4 Common Types of Flame Detectors

Posted on 04, Aug. 2023

Before any alarms can sound or fire concealment frameworks can enact, something should recognize that fire is present. Generally speaking, that something is a fire indicator.

Underneath, we will discuss what a fire detector is, what types are accessible, and how to figure out which one might be best for your office.

What Is a Flame Detector?

A flame detector is your offices first line of safety against fire. A sensor intended to recognize the presence of fire immediately, so you can respond as fast and suitably as could be expected.

Commonly, a flame detector just not identifies the presence of a fire, but also, briefs your fire security systems and suppression systems to trigger. This could incorporate any of the following

  • Sounding fire alarms systems
  • Alerting your central station monitoring system and the first local responder.
  • Activating your fire suppression systems(extinguishers, sprinklers, etc.)
  • Deactivating your gas and fuel lines

4 Common Types of Flame Detectors

Something significant to be familiar with fire detectors? Not all fire detectors are made equivalent. There are various brands and models available — and keeping in mind that they all work to achieve similar objectives of recognizing fires, they work, perform, and respond to specific dangers unexpectedly. It is important to know the details regarding every one of them, so you can choose the one that best suits your facilities needs.

Let us take a look at  five of the most common types of fire detectors as follows:

1. Ultraviolet (UV) Flame Detectors

Ultraviolet (UV) flame detectors recognize UV radiation the second a fire is touched off. Since most flames communicate UV radiation, these detectors are a good, dependable choice for some offices. They are also valuable for offices that are inclined to specific hazards like hydrocarbon, halogen, and metal fires.

UV flame detectors offer extraordinary awareness at brief distances, around 0-50 feet. In any case, their presentation is known to diminish at any length past that. They're also known to respond to electrical releases like lightning, so they are best kept in an indoor climate.

2. Infrared (IR) Flame Detectors

An infrared (IR) flame detector observes IR radiation. Hot gasses that are transmitted by flames produce exceptional examples in IR frequencies, which can be found on a thermal imaging camera inside the detector. All things considered, IR flame detectors require the flickering movement of a flame before they can detect and respond to a fire.

IR flame indicators are also habitual guilty parties of false alarms. This is because other hot gasses and surfaces not brought about by a fire (ovens, heat lights, and so on) can set off their reaction.

3. Ultraviolet/Infrared (UV/IR) Flame Detectors

Ultraviolet/infrared (UV/IR) flame detectors incorporate sensors for both UV and IR radiation. The two sensors work independently, as depicted previously. However, some additional hardware and wiring help the indicator cycle and assess the two signs. This helps dispel any problems that one sign or the other may provoke.

This supported resistance to false alarm systems permits UV/IR fire locators to be utilized in both indoor and open-air applications. In any case, it limits fire detection to incorporate flames that just transmit both UV and IR radiation.

4. Multi-Spectrum Infrared (MSIR) Flame Detectors

Multi-spectrum infrared (MSIR)flame detectors utilize numerous infrared wavelengths to further recognize fire-creating radiation from non-fire-creation radiation sources. They are equipped for responding rapidly to flames inside a distance of up to 200 feet, both inside and outside

MSIR flame detectors are also equipped for recognizing flames even in the midst of the smokiest of flames, and they are not liable to make deceptions due to lighting, sunlight, or other hot items in the surrounding environment.

5. Visual Flame Imaging Flame Detectors

Visual flame imaging flame indicators utilize charged couple device(CCD) picture sensors to recognize the presence of a fire. These sensors cycle the live video from the CCD to examine conceivable fire sources' shapes and development, which assists them in recognizing whether it's a genuine fire danger.

One benefit of this kind of flame detector is that it does not depend on the discharge of carbon dioxide or other burning items to identify fires. In any case, one drawback is that they are not equipped for recognizing fires imperceptible to the natural eye, similar to hydrogen flares.

How to Decide Which Flame Detector Is Right for Your Facility?

Since there are so many choices out there, it tends to be hard to know which type of flame detector is the most ideal decision for your office. Your best choice is to talk with a fire detection specialist, like our team at Buildmyinfra. They will be able to listen to your particular requirements and unique fire hazard, then, at that point, suggest a good solution.

But to give you a clear idea of what  type of flame detector you could require, there are a couple of main things to consider, including

  • Your facility has unique fire hazards and the kind of radiation those fires emit.
  • from Your facility environmental conditions.
  • Your  facility size (or the components of the protected area)
  • The significance of flame detector reaction time to your facility
  • The significance of flame detector false alarm rate to your facility


Regardless of your industry or application, your facility needs adequate fire security systems and that starts with fire detection. At Buildmyinfra Fire & Security Systems, we can help you find a high-quality flame detector that works for you.
