Choosing the right Beam for a particular site depends on a number of criteria (which will be discussed in the Blog).
While both types of Beam technology, Reflective and End to End are equally good at detecting smoke, each type has applications to which it is more suitable than the other type.
The sensitivity of all Talentum Flame Detectors is based on the size of the flame and the distance that flame is away from the Flame Detector.
For example, while a Flame Detector will pick up a cigarette lighter flame at 1M, the same size flame would not be detected at a distance of 8M.
There are two types of Fire Panels, Conventional types which have ‘Zones’ which are connected directly to devices such as Optical Beam smoke Detectors or Flame Detectors and Analogue Addressable types which have a loop bus onto which addressable devices can be connected.
Cleaning the Flame Detector, if it is high off the ground, may be difficult and or expensive, this is where the Flame Detector Air Purge kit comes in.
FFE make an Exd End to End Beam Smoke Detector, Fireray 3000 and Exd versions of the Talentum Flame Detector, IR2, IR3 and UV/IR2.
All Exd detectors are designed to be used in what are termed as ‘Hazardous Areas’ (Zone 1) and as such, must be installed as per the guidelines for such areas. Here is some additional information to be aware of when testing FFE Exd Flame Detectors and Beam Smoke Detectors.
Exd Flame Detectors.
The internal laser, which is fitted to two of the current beam smoke detectors in the Fireray range is primarily used for alignment. However, it also play's a major role in fault finding.
Once aligned, if the beam smoke detector is not mounted to a solid surface or structure (see other Blogs), it can go out of alignment due to building movement.
The Fireray 3000 ExD is an End to End Beam detector which is designed to be used in a Hazardous Area (Zone 1 and Zone 2).
Zone 1 is defined as: ‘An area where ignitable concentrations of flammable Gasses, Vapours or Liquids are likely to exist under normal operating conditions’.
Zone 2 is defined as: ‘An area where ignitable concentrations of flammable Gasses, Vapours or Liquids are not likely to exist under normal operating conditions’.
The biggest rival technology to Optical Beam Smoke Detectors for detecting smoke/fires in warehouses & large open areas is the Aspirating Smoke Detector (ASD).
While ASD is very sensitive in comms rooms and data centres (for which they were originally developed) in the warehouse and in wide open areas, this advantage is lost when compared to Beam Detection.
