Seeking DIY System for My Tenants Apartment

["Tom" <TomBrook11232@xxxxxxxxx>]

Would anyone like to recommend a system for an upstairs apartment that
I'm renovating?

I would like:

- DIY wired system.    Walls and ceilings are presently stripped bare.


- Easy to operate.   Tenants will be using it, not me.   This is a
biggie.

- CSM capable.  Whether they use it or not will be up to them.

- Override/operate ability for me.

- Anything else I forgot/might be nice....?

Apartment Specs:

- Floor: 2 nd
- Rooms: 4 + Hallway, railroad layout, bathroom off hallway.
- Doors: 2:  1 in front room, 1 in hallway.  Both open to common
hallway (shared with other upstairs apartment.)
- Windows: 2 facing street, 2 facing backyard, 4 facing central
airshaft.

Thanks,
Tom
