For Your Safety

Strictly follow the Instructions for Use

Any use of the device requires full understanding and strict observation of these instructions. The device is only to be

used for the purposes speciﬁ ed herein. This manual should be carefully read by any individuals who have or will have

responsibility for using or maintaining this product.

Maintenance

The Dräger Flame Detector 5000 must be inspected and serviced at regular intervals and a record kept. Repair and

general over-haul of the device may only be carried out by trained service personnel. We recommend that a service

contract be obtained with Dräger Safety UK Ltd and that all repairs also be carried out by them.

Under no circumstances should the detector housing be opened in a hazardous area. Detectors contain no user-

serviceable parts and should never be opened, other than for access to the terminal compartment. Under no

circumstances should any components be substituted. Failure to comply with this requirement may invalidate the

hazardous area certiﬁ cation or disturb the critical parameters of the Dräger Flame Detector 5000 resulting in damage

to the device or failure to detect ﬁ res. Observe the chapter ‘Maintenance’.

Use in areas subject to explosion hazards

The Dräger Flame Detector 5000 is certiﬁ ed for and intended for use in potentially hazardous areas. Equipment and

components which are used in explosion-hazard areas and which have been inspected and approved in accordance

with international or European explosion-protection regulations may be used only under the speciﬁ ed conditions. The

equipment or components may not be modiﬁ ed in any manner. Do not drill holes in any housing, as this will invalidate

the explosion protection.

Check that the materials used in the construction of this detector are compatible with the environment in which they

will operate, and that they will not be aﬀ ected by any anticipated contaminants. The detector should not be used in an

oxygen enriched atmosphere.

The purpose of the Dräger Flame Detector 5000 is to detect a ﬂ ame or ﬁ re. It may be installed in areas that contain

potentially explosive atmospheres, thus it is vital for your safety and that of others that its functions are understood and

that every aspect of installation, commissioning and maintenance are carried out correctly.

This manual is intended to inform you of all aspects of the Dräger Flame Detector 5000. However, if you are in any

doubt about any part of these instructions, any function of the equipment, or any operating procedure, please contact

Dräger Safety or your local distributor.

Safety Symbols used in this Manual

While reading this Manual, you will come across a number of warnings concerning some of the risks and dangers you

may face while using the device. These warnings contain “signal” words that will alert you to the degree of hazard you

may encounter. These words, and the hazard they describe, are as follows:

DANGER

Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION

Indicates a potentially hazardous situation which, if not avoided, could result in physical injury.

NOTICE

Indicates a potentially hazardous situation which, if not avoided, could result in damage to the product.

Intended Use

Dräger Flame Detector 5000

For use in an area which may contain potentially explosive atmostphere. Used to monitor and trigger the necessary

control actions upon the detection of ﬁ re or ﬂ ame in a given environment

Understanding t he System

Principle of Operation

The Dräger Flame Detector 5000 can operate ‘stand alone’ or can be integrated with an approved control system.

Detectors are typically located throughout the installation in order to achieve speciﬁ c detection coverage and ensure

that site performance requirements are met. All detectors are capable of providing live colour video images and ﬁ re

alarm/fault signalling to the control equipment. Each detector incorporates within a single unit an imaging device,

digital signal processing hardware, and ﬁ rmware algorithms to process live video images and recognise ﬂ ame

features. The detectors are capable of operating independently: external control equipment is not required for normal

functions. However, if an external controller is installed then certain additional features become available, such as

remote conﬁ guration and ﬁ rmware management. A remote operator can interrogate the detector and, during an alarm

situation, visually verify the hazard. Each detector can be individually conﬁ gured to operate seperately as a Flame

detector only, or Video Surveillance camera, or as a combined unit.

Detector Overview

The detector unit is comprised of two primary components, the detector enclosure, and the detector assembly. The

detector assembly should not be disassembled or tampered with in any way. The detector is shipped pre-assembled

and comes complete with all parts required for installation, including the bracket but excluding the client mounting

support, glands and cabling.

Optical Test

The camera implements an optical check for faulty or contaminated optics. The check measures the contrast in images

captured from the video sensor. If the contrast falls below a certain level, the detector will signal an optical fault. Optical

testing in the Visual Flame Detector can also be veriﬁ ed manually using the Dräger FS-5000. Another manual method

is simply to view the video from the detector, if the video-out is connected.

Detector Sensitivity

The Dräger Flame Detector 5000’s response to a ﬁ re depends on the fuel source and how it is released, ﬁ re size and

distance, orientation to the detector and local ambient conditions. The typical parameters can be made available by

contacting Dräger Safety UK Ltd.

