1. Introduction
The FlameSpec-IR3-H2-HD flame detector will detect hydrogen and other “energy transition” fires quickly
allowing actions to be initiated to minimize the extend of the fire. The detector addresses slow growing fires as
well as fast eruptions of fire using improved IR3 technology. The detector operates in all weather and light
conditions.
As standard, a near infrared camera provides personnel the ability to see normally invisible fires like, hydrogen
and methanol.
The near IR camera allows rescue teams to be aware of the exact situation before entering the hazardous area.
The detector automatically records video of fire event (1 minute pre- and up to 3 minutes post-alarm initiation).
These features, along with the built-in event logger, provide an additional means to study the cause and
development of fire events.
As an option, the near IR camera can be changed to a color HD camera.
Key Features
•High immunity to false alarm
•Ultra-fast detection mode detection within 40 milliseconds for Hydrogen fireballs or explosions
•Detection of “energy transition” flames, like hydrogen, methane, syngas, and methanol
•High sensitivity –up to 100 ft. (30m)
•Near IR HD video output with automatic HD video recording of fire events
•Option: Improved speed of response for standard fires - (0.5s) for enclosed space protection, like spray
paint booths or printing presses.
•Data/Event logger –alarms, faults and other relevant events are logged to non-volatile memory
•Ethernet communication –in addition to the standard methods, such as 4-20mA and Modbus
•Built-in-Test (BIT) –Automatic and manual internal self-test of window cleanliness and the overall
operation of the detector
•Window heater to avoid condensation and icing
•Tilt mounting bracket for accurate detector positioning

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 4.1). During “Dirty Window” fault the detection sensitivity is
significantly reduced, while “Fault” refers to critical faults which totally prevent flame detection.

1.5.5 Flame Simulator
The FLS-IR3-H2-HD may be tested using the FLS-
FSIM-IR3-H2-KIT. The FlameSpec flame simulator
family provides a fast and convenient means of
periodically testing the detector and control system
end-to-end. Maintenance costs can be reduced as
the detectors can be tested in situ without needing a
hot work permit.
FlameSpec Flame Simulators emit IR radiation in a
special electromagnetic radiation pattern which
simulates a hydrogen fire to the detectors. The
simulators are lightweight, easy to use, with testing
distances of up to 23 ft. (7m) and capable of more
than 1000 activations between battery charging.
FlameSpec Flame Simulators are ATEX approved
for use in hazardous Zone 1, Zone 2, Zone 11, Zone
22 areas.
Each simulator kit contains a carrying case,
simulator, carrying strap, battery charger, user
manual, Allen key and a tool for removing the
simulator rear cover.

2Installation
This chapter does not attempt to cover all 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.
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 performance target, system configuration,
installation location and coverage considerations have been defined by the responsible
person.
To ensure optimal performance 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.
•Potential sources of false alarms that may be present (e.g., naked flames, hot process).
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 (See Figure 9 and Figure 10)

Environment
•Environmental conditions including but not limited to dust, snow or rain can reduce the
detectors sensitivity and require additional consideration.
Hot Work
•Arc welding should not be performed within 12 ft. (3.5m) 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.

Preparations for Installation
The installation must comply with national and 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 the authority having jurisdiction.
Prior to installation:
•Make sure that you have all the components and tools required to complete the
installation before starting. In cases where you cannot complete the installation in a
single session, secure and seal the detectors and conduits before leaving site
•Use color-coded conductors or suitable wire markings or labels for the wiring. You may
use 14 to 17 AWG (2.5mm2to 1.0mm2) multi-strand 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.
•Individually screen twisted pair cable is recommended for RS485 terminals.
•Use suitably rating wire for the application certification and temperatures.

•If the equipment is likely to come into contact with corrosive and/or other harsh
substances, consult with the relevant technical persons to take suitable precautions to
prevent the detector from being adversely affected, thus ensuring that the type of
protection is not compromised.
•Harsh substances: For example, acidic liquids, gases, or solvents that may attack the
windows, metals, seals or polymeric materials.
•Suitable precautions: For example, regular checks as part of routine inspections or
establishing from the material’s data sheet that it is resistant to specific chemicals.

Mounting the Tilt Mount
The tilt mount enables the detector to be rotated up to 45 degrees (horizontal/vertical) in all
directions. The following installation instructions show how to use it to support the detector from
below (the preferred method).
To install the tilt mount:
a) Mount the tilt mount base (Figure 11: Tilt Mount Base - Plate View) to a solid structure using
four suitable fixings through the four 7mm (0.28") diameter holes. Four captive screws with
spring washers are provided in the tilt mount.

Mounting the detector
Use the following steps to connect the detector to the tilt mount, referring to Figure 13:
a) Place the detector, with its cable/conduit entries pointing down, on the holding plate of the tilt
mount (item 2).
b) Secure the detector to the plate using the two hex screws and spring lock washers (items 3
and 4).
c) Loosen the locking screws (Items 5 and 6) in such a way that enables you to rotate the
detector.
d) Point the detector towards the detection area and make certain that the view of the area is
unobstructed.
e) Secure the detector in that position by tightening the locking screws (Items 5 and 6) on the tilt
mount. (Make sure the detector is pointing in the correct direction).
The detector is now correctly mounted, aligned and ready for electrical connection. Please refer
to section 2.7 for wiring instructions, and section 3 for a description of the detector’s configuration
settings.
