That system is a Br1nks branded system. Which means that you would have to add keypads made for that particular system, and any added zones would have to be programmed, and that would need to be done with a special programmer, which Br1nks, keeps a pretty close eye on. I do believe it is an 8 zone panel, but like most, has the ability to be expanded with zone expander modules. Anyway, what it boils down to, is you would need to have a Br1nks/Br0adv1ew tech do the additional programming.
Sorry I couldn't be a little more help.
