This is a device that repeats the wireless signals so as to cover greater distances between the Access Point and the sensors. As soon as it
detects a wireless signal recognised by the network, it relays it.
In addition, it can be used to expand the number of sensors connected to the Access Point when these exceed 30 units, or if the distance
is greater than 30 m.

9.1 Parameters and functions
For each Router in the network, the information listed in the table can be
identifi ed from the notifi cation messages sent by the Router to the Access
Point, updated at intervals established by parameter HR_05 on the Access
Point (default 20s).
9.2 Binding the Router to the Access Point
•
Open the domain on the Access Point (press button T1 once).
•
Power up the Router.
•
The button on the Router does not need to be pressed, if the device is free
the procedure is activated automatically.
•
All the LEDs come on steady.
•
The Router searches for an Access Point to connect to (all the LEDs fl ash
every 20s).
•
Binding is successfully completed when only LED L1 remains on fl ashing,
the Router is now connected to the Access Point.
•
The Router address is set automatically and sequentially by the Access Point
when it's added to the network, assigning the network addresses from 200
to 247 for a maximum of 48 devices. This is valid for all Routers (including
the Router-Bridge and EP1 Router-Sensor, etc.). A maximum of 60 Routers
can be added.
•
The commissioning procedure is now complete and the system is ready to
communicate data.

NOTE: the binding operation on the Router may fail if:
•
Distances are excessive;
•
Infrastructure is present that prevents communication between the devices;
Each sensor installed should be visible to at least 2 devices, either Access Point
or Router. In the event of faults on the Router or additional barriers that block
the wireless signal, the sensor will fi nd an alternative route to communicate
with the Access Point.

not in confl ict with another device already associated with the network.
Binding the Routers
OPEN DOMAIN: press button T1 on the Access Point. LED L1 will start fl ashing
quickly (0.25s).

New devices can now be added;
Power up the Router and wait for LED L1 to fl ash;
CLOSE DOMAIN: After having added all the required devices, press button T1
on the Access Point to close the domain (LED L1 starts fl ashing again (1s) on
the Router and the Access Point.
