Issendorff LCN-AT2 User manual

Active transponder with two push-buttons - LCN-AT2
The LCN-AT2 has the form of a keyring. W
reader, it wakens up from its current saving mode and transfers its identification number
(ID) to the reader (per HF-signal, 866MHz).
The HF-transmitter in the LCN-AT2 can also
be activated manually by pressing a push-
button. The range to the reader LCN-ATW
will then be around 50m.
Each of the push-buttons can trigger its
own function in the LCN-system.

How it functions
The transponders (LCN-AT2´s) are activated automatically through the field of an LCN-
ATW, without having to press a button. For this it is enough to enter the detection zone
(max. 4m range) of the reading device. The LCN-AT2 answers the LCN-ATW with its own
ID-Nr. It adds its recognition (LF-ID) when sending to the reader, to which it answers.
When the transponder-ID is stored in the LCN-module of the LCN-ATW, the module will
then carry out the LONG-COMMAND. When the LCN-AT2 leaves the detection zone , the
module carries out the RELEASE-
COMMAND with a delay of approx. 10s.
Additionally the number of the transponder
is sent to the LCN-Bus, so that access
control systems can react to it.
The transponders (LCN-AT2´s) can send
wireless commands to the reader over 2
push-buttons, without having to be within
the set detection field of the antenna. When
the push-button A is pressed, the LCN-AT2
sends an information over the wireless
receiver in the reader to the Bus module,
that carries out the HIT function of the
chosen key in the transponder table.

The push-button B on the LCN-AT2 carries out the HIT function on the subsequent key.
The range with HF transfer (when pressing push-button) has a maximum of 50m in free
environment. Please make sure, that the commands on both push-buttons from all of the
LCN-ATW´s in the wireless receiving area are detected and redirected to the connected
Bus module - see also installation guide LCN-ATW.
(LF = low frequency with 125kHz, communication ATW -> AT2
HF = high frequency with 868MHz, communication AT2 ->ATW)
Further functions
The transponders have in addition to their active chip, a
second passive transponder chip.
The passive transponder is coded with the same ID, so
that it is possible to combine an access control system
with LCN-ATW and -ULT.
The range when detected by the LCN-ULT, is approx.
10-20mm - see illustration.
