switch 8 according to Table 2.

Note: 

The siren can be supplied from the input N1 or N2. In case it is supplied from both inputs 

then N1 has priority. Depending on the connection you will choose and the setting of DIP 
switches 1 to 5 the corresponding pattern will sound. By connecting the siren to input N1 and 
configuring DIP switches 1 to 5 the pattern that will sound is shown in Table 5. By connecting 
the siren to input N2 and configuring DIP switches 1 to 5 the pattern that will sound is shown in 
Table 4. The difference in the patterns between N1 and N2 allows the device to be used both as 
a pre-alarm and alarm indication.

Test the operation of the device through the panel after the installation.
UID: In every device there is a double sticker with the UID (Unique Identifier) number. 
This number is unique for each device.
