‘Why is the Talentum flame detector so fast?’

All Talentum Flame Detectors have a fast response to Flame, but some are faster than others. These are the reasons why…

To go into a Fire condition, all Talenetum Flame Detectors need is A) an Infra-Red (IR) or IR and Ultra Violet (UV) light source and B) that light source must flicker.

The speed they respond to the light source depends on what type and how many sensors they have fitted.

Spark Detector (Rear Viewing). This Flame Detector only has one IR sensor and so will respond instantaneously to a flickering IR source.

 

IR2. This is the quickest of the Standard Front Facing Flame Detectors as it only has two IR sensors. Both have to Detect an IR source (one after the other) with flicker to Alarm.

 

IR3. This is the slowest of the Standard Front Facing Flame Detectors. It has three IR sensors which have to Detect an IR source (all three have to Detect one after the other) with flicker to Alarm.

 

UV/IR2. This Flame Detector uses both UV and IR sensors to Detect Flame. This Flame Detector is quicker to Alarm than the IR3 because the UV sensor is much faster to respond to a light source than the IR sensors. It must have all three sensors responding to go into Alarm.

 

There is also a ‘specialist’ Super-Fast version for the Bloodhound SSC which is attempting to beat the land speed record in 2017 and it works like this:

Due to the fact that this Flame Detector needs to respond very fast to any ‘flame’, it has a restricted operating range and a narrower operating coverage. This is not important because this Flame Detector is designed to work in confined spaces. The Flame Detector is designed to work on power up and only has a UV and one IR sensor. Due to the fact that it needs to respond instantaneously to any ‘flame’, as soon as UV and IR signals are detected, the Flame Detector will signal a ‘Fire’. It does not need to see a flickering source.

 

As we can see, there is a Flame Detector suitable for all the major requirements within the industry and there are specialist versions where speed of detection is paramount.
