Yes, in my case i have 8 door contacts...and 8 sirens(which i can give external power, since the panel doesnt have enough power to feed).
So whenever any of the door contact opens, corresponding siren should ring.
Yes, i know that flex20 has only 7 outputs maximum possible. So 3 i have already done in the main panel.Its working fine.
But when it came to RIO with address 2, zones i a can monitor, but outputs, i can see any changes even after configuring them.
Also while Testing ON/OFF doesnt work for the RIO Outputs.
