Product Introduction
The Fireye 95UVS4-1WINC represents the next generation of combustion safety monitoring. Belonging to the InSight Series 4 family, this scanner is a fully digital, microprocessor-based device that utilizes advanced Digital Signal Processing (DSP) to measure the amplitude of flame modulations (the flame’s “flicker”). Unlike traditional analog scanners, it offers superior discrimination against background radiation and significantly higher immunity to electromagnetic interference.
The “-1WINC” suffix denotes a pre-wired, integrated cable and plug design. This provides a plug-and-play installation experience, ensuring a reliable, sealed connection and eliminating costly field wiring errors. Equipped with HART communication, operators can remotely configure parameters, access diagnostic data, and perform predictive maintenance without entering hazardous areas. Its dual-line OLED display and 5-button keypad allow for intuitive local setup, including 21 selectable modulation frequencies and Auto Config capabilities.
QA & Testing SOP
As a SIL3-rated safety device, the 95UVS4-1WINC requires rigorous functional validation. We verify both the optical sensor and the digital communication stack.
- Anti-Counterfeit & Visual Audit: We inspect the Fireye housing, verify the 95UVS4-1WINC part number, and check the integrated cable, plug, and OLED display for physical damage.
- Power & Self-Diagnostic Test: We apply 24 Vdc to verify the scanner boots correctly, passes its internal electronic self-check, and displays system status on the OLED screen without triggering a Fault Relay.
- HART Communication Validation: We connect a HART communicator to verify the module successfully transmits digital data, responds to remote commands, and reports accurate diagnostic information.
- Relay & Analog Output Test: We simulate flame conditions to verify the Safety Relay and Fault Relay switch correctly, and confirm the 4-20 mA output scales accurately.
- ESD Safe Packaging: The DSP microprocessor and UV sensor are highly ESD sensitive. We pack in anti-static shielding bags with desiccant to prevent latent semiconductor damage.

Installation Pitfalls & Guide
❗ Pre-Wired Cable Handling: The integrated cable (-1WINC) is designed for direct plug-in. Never cut or splice this cable. Ensure the connector is fully seated and locked to maintain the IP66/NEMA 4X environmental seal.
❗ Auto Config & Learn Mode: The scanner features an Auto Config capability that automatically selects the optimal modulation frequency and sensor gain. Always utilize this feature during commissioning to ensure the best flame ON/OFF discrimination. Manual override is available but should only be used if Auto Config fails.
❗ Proof Testing: To maintain SIL3 compliance, you must perform regular proof tests. This includes an Active Flame OFF test (shutdown burner to verify flame loss signal) and an Active False Flame test (verify no flame signal prior to startup).
❗ HART Network Configuration: When connecting to a HART network, ensure the loop resistance is between 250 and 1100 ohms. Improper loop resistance will cause communication dropouts and prevent remote diagnostics.
Replacement SOP:
- Pre-Install: Document the existing HART tag, configuration files, and place the burner management system in bypass/maintenance mode.
- Removal: Disconnect the integrated plug; unthread the scanner from its mounting bracket.
- Install: Thread the new 95UVS4-1WINC into the bracket; reconnect the integrated plug securely.
- Power-On Test: Apply 24 Vdc; verify OLED display initializes; run Auto Config to calibrate to the flame; verify HART communication and relay outputs before removing bypass.
Technical FAQ
What is the main difference between the 95UVS4-1WINC and older 95DSS3 models?
The primary difference is digital intelligence. The 95UVS4-1WINC utilizes Digital Signal Processing (DSP) and HART communication, offering superior anti-interference capabilities, remote diagnostics, and predictive maintenance. The 95DSS3 series is an older analog-style device lacking these advanced smart features.
What does the “WINC” in the part number mean?
“WINC” stands for “Wired Integrated.” It means the scanner comes with a factory-attached, pre-wired cable and plug, providing a plug-and-play installation that guarantees a reliable, sealed connection and saves field wiring labor costs.
Does this scanner require a separate flame amplifier or switch?
No. The InSight Series 4 integrates the flame detection, amplification, safety determination, and flame switch functions directly into the single detection head. No separate amplifier or flame switch module is required.
Can this scanner be used in hazardous areas?
Yes. The 95UVS4-1WINC holds multiple worldwide safety agency approvals, including UL Hazardous Locations (Class I Div 2, Groups A, B, C, D) and ATEX/IECEx certifications, making it suitable for a wide range of hazardous industrial environments.
Why is this sold as new surplus?
This unit was pulled from sealed OEM overstock or an unfulfilled project before installation. We test it electrically to verify DSP functionality, HART communication, and relay integrity, but we aren’t replacing internal components. You are getting unused factory hardware with original manufacturing tolerances at a fraction of the active OEM list price.
