How to link smoke detectors?

Hi,

basic question on how to link z-wave smoke detectors (Heiman HS1SA-Z).
What I want to achieve is that, if there is smoke detected in a room, ALL alarms ring.
Can I use associations for this? If so, I guess I need the notification command class, that can have 5 members with the HS1SA-Z.

do I have to link every detector wich every other detector? so telling node 5 to notify 6, 13, and 14 (my 4 smoke detectors), telling node 6 to notify 5, 13, 14 and so on?

thanks a lot in advance.
