Versions for 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 knob cylinder
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 knob cylinder - 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 authorisation entitles a key to operate one knob cylinder.
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
knob cylinder (up to 60,000 individual authorizations).
Keys with toggle authorization can permanently engage a knob cylinder, hence
the door can be opened even without a key.

The four-eyes group is used to operate a knob cylinder 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 knob cylinder. Which
group is defined as the four-eyes group can be configured for each knob
cylinder.
In combination with a CX6934 IDS module, the knob cylinder 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 knob cylinder 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 restriction 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 knob
cylinder CX616x 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 knob cylinder (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 knob cylinders operated offline, there is an option to send the battery
status of the knob cylinders to the Keyvi management software. To do this, the
battery status of the 16 most recently operated locking units is stored on the key.
Four-Eyes-Group
Intrusion detection
system (IDS) group

CX6162/66 PRODUCT DESCRIPTION
7
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. A
prerequisite is that the key should have been prepared for writing the information
and the option Key feedback should be set in the knob cylinder.
Key Feedback can only be used with the transponder types MIFARE ®and LEGIC®
advant.
3.1.6 Battery management
The electronic knob cylinder CX616x 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).
Signalling happens in 3 phases:
The battery needs to be changed soon.
If an authorised key is held in front of the reading unit, then the engaging of the
knob cylinder is accompanied with flashing of red light (5 times) and 5 short
audible signals.
The battery needs to be changed.
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 knob
cylinder is delayed by 5 seconds, during which time the green LEDs flash.
The battery needs to be changed immediately.
If an authorised key is held in front of the knob cylinder, the locking authorisation
is no longer issued. The knob cylinder flashes 5 times in red accompanied by 5
short beeps.
The access data, the events log, the settings of the knob cylinder 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. If EM and HITAG1 keys are
also used with the locking system, then these keys can also be programmed using
the service unit.
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 an electronic component of the locking
system, 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.

4Assembly
4.1 General assembly instructions
Before assembling the CX616x knob cylinder in a fire/smoke-resistant door,
please check the fire certification to ensure conformity.
Carry out the assembly necessarily with the door open.
Ensure that the latches or seals fitted to the door do not hinder the proper
operation of the CX616x.
Ensure that the knob cylinder does not protrude and prevent the door from
swinging freely.
Before assembling the knob cylinder, always check if the components can
move freely.
After assembly, check the function with the door open.
4.2 Assembly
Insert the cylinder housing along with the electronic knob into the lock.
Tighten the fixing screw by hand, do not use a battery-operated screwdriver
with a high torque.
The cylinder body must not project outside its enclosing fitting by more than 1 to
3 mm, but it should not also be installed sunk in the upholstery.
The mechanical knob is assembled to the end of the cylinder housing and
secured using the grub screw. In the process, ensure that the axis of rotation,
as well as the seating of the knob have a flat surface, both of which need to
be flush with each other.

CX6162/66 COMMISSIONING
15
5Commissioning
5.1 Initial commissioning
To protect the battery from discharging during transport, the CX6162/66 is kept
in transport mode till the initial commissioning. There are two options of
changing over to the normal operating mode.
Option 1)
Turn the knob a few times to wake up the reading unit, till an LED starts
glowing.
Hold up the key in front of the reading unit only after this.
Option 2)
Remove the battery for at least 10 seconds and insert it again (see chapter
7.2.1 Replacing the battery, page 20).
Now you can continue with chapter 5.2 Managing the locking system.

CX6162/66 COMMISSIONING
16
5.2 Managing the locking system
The locking system can be managed using the Keyvi management software.
Before a locking system component can be used, it has to be personalized and
the settings have to be customized.
5.2.1 Personalization
Every door and key in the electronic locking system Clex prime should be known
to the management software for the respective locking system for subsequent
programming. This procedure is called customisation.
During customisation, the door or the knob cylinder installed inside is assigned a
Door ID (D-ID) and the key is assigned a Key ID (K-ID) by the management
software Keyvi.
5.2.2 Changing the settings
The following settings can be changed:
Authorisations (see chapter 3.1.1 Authorisations, page 5)
Time zones (see chapter 3.1.2 Time zones, page 6)
Time
Engagement time (defines the time for which the knob cylinder remains engaged
after holding up an authorised key, see chapter6.2 Opening and locking the
door., Page 18)
Wake-up sensitivity (see chapter 6.1 Automatic wake up, page 17)
Expiry date of a key (see chapter 3.1.3 Automatic expiry date, page 6)
Radio response of the knob cylinder (wake-on-radio mode)
The authorisations have to be changed first in the Keyvi management software for
the individual knob cylinders or groups of knob cylinders. The software
consolidates these settings into tasks, which then need to be transferred first to the
service unit or to ClexTouch. From there, they can be sent to the individual knob
cylinders.
If the knob cylinder is located in a Keyvi radio network, then the transfer can also
be done via radio.
For additional information refer to the documentation on CX6530 Keyvi
management software, CX6510 service device, and CX6522 ClexTouch.
5.3 Configuring the knob cylinder
Precondition: Orders have been created in the Keyvi management software and
sent to the service device or to ClexTouch.
Hold the service key in front of the knob cylinder to switch the knob cylinder
to the service mode.
Using the service device or ClexTouch, send the respective order to the knob
cylinder (see operating manual of CX6510 service device or that of CX6522
ClexTouch)

CX6162/66 OPERATION
17
6Operation
6.1 Automatic wake up
The knob cylinder is in sleep mode as long as it is not used. To check the
authorization of a key, it needs to be woken up from the sleep mode. This
normally happens automatically when a key is held in front of the reader unit.
If, however, the electronic knob cylinder has been woken up 24 times (for
example by metallic objects in the surroundings) without reading a key, then
automatic wake up is disabled.
In this case the knob cylinder has to be woken up manually.
Turn the knob a few times to wake up the reading unit, till an LED starts
glowing.
Hold up the key in front of the reading unit only after this.
Automatic wake up is enabled once again by reading an authorized key, but it
can also be enabled or disabled using the service unit CX6510.
The wake up sensitivity (that is the number of times the knob cylinder needs to be
turned to wake up the reading unit) can also be configured.
