1.1 Overview

The 40/40R Single IR Flame Detector detects hydrocarbon-based fuel and gas fires using advanced flame tools.

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.

• RS-485 Modbus, page 5

• Product Certification, page 6

1.4.1 Fire Detection Principles of Operation

The Single IR flame detector provides early warning of flaming fires involving organic materials (hydrocarbon fuels and vapors). These fires emit strong IR radiation in the 4.4-micron spectral band where the CO combustion product of any organic substance) has a unique spectral peak.

This detector contains an advanced infrared sensor and optical filter that provides maximum sensitivity to the CO micron.

The detector is designed to withstand “harsh” environment conditions, for example; extreme temperatures, high humidity and vibrations.

4 Features and Benefits

TM 40/40R, Rev (4) November 2010

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 27.

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 2 and 3, see Table 1, page 3.

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.

1.4.4 RS-485 Modbus

For more advanced communications, the 40/40R 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.

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 two response levels:

• WARNING (Pre-alarm)

• ALARM

The detection distance, for the WARNING level, is approximately 10% higher than the ALARM distance.

The detection distance for the ALARM level is 50 ft. (15m) from a standard fire. For some typical ambient conditions the Zeta parameter as defined in NFPA 72 for the detector is 0.005 (1/meter).

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:

• The baseline fire refers to n-heptane 1ft 100% sensitivity.

• For fuel fire – standard pan fire size: 1 ft

• For gas flame - 20 inch (0.5m) high, 8 inch (0.2m) width plume fire.

• Maximum Response Time: 10 sec.

(0.1m2) and is defined as

1.5.6 Detector Status

The possible detector function statuses are listed in Table 6. A more detailed fault analysis can be seen via HART or RS485.

Table 6: Detector Status Status Description

Normal Normal operation. BIT Built-In-Test being performed. Warning Fire detected - changed to Warning (pre-alarm state). Alarm Fire detected - changed to Fire Alarm state. Latched Alarm

(Optional) BIT Fault

Fault

In each state, the detector activates different outputs, as specified in Table 7.

The alarm outputs remain latched on following detection of a fire that has already been extinguished.

A fault is detected during BIT sequence or other electric failure. The detector will continue to detect for fire.

A fault is detected when the power supply is too low or due to a software fault or electrical failure. The detector will NOT detect fire in this condition.

Notes:

The alarm outputs are activated while alarm conditions exist and will

stop approximately 5 seconds after the fire is no longer detected.

2 The Alarm state can be optionally latched via programmed function.

(Default is non-latching). The detector will remain in BIT Fault state until it has passed a

successful BIT.

12 Performance Considerations

TM 40/40R, Rev (4) November 2010

The Auxiliary Relay can be activated at the Warning level or Alarm level,

depending on programmed function.

5 The outputs depend on the wiring options.

1.5.6.1 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 15).

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:

• The Auxiliary Relay is available only in Models with suffix – 4XXXX and 5XXXX

• The 0-20mA is available only in Models with suffix – 1XXXX, 2XXXX, 3XXXX

1.5.7 Auxiliary Relay as End-of-Line Resistor

The Auxiliary Relay can be used as End-of-Line (EOL) resistance in Models with suffix-4XXXX, and 5XXXX only. In this case, the Auxiliary Relay is active as long as the detector is not in Fault state.

1.6 Internal Detector Tests

The detector performs two types of self tests:

• Continuous Feature Test, page 13

• Built-In-Test (BIT), page 14

1.6.1 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:

• 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

• Relays and heater operation

Internal Detector Tests 13

SharpEyeTM Single IR Flame Detector User Guide

• Processor Watch dog

• Software

• Memory

• Oscillator frequency

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.

14 Internal Detector Tests

TM 40/40R, Rev (4) November 2010

1.6.2.2 Automatic BIT

The detector automatically performs a BIT every 15 minutes. A successful BIT sequence does not activate any indicator.

The results of a successful and unsuccessful BIT are listed in Table 8 and Table 9.

SharpEyeTM Single IR Flame Detector User Guide

• EOL – No

• Heated Optics – Auto

• Temperature – 41°F (5°C)

2.8.1 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.

2.8.2 Address Set-up

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

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:



1 Verify that the detector is Normal Mode. 2 Initiate Manual BIT. The results of successful and unsuccessful manual

BITs are detailed in Table 10 and Table 11.

3.3.3 Testing with Fire Simulator Model 20/20-312

The Fire Simulator Model 20/20-312 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 Fire Simulator on page 55 for more information.

Important: If the detector is exposed to a fire 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.

Testing Procedures 33

HART Protocol

•

The HART protocol is a digital communication signal at a low level on top of the 0-20mA. This is a bidirectional field communication protocol used to 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 777030.

• 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.

Headed Optics

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 25). 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 24, 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

Using the 0-20mA Interface for Alerting on page 62, point 1 and in Using the Alarm Relay Contact for Alerting on page 62, point

function of the 40/40 Flame Detector (flame detection, function of the 0-20mA interface, relay functions) must be checked completely.

E.1.2.2 Usi ng the 0-20mA Interface for Alerting

1 The following parameters shall be set:

• AUTOMATIC BIT test = on

• Connected to 0-20mA Terminals

2 The following allowed output current must be supervised with an

accuracy of ± 5%:

) and the

• Normal State = 4mA

• Warning State = 16mA

• Alarm State = 20mA

The output current must be supervised regarding the over-and under run

of the 0-20mA.

E.1.2.3 Usi ng the Alarm Relay Contact for Alerting

The following parameters shall be set:

• AUTOMATIC BIT Test = on

• Connected to N.C contact of Alarm Relay Terminals

• Connected to Fault Relay Terminals

The relay contacts (“alarm” – and “faulty relay”) must be protected with

a fuse rated at 0.6 of the nominal specified relay contact current. The maximum contact rating that is allowed per SIL-2 is 30VDC.

3 4 It is to be considered that the contact of the Alarm Relay opens if there

is a fire alarm. During the forwarding and evaluation of the alarm it must be noted that

the relay contact opens. The alarm relay can be used as low demand only.

E.1.2.4 Other

The complete function of the flame detector (flame detection, function of

the 0-20mA interface, the relays) must be examined at least every six or twelve months (see The SharpEye 40/40RSafety Relevant Parameters on page 61, when the flame detector must be switched OFF and ON.

The window of the sensor must be examined at appropriate time

intervals for partial contamination. The HART and the RS 485/IrDA interfaces must not be used for the

transmission of the safety-related data.
