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 29 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.

Note: We do not recommend cross-zoning for exit/entry zones. Each zone can individually protect the intended area.
