Fireye 95DSS2E-1 Enhanced InSight Flame Scanner with Dual IR/UV Sensors

Product Overview

The Fireye 95DSS2E-1​ is an Enhanced Model InSight flame scanner developed by Fireye (USA) as part of the InSight Type 95 series of microprocessor-based flame detection devices. Engineered for single and multi-burner industrial combustion systems, the Fireye 95DSS2E-1​ integrates both ultraviolet (UV) and infrared (IR) solid-state sensors into a single ruggedized cast-aluminum housing, enabling reliable detection of target flame presence or absence across gas, oil, coal, and mixed-fuel applications. By incorporating an internal flame relay with adjustable ON/OFF thresholds, the Fireye 95DSS2E-1​ eliminates the need for a separate remote flame amplifier—dramatically simplifying Burner Management System (BMS) architecture and reducing total installed cost.At the core of the Fireye 95DSS2E-1​ lies a powerful microprocessor that measures the modulation amplitude (i.e., the “flicker” characteristic) of the observed flame. During commissioning, the scanner selects the optimal modulation frequency from 21 available flame flicker frequencies (23–179 Hz) to achieve the best flame ON/OFF discrimination. The “S2” expanded model supports Fireye’s proprietary AutoTune function, which automatically selects the best modulation frequency and sensor gain while retaining manual override capability for expert tuning. The “E” designation denotes the Enhanced feature set, including remote communication via Fireye dedicated software for configuration and monitoring.Physically, the Fireye 95DSS2E-1​ features a grey polyester powder-coated cast aluminum housing rated NEMA 4X / IP66, with a 12-pin quarter-turn quick-release connector (the “-1” suffix denotes this 12-pin configuration). An 8-character alphanumeric LED display and 4-button keypad on the front face allow local setup, diagnostics, and real-time signal viewing without removing the scanner from the burner front. The unit performs electronic self-check without any mechanical shutter, improving long-term reliability by removing moving parts from the safety-critical inspection path. With a wide ambient operating temperature range of -40°C to +65°C, 0–95% non-condensing humidity tolerance, and hazardous-area certifications (Class I Div. 2, Class II Div. 2), the Fireye 95DSS2E-1​ is purpose-built for the harshest industrial combustion environments.

Main Features and Advantages

The Fireye 95DSS2E-1​ delivers a compelling combination of dual-spectrum intelligence, integrated amplification, and industrial ruggedness that sets it apart in the flame detection landscape. The cornerstone advantage is its dual IR/UV sensor architecture. The UV sensor responds to 295–320 nm radiation, making it ideally suited for gaseous and light-oil fuels where UV emission is strong at ignition. The IR sensor covers 700–1700 nm, excelling at detecting oil and coal flames rich in infrared energy. By fusing both spectra, the Fireye 95DSS2E-1​ achieves superior discrimination in mixed-fuel applications, reliably distinguishing true flame from furnace wall radiation, hot refractory, or stray background illumination that would fool single-spectrum detectors.Integrated flame amplification is another decisive strength. Unlike conventional flame scanning systems that require a separate remote amplifier module connected via a long signal cable, the Fireye 95DSS2E-1​ embeds the entire amplification and relay logic inside the scanner head. This design eliminates a classic failure point—the noise-prone long cable run between scanner and amplifier—while freeing up panel space and reducing wiring cost. The internal flame relay features adjustable ON/OFF thresholds, allowing the Fireye 95DSS2E-1​ to be fine-tuned to the exact flame signature of each specific burner.Intelligent AutoTune capability elevates the Fireye 95DSS2E-1​ above ordinary flame scanners. During setup, the scanner evaluates the target flame across 21 selectable flicker frequencies (23–179 Hz) and automatically locks onto the modulation frequency that yields the sharpest contrast between flame-present and flame-absent states. Sensor gain is likewise auto-optimized, while still permitting manual override for specialist applications. The result is a Fireye 95DSS2E-1​ that can be commissioned in minutes rather than hours, with markedly lower false-trip rates.The electronic self-check mechanism of the Fireye 95DSS2E-1​ represents a major reliability improvement over legacy mechanical-shutter designs. By eliminating moving parts from the safety inspection path, the scanner removes the primary wear item that historically limited flame scanner lifespan. Continuous electronic diagnostics monitor internal circuit health and report faults via the 8-character LED display and the fault relay output, enabling predictive maintenance before a safety-critical failure can occur.Local operator interface is exceptionally user-friendly. The Fireye 95DSS2E-1​ places an 8-character alphanumeric LED display and a 4-button keypad directly on the scanner front face, allowing technicians to read flame signal strength, scroll through diagnostic messages, and adjust setpoints without a laptop or separate handheld communicator. For advanced users, the S2 enhanced communication capability supports remote configuration and real-time monitoring via Fireye’s dedicated PC software, integrating seamlessly with modern BMS and plant asset management networks.Industrial robustness rounds out the value proposition. The cast aluminum housing with grey polyester powder coating, NEMA 4X / IP66 sealing, and hazardous-area certifications make the Fireye 95DSS2E-1​ impervious to dust, moisture, vibration, and explosive atmospheres. With 4 programmable parameter profiles (A/B/C/D), a single Fireye 95DSS2E-1​ can store multiple burner configurations, simplifying spare management and enabling rapid burner changeovers in multi-fuel plants.