Explosion-Protection Approval

The explosion-protection approvals are valid fo use of the device in gas/vapour-air mixture of combustible gases and

vapours under atmospheric conditions. The explosion-protection approvals are not valid for use in oxygen eriched

atmostpheres. In the case of unauthorised opening of the enclosure, the explosion-protection approval is void.

Intended Use

WARNING

Do not open the enclosure in the presence of an explosive atmostphere.

WARNING

All permits and proper site procedure and practises must be followed and the equipment must be isolated from the power supply before opening the enclosure in the field.

Field of View

The sensor can detect ﬁ res of 0.1m2 or greater, at 44m within a 90° horizontal ﬁ eld of view. The detector will only

respond to visible ﬂ ames within the ﬁ eld of view. Hence the detector will not to certain common sources of false alarms

such as reﬂ ected ﬂ are radiation. This also reduces the likelihood of cross-propagation of alarms caused by ﬁ res or

combustion products of ﬁ res burning out with the ﬁ eld of view.

The detectors should be aligned to view the intended hazard taking into account any obstruction and congestion.

Software analysis of the actual detector coverage may be required to ensure adequate coverage of the hazards. This

analysis can also be used to optimise the number of detectors and the loop conﬁ guration.

Visual Flame Detector does not have a traditional cone of vision like other IR ﬂ ame detector’s. The detector’s ﬁ eld of

view is a rectangular pyramidal shape and represents a radial projection of the detector’s rectangular sensing element.

The illustrations below show the Field of View and range for a ﬁ re of 0.1m2.

Installation of the Dräger Flame Detector 5000

In considering the application of the Dräger Flame Detector 5000 it is important to know of any conditions that may

prevent the detector from responding. The detector provides reliable response to visible ﬂ ames within its ﬁ eld of view,

and insensitivity to common false alarm sources.

Solid obstructions or a direct view of intense light sources may interfere with the detector sensitivity. Scaﬀ olding or

tarpaulins in the detector’s ﬁ eld of view may reduce coverage. Contamination of the detector window may result in a

reduction in sensitivity.

The detector provides a live colour video image for surveillance of the protected area. As with conventional video

cameras the detector should not face directly towards the sun or a brightly lit scene. In such conditions the detector’s

automatic exposure control would darken the image in order to avoid overexposure; the resulting picture may be too

dark for surveillance purposes. To obtain the best possible picture the detector should be facing away from the sun.

In the case of an oﬀ shore vessel or platform, the detector should ideally be placed facing inwards towards the plant

and with minimal view of the horizon.

The detector has a horizontal ﬁ eld of view of 90° and a vertical ﬁ eld of view of 65°. The location and orientation of the

detector in relation to the protected area determines the actual footprint. Achieving the desired coverage depends on

congestion within the protected space, the location of the detector(s) and the distance of the detector from the hazard.

It may be necessary to install more than one detector within an area in order to achieve adequate coverage.

The detector sensitivity, expressed as ﬁ re size at a distance, is determined visually by the apparent size of the ﬁ re. This

is a function of the fuel source, how it is released and distance from the detector to the ﬁ re. The detector response

time is relatively independent of fuel type and/or distance.

In common with other forms of ﬂ ame detection, the detector’s sensitivity is reduced and potentially blinded by dense

obscurants such as smoke, fog and other airborne particulates. The detector is insensitive to arc welding, however

should not be conducted within 1m of the detector.

Mechanical Install.

Detector Enclosure

The Draeger Flame Detector 5000’s electronics are housed in an enclosure certiﬁ ed for use in a hazardous areas. The

enclosure comprises of:

Front enclosure cover (including the faceplate window)•

Rear enclosure cover.•

Enclosure body (with certiﬁ cation label). •

Mounting bracket. •

The mounting bracket allows the detector’s vertical orientation to be adjusted from 0-45°, and allows a horizontal

rotation of ±45 °.

Installation of the Dräger Flame Detector 5000

Detector Enclosure with Bracket

Sighting requirements

Observe the following:

Ensure the mounting position is free from vibration or movement•

Prevent accidental knocking or forcing out of alignment •

Where snow or ice build-up is likely, the heater should be enabled•

To ensure the best possible video image the detector should be facing away from the sun•

Isolate as far as possible from local electrical interference sources•

Ensure suﬃ cient detection to achieve adequate coverage for all likely hazards•

Minimise exposure to contamination of the detector face plate•

Ensure ease of maintenance access to detector (i.e. direct, ladder or scaﬀ old access)•

All these issues are of crucial importance to a successful installation, and they should be given great attention during

the detailed design, construction, and commissioning phases of the work.

WARNING

Do not drill any holes in the housing as t his will invalidate t he explosion protection.

WARNING

Do not open the enclosure in the presence of an explosive atmosphere.

