Using Cross Zoning Options  Cross Zoning lets you program the control panel to 
activate a releasing zone after two initiating devices are tripped. (If not using Cross 
Zoning, set CROSS= to N.) Table 5 contains a summary of the types of cross zoning 
and the conditions for activating a releasing zone.

Note: Only the first non-special 
zone listed in the zone map is 

used to determine Cross=Z.

Cross Zoning Example Table 6 lists examples of devices mapped to releasing zones 
(ZR1 stands for Releasing Zone 1).

The following explanations apply to the examples listed in Table 6:

•

Cross=N An alarm from any detector activates the releasing circuit.

•

Cross=Y   An alarm from any two detectors activates the releasing circuit.

•

Cross=Z  Release requires the activation of two detectors mapped to different 
zones:  D101 and D102 cannot activate the releasing circuit because both detectors 
are mapped to Z01; D101 and D103 can activate the releasing circuit because they 
are mapped to different zones.

•

Cross=H   Release requires activation of heat detector D104 and one smoke 
detector (D101, D102, or D103).

Y

Two or more detectors, all mapped to one of the ten releasing zones (R0-R9), are 
tripped.

Z

Two or more detectors, mapped to two different software zones and one of the ten 
releasing zones (R0-R9), are tripped.

H

At least one smoke detector and at least one heat detector, all mapped to one of the 
ten releasing zones (R0-R9), are tripped.
