Hochiki Loop explorer

Hi
I am using Hochiki Ul listed products. I am a problem with loop explorer commissioning. Suppose i have 4 loop panel and every loop there are 100 devices. For each loop i used SOM-A for horn/sounder. So i have 4 different 24v connection from a external power supply for 4 loop. I want if any detector from any loop detects fire then all sounder will active. How can i commissioning in loop explorer for this?
Also same issue if use NAC1, NAC2,NAC3,NAC4?

where i can buy hochiki loop explorer software…?
