Straightforward Detection for Indoor Applications

The CFD1-S is the standard configuration within Sierra’s CFD product line. It delivers UV/IR optical flame detection for indoor environments where flammable materials are present but hazardous-location or chemical-resistant equipment is not required.

Factory configured with no user-adjustable settings. Fire and Fault relay outputs. Integrates directly into fire alarm panels and monitoring systems.

Specification Sheet

Key Features

  • UV/IR Multi-Spectrum Sensing: UV and IR sensors. Detects a 4-inch IPA fire at 10 feet and a 1 sq. ft. heptane fire at 40 feet: both within 3 seconds.

  • 120° Conical FOV: Wide field of view for coverage across equipment rooms, storage areas, and enclosed industrial spaces.

  • FR Polypropylene Housing: UL 94 V0 flammability rated. Lightweight at approximately 1 lb. Dimensions: 3.4 × 5.6 × 1.0 inches.

  • Simple Integration: Fire and Fault relay outputs. No user-adjustable settings — factory configured for stable, predictable operation.

The Engineering Behind the CFD1-S

The CFD1-S uses UV and IR sensors to identify flame signatures while filtering common false sources. All settings are factory configured — there are no DIP switches or field-adjustable parameters. The detector is built for stable, predictable operation in controlled spaces.

What Sets Sierra Apart

Sierra Safety Technology has manufactured flame detection equipment for nearly 40 years with zero product recalls and zero failures resulting in loss of life. The CFD1-S brings that same engineering foundation to indoor environments that don’t require explosion-proof or chemical-resistant construction.

Where the CFD1-S Fits Within Your Facility

Warehouses and Storage

Areas where flammable liquids or materials are stored but atmospheric classifications don’t require hazardous-location equipment.

Equipment Rooms

Enclosed spaces housing mechanical, electrical, or process equipment that require flame detection coverage.

Light Manufacturing

Indoor production and assembly areas within semiconductor, chemical, or oil & gas facilities where the space itself is not classified.
