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, the 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 affect 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.Arming any 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.
The following chart summarizes how the common lobby partition will operate:
