split the
single can line into 2 for ease of installation
LIM (Legacy Interface
Module) – This device is used to connect
non-CAN readers to the Borer CAN network.
This is used to you can use all types
of readers on the Borer system if the
customer does not want to change their
readers but do want to benefit from
the Borer CAN system.
SLIO (Serial Linked
Input Output Device) – This device can
perform operations based on an inward
or outward input. For e.g. When a user
swipes a card and creates an access
event, the SLIO can be told to turn
a light on, or you can connect the SLIO
to an smoke alarm, and if it smoke alarm
goes off, the SLIO can tell the system
to unlock all doors. The possibilities
from a SLIO are virtually endless.
Readers – Borer manufacture
a range of CAN based readers. These
readers can connect direct to the CAN
network without any LIM to translate
the signals. The reader is also
the door controller, meaning no other
controller boxes need to be installed.
A-tracs Enterprise and A-tracs Professional
–
This is a system where the NIM (Network
Integration Module), A-tracs software
and Central Database are separate units.
This system is often used in a multiple
site installation where central administration
is required and there is already a high
level of IT infrastructure. Multiple
sites can be connected in a variety
of ways, including the Internet and
private wide area networks. The main
difference between the Enterprise and
Professional versions is that Enterprise
allows unlimited users and uses a full
Installation of Microsoft SQL database,
whereas Professional uses a smaller
version of SQL database and allows 5
users of the A-tracs software.
Below
is a quick explanation of the parts
involved to make this system work. There
is also a brief explanation in the above
diagram. This diagram is the same as
the A-tracs Express site, except it
now has separated the role of the A-tracs
Express Controller into a NIM and a
Server, and the Site2 has a NIM that
reports its data back to the Server
at Site1 for storage. Note that all
of the computers on the corporate LAN
from any sites that have access to the
Server can view the A-tracs software.
Server– This server
is responsible for housing the central
database, and the A-tracs software.
The data is fed from the NIM to the
Server and stored for retrieval through
that A-tracs software.
NIM (Network Interface
Module) – This is the computer that
collects all the information from the
access control network and controls
the devices on the Access Control Network.
The NIM is responsible for all the access
control rules and distributing them
across the network to the devices.
In an A-tracs Express installation,
this computer will also have the A-tracs
software and central database.
Network Bridge (Controller
area network bridge) – This device is
responsible for translating the access
control CAN network messages to the
NIM. To do this the bridge translates
all CAN messages to IP messages across
the client’s local area network.

area network hub) – This device is used
to re-transmit CAN messages, or split
the access control CAN network from
1 line into 2. This device is
often used to amplify the CAN messages
across long cable runs, or split the
single can line into 2 for ease of installation
LIM (Legacy Interface
Module) – This device is used to connect
non-CAN readers to the Borer CAN network.
This is used to you can use all types
of readers on the Borer system if the
customer does not want to change their
readers but do want to benefit from
the Borer CAN system.
SLIO (Serial Linked
Input Output Device) – This device can
perform operations based on an inward
or outward input. For e.g. When a user
swipes a card and creates an access
event, the SLIO can be told to turn
a light on, or you can connect the SLIO
to an smoke alarm, and if it smoke alarm
goes off, the SLIO can tell the system
to unlock all doors. The possibilities
from a SLIO are virtually endless.
