Disabling and enabling logic groups
A group is a logic device that is created during system programming. Your system configuration may include
AND, Matrix, Service, Zone, or Instruction Text logic groups.
Logic groups are required in order to execute certain system functions, but have no physical relationship to the
system. For example, smoke detectors can be assigned to the same Zone group even though they are not
attached to the same wire run.
Disabling a logic group isolates it from the system. While the group is disabled, the control unit is prevented from
processing status change signals from every device in the group until the device is enabled. For example in a
Zone group, the control unit does not activate an alarm event when you activate a disabled detector, but it will
after the detector is enabled.
Notes
• The control unit keeps track of how many times you disable a logic group without enabling it. You must enable
a logic group the same number of times you disable it in order to return the group to its original condition. The
Status Disabled report provides a counter that shows the number of times the device was manually disabled.
• If you disabled a Zone logic group by disabling all of the devices in the zone, enabling the zone enables all of
the devices in the zone.
• Only users with fire privilege 3 can access this function.
To disable a logic group:
1. Sign in with fire privilege 3, and then tap Project Tree on the Action bar.
2. Expand the project tree by tapping the expand button , and then locate the target group.
3. Tap the group, and then tap Disable on the Command bar.
To enable a logic group:
1. Sign in with fire privilege 3, and then tap Project Tree on the Action bar.
2. Expand the project tree by tapping the expand button , and then locate the target group,
3. Tap the group, and then tap Enable on the Command bar. You must enable the device the same number of
times that you disabled it. If necessary, view the Status Disabled report to see the manual disable counter
(Action Bar > System Info > Status Disabled).
Disabling and enabling time controls
Time Controls are logic devices that are created during system programming. They are configured to set up
automatic starting and stopping of system events based on time and date. The controls run in the background and
do not require any operator action. In the event you need to disable a control, you can do so from the control unit.
Note: Only users with fire privilege 3 can access this function.
To disable a time control:
1. Sign in with fire privilege 3, and then tap Project Tree on the Action bar.
2. Expand the project tree by tapping the expand button , and then locate the target time control.
3. Tap the time control, and then tap Disable on the Command bar.
