Description

The 25SU3-2150 is used to detect the presence or absence of a flame in a single or multi-burner environment. It also maximizes burner discrimination with its ability to accurately differentiate the Flame ON and Flame OFF rates produced by the scanners.

The 25SU3-2150 has the capacity to receive pulse inputs from two flame scanners, “A” and “B,” either separately or in combination. In addition, it has two logic programs available, called “Scanner Option 1” and “Scanner Option 2.” Within these two scanner options, the user may select different operating parameters and select the scanner or scanners that will provide the pulse input for that option. Switching between “Scanner Option 1” and “Scanner Option 2” is accomplished by an external dry contact input to the amplifier. The dynamic range is 1900 pulses per second, which is consistent with the output range provided by Fireye scanners. The pulse rate output of each scanner is directly viewed by the user.
