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 (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. The diagram 
in Figure 14 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.

* This type is not certified as a primary protection circuit for UL-listed systems and is for supplementary use only.
§ This type is required for UL-listed residential fire alarm applications.
‡ This type has not been investigated by UL.
# See “Cross Zoning” section on page 72 
Delays:
I = Instant Delay (no delay, immediate alarm)
S = Standard Delay (alarm sounds after programmed entry delay time)
F = Follower Delay (alarm sounds immediately if entry/exit delay is not active, otherwise alarm sounds after programmed 
entry delay time)
