Equation Entry
D.4 Equation Entry
The equations must be entered using the VeriFire™ Tools Program Utility. All are subject to the
maximum number of arguments possible in a logic instruction as discussed above (Item Number 9
on page 106).
D.4.1 Logic Functions
The "AND" Operator
Requires that each argument be in alarm.
Example: AND(Z02,Z05,Z09)
All three arguments in the equation must be in alarm for the output point to be activated
The "OR" Operator
Requires that any argument be in alarm
Example: OR(Z02,Z05,Z09)
If any one of the three arguments in the equation is in alarm the output point will be activated.
The "NOT" Operator
Inverts the state of the argument (activated to deactivated OR deactivated to activated).
Example: NOT(Z02)
The output point will remain activated until the argument goes into alarm.
If the argument goes into alarm the output point will deactivate.
The "ONLY1" Operator
Requires that only one argument be in alarm.
Example: ONLY1(Z02,Z05,Z09)
If only one of the arguments is in alarm the output point will be activated.
The "ANY2" Operator
Requires that two or more arguments be in alarm.
Example: ANY2(Z02,Z05,Z09)
If any two or more of the arguments are in alarm the output point will be activated.
The "ANY3" Operator
Requires that three or more arguments be in alarm.
Example: ANY3(Z02,Z05,Z07,Z09)
If any three or more of the arguments are in alarm the output point will be activated.
The "XZONE" Operator
Requires that any combination of two or more input devices programmed to a zone be in alarm.
Example: XZONE(Z02)
If any combination of two or more initiating devices that have been programmed (CBE) to this
software zone comes into alarm, then this output point will be activated.
The "RANGE" Operator
Each argument within the range must conform to the requirements of the governing operator. The
range limit is 20 consecutive arguments.
