1INTRODUCTION
1.1 Overview
The SharpEye 40/40I is a flame detector that utilizes improved IR3 technology to provide
state-of-the-art fire protection. The 40/40I uses patented digital signal processing to
analyze the spectral and dynamic characteristics of the 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
icing, 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 and performing other maintenance and monitoring tasks, is possible by
means of RS485-based Modbus communication or HART communication (in models with
0-20mA output).
The detector enclosure is ATEX certified EExd flameproof with an integral, segregated,
rear, EExe terminal compartment (avoiding exposure of the sensors and electronics to
surrounding environment). Hence the combined approval EExde IIB + H2 T5 (75°C) or
T4 (85°C).
The SharpEye 40/40 detectors are 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.
1.2 Model and Types
The 40/40I is provided in various configurations depending on:
•Wiring options
•Temperature ranges
•Type of cable entries
•Housing type
•Required approval
The configuration detail is included in the product part number on the product label and
takes the form: 40/40I XXXXX, where XXXXX defines the model according to the above
requirements.
To modify the default or pre-ordered configuration and perform maintenance tasks, please
refer to the HART Protocol TM777030, the RS-485 Manual TM 777050 or TM777060.

Note: Wiring option 1 is default. The mA 'Sink' output can be altered to 'Source' type,
with a link between terminals 1 and 8. No other wiring options can be changed on site.
For example, product number 40/40I-321SC has the following options:
•Wiring Option: 3 (Power, Manual BIT, RS-485, 0-20mA (Source)
with HART Protocol, Fault Relay (N.O), Alarm Relay (N.O, N.C))
•Temperature Range: 2 (85°C)
•Cable Entry: 1 (M25)
•Housing : S (Stainless Steel)
•Approval: C (ATEX, IECEx)

1.4 Principles of Operation
1.4.1 Hydrocarbon Fire Detection
The SharpEye 40/40I 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 the intensity at wavelengths 4.2 to 4.7µ.
The original IR3 technique (such as implemented in the SharpEye 20/20I flame detector)
utilizes three 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 two sensorsare
sensitive to wavelengths above and below this peak. In the event of fire, the signal
measured in the first sensor is significantly higher than those measured in the other two
sensors. In order to issue a fire alarm, the detector requires that this occurs, as well as
other conditions (for example, radiation is flickering in frequencies typical of flames). If
exposed to non-fire radiation sources, the specific conditions required does not occur, and
the detector does not react.
The SharpEye 40/40I further includes an additional IR sensor, sensitive to a different band
within the emission peak of hot CO2. The signal of this sensor is compared to those of the
other three. This increases sensitivity for some types of flames. (For example, gas flames).
1.4.2 HeatedOptics
The SharpEye 40/40 Flame Detectors use 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 icing, condensation and snow conditions.
