Addressable smoke detectors?

[syzygy]

Given the realm of what you're looking at monitoring and interfacing, I'd start looking at a panel like a Honeywell Vista and then if you want to put other functionality on it, deal with that independently.....and with multiple tenant items, you're looking at a commercial burg/fire panel combo and that leaves out the HAI and Elk panels to start off with.

 
Thanks, I'll take a look at that panel...

You're in the realm of a Vista 32FB or a V-128FB to start off with because of the commercial nature of the properties. Anything less than a commercial rated fire panel would be opening yourself up.

I'm still looking into it but in my area it looks like you don't get into commercial rated fire panels until you're 6 units and up...

I would speak to your local fire marshal and insurer before assuming. Keep in mind, the overall cost of the panel is insignificant, the only recurring would be the primary and backup comms.
 
Once you move into a multi-tenant occupancy is usually the deciding factor. In my area it's a 3 unit building/house.
