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.

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