Correct Pairing Procedure

Aranet Pro/Pro Plus supports several types of sensors. To connect them to the system, the same steps apply for all types of sensors. Sensors can be paired one-by-one or in batches.

When pairing the sensor, it should be physically located within around 20 meters of Aranet PRO/PRO Plus.

• Open the battery compartment of the sensor, see the example image below. While holding with one arm the plastic cup, turn clockwise the main plastic body of the sensor (do not remove or twist the cable).

• Most other sensors have a visible battery compartment or screws on the body. Loosen the screws to take out the lid and expose the battery compartment. Take out battery(ies) from the sensor(s) you want to pair. If there are two batteries in the battery compartment, it is enough to take out one.

When pairing Aranet4 PRO sensor, make sure that “Radio” switch is in ON (upper) position:

Then log in to the base station WebGUI, using an account with Administrator rights. Explained here: Connecting to Web Interface.

In the graphical user interface of the Aranet base station, go to the SENSORS menu:

Choose the necessary measurement interval (10, 5, 2, or 1 minute) for the sensor. Next to begin pairing procedure click on PAIR SENSOR. 2-minute timer indicated by the closing ring is started:

Insert the sensor’s battery(ies) by observing the correct polarity. Refer to the datasheet of the respective sensor for information on supported battery types.

The red LED light will flash on the sensor. Three short flashes followed by a long flash will signal a connection failure; the pause between flashes will be the same. In case of successful pairing, the long flash will follow immediately after a short flash. Observing the LED light indications can save time while pairing sensors; however, Aranet Pro software will also display successfully paired sensors in the sensors list: new sensors are indicated by a green triangle. The sensor pairing process usually lasts 10-15 seconds, but can be as long as 30 seconds.

Each time a new sensor is successfully paired, the 2-minute timer is restarted. If sensor pairing was not successful within a 30-second period, take out the battery from the sensor, wait 10 seconds, and place the battery back to repeat the pairing process, or you may need to press the PAIRING button on the PCB plate of the sensor to initiate pairing, or get the device to be discoverable. When you finish pairing all sensors, press the STOP PAIRING button or wait for the timer to close the pairing process automatically.

After successful pairing, close the battery compartment of the sensor(s).

Now you can rename the sensor(s), set thresholds for alarms, add it (them) to favorites, etc. After completing your tasks, click the Save button for every modified sensor.

At this point, you have successfully paired your sensor/-s to the base station.

In case you would like to perform sensor pairing by using Aranet Cloud, then please refer to this topic: Base Management
