The CFD: Your Commercial Optical Flame Detector
Straightforward flame detection for indoor environments that still demand dependable performance.
Invest in Indoor Flame Detectors From an Industry Leader
Not every application needs an explosion-proof housing or chemical-resistant construction. Sometimes, you just need reliable flame detection that works exactly as expected in a controlled, indoor environment.
That’s where the CFD series fits. It brings Sierra’s proven design philosophy into commercial and light industrial applications where consistency, simplicity, and long service life matter.
Simple by Design. Reliable by Nature.
The CFD line is intentionally straightforward. No overengineering. No unnecessary features. Just optical flame detection built on the same engineering principles Sierra has used for decades.
It’s a solid choice when indoor spaces still involve flammable liquids, processes, or equipment, but aren’t classified as hazardous locations.
Explore Our CFD Options
The CFD product line includes two configurations designed to support different testing and maintenance preferences, while keeping installation and integration simple.
Standard (CFD1-S)
The CFD1-S is the standard, no-frills option for indoor flame detection. It’s designed for facilities that want reliable detection without automated testing requirements. This configuration is commonly used in warehouses, light manufacturing areas, storage facilities, and other indoor environments where flame detection is part of a broader safety strategy.
Self-Test (CFD1-T)
The CFD1-T adds automated self-testing for facilities that prefer built-in verification of detector functionality. This option reduces the need for manual testing and supports ongoing operational confidence. It’s often selected when access for routine testing is limited or when automated diagnostics are preferred.

A Practical Option Across Demanding Industries
While CFD is designed for non-hazardous indoor environments, it still finds a home across semiconductor facilities, oil and gas operations, and chemical plants where controlled indoor spaces require dependable flame detection.
It’s a practical option when the environment doesn’t call for heavy-duty protection, but reliability still isn’t optional.
