DESCRIPTION
XTR-8LR-REP is an half duplex repeater ased on LoRaTM modulation providing an ultra
long range communication, high interference immunity , very high sensitivity and low
current consumption.
The repeater XTR-8LR-REP allows to enlarge the RF radio coverage etween the Aurel
XTR-8LR-4ZN or XTR-8LR-SOS keyfo (or XTR-8LR-ENC encoder) and the paired XTR-
8LR-DEC decoder.
85 - 264VAC power supply, IP55 enclosure and integrated antenna.
The device em eds a supercapacitor for temporary power supply ackup in case the
primary power fails.
OPERATION
The XTR-8LR-REP repeats the packets received from Aurel XTR-8LR-4ZN and XTR-8LR-
SOS keyfo s or Aurel XTR-8LR-ENC encoders.
In TRANSPARENT MODE (see "INSTALL THE XTR-8LR-REP" section elow) it repeats
packets received from all Aurel keyfo s (or encoders), in LEARN MODE it repeats only
the packets received from learned keyfo s or encoders (see "LEARN PROCEDURE"
section elow).
XTR-8LR-REP repeats the received packets with the following timing:
1. XTR-8LR-4ZN keyfo or encoder in "Without retry mode": 500msec after the last
received packet. This means that, if the user maintains the utton pressed on the
keyfo , the XTR-8LR-REP doesn't repeat any packet. When the user releases the
utton the keyfo stops transmitting and, after 500msec, the XTR-8LR-REP repeats
the last received packet. For this reason it is suggested to have rief utton
pressures on the keyfo .
2. XTR-8LR-SOS keyfo or Encoder in "With retry mode" : immediately after a
received packet. Note: the system works properly only with XTR-8LR-ENC firmware
version 1.9 or later.
To reach the decoder a keyfo can use more than one XTR-8LR-REP as relay (see Figure
1) o taining a multi-hop communication.
Figure 1 shows a schematic flow of packets in an example of installation with two hops
(XTR-8LR-REP) etween the keyfo and the decoder:
•the keyfo transmits a stream of packets during the utton pressure. When the
user releases the utton the keyfo transmits the last packet (Packet#1) and it
stops transmitting;
•the XTR-8LR-REP #1 repeats Packet #1 : it transmits the Packet #2 identical to
the Packet #1. This packet is received y the keyfo and y the XTR-8LR-REP #2;
•the XTR-8LR-REP #2 receives the Packet #2 and repeats it : it transmits the
Packet #3 identical to the Packet #1. This packet is received y the XTR-8LR-DEC
and y the XTR-8LR-REP #1;
•the keyfo uses the Packet #2 as acknowledge packet;
•the XTR-8LR-DEC receives the Packet #3, activates the output and transmits the
acknowledge packet (Packet #4) that is received y the XTR-8LR-REP #2;
• XTR-8LR-REP #1 doesn't repeat the Packet #3 (and in a similar way the XTR-8LR-
REP #2 doesn't repeat the Packet #4) ecause that packets are identical to an
already received packet y the repeater (respectively Packet #1 and Packet #2).
As you can see from the Figure 1 and related description, the keyfo only knows that the
Packet#1 is received y the closer XTR-8LR-REP and it doesn't know if the command is
really received (after one or more hop) y the XTR-8LR-DEC.
For this reason the keyfo never knows the status of the output on the decoder
therefore it always shows the reception of the ack packet with the GREEN LED ON for
600msec even if the decoder output is set in ista le mode.
In a similar way the encoder always shows the reception of the ack packet with the ACK
RECEIVED pin ON for 100msec (even if the decoder output is set in ista le mode and
the output has een deactivated).
During the installation it is possi le verify the RF link etween the XTR-8LR-REP and
another XTR-8LR-REP o the XTR-8LR-DEC (see "RADIO LINK TEST" section).
Note: the RF link test works properly only with XTR-8LR-DEC firmware version 1.9 or
later.
INSTALL THE XTR-8LR-REP
This symbol indicates a possibly dangerous situation
CAUTION: risk of injury by electric shock. A licensed electrician with
knowledge and understanding electrician systems and electrical safety should
complete the electrical installation.
