James is pointing out that your connecting to a relay which unless wired correctly will do nothing
Assuming the relay is triggered on alarm the no can stay in the bell trigger , but the c (common needs to connect to negative or minus or -ve ) that way when the alarm triggers it will connect the bell trigger to the negative it requires to ring it
Strobe I am not sure , the other outputs are programmable perhaps and you need to look at menus what they can do
