Common Area Logic
When an installation consists of one or more partitions shared by users of other partitions in
a building, those shared partitions may be assigned as the "common area" partitions for the
system (programme fields 1*11, 1*14, 1*17). An example of this might be in a medical
building where there are two doctor's offices and a common entrance area (see example that
follows explanation).
This option employs logic for automatic arming and disarming of the common area.
Programming fields affect the way the common area will react relative to the status of other
partitions. They are: 1*12, 1*15, 1*18 (Affects Common Area) and 1*13, 1*16, 1*19 (Arms
Area).
1*12, 1*15, 1*18 Affects Common Area
(must be programmed by partition)
Setting this option to 1 for a specific partition causes that partition to affect the operation of
the common area as follows:
a. When the first partition that affects the common area is disarmed, the common area will
also be disarmed.
b. The common area cannot be armed unless every partition selected to affect the common
area is armed.
c.
Arming the last partition that affects the common area will not automatically attempt to
arm the common area.
1*13, 1*16, 1*19 Arms Common Area
(must be programmed by partition)
Setting this option to 1 for a specific partition causes that partition to affect the operation of
the common area as follows:
a. When the first partition that affects the common area is disarmed, the common area will
also be disarmed.
b. The common area cannot be armed unless every partition selected to affect the common
area is armed.
c. Arming the last partition that is programmed to arm the common area will automatically
attempt to arm the common area. If any faults exist in the common area partition, or
another partition that affects the common area is disarmed, the common area cannot be
armed, and the message "UNABLE TO ARM LOBBY PARTITION" will be displayed.
You cannot select a partition to "arm" the common area unless it has first been
selected to "affect" the common area. Enable field 1*12, 1*15, 1*18 before enabling
field 1*13, 1*16, 1*19 respectively.
The following chart summarizes how the common area partition will operate if different
options are set for another partition in fields 1*18 and 1*19.
