Cross-Zoning
Note
Cross-Zoning is not recom-
mended for exit/entry zones.
Each zone has the ability to
individually protect the
intended area. (e.g. motion
detector patterns overlap).
Cross-Zone (Alarm Verify) refers to two different Group 10-20 sensors that must be tripped
within four minutes of each other to report an alarm to the central station. The diagram in the fig-
ure below shows the path of a person walking from the kitchen to the living room. When the per-
son 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 four minutes, an
alarm report will be sent to the central station.
