Using this dialog the user can compose an equation to be applied to a local, dummy input
zone. The input zone is then correlated, using regular IO corrs, to the output which is
ultimately the object of the equation. This is done by specifying any number of local and
remote inputs zones, local input circuits, timers and intervals (operands) and boolean
expressions (operators).
When the result of the equation, evaluating the TRUE/FALSE state of all inputs, is TRUE the
associated output will be energized. The equation overrides any other Input/Output
correlations.
WARNING: Applying an equation directly to an output bypasses all of the associated inputs
and outputs. That is - coded inputs are not processed, etc. Use of a dummy input zone as
the intermediary is the preferred method.
The operands recognized by the equation builder are
• AND
• OR
• NOT
• EQU
• ANY x OF( inputs )
Examples:
Example 1: Use the status of two input detectors to turn on a relay
If we have two smoke detectors:
01-00-L2-SM-001 (in the lobby)
01-00-L2-SM-002 (in the elevator machine room)
the following equation will turn a relay on when the detector in the lobby is in alarm, but
the one in the machine room is not:
01-00-L2-SM-001 AND NOT 01-00-L2-SM-002
Example 2: Use the ANY x OF ( inputs ) operand to turn on an output
Release halon in a semiconductor clean room only if 3 of the 11 verified alarms in the area
are active.
ANY 3 OF ( 01-00-L2-SM-001 , 01-00-L2-SM-002 , 01-00-L2-SM-003 , 01-00-L2-SM-004 ,
