1. Introduction
The FlameSpec-UV-IR flame detector provides ultra-fast response, high performance and reliable detection
of a large variety of fires including hydrocarbon fires (visible and non-visible), as well as hydrogen fires (FLS-
UV-IR only).
The detector addresses slow growing fires as well as fast eruptions of fire using improved UV-IR technology.
The detector operates in all weather and light conditions. It will automatically record a fire event (1 min
pre/post alarm) using the internal data logger.
This manual covers two UV/IR detector models:
1. FLS-UV-IR: Hydrogen and hydrocarbons flame detection. Spectrum response of IR radiation in the
3.0-4.0 micron range
2. FLS-UV-IR-F: Hydrocarbon flame detection. Spectrum response of IR radiation in the 4.0-5.0 micron
range
1.1 Key Features
•High immunity: To false alarm
•Ultra-fast detection mode: Within 5 milliseconds for Hydrogen fireballs or explosions
•High sensitivity: Up to 100 ft. (30m) for a 1ft2 (0.1m2) n-heptane pan fire
•Built-in-Test (BIT) - Automatic and manual self-test of window cleanliness and the overall operation of the
detector.
•Window heater to avoid condensation and icing.
•Tilt mounting bracket can be connected either above or below the detector.
•UV and IR warning levels - 0-20mA - current output warning when elevated UV or IR radiation is
detected.

1.2 Model Number Description
Model No are defined as follows:
FLS-UV-IR-F - X S X 1
FLS-UV-IR - X S X 1
1 -M25
2 - ¾” NPT
A –FM, ATEX
1.3 Internal tests
During normal operation, the flame detector performs self-tests of its optics, electronics and software. These
include a periodic BIT (Built-In-Test) in which the sensors and window cleanliness are tested. Any detected
fault is indicated as shown in Table 4 (in section 5.1). During “Dirty Window” fault the detection sensitivity is
significantly reduced, while “Fault” refers to critical faults which totally prevent flame detection.

2Installation
The detector is intended for use as part of a complex system where many detectors and other
devices are integrated with different vendors’systems and interface communication to a variety of
different types and configuration control units and panels including control of instrumentations
computers. This chapter does not attempt to cover all of the standard practices and codes of
installation. Rather, it emphasizes specific points of consideration and provides some general rules
for qualified personnel. You must always observe special safety precautions.
2.1 General Considerations
This section includes important information.
To help obtain optimal performance, the detector should be aimed toward the center of the hazard
or area to be monitored and protected ("detection zone") and have, to the extent that is required, an
unobstructed view of the protected area. Whenever possible, the detector face should be tilted
(aimed) down at an angle to prevent the accumulation of dust and dirt.
Do not start an installation until the detector task definition, system configuration, installation
location and coverage considerations have been considered and clearly defined by the relevant
designers.
To ensure optimal performance and an efficient installation that fits your needs and complies with
the requirements, the following guidelines should be addressed:
Sensitivity
To determine the sensitivity level, the following issues should be considered:
▪The size of the fire to be detected at the determined distance.
▪The type of flammable fuel.
Spacing and Location
Consider the following factors when determining the number of detectors and their
locations in the protected area:
▪The size and shape of the protected area
▪The nature of the hazards, including materials stored or used and the protected objects
▪The sensitivity of the detectors
▪If there are any obstructed lines of sight
▪The field of view of the detectors

Environment
▪Environmental conditions including but not limited to dust, snow or rain can reduce the
detectors sensitivity and require additional maintenance.
Welding
▪Arc welding should not be performed within 10 ft. (3m) of the detector. It is
recommended that the system be inhibited during welding operations in situations
where the possibility of a false alarm cannot be tolerated.
▪Gas welding requires a system inhibit, since the gas torch is an actual fire.
▪Arc welding rods can contain organic binder materials in the flux that burn during the
welding operation and are detectable by the device.
▪Welding rods with clay binders do not burn and should not be detected. However, a
system inhibit is always recommended, since the material being welded may be
contaminated with organic substances (paint, oil, etc.) that will burn and may be of the
size that should be detected.

2.2 Preparations for Installation
The installation must comply with local regulations and standards applicable to flame detectors (e.g.,
NFPA 72) and all local and common engineering practices. It is recommended to consult with a safety
engineer.
The detectors can be installed with the use of general-purpose common tools and equipment.
Prior to installation:
•Verify the appropriate purchase order.
•Record the part and serial numbers of the detectors and the installation date and log.
•Visually inspect the detector prior to installation to make sure it is intact.
•Make sure that you have all the components and tools required to complete the
detector installation readily available before beginning installation. In cases where you
cannot complete the installation in a single session, secure and seal the detectors and
conduits before leaving the site.
•Use color-coded conductors or suitable wire markings or labels for the wiring. You may
use 12 to 20 AWG (2.5 𝑚𝑚2to 0.35 𝑚𝑚2) wires for the site wiring. The selection of
wire gauge should be based on the number of detectors used on the same line and the
distance from the control unit, in compliance with specifications.
•Use wire rated for a temperature of at least 111°C, which is 5°C above the rated service
temperature.
2.3 Required Tools
The detector can be installed using general purpose common tools as defined in the following table:
Tool
Function
Hex. KEY 6 mm
Vertical alignment
Hex. KEY 10 mm
Horizontal alignment
Wrench 13 mm
Mounting the detector
Flat Screwdriver 6 mm
Ground screw connection
Flat screwdriver 3.5mm

2.4 Certification Instructions
Warning: Do not open the detector, even when isolated, when flammable atmosphere present.
•The equipment may be used in hazardous areas with flammable gasses and vapors with
apparatus groups IIC, IIB and IIA and with temperature classes T1, T2, T3, T4 and T5. See
details of the explosion proof approvals in section 6.6.1.
•The equipment is certified for use in ambient temperatures in the range of -67°F to
+167°F (-55°C to +75°C) or -67°F to +185°F (-55°C to +85°C) and should not be used in
temperatures outside this range.
