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.
The 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.

Fire Detection Principle
The SharpEye 40/40M detector is designed to detect hydrocarbon flames that produce
CO2 in 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.
4
Features and Benefits
TM 40/40M, Rev. (1) September 2008
The detector's principle of operation is based on the patented spectral
analysis technology that identifies the IR spectral signature of fire products, namely the
hot CO2 spectral emission band at 4.2-4.7 microns and the hot water (H2O) spectral
emission band at 2.7-3.0 microns. 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 CO2 and 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 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.
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 68°F
(20°C).) This temperature can be defined between 32°F (0°C) to 122°F
(50°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 29.
1.4.3
HART Protocol
The SharpEye 40/40 Flame Detector uses 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 technology is easy to use and very reliable.
Through the HART connection, you are able to perform:

Detector set-up

Detector troubleshooting

Detector health and status
For more details, refer to the HART Manual TM 777030.

The outputs depend on the wiring options.
Optional Latching
Alarms are set as non-latching by default. However, the detector includes a
latched alarm output capability, which operates according to the
programmed function.
If selected, upon detection of a fire, the detection signal is latched until a
manual reset is performed (disconnecting the power supply or performing a
manual BIT (see Manual BIT on page 16).
Latching affects the Alarm Relay, 0-20mA output, the Alarm LED (the
Auxiliary Relay will be latched only when the programmable function
Auxiliary Relay is set to YES.
Notes:

Internal Detector Tests
The detector performs two types of self tests:
1.6.1

Continuous Feature Test, page 14

Built-In-Test (BIT), page 15
Continuous Feature Test
During normal operation, the detector tests itself continuously and indicates
a fault if a failure is found. This type of test complies with SIL-2
requirements.
The detector continuously tests:
14

Input voltage level

All internal regulator voltage level

Voltage level status of sensor and sensor circuitry for noise or
disconnection in the electronic circuitry

Correcting the Fault
The fault indications remain until the detector‟s power is removed. The fault
indications return if the fault is still found when power is restored.
1.6.2
Built-In-Test (BIT)
The detector‟s Built-In-Test (BIT) also checks the following:

Electronics circuitry

Sensors

Window cleanliness
The detector can be set to perform the BIT in the following modes:

Automatically and manually

Manually only
Note: In Manual BIT, the outputs may also be tested and Control System
„inhibit‟ should be applied if this could initiate other systems.
1.6.2.1
How the BIT Operates

The detector's status remains unchanged if the result of a BIT is the
same as the current status (NORMAL or BIT Fault)

the detectors‟ status is changed (from Normal to BIT Fault or vice versa)
if the BIT differs from the current status
Note: In „BIT Fault‟ status the detector can continue to detect a fire.

Alarm Delay
The detector is equipped with an Alarm Delay option, which provides
programmable time delays with settings at:

Antiflare* (default)
*The Antiflare mode is selected to prevent false alarms in locations
where fast flares may be present. The Time Delay for fire alarms in this
mode ranges from 2.5 to 15 seconds (usually, less than 10 seconds).
Other delays settings are available:
0, 3, 5, 10, 15, 20 or 30 seconds
When an Alarm (Detection) level condition occurs, the detector delays the
execution of the Alarm outputs by the specified period of time. The detector
then evaluates the condition for 3 seconds. If the Alarm level is still present,
the Alarm outputs are activated. If this condition no longer exists, the
detector returns to its standby state.
The Alarm delay option affects the output relays and the 0-20mA. The LEDs
and outputs indicate warning levels during the delay time only if the fire
condition exists.

This chapter describes how to power up and test the detector. It also
includes some very important safety checks that you should make before
operating the detector.
3.1
Powering Up
This section describes how to power up the detector. Follow these
instructions carefully to obtain optimal performance from the detector over
its life cycle:
➣ To power up the detector:
1
Turn on the power.
2
Wait approximately 60 seconds for the detector to finish the start-up
procedure.
Applying power initiates the following sequence of events:

The yellow LED flashes at 4 Hz.

BIT is executed.
If successful, the green LED flashes at 1 Hz and the FAULT relay contacts
close, mA output is 5mA.
3
Enter to Normal mode.
Note: The majority of detectors are used in the default non-latching alarm
mode. Only perform a Reset when the Latching alarm option has been
programmed.
➣ To reset a detector when in it is in a LATCHED ALARM state:

Do one of the following:

Disconnect power (Terminal Number 1 or Terminal Number 2).
or


3.2
Safety Precautions
After powering-up, the detector requires almost no attention in order to
function properly, but the following should be noted:
3.2.1

Follow the instructions in this guide and refer to the drawings and
specifications.

Do not expose the detector to radiation of any kind unless required for
testing purposes.

Do not open the detector housing, while power is applied.


Automatic BIT Test
Check that the indicators show normal conditions. See Powering Up on
page 33.
3.3.2
Manual BIT Test
Important: If the function setup Alarm BIT and/or Auxiliary BIT are set
to Yes (default No), the Alarm, Auxiliary Relay and 0-20mA outputs are
activated during a Manual BIT. Therefore, automatic extinguishing systems
or any external devices that may be activated during BIT must be
disconnected.
➣ To perform a Manual BIT:
3.3.3
1
Verify that the detector is Normal Mode.
2
Initiate Manual BIT. The results of successful and unsuccessful manual
BITs are detailed in Table 12 and Table 13.
Testing with Fire Simulator Model 20/20-313
The Fire Simulator Model 20/20-313 can be used to simulate exposure of
the detector to a real fire condition. The detector is exposed to radiation at
the required detection level. As a result, the detector will generate a Fire
Alarm signal. See Long Range Multi IR Fire Simulator on page 59 for more
information.
Important: If the detector is exposed to a fire simulator, the Alarm
and Accessory Relays and 4-20mA are activated during the
simulation. Therefore, automatic extinguishing systems or any
external devices, which may be activated during this process, must
be disconnected.
➣ To perform Fire Simulator Test:
1
36
Power up the system and wait up to 60 seconds for the detector to turn
to a normal state. The Power LED turns on.

Headed Optics
A.2
The front window can be heated to improve performance
in icing, condensation and snow conditions. The heater
increases the temperature of the optical surface by
5°F - 8°F (3°C - 5°C) above the ambient temperature.
The heated optics can be configured in three ways:

Off: The optics are not heated

On: The optics are heated continuously

Auto: Operated only when the change of
temperature requires the heating. (default)
In Auto mode the start heating temperature can be
defined between 32°F - 122°F (0°C - 50°C). The
detector stops heating the window when the
temperature is 27°F (15°C) above the start
temperature.

RS-485 Overview
By using the RS-485 network capability of the Multi IR detector and
additional software, it is possible to connect up to 32 detectors in an
addressable system with four (4) wires only (2 for power and 2 for
communication). Using repeaters, the number of detectors can be much
larger (32 detectors for each repeater) up to 247 on the same four (4)
wires. When using the RS-485 network, it is possible to read each detector
status (FAULT, WARNING, and ALARM) and to initiate a BIT to each detector
individually.
For more details, consult Spectrex.

This appendix describes the accessories that can help you maximize fire
detection with the SharpEye Multi IR flame detector:
D.1
Long Range Multi IR Fire Simulator
The SharpEye Multi IR Long Range Fire Simulator 20/20-313 is designed
specifically for use with SharpEye flame detectors. The Fire Simulator emits
IR radiation in a unique sequential pattern corresponding to and
recognizable by the detector as fire. This allows the detectors to be tested
under simulated fire conditions without the associated risks of an open
flame.
