5.2.5.
User terminal address setting
Once the keyboard has been connected to the device, run the following procedure:
1)
Press and hold [UP]+[DOWN]+[ENTER] at the same time for at least 3 seconds to enter configuration mode. A
mask is displayed with the cursor flashing in the top left corner.
2)
Press [ENTER] once to modify the address of the terminal (display address setting). The cursor will move on
the address field.
Press [UP] or [DOWN] to select the required value of the address and then press [ENTER] again to confirm.
The value will be saved in the permanent memory of the terminal.
3)
The appearance of the next mask indicates that the keyboard address has been set.
4)
If an empty mask or a mask showing "NO LINK" appears after pressing [ESC], it means that the keyboard is not
communicating with any boards. It is necessary to set the address of the board or configure the local network (LAN).
ATTENTION
This is a time procedure; hence if the parameters are not set in a few seconds, the display turns off. In such case, repeat the
process.
5.3. REACTIONS TO ALARMS WITHIN THE LAN NETWORK
Some events cause reactions in all the units connected to the LAN network of the unit where the event itself occurred. These reactions are aimed at
preventing the formation of gas build-up.
The units not in alarm condition will show this reaction through the flashing of the Active Functions mask, to indicate that the behaviour is due to the
presence of an alarm in at least one of the other units connected to the LAN network.
5.4. SHARED USER TERMINAL
The shared user terminal (address 32) is managed by the application as follows:
•
Usually, it displays the information regarding the unit selected by the user by pressing [ESC] and [ALARM] simultaneously. Whenever this is
done the terminal switches onto the upper unit address.
•
In case of maintenance alarm or signal on any of the units connected to the LAN network, the user terminal automatically switches onto the
alarm/maintenance unit, in order to allow proper signalling.
Physically, the shared terminal may be connected to any of the network boards; moreover, it may be connected both on the unit (panel terminal) or in remote
position (wall terminal).
5.4.1.
Connecting the remote keyboard
Usually, just the on-board keyboard is used, directly connected to the J10 connector.
It is possible to connect a remote keyboard to the unit and it is possible to choose from different configurations.
