1INTRODUCTION
1.1 IWAC Display v3
IWAC Display v3 from Zennio is a KNX interface presented as an access control
system to rooms or other parts of the installation through reading ID cards.
The most notable features of this device are:
Access control to rooms using cards with NFC (Near Field
Communication) technology of MIFARE DESFire and MIFARE Classic
types.
2.4-inch OLED display with 128 x 64 pixels resolution.
Multilanguage.
Buzzer for an audible acknowledgement of user actions (with the possibility
of disabling it by object).
Encrypted communication with Securel v2 for door opening.
Communication with Z-Access for the management and monitoring of
accesses.
3 touch buttons, which can operate as individual control.
Possibility of locking / unlocking the touch panel through binary object.
Possibility of setting a press detection delay.
Two analogue/digital inputs (for motion detectors, temperature probes,
additional switches, etc.).
Heartbeat.

1.2 ACCESS CONTROL SYSTEM
The following figure shows the main elements involved in an access control system
and the interactions between them:
Figure 1. Access control system elements.
IWAC Display v3 (In-Wall Access Control): NFC reader for access control
that is installed outside the room.
Securel v2: final element acting on the lock when granting access from
IWAC.
In the idle state, Securel v2 will keep the electric strike locked to prevent the
door opening. When the Open command is correctly received from IWAC
(access granted), Securel v2 will release the lock for a while to open the door.
BMS (Building Management System): computer system that assumes the
integral automation of the building.
Z-Access: application that allows employees to record access cards. In
addition, by means of a specific module of the BMS system, permits the joint
coordination of the different IWAC and the notification of certain events.
NFC card: passive element for accessing to certain rooms. IWAC Display v3
is compatible with two types of cards: MIFARE DESFire and MIFARE
Classic.

As indicated before, for security reasons, the communication between IWAC and
Securel v2 is encrypted.
Both IWAC and Securel v2 are connected to the KNX bus.
The data used by the system to allow or deny the access are:
Groups: sets of users or cards with the same access level. The groups
available are:
➢Guest
➢Visitor
➢Staff
➢Management
➢Service
➢Cleaning
➢Maintenance
➢Security
Card Identifier: unique NFC card identifier.
IWAC Display v3 Identifier: unique IWAC Display v3 identifier.
When recording data access to a card, the Z-Access application offers two alternatives
to the employee:
Associate the card with a specific group: the identifier of the selected
group will be recorded in the card. This option only supports DESFire cards.
Associate the card with a specific IWAC Display v3: the identifier of the
IWAC Display v3 will be recorded in the card (see section 2.5). Any card
associated with a specific IWAC Display v3 will be also associated with the
group “Guest”.
Any IWAC Display v3 has a unique identifier set by parameter. And it will gran or deny
the accesses according to its lists:
White list: groups with access granted. This list is set by parameter (see
section 2.5). In addition, IWAC Display v3 allows access to all the cards
associated with its identifier.

Black list: groups or cards with access denied. This list is set in Z-Access
and transmitted to IWAC Display v3 through the KNX bus.
The black list takes precedent over the white list (see examples below).
Note: an IWAC Display v3 that has the "Guest" group in its white list will allow access
to any card associated with any specific IWAC Display v3, so it is a configuration
intended for access control of common areas.

1.3 INSTALLATION
IWAC Display v3 connects to the KNX bus through the on-board KNX connector. This
device requires an external 24V DC power supply.
Figure 2. IWAC Display v3
The main elements of the device are described next.
Programming button (3): a short press on this button sets the device into
the programming mode, making the associated LED (2) light in red.
Note: if this button is held while plugging the device into the KNX bus, the
device will enter into safe mode. In such case, the LED will blink in red every
0.5 seconds.
Inputs (4): input ports for the insertion of the stripped cables of external
elements such as switches / motion detectors / temperature probes, etc. One
of the two cables of each element need to be connected to one of the slots
labelled “1” to “2”, while the other cable should be connected to the slot
labelled as “C”. Note that all the external input devices share the “C” slot for

one of the two cables. Please secure the connection by means of the
onboard screws.
Auxiliary power supply (8): external power of IWAC Display v3 is supplied
from Securel v2 (see Figure 3).
Encrypted communication port (9): input port to connect with Securel v2 to
make it possible the communication between both devices.
Figure 3 shows a connection diagram of IWAC, Securel v2, power supply and electric
strike:

For detailed information about the technical features of the device and for safety
instructions or about the installation process, please refer to the corresponding
Datasheet, bundled with the original package of the device and also available at
www.zennio.com.

1.4 START-UP AND POWER LOSS
After the device start-up, it requests date and time through the object “Request Date
and Time”. The group address of this object is the one that must be indicated in Z-
Access to respond to the request.
For proper operation of the buttons, it is recommended not to be pressing them during
the initialization, either after programming or after connecting the external power
supply.
On the other hand, a KNX bus power failure does not imply any change in the
device status since it has external power supply. Therefore, the device will continue
operating normally, although, of course, there will be no communication with the KNX
bus.
