There will be 2 elevators. A “common” elevator which will serve the basement, floor 1, floor 2, and roof (with key access). The second elevator will be in the residence and will serve floor 2, floor 3, and roof. Due to legal and safety issues, both elevators must have their own telephone line for the help call button. Both lines will connect to a dual port ATA (Analog Telephone Adapter), and provide a telephone connection to the elevator service company. The elevator room will be on the roof, and the roof of the room will host the television antenna.
