Product Overview

TM40/40U Rev. (Af), February 2019 15

2 Product Overview

There are 2 versions of the 40/40 Series UV Flame Detectors: Model 40/40U and model 40/40UB, which also includes a Built-in-Test (BIT) feature.

The 40/40UV Flame Detectors detect hydrocarbon-based fuels and gas fires, invisible hydrogen flames and fires from hydride, ammonia, saline, and other organic fires.

Note:

This type of detector should not be exposed to a UV radiation source, such as welding, sparks, or an electronic arc, as it will result in a false alarm.

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).

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.

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.

2.1 Approvals

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:

Product Overview

TM40/40U Rev. (Af), February 2019 19

2.4 Principles of Operation

This section describes the principles of operation for the 40/40U and UB.

2.4.1 Hydrocarbon Fire Detection

The Model 40/40U and UB 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 Flame Detector is a single spectrum optical detector sensitive to the UV radiation spectrum that is present in fires. The detector monitors the protected volume, by measuring the radiation intensity in it, within the frequency range of the electromagnetic spectrum, namely the Ultra-Violet (UV).

The detector senses one channel in which appropriate detection pulses are registered, and further analyzed for frequency, intensity and duration.

• Sensing Element

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.

• Detection Levels

Detection of radiation in the UV channel, with an intensity that exceeds the detector’s preset warning level results in a:

• Warning signal

• Alarm signal

2.4.2 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 43.

2.4.3 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.

Product Overview

20 SharpEye™ UV Flame Detectors User Guide

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).

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 TM777030.

2.4.4 RS-485 Modbus

For more advanced communications, the 40/40U and UB 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.

2.5 Performance Considerations

This section describes performance aspects of the 40/40U and UB.

2.5.1 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).

2.5.1.1 Standard Fire

Defined as a 1ft2/0.1m2 n-heptane pan fire, with maximum wind speed of

6.5ft/sec / 2m/sec.

2.5.1.2 Sensitivity Ranges

The detector has 2 response levels:

• Warning (Pre-alarm)

• Alarm

The detection distance for the alarm level is 50ft/15m from a standard fire.

The detection distance for the warning level is approximately 10% higher than for the alarm distance.

For some typical ambient conditions the Zeta parameter as defined in NFPA 72 for the detector is 0.005 (1/m).

Note:

Zeta parameters may vary significantly with changes in temperature, air pressure, humidity, visibility conditions, etc.

Product Overview

TM40/40U Rev. (Af), February 2019 23

2.5.1.3 Other Fuels

The detector reacts to other types of fire as follows:

• The baseline fire refers to n-heptane 1ft

/0.1m2 and is defined as 100%

sensitivity.

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

/0.1m2.

• For gas flame – 30”/0.75m high, 10”/0.25m width plume fire.

• Maximum Response Time: 10 sec.

The alarm outputs are activated while alarm conditions exist and will stop approximately 5

seconds after the fire is no longer detected.

The alarm state can be optionally latched via programmed function (default is non-latched).

The detector will remain in BIT Fault state until it has passed a successful BIT.

The auxiliary relay can be activated at the warning level or alarm level, depending on

programmed function.

Note:

The outputs depend on the wiring options.

2.5.6.1 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 31).

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.

Product Overview

TM40/40U Rev. (Af), February 2019 29

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, and 3XXXX

2.5.7 Auxiliary Relay as End-of-Line

The auxiliary relay can be used as End-of-Line in models with suffix – 4XXXX and 5XXXX only. In this case, the auxiliary relay is active as long as the detector is powered.

2.6 Internal Detector Tests

The detector performs 2 types of self-tests:

• Continuous Feature Test, page 29

• Built-In-Test (BIT), page 30

2.6.1 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 levels

• Voltage level status of sensor and sensor circuitry for noise or disconnection

in the electronic circuitry

• 0–20mA level output

• Relays and heater operation

• Processor watchdog

• Software

• Memory

• Oscillator frequency

Product Overview

30 SharpEye™ UV Flame Detectors User Guide

2.6.2 Response to Fault Indication

If a failure is found, the detector indicates by:

• Fault relay:

• Opens in wiring options 1, 2, and 4

• Closes in wiring options 3 and 5

• 0-20mA: indicates fault (0mA or 2mA) in wiring options 1, 2, and 3

• LED – yellow flashes (4Hz)

• 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.

2.6.3 Built-In-Test (BIT)

The detector’s Built-In-Test (BIT) also checks the following:

• Electronic 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.

2.6.3.1 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 detector’s status changes (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.

