Built-In Verification for Indoor Applications

The CFD1-T adds automated optical self-test to the standard CFD platform. Detection performance, housing, and relay outputs are identical to the CFD1-S.

This configuration is selected when detectors are installed in locations with limited physical access, when scheduled manual testing is disruptive, or when facility specifications require ongoing automated verification of detector health.

Key Features

  • Automated Optical Self-Test: Periodically verifies sensor and optical integrity. Faults reported via relay output and LED indication.

  • UV/IR Multi-Spectrum Sensing: UV (185–260 nm) and IR (0.715–3.5 µm) 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.

Confirm CFD1-T Alignment With Your Application

If your project calls for indoor flame detection with automated verification, we can review the environment and confirm that the CFD1-T aligns with your system requirements.

The Engineering Behind the CFD1-T

The CFD1-T uses the same UV/IR detection core as the CFD1-S. The self-test function periodically verifies sensor and optical window functionality without requiring physical access, while internal diagnostics monitor system health and report faults through the relay output and LED indication.

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-T adds automated verification to Sierra’s indoor platform: reducing reliance on manual testing without adding unnecessary complexity.

Where the CFD1-T Fits Within Your Facility

Warehouses and Storage

Areas where flammable materials are present and detector access for manual testing is limited or disruptive.

Equipment Rooms

Enclosed spaces where automated health verification reduces maintenance interruptions.

Light Manufacturing

Indoor production areas within semiconductor, chemical, or oil & gas facilities where self-test supports ongoing compliance.
