CBE: Zones and Equations Equations
E.2 Equations
Logic and Trouble Equations can define complex relationships between input and output devices.
The FACP supports up to 1000 Logic Equations, each designated with a Logic Zone number of
ZL1 through ZL1000. It also supports up to ten Trouble Equations, each designated with a Trouble
Zone number of ZT001 through ZT100. Once created, these equations can be included in
input/output zone mapping.
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 and Trouble 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, or one trouble
equation can be used in another trouble 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).
Equations are entered using Point Programming for logic or trouble 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.
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 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
LxxD1 - LxxD159 detectors loop xx (159 per loop)
LxxM1 - LxxM159 modules loop xx (159 per loop)
P(1-12).(1-8) panel circuit modules (96)
(Nxxx)Z0 - (Nxxx)Z999* general zones (1000)
ZF1, ZF2, ZF3, ZF4, ZF5, ZF9 special zones (6)
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 panel will watch for a particular zone activation.
