Flame Detectors

Buy flame detectors for fast detection of open flaming fires in industrial and hazardous areas: triple IR (IR3), dual IR, UV and UV/IR detectors in standard, flameproof (Ex d), intrinsically safe (I.S.) and marine versions, plus test lamps, brackets and weather shields.

How to choose a flame detector

• Sensor type. Triple IR detectors offer strong false-alarm immunity and see through smoke and light contamination. UV detectors respond quickly in clean, enclosed areas but can be triggered by arc welding. UV/IR detectors need both signals to alarm, reducing false alarms.
• Fuel. Check which fires each model is designed for. Some are for hydrocarbon fires only, while hydrogen versions such as the Fike IR3-H2 detect near-invisible hydrogen flames.
• Area classification. In zoned areas use Ex d (flameproof) or I.S. detectors rated for the zone; I.S. detectors need a suitable barrier or isolator.
• Range and panel. Check the detection distance and field of view, and whether you need an addressable detector such as Apollo XP95 or a conventional one.
• Testing. Plan for a compatible test source, such as the Talentum Test Torch, Honeywell TL-2055 hazardous area lamp, SENSE-WARE UV/IR test lamp or Fike FlameSpec simulator kit.

Flame detector FAQs

What is a flame detector used for?

A flame detector responds to the optical radiation from a flame rather than to smoke or heat. It is used where fire can develop quickly with little smoke, such as fuel stores, spray booths, aircraft hangars, generator rooms and petrochemical sites.

How does a flame detector work?

Optical sensors look for the wavelengths flames emit, such as the 4.3 µm infrared band from hydrocarbon fires, and for the 1–15 Hz flicker typical of flames. Checking several signals lets the detector ignore sunlight, hot objects and lighting.

How do you test a flame detector?

Use a test lamp or flame simulator matched to the detector type and, in hazardous areas, one rated for the zone. Many detectors also have a built-in self-test. Follow the manufacturer's test procedure.
