G.1 Equations
Logic Equations can define complex relationships between input and output devices.
The NCA-2 supports up to 1000 Logic Equations, each designated with a Logic Zone number of ZL1 through ZL1000.
1. Equations will always begin with a logic function. The function set is listed below.
2. Equations will be a maximum of 80 characters long, including parentheses and commas.
3. Logic Equations can have a maximum of 10 logic functions unless a time delay function is used: a time delay function must be the
only function in its equation.
4. Equations are evaluated after all other devices have been evaluated.
5. One logic equation can be used as an argument in another logic equation, only if the equation used has previously been evaluated;
that is, only zones with a lower number than the zone currently being edited can be used as arguments.
6. A logic function can have a maximum of 20 arguments (inclusive start and stop address).
7. Maximum for the delay timer is 23 hours, 59 minutes, 59 seconds (23:59:59).
8. Mass Notification enabled systems: Logic zones must be written conditionally to ensure proper event suppression. Refer to the
Mass Notification manual for additional information.
Equations are entered using Point Programming for logic zones. Refer to these sections in this manual for instruction. The panel will
check for errors after the user has entered the complete equation. Possible errors are too many or two few parentheses, too many or two
few arguments inside the parentheses, unknown function and unknown device type.
Equations are made up of two basic components: functions (either logic or time delay) and arguments.
G.1.1 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.
(Nxxx)LxxD1 - (Nxxx)LxxD159
(Nxxx)LxxM1 - (Nxxx)LxxM159
(Nxxx)Z0 - (Nxxx)Z999*
(Nxxx)ZF0 - ZF7, ZF9 - ZF22, ZF36 - ZF40 special zones
(Nxxx)ZL1 - (Nxxx)ZL1000
(Nxxx)A1 - A32
(Nxxx)A1G1 - A32G16
xx = loop number (01 through 10)
(Nxxx) = Node number, necessary for CCBE programming. The node number identifies what node the
panel will watch for a particular zone activation.
G.1.2 Logic Equations
Logic Functions
• The "AND" Operator
Requires that each argument be active.
Example: AND(N01Z02,N01Z05,N01L2D12)
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(N01Z02,N02Z05,N01L2D12)
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(N01Z02)
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(N01Z02,N02Z05,N01Z09)
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.
