19 Arms Lobby (must be programmed by
partition)
Setting this field to 1 for a specific partition causes that
partition to affect the operation of the common lobby as
follows:
a. The common lobby cannot be armed unless every
partition selected to affect the lobby is armed.
b. Arming a partition that is programmed to arm the
lobby causes the system to automatically attempt
to arm the lobby. If any faults exist in the lobby
partition, or if another partition that affects the
lobby is disarmed, the lobby cannot be armed, and
the message "UNABLE TO ARM LOBBY
PARTITION" is displayed.
You cannot select a partition to "arm" the lobby
unless it has first been selected to "affect" the
lobby. Do not enable field 1

Example
Here is an example of how the lobby would react in a
typical setup.
OFFICE 1 OFFICE 2
MAIN ENTRANCE
COMMON LOBBY
V128BP-001-V0
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.
NOTE: In the tables below, the notations in
parentheses ( ) 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, because 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 to leave the building.
