Circuit Mapping and Cross-Zoning

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:

R1

=

RELEASE 1

R2

=

RELEASE 2

Z1

=

INPUT ZONE 1

Z2

=

INPUT ZONE 2

Z3

=

INPUT ZONE 3

Z4

=

INPUT ZONE 4

Z5

=

INPUT ZONE 5

Z6

=

INPUT ZONE 6

OR

= any input zone may cause a release

AND

= all input zones must be active for a release

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.
