OVERVIEW 3 Overview The Honeywell Analytics FSL100 series of Flame Detectors comprises three models:  FSL100-IR3 Triple Infrared flame detector FSL100-UV Ultraviolet flame detector FSL100-UVIR Ultraviolet and Infrared flame detector These flame detectors monitor an area by looking for the presence of invisible infrared or ultraviolet light that occur outside the frequency range occupied by visible flames, and they can do this in the presence of interference (sunlight, smoke, dust, vapour etc.) to determine whether or not a fire is actually present within their field of view. All three detectors...

INSTALLATION 4 Mechanical Installation This chapter describes the mechanical requirements for installing FSL100 Series Flame Detectors. Electrical installation is discussed in the next chapter. 4.1 Siting The number, type and placement of fire detectors and alarm control systems should be determined in consultation with Honeywell Analytics specialist technical advisors and Site specialists. Remember that the FSL100 series are flame detectors only; they cannot detect flammable gas or dust atmospheres. Please contact Honeywell Analytics if you need a flammable atmosphere detection system. Generally...

INSTALLATION 4.4 Cone of Vision The FSL100 flame detector has a cone of vision of 90° so it can monitor an area extending from floor to ceiling and extending to approximately 23 m (FSL100-UV and UVIR) or 35 m (FLS100-IR3). 4.5 Shadow Effect If monitoring a solid object, the mounting height (h d) of the flame detector should be at least twice the height (ho) of the highest object in the monitored zone: Detector height (hd) = 2 x height of the highest object (ho) Figure 4. Shadow effect Shadow Effect FSL100 Series Flame Detectors Technical Handbook

INSTALLATION To avoid the shadow effect (in zones that cannot be fully monitored by a solo flame detector) place a second flame detector in the opposite corner. Shadow Cancelling 4.6 Mounting Below a Ceiling Smoke rises and can form a layer at ceiling height long before naked flames are visible. Dense smoke can block some of the wavelengths of light given off by flames, and this can ultimately decrease the sensitivity and speed of the flame detector. To avoid the risk of smoke blocking their fields of view, you should mount the FSL100-IR3 flame detectors at least 0.5 m (2 ft), and the FSL100-UV...

INSTALLATION 4.7 Vote Count FSL100 flame detectors will not give an alarm until several different alarm criteria occur at the same time, and the probability of a false alarm is very low. The flame detector is therefore suitable for relay activated actions (i.e. drenching) based on the signal of one flame detector. However, ‘voting’ may be demanded in a functional specification, in which case the ‘voting-system’ may be applied; i.e., the flame detectors may be mounted in multiples, as shown in the example below where an alarm output would be dependent on the controller receiving confirmatory alarm...

INSTALLATION 4.8 Weather Protection It is recommended to place a hood or shield above the flame detector to protect it from sunlight, rain and snow. A stainless steel metal plate of approximately 30 x 30 cm (12 x 12 in) can be mounted directly above the flame detector without inhibiting its field of view. A similar plate can be used to shield it from potential false alarm sources such as smoke-stack flares. 4.9 Hot Work Flame Detectors may alarm in the presence of hot work, for example a welding operation, and this must be taken into account when doing Hot Work risk assessments and when issuing...
