Technical Manuals Online! - http://www.tech-man.com
When using the input condition qualifier FIRE DET (Fire Detect), a statement is
true when the point indicated in Field 4 is activated. Field 4 Choices for the
FIRE DET qualifier are:
•
System Card Points
•
Digital Pseudo Points
Note:
When the condition of 03-01 is FIRE DET, the input is true for ½ second and the
output is executed. If the condition of 03-02 becomes FIRE DET after 03-01,
the system re-executes the output. In other words, if the output executes from
the FIRE DET condition of 03-01, the output re-executes from the FIRE DET
condition of 03-02.
