texecom oddysey 3, fault relay output?

i have wired 2 texecom odysseys 3's back and front with using sab and scb combo. i have wired them with 8 core. there is a single cable from the panel luckily 8 core. i have moved this to a junction box then ran the two 8 cores cables from the junction box to the sounders. i understand how to wire the 2 together apart from the fault output.

is it just a case of wiring the fault output in series from each sounder? thanks
