Product Overview
TM40/40UFI Rev. (Ai), February 2019 15
2Product Overview
The SharpEye 40/40UFI is a flame detector that utilizes improved IR3 technology
to provide state-of-the-art fire protection. The 40/40UFI uses patented digital
signal processing to analyze the spectral and dynamic characteristics of the
measured infrared radiation, to identify fire events with exceptional sensitivity
and extreme immunity to false alarms.
All 40/40 series detectors include a heated optical window for improved
performance in ice, snow, and condensation conditions.
Detection performance can be easily adapted to all environments, applications,
and requirements, by changing the detector’s configuration parameters.
Adjusting these parameters, as well as performing other maintenance and
monitoring tasks, is possible by means of RS-485-based Modbus communication
or HART communication (in models with 0–20mA output).
Warning:
The detector is not field-repairable due to the meticulous alignment
and calibration of the sensors and the respective circuits. Do not
attempt to modify or repair the internal circuits or change their
settings, as this will impair the system’s performance and void the
SPECTREX product warranty.
The SharpEye 40/40 detector is designed to operate as a stand-alone unit
directly connected to an alarm system or an automatic fire extinguishing system.
The detector can also be a part of a more complex system, where many detectors
and other devices are integrated through a common control unit.
2.1 Approvals
The detector enclosure is ATEX certified Exd flameproof with an integral,
segregated, rear, Exe terminal compartment (avoiding exposure of the sensors
and electronics to the surrounding environment). Hence the combined approval:
Ex II 2G D
Ex db eb op is IIC T4 Gb

2.4 Principles of Operation
This section describes the 40/40 principles of operation.
2.4.1 Hydrocarbon Fire Detection
The SharpEye 40/40UFI Detector is designed to detect flames in which carbon
dioxide (CO2) is produced in the combustion process. These include all
hydrocarbon flames, as well as other types of flames and burning materials such
as wood or alcohol.
The detector’s principle of operation is based on patented IR3 technology. This
technology identifies the unique spectral signature that hot CO2has in the
infrared (IR), namely a peak of intensity at wavelengths of 4.2–4.7µm.
The original IR3 technique (such as implemented in the SharpEye 20/20I Flame
Detector) utilizes 3 infrared sensors, each sensitive to its own wavelength range.
The first sensor is sensitive to wavelengths within the emission peak of hot CO2.
The other 2 sensors are sensitive to wavelengths above and below this peak. In

Product Overview
TM40/40UFI Rev. (Ai), February 2019 19
the event of fire, the signal measured in the first sensor is significantly higher
than those measured in the other 2 sensors. In order to trigger a fire alarm,
these and other conditions must be met (for example, radiation is flickering in
frequencies typical of flames). The detector does not react when exposed to non-
fire radiation sources.
The SharpEye 40/40UFI also includes an additional IR sensor, sensitive to a
different band within the emission peak of hot CO2. This sensor’s signal is
compared to those of the other 3, thereby increasing sensitivity for some types of
flames, such as gas flames.
2.4.2 Heated Optics
The SharpEye 40/40 Flame Detector uses heated optics. The heater increases the
temperature of the optical surface by 5–8°F / ~3–5°C above the ambient
temperature to improve performance in ice, condensation, and snow conditions.
The heated optics can be set to one of the following:
•Not operated.
•On continuously.
•Automatic, per temperature change (default): you can define the start
temperature below which the window is heated. (The default is 41°F/5°C.)
This temperature can be defined from 32°F/0°C to 86°F/30°C. The heating
stops when the temperature is 27°F/15°C above the start temperature.
For more information, see Configuring Your Detector on page 41.
2.4.3 HART Protocol
The 40/40 Flame Detectors use the HART protocol.
HART Communication is a bi-directional industrial field communication protocol
used to communicate between intelligent field instruments and host systems.
HART is the global standard for smart process instrumentation and the majority
of smart field devices installed in plants worldwide are HART-enabled. HART is
available in wiring options 1, 2, and 3, see Table 1, page 17.
HART technology is easy to use and very reliable.
Through the HART connection, you are able to perform:
•Detector setup
•Detector troubleshooting
•Detector health and status
For more details, refer to the HART Manual TM777030.
2.4.4 RS-485 Modbus
For more advanced communications, the 40/40UFI detector has an RS-485
Modbus-compatible output that provides data communication from a network (up
to 247 detectors) to a host computer or universal controller for central
monitoring. This feature allows for reduced installation costs, easy maintenance,
and local or remote diagnostic tools.
