Help adding additional sounder to network

[Adeotec]

I currently have a DFF1/VX2 system. I've installed a DFF3 and additional transducers but I am keeping the DFF1 and original transducer active.
The dip switches on the DFF1 and DFF3 are currently set to work with a VX2 system.

1) I'm unclear if I need to reset the DFF1/3 dip switches to a specific positions because two sounders will be active on the same network.
2) Is there an online manual which describes the steps needed to add the DFF3 sounder to the network? I assume I'm going to need to change the address for both the DFF1 and DFF3. I couldn't find a step by step instructions on how to do that.

Thank you for your help

Adeotec,
The default IP address are the same for the DFF1 & DFF3 so you will only need to change one sounder module. I suggest setting the dip switches on the DFF1 to 1-on, 2-on, 3-off and 4-on. The number two dip switch changes the IP address from 0 to 1.
