DESCRIPTION
The Fireye 95DSS3 InSight II is a family of versatile fully microprocessor based, integrated flame
scanners. The 95DSS3 holds multiple worldwide safety agency approvals (see Model Listings for
full details).
The InSight II scanners utilize advanced techniques for discrimination and integrate the flame detec-
tion, amplification, safety determination and flame switch functions into a single detection head. No
separate amplifier or flame switch module is therefore required to interface with the main burner
management system.
InSight II incorporates the superior detection and discrimination elements of the popular InSight
product with additional enhanced capability, features and benefits.
The scanner measures 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
can be either manually or automatically selected.
InSight II is a dual cell scanner utilizing UV and IR detector and various levels of housing type
including FM Class I Div 2 and ATEX ExdIIC (see Model Listing for full description of options).
Standard features include two independently adjustable Flame Relays that can be selected to operate
from the UV sensor, the IR sensor, or both sensors, 21 choices of modulation frequency, adjustable
sensor gain, adjustable flame relay ON/OFF thresholds, two 4-20 mA analog signal strength outputs
(one for FR1 and one for FR2), Fault Relay, four selectable programmable files (e.g. for different
fuels or firing rates), and Auto Config capability with manual override. Remote communication
capability is available via optional “Fireye Explorer” PC software (CU-109).
Ordered separately, a blank cover, or two different operator interfaces are available for the standard
(non-CEX) InSight II scanners enabling the user to view and change the operating parameters and
setpoints.
Model 95DISP-1 and 95DISP-1-SS are two-line by sixteen-character alpha-numeric VFD Displays
with five-pushbutton keypads. The 95DISP-1 is installed by the user onto the end of the scanners.
The 95DISP-1-SS is factory installed into the 95DSS3-1CEXSS and 95DSS3-1CEX-2 scanners.
Model 95WIDISP-2 is an Infrared Transmitter, installed by the user onto the end of the scanner
instead of a display. The 95WIDISP-2 transmitter provides wireless communications to a model
95WIHH-2 hand-held remote communications tool.
