FingerPrintScan System FPC 1381
– Technical Handbook
Version 2.00 page 5
4. Function Mode
The FPS-S enables control functions to be processed using the unique biometric
characteristics of individuals. The system uses the biometric characteristics of
fingerprints. The fingerprint is recorded
on a scanner using a “thermal line sensor”.
Recording is performed by noting temperature differences on the fingerprint,
evaluating the print and its unique characteristics (minutiae) and finally storing the
information in the system. If the print is recognised in further scan processing, then
attributed functions are carried out (e.g. opening doors, arming/disarming an IDS).
5. Modes of Operation
The system can be used in two basic modes of operation
Operation Mode 1 (BA1):
For general use without requirements or dependencies: For switching functions four
isolated switch relays are provided. Each relay can be programmed for different
operation modes.
Operation Mode 2 (BA2):
Specially design for arming/disarming intruder detection systems. The evaluation of
signals for the so-
called “inevitability” is guaranteed. In this operation mode relay 1 is
provided for the arming of an intrusion alarm control unit. The other three relays are
available for individual programming.
6. Fundamentals
The FingerPrintScan System consists of the P1381 controller and the P1384 / P1385
scanner. The system operates on 12 V. Communication between the controller and
the scanner takes place over an RS
– 485 data bus. Four two-way switch relays and
three 12 V outputs are provided for display purposes. The P1384 scanner has a
buzzer as well as 3 LEDs for displaying status. The P1385 scanner has a buzzer as
well as 2 multi-coloured LEDs for displaying status.
7. Data Protection
Fingerprints are recognised through their minutiae, distinctive points in the fingerprint
pattern (e.g. bifurcations, terminations). The system extracts such minutiae from each
print read and stores the position and angle of each. A reconstruction of the full print
using the minutiae is not possible, thus guaranteeing data protection and unlimited
use.
