Fireye 95UVS2-1 Flame Scanner – Obsolete UV Flame Detector Spare Part

When a Fireye 95UVS2-1 flame scanner fails in an operating boiler or burner management system, the consequences extend far beyond a single component replacement. Combustion control systems built around Fireye's legacy UV scanner architecture — including installations integrated with Fireye E110, E120, and EP260 programmer series — cannot simply be swapped to a modern alternative without triggering a full system re-engineering project. Conservative estimates place the cost of such an upgrade at USD $150,000 to $500,000 per burner train, factoring in new controller hardware, field wiring modifications, safety logic re-validation, regulatory re-certification, and production downtime. DriveKNMS holds verified physical stock of the 95UVS2-1. For plant managers operating aging combustion infrastructure, this is not a commodity purchase — it is asset protection.

Technical Specifications

Note: Electrical parameters such as supply voltage and output signal type vary by installation configuration. Consult your original system documentation. DriveKNMS does not publish unverified specifications.

Solving the Discontinued Hardware Crisis

The Fireye 95UVS2-1 was designed for a generation of burner management systems that prioritized deterministic, hardwired safety logic over software-defined control. That design philosophy is precisely why these systems remain in service decades after installation — they are reliable, well-understood by maintenance teams, and carry a safety validation history that a replacement system would need years to replicate.

The discontinuation of the 95UVS2-1 does not invalidate the system it serves. It creates a procurement problem. Fireye no longer manufactures this scanner, authorized distributors have exhausted their pipeline stock, and the secondary market is populated with units of unknown provenance. For a plant running continuous production — a refinery, a chemical plant, a district heating facility — an unplanned burner shutdown caused by scanner failure can cost tens of thousands of dollars per day in lost output, emergency contractor fees, and regulatory reporting obligations.

The strategic response is not to accelerate a capital upgrade project under emergency conditions. It is to secure verified replacement units now, while controlled sourcing is still possible. A stock of two to three 95UVS2-1 units, properly stored, extends the operational life of the associated burner management system by five to ten years at a fraction of the cost of system replacement. This is the core logic of obsolete parts inventory management: the cost of the part is negligible relative to the cost of the failure it prevents.

Condition & Reliability Assurance

DriveKNMS applies a five-stage quality process to all obsolete flame scanner units before dispatch:

• Visual and mechanical inspection: Housing integrity, lens condition, and connector pin examination for corrosion, oxidation, or mechanical deformation.
• Electrolytic capacitor assessment: Aging capacitors are a primary failure mode in stored electronics. Units are evaluated for capacitor condition; where degradation is identified, this is disclosed to the buyer.
• Firmware and version verification: Where applicable, firmware revision is confirmed against Fireye documentation to ensure compatibility with the target programmer series.
• Functional bench test: UV response is verified using a controlled UV source prior to packaging.
• Packaging for long-term storage: Units are packed in anti-static, moisture-barrier packaging suitable for extended shelf storage in a controlled environment.

Condition grade (New Old Stock or Tested Refurbished) is disclosed on the invoice. No unit is shipped without passing all five stages.

Key Features for System Maintenance

• Drop-in replacement: The 95UVS2-1 installs directly into existing Fireye programmer mounts without mechanical modification.
• No reprogramming required: The scanner interfaces with the existing programmer via the original hardwired signal path. There is no firmware to configure, no IP address to assign, no commissioning software required.
• Avoids engineering re-scope: Substituting a modern flame detection system requires P&ID revision, safety function re-validation under IEC 61511, and in many jurisdictions, third-party audit. A like-for-like 95UVS2-1 replacement requires none of this.
• Maintains existing safety certification baseline: The burner management system's safety integrity level (SIL) assessment remains valid when the replacement component is identical to the original design specification.
• Supports planned maintenance scheduling: With a spare unit on hand, scanner replacement can be scheduled during a planned outage rather than executed as an emergency repair.

FAQ

What warranty applies to an obsolete part like the 95UVS2-1?
DriveKNMS provides a 90-day functional warranty on all tested refurbished units and a 30-day warranty on New Old Stock units. Warranty covers functional failure under normal operating conditions and excludes damage caused by incorrect installation or system overvoltage.

How do I confirm the unit is genuine Fireye manufacture?
All units supplied by DriveKNMS carry original Fireye part markings. Upon request, we provide high-resolution photographs of the unit label, date codes, and connector assembly prior to shipment. Buyers are encouraged to cross-reference against Fireye's published part documentation.

Should I purchase more than one unit?
For any system where the 95UVS2-1 is a single point of failure — which is the case in most single-burner installations — holding a minimum of one spare unit on-site is standard maintenance practice. For multi-burner installations or facilities without rapid procurement capability, two to three units is a defensible inventory position. The cost of storage is trivial relative to the cost of an unplanned outage.

Can DriveKNMS source other Fireye obsolete parts?
Yes. DriveKNMS specializes in hard-to-find and discontinued industrial automation components across multiple brands. Contact us with your part number for a sourcing inquiry.
