Example
Here is an example of how the lobby would react in a typical setup.
MAIN ENTRANCE
OFFICE #1 OFFICE #2
COMMON LOBBY
User #1 has access to Office #1 and the Common Lobby.
User #2 has access to Office #2 and the Common Lobby.
Office #1 is set up to affect the Common Lobby, but not arm it.
Office #2 is set up to affect and arm the Common Lobby.
For the purpose of this example, the ( ) indicate the current status of the other
partition when the user takes action.
Sequence #1:
Office 1 Office 2 Lobby Action
User #1: Disarms (Armed) Disarms
User #2: (Disarmed) Disarms No Change
User #1: Arms (Disarmed) No change
User #2: (Armed) Arms Arms
Sequence #2:
Office 1 Office 2 Lobby Action
User #2: (Armed) Disarms Disarms
User #1: Disarms (Disarmed) (No change)
User #2: (Disarmed) Arms No Change
User #1: Arms (Armed) No Change
Notice that in sequence #1, since Office #2 was the last to arm, the lobby also
armed (Office #2 is programmed to affect
and arm the lobby). In sequence #2,
the lobby could not arm when Office #2 armed, because Office #1, which affects
the lobby, was still disarmed.
When Office #1 armed, the lobby still did not arm because Office #1 was not
programmed to arm the lobby. User #1 would have to arm the lobby manually.
Therefore, you would want to program a partition to affect
and arm the lobby, if
the users of that partition are expected to be the "last out" of the building.
