Managing Cross-Zone Associations
A cross-zone association requires the following for an alarm to be tripped:
• Two specific sensors are faulted
• The sensor are faulted in a particular order
• The sensors are faulted within a set time period
For example, you can require that a door be opened and that a motion sensor detect movement in
order for an alarm to be tripped. This can be useful way to avoid a pet inadvertently setting off a
motion sensor alarm.
If a Cross-Zone association needs to be modified, delete it (page 93) and create a new one.
Things to Know about cross-zone associations:
• Neither sensor in a cross-zone association will trip an alarm individually ever, in any situation.
• The associated zones will not trip an alarm if they are faulted in the wrong order.
• You cannot associate a single sensor in more than one cross-zone association.
Important: Do not use a Cross-Zone association for an Entry/Exit security zone. A Cross-Zone
association will override the Entry Delay for such exits.
