3. Product and functional overview
The Transponder Reader - TR22A01KNX/TR22A11KNX is an EIB/KNX wall mounting
device suitable to access control application.
This device can be used in any kind of building (Hotel, Hospital, Offices, Parking, etc..)
where the access control application is required.
The device is equipped with two binary inputs (potential free contacts) that can be used,
for instance, to control whether the door lock has been opened or closed or other
signals coming from external switches/contacts (i.e. windows, bathroom emergency
alarms, etc..).
The transponder reader is equipped also with two output relays which can be used for
any purposes, for instance in case of Hotel application to open the door or turning on
the courtesy light inside the room.
The product provides on the front side four LEDs in order to enlighten 4 icons to display
the following states (e.g. in case of Hotel management):
Access Allowed/Not Allowed
SOS request
Service Call (clean room, etc..)
Client status (“Busy room” or “Do not Disturb”)
The LEDs and icons can be configured in association with other alarms or events (see
LEDs signalling in the “Application Notes” included).
The transponder reader can reads cards or keys at a maximum distance of 30mm from
the front side.
The access control follows a sequence where the “Build Number” has been checked at
first, then the expiration data, next the password ID for client/guest/service identification,
then the enabled days of week and hours range. In case card reading pass all checks
the door is opened, the courtesy light inside is switched on and a specific 1 bit object
associated to the identified class of user is sent. At the same time the Transponder
Reader sends the access response to the bus in order to be detected and stored by a
visualization or management software..
The reader can identifies up to four types or classes of users through the reading of four
different ranges of passwords written in the cards created with the “Transponder
Encorder” (code: TE00A01USB).
This device provides also an alarm function by sending an “Alarm” object (1bit) to alarm,
for instance, a centralized visualization software (e.g. “eAccess” or “eHotel”) that a
power failure was occurred and then recovered next. This advice can be useful to
visualization and monitoring software to update some configuration data to the readers
and to the card holders or for other purposes.
The physical address, group address and parameters are assigned and programmed
with the ETS tool software. In order to commission the device, a PC with ETS2 version
V1.3 or higher is required as well as an interface to the bus, e.g. via an RS232 interface
or via a USB interface.
This device must be configured and loaded with the following application program:
