ABB GM/A 8.1 i’ve some questions.

[Hennessy]

One GM/A 8.1 comes with 8 entries and can hold two additional modules inside of its housing. This gives you already 16 entries.

Separate modules with 4 entries each can be bought with or without a housing.

Hi.
i’m thinking to replace my alarm panel with a gm/a 8.1 but i’ve some question.

I’ve 40 zones, so i need 9 auxiliary 4 fold input modules. Is there space into the panel box, to fit so much aux input modules?
if not, is there a way to buy a spare empty box?

As i can understand, the gma has a pstn line for voice calls. What about a gsm module? Cannot find it anywhere.

Thanks.
