3.5.4 Cross Input Zones
An application may require that two or more input zones become active at the same time before a
particular releasing output activates. This is referred to as cross-zoning. For example, an installer
may want four particular zones to become active at the same time before a releasing circuit is
activated. By using the Cross Input Zone feature, the programmer can designate the input zones
that must become active and the output circuits that will be affected.
The Cross Input Zone option allows the user to view and program the groups of input zones that
will be used to activate one of the releasing output circuits. Pressing 1 while viewing Programming
Screen #2 will display a screen similar to the following:
This screen allows the programmer to view the cross-zoned grouping for Release Circuit 1 or
Release Circuit 2. In the following example, Template 7 has been chosen as the FACP
Configuration [refer to "FACP CONFIG (Application Templates)" on page 50]. Pressing 1 for
Release 1 Groups will display the following screen:
The display indicates that Input Zone 1 is cross-zoned with Input Zone 2. Input Zone 3 is not cross-
zoned.
The user can alter the cross-zoning by pressing the number key corresponding to the Zone to be
reprogrammed. Screens similar to the following will be displayed:
