The main difference between a forward-activated zone and a reverse-activated
zone is as follows:
A forward-activated zone has a Control-By-Event list of devices or higher
numbered zones that it will activate when it (the zone) goes into alarm. It enters
the alarm condition when an initiating device or lower numbered forward-
activated zone (FZON) that is mapped to it goes into alarm.
A reverse-activated zone has a Control-By-Event equation that must be
evaluated. If this equation becomes true the reverse-activated zone (RZON) will
go into alarm. The equation consists of operands such as devices or zones and
operators such as the OR, AND, NOT, XZONE, DEL, TIM and SDEL functions.
In Full System Programming a boundary must be set up between forward-
activated zones and reverse-activated zones. Every zone above this boundary
will be an RZON and every zone below this boundary will be an FZON. The
AM2020/AFP1010 has 240 software zones. For typical installations Notifier
recommends setting the boundary at Zone 200. Where Zone 200 would be the
highest number forward-activated zone and Zone 201 would be the lowest
number reverse-activated zone. Depending on your specific application this
boundary may need to be moved higher or lower.
Forward Activated Zones
A forward activated zone (FZON) is a zone that may be activated by any initiating
device (detector, monitor module, XPM point, or pull station) or by a lower
number FZON. In addition, once activated an FZON will execute it's Control-By-
Event (CBE) list which can only consist of a number of things to activate.
Example: Let's assume that Zone 10 and Zone 11 are both forward activated zones. Zone
10 is activated by an addressable pull station on the first floor. Zone 10's CBE list could
consist of the following:
(Z11 Z220 L1M80 L3M62 L10M33)
The above CBE is nothing more than a list of things to do. When Zone 10 goes into alarm
it will activate: Zone 11 (a higher number FZON), Zone 220 (an RZON), and L1M80,
L3M62, and L10M33 (these devices must be output type devices such as Control Modules,
XPC, or XPR points). Remember, by definition a FZON's Control-By-Event list is only a list
of things to do. It cannot contain any equations such as AND, OR, NOT, XZONE etc..
As in the example above, Zone 10 may be mapped to activate Zone 11. But,
Zone 11
cannot be programmed to activate Zone 10. Since Zone 10 is of lower
numerical value than Zone 11, Zone 11 cannot go back and activate it.
Reverse Activated Zones
A reverse activated zone (RZON) is a zone that may be activated by any initiating
device, forward activated zone, and also by it's own CBE equation (including
lower number RZON). Unlike forward activated zones, RZONs have a Control-
By-Event equation. The AM2020/AFP1010 continually processes each RZONs'
programmed equation. If the equation becomes true, the RZON will activate. For
examples of reverse-activated zone Control-By-Event equations, see specific
functions such as the OR, AND, NOT, XZONE, DEL, TIM or SDEL functions.
