Input-to-Output Circuit Mapping and Cross-Zone Operation
A.1.3 Complex Examples of Cross Zoning and I/O Mapping for
Release Circuits
Following are some complex examples of cross-zoning for more demanding applications that are
possible with this fire panel. Input zone entries in a single cross-zone group are effectively AND'ed
together while the cross-zone groups are effectively OR'ed together. For the purpose of describing
this, the following language is used:
Example 5: Release Circuit 1 activates if either Input Zone 1 or 2 are active in addition to Input
Zone 3 being active.
•
R1 = (Z1 AND Z3) OR (Z2 AND Z3)
•
Set Zones 1 and 3 to YES in Cross Zoning Group 1 for RELEASE 1 in the CROSS INPUT
ZONES menus.
•
Set Zones 2 and 3 to YES in Cross Zoning Group 2 for RELEASE 1 in the CROSS INPUT
ZONES menus.
•
Set all other zones to NO in Cross Zoning Groups 1, 2 and 3 for RELEASE 1 in the CROSS
INPUT ZONES menus.
Example 6: Release Circuit 1 activates if Input Zones 1 and 2 and 3 are all active.
•
R1 = Z1 AND Z2 AND Z3
•
Set Zones 1, 2 and 3 to YES in Cross Zoning Group 1 for RELEASE 1 in the CROSS INPUT
ZONES menus.
•
Set all other zones to NO in Cross Zoning Groups 1, 2 and 3 for RELEASE 1 in the CROSS
INPUT ZONES menus.
Example 7: Release Circuit 1 activates if Input Zones 1 and 2 and 3 are all active. Release Circuit
2 activates if Input Zones 2 and 3 and 4 are all active.
•
R1 = Z1 AND Z2 AND Z3
•
R2 = Z2 AND Z3 AND Z4
•
Set Zones 1, 2 and 3 to YES in Cross Zoning Group 1 for RELEASE 1 in the CROSS INPUT
ZONES menus.
•
Set Zones 2, 3 and 4 to YES in Cross Zoning Group 1 for RELEASE 2 in the CROSS INPUT
ZONES menus.
•
Set all other zones to NO in Cross Zoning Groups 1, 2 and 3 for RELEASE 1 in the CROSS
INPUT ZONES menus.
•
Set all other zones to NO in Cross Zoning Groups 1, 2 and 3 for RELEASE 2 in the CROSS
INPUT ZONES menus.
Example 8: Release Circuit 1 activates if Input Zone 1 activates followed in time by Input Zone 2
activating.
•
This kind of sequential reaction is not possible at this time.
