Control-By-Event Programming
4.1 Control-By-Event Programming
Introduction
Control-By-Event (CBE) Programming is used to provide a variety of responses based on various
combinations of events (initiating conditions). The Control-By-Event Programming controls the interaction
between the alarm initiating devices, the internal software zones, and the alarm notification appliances
associated with an AM2020/AFP1010.
NOTE
A software zone is not a physical zone, but rather a software grouping in control panel memory.
Software Zones
The AM2020/AFP1010 contains 240 software zones to be used in CBE programming. These software zones
are broken into two types, Forward-Activating Zones (FZON) and Reverse-Activating Zones (RZON). These
forward and reverse zones must be grouped separately in the system's programming, with the forward group
always preceding by lower zone number the reverse group. This is accomplished by setting the Zone Boundary
(see Section 1.1.5, Zone Boundary , for more information on setting the zone boundary). Once the boundary is
set, all software zone numbers above the Zone Boundary are RZONs and all software zones below and including
the Zone Boundary are FZONs.
Forward-Activating Zones
FZONs are used to activate addressable output devices and/or other software zones. The software zones that
can be activated, however, must have a higher zone number than the FZON being utilized.
Reverse Activating Zones
RZONs are activated from addressable input devices and/or other software zones. The software zones that can
be used to activate a reverse zone must have a lower zone number than the RZON being activated.
Lists and Equations
Control-By-Event Programming can be accomplished in two ways, via the List and the Equation. Lists are
used for addressable initiating devices (detectors and monitor modules) and forward activating zones, where as,
Equations are used for addressable output devices (control modules) and reverse activating zones.
When an addressable initiating device or forward-activating zone is programmed with a List, the AM2020/AFP1010
activates all the items, called Operands , in the list when activation of the device or zone occurs. The operands
listed for an addressable initiating device can be notification modules and/or software zones (forward or reverse
activating). For a forward activating zone, the operands can be forward zones that are higher than its address,
reverse activating zones and/or addressable control modules.
Example:
A photoelectric detector has a List of (L1M1 L2M2), where L1M1 and L2M2 are control modules. When the
detector is in alarm, all the items in the Control-By-Event List are enabled so both control modules are
activated.
