3Product description
3.1 Functional description
The electronic door handle CX6172/4 is a product in the Clex prime system. The
reading unit, the communication electronics, the mechanical system and power
supply, are integrated within the door handle.
Different transponder carriers can be used as key in the CX6172/4, for example,
ISO card or key fob.

Versions for HITAG 1, MIFARE®and LEGIC ®Transponder can be supplied
3.1.1 Authorisations
There are up to 296 groups in the Clex prime locking system. If the door handle
is a member of one or more of these groups, then all those keys that are also
members of this group are authorized to open the door handle - provided the key
authorizations are not restricted by time zone settings.
In addition to the normal groups, there are 5000 other groups in the Clex prime
locking system. Each key can be a member of up to 16 of these other groups.
An individual authorization entitles a key to operate one door handle. Depending
on the type of key (writable, not writable), the individual authorizations are either
stored on the key (up to 16 individual authorizations per key) or in the door
handle (up to 60,000 individual authorizations).
Keys with toggle authorization can permanently engage a door handle, hence the
door can be opened even without a key.

The four-eyes group is used to open a door handle only when two different keys
are held up, out of which one should be a member of the four eyes group and
the other should have normal authorization for the door handle. Which group is
defined as the four-eyes group can be configured for each door handle.
In combination with a CX6934 IDS module, the door handle can be used to
enable and disable the intrusion detection system (IDS). To do this it is necessary
to define a group (IDS group) in the door handle that is authorized to enable /
disable the IDS.
In addition, a firefighters group can be defined, which is always authorized to
open the door regardless of the status of the intrusion detection system. In
contrast to the group access rights of the fire brigade, the switching status of the
intrusion detection system is first queried for all the other group access rights
before granting the access right.
3.1.2 Time zones
You can restrict the locking access right in terms of time by using a time zone.
The time restrictions along with the locking authorizations are programmed in the
key in the Clex prime system.
The following time restrictions are possible:
Total interval
Day interval
Weekly schedule
Holidays
Special time zones
For detailed information on the different time zones, please refer to the Keyvi
software manual.
3.1.3 Automatic expiry date
Using the automatic expiry date, it is possible to restrict the validity of a key
regardless of the time zones applicable for the key.
For detailed information on the automatic expiry date, please refer to the Keyvi
software manual.
3.1.4 Radio network
If a corresponding radio network is installed in the building, then the door handle
CX6172/4 can be integrated with this network. The following functions can be
then be executed via radio:
Programming access rights
Changing access rights
Configuring time zones / timer circuits
Reading event log
Engaging the door handle (for the duration defined by locking time)
Viewing battery and maintenance messages
Reading the battery value
FW update
3.1.5 Key feedback
Even for door handles operated offline, there is an option to send the battery
status of the door handle to the Keyvi management software. To do this, the
battery status of the 16 most recently operated door handles is stored on the key.
The battery status information is sent to Keyvi and deleted from the key if the key

is read by an automatic programming terminal or a programming station. The
prerequisite is that the key should have been prepared for writing the information
and the option Key feedback should be set in the door handle.
Key Feedback can only be used with the transponder types MIFARE ®and LEGIC®
advant.
3.1.6 Battery management
The electronic door handle CX6172/4 comes with a battery management system,
which indicates the need for battery replacement by means of a visible and audio
signal, when the battery power reduces (capacity loss) during the final 1,000
operations of the battery (see chapter 7.2.17.2.1 Battery Replacement).
The signal is given out in two phases:
The battery needs to be changed soon.
If an authorized key is held in front of the reading unit, then the engaging of the
door handle is accompanied with flashing of red light (5 times) and 5 short
audible signals.
The battery needs to be changed immediately.
If an authorized key is held in front of the reading unit, then the red LEDs flash (5
times) accompanied by 5 short audible signals. The engaging of the door handle
is delayed by 5 seconds, during which time the green LEDs flash.
The access data, the events log, the settings of the door handle and the time are
stored on non-volatile memory and thus retained even when there is no power
supply, for example, when changing the battery or if the battery discharges
completely. The time is written to the non-volatile memory once every 30 minutes.
If the power supply remains off, then the clock comes to a standstill after a few
seconds and starts running from the last stored value onwards after the power
supply is restored.

3.6 Management accessories
The components of the Clex prime system described below are used to manage a
Clex prime locking system.
3.6.1 CX6530 Keyvi management software
The locking system can be managed centrally and conveniently from the PC using
the Keyvi management software for Clex prime. Even complex locking programs
can be easily created, monitored and maintained using the software.
3.6.2 CX6510 Service device
The CX6510 service device is used for programming the locking system.
Information can be exchanged between the Keyvi management software and
locking units using the service unit. The information includes, for example,
authorizations, events or settings for the locking units. In case of EM and
HITAG1, the keys can also be programmed using the service device.
3.6.3 CX6522 ClexTouch
ClexTouch is software that runs on handheld computers or laptops with Windows.
It can be used to conveniently configure the locking system and (along with a
corresponding wireless USB stick) and the relevant data can be sent directly to all
the locking system components of Clex prime that are provided with a radio chip.
3.6.4 CX6520 Programming station
The programming station is an optional addition to the Keyvi management
software and the CX6510 service device in order to conveniently program the
key. In conjunction with MIFARE®or LEGIC ®transponders, the programming
station is always required to program the key. The programming station is
connected to the PC using a USB cable.
3.6.5 Special keys
Using the service key, a user identifies himself as an administrator of the locking
system. If this key is held in front of a locking system component, then the
respective component goes into service mode, where it is possible, for example,
to create or change authorisations, make settings or to read the event log.
A sub-service puts an already personalized locking unit into service mode. These
sub-service keys have authorization only for certain areas or for specific times (for
example, for a locking system with several houses and individual management).
Sub-service keys cannot be used to customise brand new locking units for the first
time. Only existing customised locking system units can be set to the service
mode.
