2.2 Principles of Operation
2.2.1 Hydrocarbon Fire Detection
The triple IR flame detector detects all conceivable types of hydrocarbon
fires, i.e. any fire, which emits CO2.
2.2.2 Identifying the CO2 Peak
Features 3
The hydrocarbon fire is characterized by a typical radiation emission. The
CO2 peak emits intense radiation in the spectral band between 4.2 µ - 4.5 µ
and weaker radiation intensity outside this spectral band.
SharpEyeTM IR3 Flame Detector User Guide
2.2.3 Limitations of IR-IR Flame Detectors
CO2 in the atmosphere attenuates the radiation in this spectral band.
(Absorption and emission of radiation always occur in the same band.) As a
result, the greater the distance between the detector and the fire, the
weaker the intensity of the radiation reaching the detector (the CO2
attenuation increases). This phenomenon explains the limitations of the
existing IR-IR flame detectors in the market:
Detection distance is restricted to 33 ft. (10 m) only.
Their immunity to false alarm sources is limited.
2.2.4 Advantages of IR3 Technology
To overcome these limitations, Spectrex Inc. devised an innovative concept
of utilizing an additional detection channel. Three channels collect more data
from the environment, permitting more accurate analysis and better
performance.
After careful investigation, three channels were selected which, when
operating jointly, provide optimal fire detection characteristics:
Channel 1: 4.2 µ - 4.6 µ
Fire - the CO2 peak
Channel 2: 4.0 µ - 4.2 µ
Eliminates false alarms from high temperature sources.
Channel 3: 4.8 µ - 5.2 µ
Eliminates false alarms from flickering of background radiation.
Most IR sources, which create misleading IR alarm stimuli, including the
sun, incandescent and halogen lamps, electric arc discharges, electrical
heaters, etc., do not possess this unique spectral signature of fire.
The IR sensors of the detector respond only to flickering of radiation signals.
The signals are compared to a predetermined threshold. Processing of the
results from the three IR channels is performed by the board
microprocessor. The result is a much greater detection distance and a highly
increased ability to distinguish between fire and false alarms.
This sophisticated technology surpasses all other existing flame detection
techniques on the market today.
Note: This unique flame analysis capability (patent pending) has been
incorporated into the Triple-IR fire detector manufactured by Spectrex, Inc.
The result is a unique flame detector, which does not produce false alarms
and provides detection over greatly increased distances at the same time.

3.1 Detection Sensitivity
Detection sensitivity is the maximum distance at which the detector will
reliably detect a specific size of fire and typical type of fuel (standard fire).
3.1.1 Standard Fire:
A standard fire is defined as a 1 ft2 (0.1m2) gasoline pan fire with maximum
wind speed of 6.5 ft./sec (2m/sec).
3.1.2 Sensitivity Ranges:
The detector has four user selectable sensitivity ranges. For each range
there are two response levels.
WARNING (Pre-alarm)
ALARM
The detection distance, for the WARNING level, is approximately 10% higher
than the ALARM distance. Alarm response times for a standard fire at a
specified range are shown in Table 1.
Table 1: Alarm Response Time versus Range
For some typical ambient conditions the Zeta parameter, as defined in
NFPA 72 for the detector, is 0.005 (1/meter).
Note: Zeta parameters may vary significantly with changes in temperature,
air pressure, humidity, visibility conditions, etc.

4.3 Detector Mode Setup
4.3.1 Detector Setting
Refer to Detector Default Setup on page 18 for default factory settings.
The detector incorporates several functions that can be set by the customer
using Spectrex Host software, which is supplied for each detector shipment,
(refer to manual TM768050 for programming instructions). The Host
software enables you to change functions as described in Detector on
page 16.
4.3.2 Detector Functions
4.3.2.1 Sensitivity Ranges
The detector offers four (4) sensitivity settings. The settings refer to the
gasoline fire of 1 ft2 from 33 ft. (10 m) to 140 ft. (43m). Detection distances
for other fuels vary.
4.3.2.2 Alarm Delay
The detector is equipped with an Alarm Delay option, which provides
programmable time delays of 0 to 30 seconds with eight (8) fixed settings:
0 seconds
Anti-flare
3 seconds
5 seconds
10 seconds
15 seconds
20 seconds
30 seconds
When an Alarm (Detection) level condition is encountered, the detector
delays the execution of the Alarm output’s relay by the specified period of
time. The detector then evaluates the condition for 3 seconds. If the Alarm
level is still present, the Alarm outputs are activated. If this condition no
longer exists, the detector returns to its standby state. The Alarm delay
option affects the alarm relay and the 0-20 mA output. The LED indicates
warning level during the delay time only if the fire condition exists.
Anti-Flare
Anti-Flare mode is selected to prevent false alarm in locations where fast
flares may be present. The Time delay for fire alarm in this mode is from 2.5
to 15 seconds (mostly less than 10 seconds).

been taken into account.
➣ In this chapter…
6.1 Scope
The SharpEye Model 20/20MPI is a self-contained Optical Flame Detector
designed to operate as a standalone unit directly connected to alarm
systems or automatic fire extinguishing systems. The detector can be a part
of a more complex system where many detectors and other devices are
integrated through a common control unit. 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. Wherever applicable, special safety precautions are
stressed.
6.2 General Considerations
To ensure optimal performance and an efficient installation, the following
guidelines should be considered:
Sensitivity
To determine the level of sensitivity, the following issues should be
considered:
Size of fire at determined distance to be detected.
User and Maintenance ManualUser and Maintenance Manual 23
Type of flammable materials.
SharpEyeTM IR3 Flame Detector User Guide
Spacing and Location
The number of detectors and their locations in the protected area are
affected by:
Size of the protected area
Sensitivity of the detectors
Obstructed lines of sight
Cone of view of the detectors
Environment
Dust, snow or rain can reduce the detectors sensitivity and require
more maintenance activities.
The presence of high intensity flickering of IR sources may affect
sensitivity.
6.3 Preparations for Installation
