1.1 Overview
The 40/40M Multi IR Flame Detector is specifically designed for detection of
hydrocarbon and hydrogen flames. It detects hydrocarbon-based fuel and
gas fires at long distances with the highest immunity to false alarms. The
40/40M can detect a gasoline pan fire at 215 ft/65m or a hydrogen flame at
100 ft/30m in less than 5 seconds.
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).
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
Ex tb op is IIIC T96°C Db
(–55°C ≤ Ta ≤ +75°C)
or
Ex II 2G D
Ex db eb op is IIC T4 Gb
Ex tb op is IIIC T106°C Db
(–55°C ≤ Ta ≤ +85°C)
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.

1.4 Principles of Operation
This section describes the 40/40M principles of operation and includes:
Fire Detection Principle, page 17
Heated Optics, page 17
HART Protocol, page 17
RS-485 Modbus, page 18
Product Certification, page 18

TM 40/40M, Rev (14) February 2017
Principles of Operation 17
1.4.1 Fire Detection Principle
The SharpEye 40/40M Detector is designed to detect hydrocarbon flames
that produce CO2in their combustion process and non-hydrocarbon flames
that produce mainly water vapor (H2O) from inorganic fuels, for example,
hydrogen, ammonia, hydrofluoric acid, hydrochloric acid and so on.
The detector's principle of operation is based on the patented spectral
analysis technology that identifies the IR spectral signature of fire products,
i.e. the hot CO2spectral emission band at wavelengths of 4.2–4.7µm and
the hot water (H2O) spectral emission band at wavelengths of 2.7–3.0µm.
Additional spectral bands (above and below these bands) are analyzed for
background interferences.
The spectral analysis incorporates several detection algorithms, according to
several types of fire events, taking into account simultaneous detection of
both CO2and H2O peaks, or only one of them, as well as flickering analysis
at frequencies typical to these flames. Only when all the parameters of the
spectral analysis and the flickering analysis meet the predetermined values,
is a fire condition identified and the fire alarm is issued.
When exposed to non-fire radiation sources, these parameters do not
identify a fire condition and the detector does not react.
1.4.2 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 45.
1.4.3 HART Protocol
The SharpEye 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 15).
HART technology is easy to use and very reliable.

Multi IR Hydrocarbon and Hydrogen Flame Detector User Guide
18 Principles of Operation
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 TM 777030.
1.4.4 RS-485 Modbus
For more advanced communications, the 40/40M 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.

ATEX, IECEx, page 18
FM, CSA, page 19
SIL-2 (TÜV), page 19
EN54-10, page 19
Inmetro (UL), page 19
TR CU/EAC, page 20

1.5.1 Detection Sensitivity
Detection sensitivity is the maximum distance at which the detector reliably
detects a specific size of fire and typical type of fuel (standard fire).
Standard Fire 1.5.1.1
Defined as a 1ft2/0.1m2n-heptane pan fire, with maximum wind speed of
6.5ft/sec / 2m/sec.
Sensitivity Ranges 1.5.1.2
The detector has 4 user-selectable sensitivity ranges. For each range there
are 2 response levels.
Warning (Pre-alarm)
Alarm
The detection distance for the Warning level, is approximately 10% higher
than for the Alarm distance.
