Appendix A: AM2020/AFP1010 Control-By-Event

A.1 Introduction
Control-By-Event (CBE) Programming is used to provide a variety of responses based on various combinations of events (initiating condi-
tions). 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/INA.
A.2 Lists and Equations
Control-By-Event Programming can be accomplished in two ways, via the List and the Equation. Lists are used for initiating devices (detec-
tors and monitor modules) and forward activating zones, whereas Equations are used for output devices (control modules) and reverse acti-
vating zones.
When an initiating device or forward-activating zone is programmed with a List, the AM2020/AFP1010 activates all the items, called Oper-
ands, in the list when activation of the device or zone occurs. The operands listed for an 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 notification 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.
The real power of the CBE Programming comes from the Equation, which is evaluated by the control panel to determine a variety of alarm
initiating conditions. The Equation provides the real decision-making ability through the use of an operator acting on a set of operands. The
operands for an output module can be initiating devices, software zones (forward or reverse-activating), or control modules assigned an
address lower than its own. For a reverse-activating zone, the operands can be initiating devices, forward zones, or reverse zones that are
lower than its address.
The format for an Equation is shown below, where the operators are OR, AND, NOT, XZONE, DEL, SDEL, and TIM; and the operands are
groupings of initiating devices and/or software zones, as well as information specific to the format of individual operators.
Operator(- - - - Operands - - - -)
Examples:
OR(Z9 Z15 Z23)
AND(L1D1 Z3 L1D35 L1D72)
NOT(Z23)
XZONE(Z23)
DEL(HH.MM.SS HH.MM.SS (L1M1))
SDEL(HH.MM.SS HH.MM.SS (Z1))
TIM(SU MO TU WE TR FR SA HH.MM HH.MM)
All of the operator formats above are explained in detail on the following pages.
A.2.1 Control-By-Event Programming Constraints
• There can only be one DEL or SDEL operator in a control-by-event equation, not both.
• If there is no duration time field in a DEL or SDEL, the equation will always be activated.
• The maximum value of DELAY TIME + DURATION TIME is 255:59:59.
• If either the day, month or year field is omitted, that field is assumed to be all allowable values of the field omitted. Example: 12--90 is
equivalent to any day in December 1990.
• The HH.MM field for START TIME and STOP TIME uses military time.
• The HH.MM field for STOP TIME must be greater than the START TIME.
• The maximum value of START TIME or STOP TIME is 24:00.

NOTE: A software zone is not a physical zone, but rather a software grouping in control panel memory.
