The Common Lobby feature employs logic for automatic arming and disarming of the common lobby. Two programming

fields determine the way the common lobby will react relative to the status of other partitions. They are: 1*18 Affects

Lobby and 1*19 Arms Lobby.

1*18 Affects 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. When the first partition that affects the lobby is disarmed, the lobby is automatically disarmed.

b. The common lobby cannot be armed unless every partition selected to affect the lobby is armed.

1*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*19 without enabling field 1*18.

The following chart sums up how the common lobby partition will operate.
