Configuration
Enter the tagname for the detector, a miscellaneous description and then adjust the IR Settings.
Processing Mode
The IR X9800 features signal processing options.
These options determine the type of logic that the detector will use for processing fire signals to customize the
IR X9800 to the application.
Two signal processing options are available for the IR X9800: “TDSA” and “TDSA & Quickfire”.
TDSA enabled
The TDSA signal processing technique analyzes the input signal in real time, requiring the IR signal to flicker
randomly in order to recognize it as a fire condition.
Using TDSA signal processing, the X9800 ignores regularly chopped blackbody sources (occurring in areas
where moving conveyors and hot objects in proximity to one another result in a regularly chopped IR signal),
because it looks for a less uniform signal.
However, in the presence of a regularly chopped signal, the unit is more susceptible to false alarms due to
sporadic IR that functions as a trigger when occurring in conjunction with the regularly chopped signal.
TDSA & Quick Fire enabled
Either initiates fire alarm.
The Quick Fire (High Speed) feature can be used in conjunction with the TDSA signal processing method.
This method overrides TDSA requirements in the event of an intense signal. When Quick Fire is activated, the
detector is capable of responding to an intense fire signal in less than 30 milliseconds (0.030 seconds).
Using the Quick Fire feature in conjunction with TDSA signal processing allows the detector to provide a high
speed response to a large, non-flickering fire (such as in high pressure gas applications) while maintaining an
ability to respond to smaller fires.
