1Introduction
The FlameSpec-IR3 (FLS-IR3) will detect fires and explosions extremely quickly allowing
preventative action to be initiated rapidly to help minimize the consequences.
•Detection within 40 milliseconds of fireballs or explosions
•Standard fire is detected within 1.5s from 100 ft. (30m), 3.7s from 230 ft. (70m) and 7.1s
from 262 ft. (80m).
The FlameSpec-IR3 flame detector provides ultra-fast response, high performance and reliable detection
of all types of hydrocarbon fires (visible and non-visible). The detector responds to slow growing fires as
well as fast growing fire using improved Triple IR (IR3) technology. The detector operates in all weather
and light conditions with highest immunity to false alarms. The integral event recording in addition to
the proven superior capabilities of Triple IR (IR3) flame detection provide you with a very powerful
safety tool to protect personnel, plant and process.
The detector is certified for use in hazardous area locations; it may also be used in other areas not
classified as hazardous. The two cable/conduit entries either side of the lower part of the detector
housing are for connecting power and outputs to associated signaling equipment.
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.
1.1 Features
•Extreme sensitivity - up to 260ft (80m) for a 1ft2(0.1m2) n-heptane pan fire.
•Ultra-fast detection mode - detection within 40 milliseconds for fireballs or explosions.
•Option: Improved false alarm immunity in high CO2 applications, like aircraft hangars or helidecks.
•Option: Improved speed of response - (0.5s) for enclosed spare protection, like automotive applications
in compliance with NFPA 33 or printing presses and conveyors.
•Built-in-Test (BIT) - Automatic and manual self-test of window cleanliness and detector operation.
•Window heater to avoid condensation and icing.
•Tilt mounting bracket for accurate detector positioning.

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 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,

2Installation
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 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.
