INTEGRATED FLAME SCANNER
WITH TWO INTERNAL FLAME RELAYS
Type 95DSS3 II
The FIREYE InSight II Type 95DSS3 flame scanners are
micro-processor based flame scanners utilizing both
solid state infrared (IR) and ultraviolet (UV) sensors.
The FIREYE InSight II flame scanners incorporate two internal
flame relays with adjustable ON/OFF thresholds
and two 4-20 mA analog outputs, thereby eliminating
the need for a remote flame amplifier.
The FIREYE InSight II scanners are powered by 24 Vdc
and have electronic self checking. Model 95DSS3-1
has one 8-pin and one 12-pin electrical cable quick
disconnect. Models 95DSS3-1CEX and -1WICEX have
internal terminal blocks for cable connection. The
scanners have either an attached Keypad & VFD display,
or an infrared transmitter for a remote handheld
keypad / display.

WIRELESS HANDHELD

COMMISSIONING TOOL
WITH 95WIDISP-2 INFRARED TRANSMITTER
II
The 95WIHH-2 Wireless Handheld Commissioning Tool
is an intrinsically safe, wireless IrDA ready device designed
to be used with InSight II scanners. The device
can be used to remotely navigate the InSight II scanner’s
menu, set and review operating parameters,
and view error messages and alerts.
The device offers an IrDA automatic address discovery
feature that enables an end user to quickly
establish a communication link with the target scanner
without having prior knowledge of the scanner’s
address. The address discovery feature is particularly
useful in applications where multiple scanners are
deployed.
The 95WIDISP-2 transmitter provides wireless communications
to a model 95WIHH-2 hand-held remote
communications tool.
• Intrinsically Safe Device
• Wireless IrDA Ready
• Auto Scanner Detect Mode
• Communicate up to 5 feet

The FIREYE InSight II Type 95DSS3-1CEXSS
flame scanner is housed in a 316 stainless steel enclosure
for extreme environments that can be found in marine
applications. 
Product Overview
The 95DSS3-1CEXSS scanner utilizes advanced techniques for discrimination
and integrate the flame detection, 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.
95DSS3-1CEXSS is a dual cell scanner utilizing UV and IR detectors and a
stainless steel housing which includes CE and ATEX ExdIIC approvals when
suitable connectors and fittings are used. Model 95DSS3-1CEXSS includes the
alpha-numeric VFD Display and Keypad.
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
