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 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 Exd flameproof with an integral,
segregated, rear, Exe terminal compartment (avoiding exposure of the
sensors and electronics to surrounding environment). Hence the combined
approval:

Features and Benefits
TM 40/40M, Rev (9) August 2015
1.4.1
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.
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 41°F
(5°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 31.
1.4.3
HART Protocol
The SharpEye40/40 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 HARTenabled. HART is available in wiring options 1, 2 and 3, see Table 1, page 3.
HART technology is easy to use and very reliable.

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).
1.5.1.1
Standard Fire
Defined as a 1ft2 / 0.1m2 n-heptane pan fire, with maximum wind speed of
6.5 ft./sec (2 m/sec).
1.5.1.2
Sensitivity Ranges
The detector has four user-selectable sensitivity ranges. For each range
there are two response levels.

WARNING (Pre-alarm)

ALARM
The detection distance, for the WARNING level, is approximately 10% higher
than the ALARM distance.
Alarm response times for a standard fire at a specified range are shown
Table 2.

Note: Zeta parameters may vary significantly with changes in temperature,
air pressure, humidity, visibility conditions, and so on.
1.5.1.3
Other Fuels
The detector reacts to other types of fire as follows:
8

The baseline fire refers to n-heptane 1ft2 (0.1m2) and is defined as
100% sensitivity.

For fuel fire – standard pan fire size: 1 ft2 (0.1 m2).

For gas flame - 30 inch (0.75m) high, 10 inch (0.25m) width plume fire.

Maximum Response Time: 10 sec.

Internal Detector Tests
The detector performs two types of self-tests:
1.6.1

Continuous Feature Test, page 16

Built-In-Test (BIT), page 17
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:
16

Input voltage level

All internal regulator voltage level

Voltage level status of sensor and sensor circuitry for noise or
disconnection in the electronic circuitry

0-20mA level output

Response to Fault Indication
If a failure is found, the detector indicates by:

Fault relay:

Opens in wiring option 1, 2, and 4

Closes in wiring option 3 and 5

0-20mA: indicates Fault (0mA or 2mA) in wiring option 1, 2, 3

LED – Yellow flashes (4 Hz)

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.

Rather, it emphasizes specific points of consideration and provides some
general rules for qualified personnel. Wherever applicable, special safety
precautions are stressed.
2.1
General Guidelines
To ensure optimal performance and an efficient installation, consider the
following guidelines:



Sensitivity: To determine the level of sensitivity, consider the following:

Size of fire at the required distance to be detected

Type of flammable materials
Wiring:

The wire gauge must be designed according to the distance from the
detector to the controller and the number of detectors on the same
power line. See Wiring Instructions on page 53.

To fully comply with EMC directive and protect against interference
caused by RFI and EMI, the cable to the detector must be shielded
and the detector must be grounded. The shield should be grounded
at the detector end.
Spacing and Location: The number of detectors and their locations in
the protected area are determined by:

Size of the protected area

Sensitivity of the detectors

Obstructed lines of sight

Cone of view of the detectors
General Guidelines
21
Multi IR Hydrocarbon and Hydrogen Flame Detector User Guide


Environment:

Dust, snow or rain can reduce the detectors sensitivity and require
more maintenance activities.

The presence of high intensity flickering IR sources may affect
sensitivity.
Aiming the Detector:

The detector should be aimed toward the center of the detection
zone and have a completely unobstructed view of the protected area.


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.
2.8.3
Address Set-up
The detector provides up to 247 addresses that can be changed with the
RS485 communication link or the HART protocol.

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 4 mA.
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 the detector when it is in a LATCHED ALARM state:

Do one of the following:

Disconnect power (Terminal Number 1 or Terminal Number 2).
or


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 Flame Simulator Model 20/20-313
The Flame 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 Flame Simulator on page 61 for more
information.
Important: If the detector is exposed to a flame simulator, the Alarm and
Accessory Relays and 0-20mA 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 Flame Simulator Test:
1
Power up the system and wait up to 60 seconds for the detector to turn
to a normal state. The Power LED turns on.

Optics
48
communicate between intelligent field instruments
and the host system. HART is available in wiring
options 2 and 3.
Through the HART protocol the detector can:
 Display set-up
 Reconfigure the set-up
 Display detector status and definition
 Perform detector diagnostics
 Troubleshoot
For more details refer to HART Manual TM777030.
Communication Network: The detector is equipped
with an RS-485 communication link that can be used
in installations with computerized controllers.
The communications protocol is Modbus compatible.
 This protocol is a standard and widely used.
 It enables continuous communication between a
standard Modbus controller (Master device) and a
serial Network of up to 247 detectors.
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 5-8°F
(3-5°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.

Calculation Formula
Use the following formula to calculate minimum wire gauge per wire length
between the power supply (controller) and the detector, considering the
number of detectors on the same power line, where:
L = Actual wire length between the detector and the power supply.
N = Number of detectors per loop.
R = Resistance of wire per 100 m (see Table 26).
V = Voltage drop on the wire.
Calculate the voltage drop on the wire as follows:
V = 2L x R x N x 0.2A
100
20+V = Minimum required voltage of the power supply
0.2A is the maximum power consumption of the detector
For example,
If N=1 (1 detector in loop)
L=1000m
Wire size = 1.5mm² (see Table 25, the resistance per 100m for 1.5mm² is
1.4Ω)
You calculate the voltage drop in the wire as follows:
2 x 1000 x 1.4Ω x 1 x 0.2A = 5.6V
100
The minimum voltage of the power supply should be 20V + 5.6V = 25.6V

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.
