Accessing Other Partitions (cont’d)
Common Lobby Operation
When an installation consists of a partition that is shared by users of other
partitions in a building, that shared partition may be assigned as a “common
lobby” partition for the system. An example of this might be in a medical
building where there are two doctors and a common entrance area.
This option employs logic for automatic arming and disarming of the common
lobby. Partitions may be set to affect and/or attempt to arm the common
lobby. This will affect the way the lobby will react when arming or disarming
activity occurs in another partition.
Partitions that affect the lobby will cause the following to occur:
a. When the first partition that affects the lobby is disarmed, the lobby will
also be disarmed.
b. The common lobby cannot be armed unless every partition selected to
affects the lobby is armed.
c. Arming the last partition that affects the lobby will not automatically
attempt to arm the lobby.
Partitions set to arm the lobby will cause the following to occur:
a. When the first partition that affects the lobby is disarmed, the lobby will
also be disarmed.
b. The common lobby cannot be armed unless every partition selected to
affects the lobby is armed.
c. Arming the last partition programmed to arm the lobby will
automatically attempt to arm the lobby. If any faults exist in the lobby
partition, or another partition that affects the lobby is disarmed, the
lobby cannot be armed, and the message “UNABLE TO ARM LOBBY
PARTITION” will be displayed.
