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.
