LED states meaning:
• OFF – normal
• Solid - degraded
• Blinking - standalone
Naturally, the LED will not accurately indicate the condition (for example degraded vs.
standalone) of a node that is not in communication with the node the LED is located on.
Node Grouping
Node grouping is a way of isolating nodes from each other. Nodes that belong to one
group are isolated from nodes that belong to another group. Alarms and troubles that
occur in one group are not annunciated on the nodes of another group.
The Job Tree Node Grouping view allows user to view/create/delete node groups and make
node a member of one or more groups. Nodes that belong to one Group will be isolated
from nodes that belong to another group. This means that alarms and troubles that occur
within one group are not annunciated on the nodes of another group. For example, in the
case of a two tower complex, the DGP nodes of the North Tower would be placed in the
North group and the DGP nodes of the South Tower would be placed in South group. If
there is a CACF Node in a common area (e.g. a lobby) it could be placed in both groups.
Alarms, Fire Dill activation, etc. initiated in the North Tower would not be transmitted to the
South Tower and vice versa. The CACF, because it is a member of both groups, will receive
and annunciate events from both towers.
In a combined fire and Mass Notification System (M.N.S.) installation Node Grouping can be
used to separate the M.N.S. nodes of from those nodes supporting fire. Create two Groups,
Fire and M.N.S. Place the nodes to which the fire devices are connected in the Fire group.
Place those nodes that support M.N.S. in the M.N.S. group. Priority can be given to either
MNS or Fire depending on the results of the client’s risk analysis. For example, if it was
determined that M.N.S. has priority over fire, then all M.N.S. controls must be given a higher
priority than fire inputs. See Input Zones and Display Adders for details on setting priorities.
Creating node groups and adding nodes to groups
1. Create two nodes, and give them appropriate tags, for example Fire Panel and
MNS Panel.
2. In the left pane, select Node Grouping.
3. Click Insert - Add Group.
4. Type a name for the group, for example Fire Group, and then click OK.
