Fireye 95DSS2-1CG Integrated Flame Scanner with Internal Flame Relay.
The FIREYE InSight Type 95IR, 95UV, and 95DS flame scanners are micro-processor based flame
scanners utilizing solid state infrared (IR) or ultraviolet (UV) or dual (IR and UV) sensors.
The FIREYE InSight Type 95 flame scanners incorporate an internal flame relay with adjustable
ON/OFF thresholds, thereby eliminating the need for a remote flame amplifier.
The InSight scanners incorporate elements of the FIREYE Type 45FS1 and 45UVFS1 Signature
ScannersTM as well as of the Type 45RM4 flame scanners to detect the presence or absence of a tar-
get flame in single or multi-burner applications.
The InSight scanners measure the amplitude of the modulations (the flame "flicker") that occur
within the targeted flame. During the scanner set-up procedure, the modulation frequency that yields
the best flame ON/OFF discrimination is selected. The appropriate modulation frequency and sensor
gain is either manually selected (S1 models), or automatically selected with manual override capa-
bility (S2 models).
The InSight 95IR, 95UV, and 95DS scanners are each available in two models differentiated by fea-
The Standard Model S1 has three choices of modulation frequency, adjustable sensor gain, adjust-
able flame relay ON/OFF thresholds, 4-20 mA analog signal strength output, fault relay, and two
selectable programmable files to store setpoints (for two different fuels or firing rates).
The Expanded Model S2 adds automatic programming (AutoTune) with manual override capability,
21 choices of flame flicker frequency, a total of four selectable programmable files to store setpoints,
plus adds remote communication capability via Fireye Windows 95/98/NT user software.
All FIREYE InSight scanner models are powered by 24 Vdc and contain electronic self-checking
(no mechanical shutter required). The scanners contain an eight character alpha-numeric LED display and
a four (4) push-button keypad to enable the user to view operating parameters and select setpoints.
CG models include a 10 ft. (3m) captive cable and gland. Non-CG models have a twelve-pin
electrical quick-disconnect. Fiber optic-mount versions of the InSight scanners are also available.
