Standard Signal Processing
Standard signal processing is recommended for high speed suppression systems only. To allow for high speed
operation, the standard processing mode does not incorporate the arc rejection programming. This mode should
only be used in a controlled, indoor environment.
IR Detector Options
The IR detector in the UVIR X5200 can be programmed for; “TDSA enabled” or both “TDSA and Quick Fire
enabled” (either initiates fire alarm).
Time Domain Signal Analysis (TDSA)
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 UVIR X5200 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.
Quick Fire (High Speed)
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.