1. Turn the screws on the housing into position 0 (see Figure 2.1) and remove the
cover.
2. Secure the housing on the wall using four screws (Ø4 mm max.), see figure 2.2.
Make sure the screws are suita le for use with the given type of wall.
3. Shut off the main circuit reaker of the uilding for safety during the installation
and ensure the wires are not short circuited during the installation.
4. Use a multicore ca le with 2 cores of section from 1.5mmq to 2.5mmq. The
maximum external dimension of the ca le must e in the range 6 - 12mm.
5. Insert the multicore ca le in the gland (see figure 2.2).
6. Insert each core of the ca le on the 230VAC connector and tighten the screw (see
figure 2.2). ATTENTION: when carrying out installation work, always
ensure that the connecting cable is not damaged or crushed.
7. Select the mode of operation through the TRANSPARENT/LEARN MODE DIP
SWITCH (see figure 2.3): if the dip switch is in LEARN MODE position the XTR-8LR-
REP works in LEARN MODE, if the dip switch is in TRANSP. MODE position the
device works in TRANSPARENT MODE.
8. Move the ON/OFF DIP SWITCH to the ON position.
9. Remove the BATTERY ENABLE JUMPER (see figure 2.3) if you do not need the
temporary supply ackup in case the primary power fails.
10. Restore power at the main circuit reaker. DANGER : touching live parts
can result in an electrical shock.
11. If the device works in LEARN MODE, save the keyfo s on the XTR-8LR-REP
through the LEARN PROCEDURE (see section elow).
12. Perform the Radio Link Test (see section elow) to verify the RF link etween the
XTR-8LR-REP and another XTR-8LR-REP or XTR-8LR-DEC.
13. Replace the cover and turn the screws into position 1 (see Figure 2.1).
LEARN PROCEDURE
1. Press and release the LEARN BUTTON (see figure 2.3).
2. The LEARN LED (see figure 2.3) links quickly for 10 seconds.
3. Within this time press a push utton on the keyfo : the LEARN LED stays on for 1
second to confirm the learning of the keyfo .
4. Repeat the procedure from point 1 to 3 for all keyfo s you need to learn.
Note: on the XTR-8LR-REP it is necessary to learn all the keyfo s learned on the
decoder.
Note : the learn procedure works only if the LEARN MODE is set.
MEMORY ERASE PROCEDURE
1. Press and release the LEARN BUTTON.
2. The LEARN LED links quickly for 10 seconds.
3. Within this time press the LEARN BUTTON again and maintain it pressed. The
LEARN LED turns ON and, after 5 seconds, it turns OFF. At this time release the
LEARN BUTTON.
4. The LEARN LED links 5 times to confirm the memory erase.
Note : the memory erase procedure works only if the LEARN MODE is set.
RADIO LINK TEST
Before performing the radio link test it is necessary to register on the XTR-8LR-REP a
keyfo already learned on the decoder XTR-8LR-DEC:
1. Press and maintain pressed the TEST BUTTON (see figure 2.3).
2. After 5 seconds the TEST LED (see figure 2.3) starts linking then release the
TEST BUTTON.
3. During the TEST LED linking (10 seconds) press a push utton on a keyfo
already learned on the decoder: the TEST LED stays on for 1 second to confirm the
registration of the keyfo .
At this point it is possi le to perform the link test etween the XTR-8LR-REP and another
XTR-8LR-REP or the decoder:
1. Press quickly the TEST BUTTON.
2. When the TEST BUTTON is released the TEST LED starts linking.
3. If the RF link is OK the TEST LED stops linking and stays ON for a out 2 seconds.
If the RF link is NOT OK the TEST LED continues to link for a out 3 seconds.
If in the installation there are more than one hop (XTR-8LR-REP) etween the keyfo
and the decoder it is suggested to start the installation from the XTR-8LR-REP closer to
the decoder and proceed with the other XTR-8LR-REP.
With reference to Figure 1 proceed as follows:
1. Install the XTR-8LR-REP #2 closer to the decoder.
2. Perform the RF link test etween the XTR-8LR-REP #2 and the decoder.
3. Install the XTR-8LR-REP #1 and perform the RF link test etween the XTR-8LR-
REP # 1 and the XTR-8LR-REP #2.
