BASICS
Technology
„Biometrics“ refers to all kind of methods for
uniquely recognition of humans based on
one or more specic physical or behavioural
characteristics. The more unique those char-
acteristics are, the more they are applicable
for denite identication.
The oldest of all biometric methods is the
nger print identication, the so-called
dactyloscopy (greek. dactylos „finger” and
scopein „view”).
1896 in Argentina the dactyloscopy was intro-
duced country wide for criminal investigations.
Nowadays these methods become more and
more accepted as access control method.
A biometric system uses three components,
the sensor, the trait extraction (enrolment)
and the comparison.
The sensor sends as result a ngerprint tem-
plate. This template is an extract that is ad-
justed for optimal results. After the enrolment
the template is digitally encrypted and stored.
It is not possible to re-construct a complete
image from the template.
While using the biometric system, the stored
template will be compared to the current one.
If the matching rate is within certain toleranc-
es, the template will be accepted as valid.
The most signicant quality and reliability traits
of a biometric system are its failure rates: The
False Acceptance Rate (FAR) and the False
Rejection Rate (FRR).
More critical for consumer applications is the
FAR value. It is more dangerous when an un-
authorized person gets access than the rejec-
tion of authorized persons.
Besides a quick algorithm the sensor is the
most important part for the reliabilty, speed
and security of the biometric system.
The BAC-20 / BAC-40 is equipped with a high
performance sensor using the latest available
technology. It is a so-called active capaci-
tive hybrid sensor. This sensor doesn’t take
a “picture” of the nger surface, it measures
the conductivity of the saline layer below the
dry epidermis. Since the young skin is “build”
there, the skin ridge pattern is exact the same
than on the surface. Therefore this sensor
type is more applicable for children with soft
and people with dry and horny skin, can also
handle small injuries like scratches or cuts.
Furthermore the sensor can recognize replica
ngers
In comparison to swipe sensors, at which the
nger must be drawn with the same speed
and accuracy at any time over the sensor,
the handling of a atbed sensor is as easy as
pushing a simple button.

BASICS
Applications
BAC-20 / Easy Home Basic
Biolock Products have been developed for
Home and Ofce applications as well as the
automotive industry. The approval regulations
are much stronger than for domestic applica-
tions, particularly with regards to more inten-
sive environmental impacts, such as sunlight,
moisture or temperature uctuations.
As our products meet those requirements,
they are most suitable for domestic usage.
To use the Easy Home Basic you need to in-
stall an electromechanical door locking sys-
tem. The most popular method is an electric
strike, the most elaborate seems to be an in-
tegrated motorized door lock. Both methods
differ not only in security level, but also in cost
and installation effort.
Every average DIYer might install an electric
strike. If necessary, consult an expert.
Various kinds of locking systems can be con-
nected to the Easy Home Basic. In case that
large electrical loads must be switched, heavy
duty relays can be integrated in-between. For
example sliding doors, garage doors, shutters
etc.
BAC-40 / Easy Ofce
As explained before, the Easy Ofce meets
the same requirements as the Easy Home
Basic. The system is well protected against
environmental inuences and it is designed
to consume only a minimum of battery res-
sources in stand-by mode.
In addition to the basic functions of the Easy
Home basic, the Easy Ofce is also able to
save event les which can be used for ac-
cess control. These so called Logles can be
downloaded with a portable programming unit
(BMT-215U/40), which can be ordered sepa-
rately.
The Easy Ofce can be used for every kind
of premises, no matter if at home or in small
ofces. With the BMT-215U/40 you are able
to make further modications in the basic set-
tings e. g. controlling OUT-1/OUT-2 or chan-
ging the relay times.
In many cases, the BAC-40 will be used as
additional door application for the BAC-400, it
consists of BAC-40 & BMT-215U/40.

Safety (Protection against manipulation).
If you connect the reader and controller the
rst time, they exchange a numerical code
which contains 12 gures. This code is assi-
gned by the controller and stored as long as
the units are paired.
If the original reader is replaced by another
one, all formerly stored templates will be
deleted. The controller will assign a new
code to the connected reader and you have
to enrol the ngerprints of the authorized
persons again.

The controller of BAC-20 and BAC-40 con-
tains two independently adjustable Outputs
(Out 1 & Out 2, see adjoining g.), as well as
1 Input to connect alarm-/door sensor (Sen-
sor Switch).
Furthermore you can set the BAC-40 (in con-
junction with BMT-215U/40) to different Out-
modes, so that the outputs can be variably
switched.
General information.
The BAC-20 generally contains 2 Outputs.
In factory setting mode, the DC-mode is ac-
tivated, so that e.g. 2 electric strikes can be
operated. Additional to this, you have the pos-
sibility to change the system into Relay mode
(see adjoining g.).

If you want to upgrade the BAC-40 to a BAC-
400, you have to change the System ID at the
outdoor unit (BMR-207) before installation.
The idea is that if you want to provide several
doors with the BAC-40 in consumption with
the BMT-215U/40, the programmer should
have the possibility to identify which unit is
now connected and to enable the recogniti-
on of the individual logles after downloading
them. Please note that it is very important to
use different system ID‘s for each BAC-40.
The factory default for the System-ID is 1. You
have 15 different adjustment possibilities for
the system ID‘s (see below). For further infor-
mation, please refer to the BAC-400 instruc-
tion manual.

It is important to understand how the system
works and how the ngerprints will be regis-
tered correctly, to make the utilisation as sim-
ply as possible.
Fingerprints will be stored as so-called “tem-
plates” in the memory of the control unit. It is
not possible to re-construct complete nger-
print images from the templates, but to com-
pare two templates with each other.
BAC-20
The BAC-20 stores the ngerprints in the or-
der of their registration until 100 templates
have been stored. You can not delete single
templates but only all templates at once.
BAC-40
With the BAC-40, the ngerprints can only
be deleted directly through the controlbox if
this is setted to Basic mode (delivery status).
Please note that this adjustment can be mo-
died to Plus-Mode by the optional portable
programmer. As soon as the settings have
been changed to Plus-Mode the pushbuttons
can‘t be operated any more. All modications
can then be done by the programmer only.
IMPORTANT!
The BAC-20 and BAC-40 have got a storage
capacity of 100 templates. In case that this
amount is reached, you will hear an alert si-
gnal if you try to register a new ngerprint. If
you insist on registering this ngerprint, you
have to delete all templates. (Except BAC-40
in conjunction with BAC-400).
Registering new ngerprints.
To use the lower push button (M) on the
controlbox, you need to use an item like
a needle, paper-clip or a similar ne and
pointed item.
Press the M button shortly until a
signal appears.
Now, all 3 LED‘s will start ashing
(red and blue). After a further signal
sound, the red LED (P/W) will start
to glow constantly.
Now please open the cover of the
outdoor unit (reader) and put your n-
ger (as described on page 14) shortly
on the sensor surface. After that you
will hear a short signal sound which
conrms the registration of your n-
gerprint.
The registration has been completed
after some further sounds and if no
LED is glowing any more.
