Disabling and enabling logic groups
A logic group is an object that is created in the VM-CU. 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 it from the system. While the card is disabled, the VM-1 logs the status change signals
but is prevented from processing the signals until the card is enabled. For example in a zone group, the control
panel does not activate an alarm event when you activate a disabled detector, but it will after the detector is
enabled.
The VM-1 keeps track of how many times you disable a group without enabling it. You must enable a group the
same number of times you disable it in order to return the group to its pre-disabled condition.
Note: If you disabled a zone group by disabling all of the devices in the zone, enabling the zone enables all of the
devices in the zone.
The logic groups are listed below.
• AND group: A collection of devices that are grouped in the database to provide a group response that is
separate from that of its member devices. An AND group activates when a specified number of devices
change to a specified state. The specified state can be alarm, supervisory, trouble, monitor, or not active
(NA). AND groups can be configured to signal an alarm, supervisory, trouble, or monitor condition upon
activation.
• Service group: A collection of devices that are grouped together in the database to provide a unique response
for testing purposes. When enabled, the Service group automatically disables the member device's normal
alarm response, and provides a common alternate test response.
• Zone group: A collection of input devices that are grouped in the database order to provide a unique response
separate from their individual device responses. Zone groups can be configured to go into alarm when any
member of the group goes active or when any device in the group goes into trouble.
• Instruction text group: A collection of devices that are grouped in the database to provide additional detailed
instructions or warnings when any device in the group changes to a qualified active state.
To disable a group:
1. Access the Main Menu, and then select Disable.
2. Select Group, and then select the group type.
