74 Programming—IFC-1010/2020 Programming
Option 7 from the Alter Status menu allows the programmer to disable or
subsequently re-enable all appropriately mapped points (input devices and
zones) associated with a particular software zone. When a point is
disabled, it is no longer polled by the IFC-1010/2020.
When a zone is disabled using this feature, a trouble message is generated
for this zone. Then the entire CBE database is searched for all input
devices and zones, looking for this group zone to be the first zone in each
point’s individual CBE. A trouble message is generated for each point
(input device or zone) matching the above criteria as it is found and the
point will be disabled. During the search process, the user interface is
locked out.
The following example illustrates group disabling Zone 2.
Note: The programmer should never program a disabled point.
PRESS 1=DIS,2=CTL,3=DSEN,4=TIME,5=DIAG,6=WALK,7=GZON :7
ENTER ZXXX FOR GROUP ZONE CHANGE :Z2
DO YOU WANT THIS GROUP ZONE DISABLED? (Y=YES, N=NO) :Y
Example:
Point
Z1
Z2
Z3
L1D1
L1D2
L1D3
L1M1
L1M2
L1M3

As a result of disabling Z2 using the group
zone disable function, L1D2 and L1M2 are
automatically disabled as well.

Figure 71: Example
The first zone does not necessarily mean being the first operand in a CBE.
A zone can be located anywhere within the CBE. The following CBE
examples all have the same effect for group zone functions:
(Z1)
(Z1 L1M1)
(L1M1 Z1)
(L1M1 L1M2 Z1 Z2)
Z1 is the first zone found in each individual CBE.
