Product Overview
TM40/40UFL Rev. (Al), February 2019 15
2Product Overview
Model 40/40UFL provides a combination of UV and IR sensors, where the IR
sensor operates at a wavelength of 2.5–3.0µm. It can detect hydrocarbon-based
fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic
fires with ultrafast ability to detect fire or an explosion in less than 20msec.
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.
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 T5 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.

2.3 Principles of Operation
This section describes the 40/40UFL principles of operation.
The Model 40/40UFL Flame Detector is an electronic device designed to sense the
occurrence of fire and flames and subsequently activate an alarm or an
extinguishing system directly or through a control circuit.
The UV/IR Radiation Flame Detector is a dual spectrum optical detector sensitive
to 2 separate ranges of the radiation spectrum, both of which are present in fires.
The detector monitors the protected volume by measuring the radiation intensity
in it, within 2 frequency ranges of the electromagnetic spectrum; namely the
Ultra-Violet (UV) and the Infra-Red (IR).
The detector integrates 2 dependent channels in which appropriate detection
pulses are registered and further analyzed for frequency, intensity, and duration.
2.3.1 Sensing Elements
The IR sensor in Models 40/40UFL is sensitive to radiation over the range of 2.5–
3.0 microns where the H2emission has a unique spectral peak that enables
detection of hydrocarbon fires, gas fires, hydroxyl, and hydrogen fires, as well as
metal and inorganic fires.
The UV sensor is sensitive to radiation over the range of 0.185–0.260µm. The UV
Channel incorporates a special logic circuit that eliminates false alarms caused by
solar radiation and other non-fire UV sources. Furthermore, the UV channel’s
sensitivity is stabilized over the working temperature range.

www.acornfiresecurity.com

Product Overview
TM40/40UFL Rev. (Al), February 2019 19
2.3.2 Detection Levels
Simultaneous detection of radiation in both the UV and the IR channels, with an
intensity that exceeds the detector’s preset Warning level results in a Warning
signal.
Simultaneous detection of radiation in both the UV and the IR channels, with an
intensity that exceeds the detector’s preset Alarm level results in an Alarm signal.
Simultaneous detection of radiation in both the UV and the IR channels, with an
intensity that exceeds the detector’s preset Flash-Fire Detection level results in
an immediate Alarm signal.
Since the preset dual range and level of radiation, as well as the flickering
pattern, are characteristics of real fire, all other radiation sources apart from
actual fire are not detected, thus avoiding false alarms.
2.3.3 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 between 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 43.
2.3.4 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 on 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 TM 777030.

2.3.5 RS-485 Modbus
For more advanced communications, the 40/40UFL 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.
2.3.6 Product Certification
The 40/40UFL Flame Detectors have the following certifications:
•ATEX, IECEx, page 21
•FM, page 21
•SIL-2 (TÜV) , page 21
•EN54-10, page 21
•Inmetro (UL), page 22