Product Overview

TM40/40U Rev. (Af), February 2019 31

2.6.3.2 Automatic BIT

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

All outputs of BIT results function as described in Table 9 and Table 10, and the BIT is automatically executed every 1 minute.

This sequence continues until a successful BIT occurs, when the detector resumes normal operation.

3.1.1 Sensitivity

• To determine the level of sensitivity, consider the following:

• Size of fire at the required distance to be detected

• Type of flammable materials

3.1.2 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 61.

• 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.

3.1.3 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

3.1.4 Environment

• Dust, snow, or rain can reduce the detector’s sensitivity and require more

maintenance activities.

• The presence of high intensity flickering IR sources may affect sensitivity.

Installing the Detector

34 SharpEye™ UV Flame Detectors User Guide

3.1.5 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.

• Whenever possible, the detector face should be tilted down at a 45º angle to

maximize coverage and prevent accumulation of dust and dirt.

• Do not start an installation unless all conceivable considerations regarding

Installing the Detector

44 SharpEye™ UV Flame Detectors User Guide

3.8.1 Alarm Delay

The detector is equipped with an alarm delay option, which provides programmable time delays with settings at:

• Anti-flare (default)

Note:

The anti-flare 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 2.5–15 seconds, and is usually less than 10 seconds.

• 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.

3.8.2 Address Setup

The detector provides up to 247 addresses that can be changed with the RS-485 communication link or the HART protocol.

3.8.3 Function Setup

Operating the Detector

TM40/40U Rev. (Af), February 2019 47

4 Operating the Detector

This chapter describes how to power up and test the detector. It also includes some very important safety checks that you should complete before operating the detector.

4.1 Powering Up

This section describes how to power up the detector. Follow these instructions carefully to obtain optimal performance from the detector over its lifecycle:

To turn on the detector:

1 Turn on the power. 2 Wait up to 60 seconds for the detector to finish the start-up procedure.

Powering up initiates the following sequence of events:

• The yellow LED flashes at 4Hz.

• BIT is executed.

If successful, the green LED flashes at 1Hz, the fault relay contacts close, and mA output is 4mA.

3 Enter Normal mode.

Caution:

The majority of detectors are used in the default non-latched alarm mode. Only perform a reset when the latched alarm option has been programmed.

To reset the detector when it is in a latched alarm state:

• Disconnect power (Terminal Number 1 or Terminal Number 2).

• Initiate a Manual BIT.

4.2 Safety Precautions

After powering-up, the detector requires almost no attention in order to function properly, but the following should be noted:

• 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 connected.

Operating the Detector

48 SharpEye™ UV Flame Detectors User Guide

• Do not open the electronic compartment. This part should be kept closed at

all times and only opened in the factory. Opening the electronic component side invalidates the warranty.

• You should only access the wiring compartment to wire or remove the

detector, or to access RS-485 terminals for maintenance.

• External devices, such as automatic extinguishing systems, must be

disconnected or disabled before carrying out any maintenance.

4.3 Testing Procedures

This section describes the proof testing procedure for proper operation of the detector. The detector can be tested using the Manual BIT or the SPECTREX Flame Simulator FS-1200.

The detector performs internal tests continuously and automatic BIT tests every 15 minutes. For more details refer to Built-In-Test (BIT) on page 30.

Operating the Detector

TM40/40U Rev. (Af), February 2019 49

4.3.1 Automatic BIT Test

Check that the indicators show normal conditions. See Powering Up on page 47.

4.3.2 Manual BIT Test

Caution:

If the function setup alarm BIT and/or auxiliary BIT are set to Yes (default is 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:

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

are detailed in Table 11 and

Table 12.

4.3.3 Testing with Flame Simulator Model FS-1200

The Flame Simulator Model FS-1200 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 Flame Simulator FS-1200 on page 69 for more information.

Caution:

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 and any external devices which may be activated during this process must be disconnected.

To perform a 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.

2 Aim the SPECTREX Flame Simulator Model FS- at the target point of the

detector (Figure 15), such that the radiation emitted by it is facing directly towards the detector. (See Flame Simulator FS-1200 on page 69).

3 Press the operation button once. After few seconds, a successful test shows

the results listed in Table 17. The detector is now ready for operation.

B.2 Calculation Formula

Wiring Instructions

62 SharpEye™ UV Flame Detectors User Guide

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 100m (see Table 23)

• 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)

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 Communication Network

TM40/40U Rev. (Af), February 2019 67

Appendix C: RS-485 Communication Network

C.1 RS-485 Overview

By using the RS-485 network capability of the UV detector and additional software, it is possible to connect up to 32 detectors in an addressable system with 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 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 for each detector individually.

For more details, contact SPECTREX.
