1. Scope
1.1 Product Overview
The SharpEye CCTV Model Flame Detector (20/20CTIN and 20/20CTIP) is a self-
contained, triple-spectrum, optical flame detector that incorporates a video color
camera. The detector's IR sensors and spectral band pass filters have been
selected to ensure the greatest degree of spectral matching to the radiant energy
emissions of fire and the lowest degree of matching to non-fire stimuli.
The color video camera enables the user to investigate the monitored area, to
identify the fire's source and location, and help select the best response to the
situation (activation of fire suppression means).
Configuration can be made to issue a live color video picture signal at all times, on
request or only when a fire is detected. Therefore, the detector is also useful for
standard CCTV purposes.
The front side of the detector is sealed to keep the electronic and sensor chamber
dry for longer life. The programmable functions are available through a RS 485
port used with a standard PC or by a Pocket PC and software supplied by
Spectrex.
The video signal output of the CCTV Model Flame Detector can be either NTSC or
PAL.
Refer to Manual TM 784050 for instructions to use the HOST software and to
change the required Functions.

2.1 Principles Of Operation
2.1.1 Hydrocarbon fire detection
The triple IR flame detector detects all conceivable types of hydrocarbon fires, i.e.
any fire, which emits CO2.
2.1.2 Identifying the CO2peak
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.
2.1.3 The limitations of IR-IR flame detectors
CO2in 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 CO2attenuation increases). This phenomenon
explains the limitations of the existing IR-IR flame detectors in the market:
• Detection distance is restricted to 33ft (10m) only.
• Their immunity to false alarm sources is limited.
2.1.4 The advantages of IR3 technology
To overcome these limitations, Spectrex Inc. revised an innovative concept of
utilizing an additional detection channel. Three channels collect more data from
the environment, permitting more accurate analysis and better performance.

Spectrex Inc. - SharpEyeTM CCTV Model Flame Detector Manual – TM 788100, Rev. A January 2005
4
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 CO2peak
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.
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 at the same time detection over greatly increased distances.

2.1.5 Video Picture
The color video camera enables the user to investigate the monitored area, to
identify the fire source and location, to help select the best response to the
situation (activation of fire suppression means). Configuration can be made to
issue a live color video picture signal at all times, on request, or only when a fire is
detected; therefore, the detector is also useful for standard CCTV purposes.

3. Performance
3.1 Detection Sensitivity
A. Flame
Detection sensitivity is the maximum distance at which the detector will reliably
detect a specific size of fire & typical type of fuel (standard fire).
Standard Fire:
A 1ft x 1ft (0.3m x 0.3m) Gasoline pan fire with max. wind speed of 6.5 ft/sec
(2 m/sec).
Sensitivity Ranges:
The detector has four user selectable sensitivity ranges. For each range there are
two response levels.
1. WARNING (Pre-alarm)
2. ALARM
The detection distance, for the WARNING level, is approximately 10% longer than
the ALARM distance. Alarm response times for a “standard fire” at a specified
range are shown hereunder.
Table 1: Alarm Response Time Versus Range
Sensitivity 1 2 3 4
Range – ft (m) 50 (15) 100 (30) 150 (45) 200 (60)
Response Time (sec) 3 5 8 10
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 temp, air pressure,
humidity, visibility conditions, etc.

Other fuels
The detector will react to other types of fires as follows:
Pan Fire Size: 1ft x 1ft (0.3m x 0.3m)
Maximum Wind Speed: 6.5 ft/sec (2 m/sec)
Maximum Response Time: 10 sec

4.2 Output Signals
The detector controls the following outputs:
• Alarm relay
• Accessory relay
• Fault relay
• 4-20mA current output
• RS-485 communication
The detector can be in one of the following states.
Normal: The detector is functioning normally.
BIT: The detector performs a Built-In-Test.
Warning: Fire detected - changed to warning – pre-alarm state.
Alarm: Fire detected - changed to fire alarm state.
Latched Alarm
(Optional) The alarm outputs are latched due to the detection of a fire that
has already been extinguished.
Fault: A fault is detected during a BIT sequence or the power supply is
too low. In each state the detector will activate different outputs
as specified in table 6.

4.2.1 Optional latching
The detector includes an optional latched alarm output capability, which operates
according to the programmable function. Upon the detection of a fire, the detection
signal is latched until manually reset (disconnecting the power supply or
performing a manual BIT).
4.2.2 Built-In-Test (BIT)
Successful Manual BIT will activate the following outputs according to
programmable function. Table 7: Built-in Test
ALARM BIT AT YES The ALARM relay will be activated for 3 seconds.
The 4-20mA output will provide 15 mA for 3 seconds.
Accessory BIT AT YES The camera will be activated for 3 seconds.
The 4-20mA will provide 10 mA for 3 seconds.
4.2.3 CCTV Output
The video output is a standard port with two options:
a. Detector model No. 20/20 CTIN is a NTSC version
b. Detector model No. 20/20 CTIP is a PAL version
The video output can be activated continuously or only when a fire is detected,
according to programmable function. See Table 8
