Cross-zoning
Cross-zoning (two-trip) refers to two different group 18 sensors that must be
tripped within two minutes of each other to report an alarm to the central station.
Figure 2 shows the path of a person walking from the kitchen to the living room.
When the person is detected walking through the kitchen, the motion sensor in
the kitchen is tripped, sounding a local alarm. If motion is detected by the living
room motion sensor within two minutes, an alarm report will be sent to the central
station.
