Alarm system with logic on zones

Hi, in the process of setting up a HMO (house of mulitple occupancy). I would like to install an alarm if cost is not too much. However I will need an alarm with some flexability in zones and also logic to set whole house if all zones are set. The house is going to be split into 6 units with a communal lounge, hall stairway and kitchen diner. I would like a system where each person has the ability to set their living area (unit) onto a communal panel (with there own pin number obviously), and also if all 6 units are armed the last one to be armed should set the communal area to active. Is there an alarm available that offers this? It will be installed by myself.

Thanks

This is one panel that will do as you ask, might be a steep learning curve though
