An example of this might be in a medicalbuilding where there are two doctors and a common entrance area.This option employs logic for automatic arming and disarming of the commonlobby. Partitions may be set to affect and/or attempt to arm the commonlobby. This will affect the way the lobby will react when arming or disarmingactivity 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 willalso be disarmed.b. The common lobby cannot be armed unless every partition selected toaffect the lobby is armed.c. Arming the last partition that affects the lobby will not automaticallyattempt to arm the lobby.Partitions set to arm the lobby will cause the following to occur:a.

If any faults exist in the lobby partition, oranother partition that affects the lobby is disarmed, the lobby cannot bearmed, and the message “UNABLE TO ARM LOBBY PARTITION” willbe displayed.The following chart summarizes how the common lobby partition willoperate:Partition AffectsLobbyPartition ArmsLobbyDisarms WhenPartition DisarmsAttempts to ArmWhen PartitionArmsCan Be Armed ifOther PartitionsDisarmedNO NO NO NO YESYES NO YES NO NOYES YES YES YES NONO YES ---ENTRY NOT ALLOWED---
