There will be 2 elevators. A public elevator which will serve floors basement (key access), floor 1 & 1R (key access), and floor 2. This elevator will allow access to the hall that would lead to the garage which will require a key to select. This is to protect the resources within the building.
The second elevator will be in the residence. This elevator will serve floor 2, and 3 and the roof (key access) which is where the elevator room for this elevator will be located. On the roof of the elevator, there will be an Over The Air antenna for public stations.
Unfortunately, elevators are still using obsolete RJ11 connections for their emergency call box. Ideally, they would use an RJ45 and SIP Programming, or cellular to connect to elevator services. By using RJ11, there will have to be a connection to Analog Telephone Adapters and connect to the home network. This sounds like a risky venture as if the power goes out, so does the network. However, the building will run on battery banks, and solar panels to refill the batteries. With conservative use, the batteries should provide electricity for a very long time.
