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 using the FIRE DET Qualifier, the statement holds true for ½
second. This allows the output to re-execute after a signal silence.
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.

Figure 3-19. An Example Where Fire Detect Re-executes
Example: The condition of 03-01 is FIRE DET. The appropriate notification
appliances are silenced from the FACP. After the notification
appliances are silenced the condition of 03-02 is FIRE DET. The
notification appliances now resound for the FIRE DET condition of
03-02.
