CBE “Null”:equation
You can also not program any equation for a device.
In this case:
- If the device in question is an input sensor or module, the control unit will activate only all general visual and
sound indications (Alarm LED on the front panel, General Alarm RELAY, BUZZER and possible output modules
programmed through TYPE ID software for general signallings).
- If the device in question is an output module, this output will never be activated unless it is programmed
through TYPE ID software for general signallings.
N. B.: for output modules, the control unit does not allow to program an equation if the module has a
TYPE ID for general signallings.
Operators used in the control by event equation:
OR
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:
(G9 G15 G23)
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.
AND
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.
NOT
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.
