Honeywell FSL100 series flame detector



Honeywell FSL100 series flame detector

Product Overview

The Honeywell FSL100 series flame detector includes three types: UV, UV/IR, and IR3, with powerful, fast, and reliable flame detection capabilities, suitable for a variety of scenarios. Its design is compact and lightweight, easy to install, and can work in harsh indoor and outdoor environments as well as potentially explosive atmospheres. Through precise sensing and signal analysis technology, it achieves rapid fire detection and effectively reduces false alarms.

Core advantages

Wide applicability: covering UV, UV/IR, IR3 types, capable of detecting various sources of fire such as hydrocarbons and non hydrocarbons, suitable for potential explosive environments and indoor and outdoor scenes, providing high visibility red or low profile white models.

Excellent performance: Complies with EN54-10 and FM3260 flame detector standards, with comprehensive automatic self checking function and supports remote manual self checking options.

Fast and reliable: Using high-speed sensors and microprocessors, combined with complex analysis algorithms, continuous health monitoring is carried out to effectively suppress false alarms.

Reduce lifecycle costs: The components have a long lifespan, have pressure compensation function to avoid pollution, and provide a 2-year warranty.

Easy to install and use: Comes with standard relays and milliampere output, featuring a lightweight glass fiber reinforced plastic (GRP) housing, pre molded knockout design, optional rotating mounting bracket, and long-distance test light.

Characteristics of each model

FSL100-UV：

Suitable for indoor scenarios such as fume hoods and hydrogen storage areas.

Good detection effect on low-temperature combustion substances (such as sulfur).

Can detect heavy hydrocarbons (wood, paper, petroleum, etc.), light hydrocarbons (methanol, methane, etc.), and hydrogen fires.

Has good resistance to artificial light sources such as direct/reflected sunlight, fluorescent lamps, and glass covered halogen lamps.

FSL100-UV/IR：

Improve false alarm suppression capability by analyzing flame flicker frequency.

The dual sensing method can effectively detect various hydrocarbon and non hydrocarbon fires.

Has good resistance to sunlight, artificial light sources, electric arcs and discharges (generated by static electricity or motors), and welding radiation at a distance of more than 10 feet.

FSL100-IR3：

Analyze flame flicker frequency to reduce false alarms, especially suitable for liquid hydrocarbon fires and smoke fires.

Less affected by window pollution or smoke.

The anti-interference ability is similar to UV/IR, especially suitable for fire scenarios with high smoke levels.

Applicable scenarios

It covers various scenarios such as aircraft hangars, atriums, battery storage rooms, biogas facilities, parking lots, clean rooms, CNG refueling stations, cold storage, engine rooms, laboratories, loading and unloading docks, oil and gas pipeline pump stations, outdoor storage areas, etc. Different models have slightly different applicable scenarios (please refer to the application table in the document for details).
