Equations CBE: Zones and Equations
Equations are made up of two basic components: functions (either logic or time delay) and
arguments.
E.2.1 Arguments
Arguments are discrete parts of a logic or time delay function used in a logic or trouble equation.
They can consist of another function, another equation, or any of the devices listed below.
E.2.2 Logic Equations
Logic Functions
• The “AND” Operator
Requires that each argument be active.
Example: AND(Z02,Z05,L2D12)
All three arguments in the equation must be active for
the logic zone to be activated.
• The “OR” Operator
Requires that any argument be active
Example: OR(Z02,Z05,L2D12)
If any one of the three arguments in the equation is active the logic zone will be activated.
•
The “NOT” Operator
Inverts the state of the argument (activated to deactivated OR deactivated to
activated).
Example: NOT(Z02)
The logic zone will remain activated until the argument activates.
If the
argument activates the logic zone will
deactivate.
• The “ONLY1” Operator
Requires that only one argument be active.
Example: ONLY1(Z02,Z05,Z09)
If only one of the arguments activates the logic zone will be
activated.
• The “ANYX” Operator
Requires that the amount of arguments specified by the
number preceding the arguments be
active.
Example: ANYX(2,Z02,Z05,Z09)
If any two or more of the arguments are in alarm the
output point will be activated.
The X amount may be a value from 1 through 9.
• The “XZONE” Operator
Requires that any combination of two or more input devices programmed to a zone be active.
LxxD1 - LxxD159 detectors loop xx (159 per loop)
LxxM1 - LxxM159 modules loop xx (159 per loop)
(Nxxx)Z0 - (Nxxx)Z999* general zones (1000)
ZF1 - ZF7, ZF9 - ZF19 special zones (18)
T0 - T510 system troubles (trouble equations only) (511)
(Nxxx)ZT001 - (Nxxx)ZT100 trouble zones (100)
(Nxxx)ZL1 - (Nxxx)ZL1000 logic zones (1000)
xx = loop number (01 through 10)
(Nxxx) = Node number, necessary for CCBE programming. The node number identifies what node the
p
anel will watch for a p
articular zone activation.
