Operators Used In The Control By Event Equation - Honeywell NOTIFIER AM-8200 Programming Manual

Operators used in the control by event equation:

is the operator which requires AT LEAST ONE operator to be ACTIVE.
Example: the output module equation is: OR (G9 G15 G23) or the OR operator can be omitted by entering:
If ANY of the three operands in this equation (G9 G15 G23) is in alarm; the output module will be activated, that
is:
- IF the software group 9 is in alarm, or
- IF the software group 15 is in alarm, or
- IF the software group 23 is in alarm
- THEN this output module will be activated.
is the operator which requires EACH operand to be ACTIVE.
Example: the output module equation is: AND (G9 G15 G23).
Only if ALL THREE operands in this equation are in alarm, the output module will be activated, that is
- IF the software group 9 is in alarm, or
- IF the software group 15 is in alarm, or
- IF the software group 23 is in alarm
- THEN this output module will be activated.
is the operator which DENIES the operand or the series of operands in brackets, which follow it.
Example: the equation of an output module is: NOT (G23).
The output module will remain activated until the operand (G23) IS alarmed, that is:
- If the software group 23 is in alarm
- THEN this output module will be deactivated.
N.B.
It is not allowed to write a CBE for a direct group, if the operands contained inside the round brackets
are some groups having an index lower than the group for which the CBE must be associated as in the
following example:
