eKey Fingerscan Access Control System Operating Instructions Manual page 8

General
Please read carefully the provisions below before starting to wire the system:
The connections of the devices are NOT protected against reverse polarity! Incorrect
wiring of the devices can result in them being damaged beyond repair!
Only trained and qualified electricians should carry out electrical wiring of the units
and connection to the mains grid!
Lay the connecting cable between the ekey home CP (control panel) and the ekey
home FS (finger scanner) separately from any 230 V or 380 V mains voltage cables
in the house. The connecting cable carries low voltage signals that can be interfered
with by current-carrying mains voltage cables in the vicinity.
6.2 SECURITY AGAINST MANIPULATION
Your ekey home system consists of 2 electronic devices
the ekey home finger scanner
the ekey home control panel
The ekey home finger scanner is typically mounted in an outdoor environment and therefore accessible to
everyone. In order to avoid external tampering, which could theoretically result in an unauthorized
access, your system is equipped with below listed security features:
The ekey home control panel has to be mounted in a secure area. The switching actuator (relay
output) to operate a motor locking system is positioned on the control panel.
System changes (fingerprint enrollment, etc.) can only be made via the ekey home control panel
situated in a secure area.
The access to the menu in the ekey home control panel is secured with a security code. This is an
additional obstacle within the system for unauthorized users.
The finger scanner is connected to the control panel by a data line. The communication between
both components is encrypted.
The finger scanner and the control panel are "married", i.e. they have been coupled during the
initial start-up. When replacing a device, a new coupling must be done via a specific key
combination on the control panel mounted in the secure area). Otherwise no access will be
granted.
Operation and data monitoring
Your ekey home finger scanner
operation data. If the system identifies inconsistencies, then the finger scanner will be recalibrated
automatically. This calibration procedure takes 3 to 5 seconds and can be followed via the LED signals
sequence (see section 7.3). These inconsistencies can be caused by:
abnormal electrostatic discharges (ESD),
abnormal electromagnetic interference fields.
It is not possible to operate the finger scanner during the calibration process. The device resumes its
normal operation after the calibration process is over.
