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.
Table 5 Cross Zoning Types
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).
Table 6 Devices Mapped to Releasing Zones
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).
Type Activates when...
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.
