Where can I find specifications for products & accessories?

All datasheets can be found at ffeuk.com go to the Talentum tab and select detector type, then go to resources and then datasheets.

Will flame detectors work in waste disposal sites?

In short, yes. Our IR2 and IR3 flame detectors provide fast detection response while operating through dust and mist without loss of performance or reliability.

How many flame detectors do I need for my application?

The answer to this will depend on the specific application. However, we offer the following guidelines to help you.


Know your Risk – Does your environment contain volatile substances or are you monitoring a metal process to check for ignition? Depending on your environment and its risks you will need different set-ups to make sure it’s fully protected.


Know your Model – Check out our flowchart of What Flame Detector Do I Need? This breaks down our entire range and what environments they protect.


Know your Flame – What size flame are you trying to pick up? Small flames need detectors ~1 meter (3 feet) away from the risk, while larger flames can be detected up to 25m (82 ft) or more if the flame is large enough.


Know your Measurements – Make sure you are aware of the size of the process or area you are looking to protect as this will affect the number of units needed for your installation.


Know your Obstructions – If you cannot see the flame, the detector cannot see it either. In any installation there are common obstructions to be aware of; people, vehicles, equipment, or internal building structures. Add additional flame detectors where temporary or permanent obstructions may occur and always test final installation in different locations to check your coverage is as intended.

What type of flames can your Talentum detect?

Our Talentum detectors look for flames across a broad spectrum of infrared and UV light (both invisible to the naked eye). Talentum flame detectors look for the flickering movement of a flame allowing our products to reduce the risk of false alarms, while being able to detect flames of both non-hydrocarbon and hydrocarbon fuels.

Can the Talentum Flame Detector Test Unit work with other types of detectors?

Our Flame detector test unit is designed to test our Talentum flame detectors, so we cannot guarantee cross compatibility or reliability with other types of flame detectors.

Can my flame detector work from behind glass or screen?

Yes, all models will work except for our UV/IR2 models, as UV light emitted from a flame can be absorbed by glass.

What type of cable do I need?

In the UK, you should use FP200 Fireproof cable or the Fireproof equivalent in your country.

What is the maximum cable length between the detector and Power Supply?

Using FP200, the maximum distance between the Controller and Detector is 100m, using USA Spec Fireproof cable, the distance is only 80m.

How do you align a flame detector?

Talentum flame detectors do not need to be aligned, simply pointed at a powered unit towards the risk or area being protected. So as long as your risk is in that 90° field of view, a flame will be detected by the unit and go into alarm (FIRE).

How do I know my flame detector is working?

We offer a Flame Tester unit that works with our entire range of flame detectors. It is advised that when testing your flame detector, you test with the same signal strength and range every time to gauge the effectiveness and functionality more accurately.

How often should I test my flame detector?

We recommend you test your flame detectors at least every 12 months – this can vary depending on site requirements, local laws and regulations and it is your responsibility to know these.


Our rule of thumb: if in doubt, test it. Record it.

How do I wire to the Fire Panel?

The Flame detector won’t go into Fire or Fault when tested. What do I do?

When testing a Talentum Flame Detector, you should only use one of the following tests:

1) Modified Test Torch. The Test Torch with the Blue Filter on the end should not be used as this can give a false pass. There are two modified versions (Infra-Red only and both Infra-Red and Ultra-Violet Flame Detectors) of the Test Torch and these should only be used from now on.

2) A real flame of the appropriate size.

3) The Self-Test.

All these methods of testing should give a fire. If this does not work, then check that the window of the Flame Detector is clean (this is very important with the UV/IR2 but less so with IR2 & IR3). A dirty window will not affect the Self-Test function and the test is internal. If the Test Torch or Flame test fails, it is worth removing the cover to see if the window affected the test. Finally, check that the Fire Relay is working and that the Fire Resistor is fitted and the correct value for the Fire Panel. The only way to test for Fault is to power the Flame Detector down. If a Fault does not appear at the Fire Panel, check the Fault relay is opening.

What do I do if my detector’s power LED is not ‘ON’?

Power the unit at ground level and check for a GREEN LED again. It may be that the LED has moved from its position. Check your wiring is connected to power supply and voltage is 24Vdc. If the amber LED illuminates, then the unit is likely in failure.

What could be causing a false alarm?

False Alarms can be due to the wrong type of Flame Detector being used. As a rough rule of thumb, IR2 and IR3 Flame Detectors should not be used outside unless protected from direct sunlight, which can False Alarm Flame Detectors. To get an activation, all the sensors in the Flame Detector must be in Fire and then there must be a ‘flicker’ or modulation of that signal.


Inside False Alarms:
If a Flame Detector False alarms inside and the sun has not been shining directly onto it (if it is an IR2, IR3 or Spark Detector), the following has always been present:


Extreme Heat: a very hot process which gives of a heat of over 300 – 400 degrees can give off all the Infra-Red (and Ultra-Violet) needed to trigger a Flame Detector. The heat can also cause a haze to appear over the process, which combined with the IR will appear as a fire to a Flame Detector.


High Ambient Temperature: If the ambient temperature of the risk area gets above the maximum rated temperature (+55 degrees for the Standard and +85 degrees for the Enhanced version), the sensors are much more sensitive to an IR and can False Alarm.


Strong Infra-Red source: Flashing lights on a dump truck at a recycling centre False Alarmed an IR2 Flame Detector.


Outside False Alarms:

Sunlight: IR2 and IR3 Flame Detectors can be False Alarmed by direct or reflected sunlight shinning directly onto the front of the Flame Detector. Water can reflect sunlight, so puddles can cause problems to IR2 and IR3 Flame Detectors even if they are hidden from the sun. Use UV/IR2 Flame Detectors outside.


Reflections of steels: Outside metalwork has been known to False Alarm Flame Detectors by ‘bouncing’ IR through to the Flame Detector. Welding arcs can be picked up by Flame Detectors from the IR/UV signals being reflected by steel work.

My Fire Panel is saying the flame detector is in FIRE, but the detector is not showing a fire – what should I do?

The fire and fault relay could be wired incorrectly. Check against the wiring diagram below.
