Disabling groups
A group is an object created during system programming.
Groups are required in order to execute certain system functions,
but groups bear 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 group isolates the group from the system just as if it
were a hardware component. Disabling a zone group disables
each of the devices in the group individually. Disabling other
groups only disables the group response.
There are several types of group:
• And group
• Check-in group
• Matrix group
• Service group
• Guard patrol group
• Zone group
• Instruction text group
When you disable a group, the 3-CPU1 lights the 3-LCD Disable
LED and places a Disabled Active event in the trouble queue.
Note: Before disabling a group, you need to know which devices
are included in the group. You should be able to get a list of
logical groups and their members from the company that
installed the system.
To disable a group:
1. Press the Command Menus button , then choose Disable.
2. Choose Group.
3. Choose the group type.
4. Select the group from the list.
5. If prompted, enter a valid user access level password.
