INDEPENDENT BUILDING ACCESS:
A two building, three 2001 Lobby Unit NSL configuration. Each building's 2001 Lobby Unit (only one is shown per
building, but there could actually be more, such as for multi-entrances) uses one Audio Line. Each 2008M NSL Unit
(and any 2008/16 NSL Expanders) connects to two Audio Lines (each has capability for 5 Audio Lines); one Audio Line
for its own Building's Lobby Unit, and one for the Parking Garage Lobby Unit. This allows The Lobby Unit(s) in each
building to call Residents in that building independently of each other, and the Garage Lobby Unit can call Residents
in either building (although while the Garage Lobby Unit is calling a resident in a building, that building's own Lobby
Unit(s) are locked out).