Installation of the Dräger Flame Detector 5000

Exposure to Flare Radiation

Flame detectors are frequently used where hydrocarbon ﬁ re hazards are expected; these are quite often processing

plants where a ﬂ are stack is in use nearby. The detector should not have a direct view of the ﬂ are.

Flexibility of mounting location

The detector requires a clear unobstructed view of the potential hazard. In order to avoid local obstructions, such

as pipe-work and cable trays, a 2m helix should be provided in the detector cable to allow local repositioning of the

detector.

Mounting Arrangements

Firm, vibration free mountings are essential for the operation of optical systems and the detector should, wherever

possible, be ﬁ xed to rigid mountings.

Thermal Disruption

Thermal convection plumes and exhaust gas plumes generally exhibit a visual ‘mirage’ eﬀ ect. In most cases this does

not aﬀ ect detector operation or sensitivity. The detector does not respond to black body radiation near the exhaust.

Optical Contamination

There are many sources of contamination such as oil, water (deluge water, rain and sea-spray), snow, ice, and internal

misting. The design of the detector incorporates an internal heater in order to resist condensation and ice build-up.

Excessive contamination of the detector faceplate may result in an increased maintenance requirement and potentially

reduce the detector’s sensitivity.

Where detectors are mounted at low level, care should be taken to avoid contamination (such as water and oil) from

equipment above the detector. Care should be taken in sighting the detector to minimise the likelihood of such

contamination.

Fog, smoke and other similar airborne contaminants aﬀ ect the detector’s sensitivity by reducing the detector’s range.

Enclosed Areas

In enclosed areas, if dense smoke is expected to accumulate at the onset of the ﬁ re, the detectors should be mounted

1-2m below the ceiling level.

The mounting bracket

The detector mounting bracket is designed to allow the detector to be mounted from a horizontal plane. The bracket

supplied with the detector and the dimensions of the ﬁ xing holes are illustrated on the following page.

Electrical Install

Detector Electronics Subassembly

The ﬁ eld wiring is accessed by removing the rear enclosure cover and all terminations are accessible without the need

to access the electronics module mounted in the front portion of the enclosure.

WARNING

For European (ATEX) installations, IEC/EN60079-14 ‘Electrical Installations in Hazardous Areas’ and ICE/EN60079-17 ‘Inspection and Maintenance in Hazardous Areas’ should be strictly observed.

WARNING

For installations all Local and International regulations should be strictly observed.

Earthing & Screening Requirements

It is important to ensure that the system is correctly connected to earth. Incorrect or poor earthing can adversely aﬀ ect

system operation and may result in intermittent RS485 communications and poor video image quality.

WARNING

The equipment must be properly earthed to protect against electrical shock and to minimise electrical interference.

The system 0V should be connected to a clean earth at only one point; generally this should be at the panel power

supply (or 0V bus bar). Where PC equipment is connected to the RS485 and Video signals, care should be taken

to ensure that the PC’s and Panel’s power supply are at the same ground potential. Even small diﬀ erences in earth

potentials can cause an earth fault current to ﬂ ow resulting in video corruption. Where this is not possible either the

PC’s local supply should be isolated and the PC’s connected to the ‘system clean earth’, or alternatively, the Video and

RS485 signals should be isolated. The Dräger Safety UK Ltd twisted pair to BNC video converter (VTP4) and RS232

to RS485 converter (RS2485IF) can be used so long as the maximum potential diﬀ erence between each earth does

not exceed ±5V, as identiﬁ ed below.

In distributed systems with multiple DC-DC power supply units all 0V supplies must be connected together to a

common clean earth. Where this is not possible each system can either be connected to a local clean earth so long as

the maximum potential diﬀ erence between each earth does not exceed +4 to -1Vdc, alternatively the Video and RS485

signals can be galvanically isolated from the central system. Where earth fault monitoring is used care should be taken

to ensure that the system 0V to earth potential is not exceeded.

The detector enclosure is to be connected to a local earth and the detector cable screens (shields) should be cut back

to the crotch and not terminated within the detector. If the detector enclosure cannot be connected to a local earth

Installation of the Dräger Flame Detector 5000

then care should be taken to ensure the cable armour braid provides a suitable earth or that the enclosure earth stud

(external) is separately connected to a suitable earth point using a single core 4mm2 earth cable.

All detector cable screens should be connected to the local clean earth at the control panel. The screens (and twisted

pairs) should be maintained to within 1” (25.4mm) of the terminations at the detector, within all junction boxes and at

the control panel. Where unscreened cables are used for panel wiring, then all cables must be suitably twisted into

pairs and video cables should be segregated from other signal sources.

Power Supply

The detector requires an absolute minimum supply voltage of 18V, as measured at the detector terminals. The system

power supply voltage and power distribution should be arranged such that on the longest cable run the detector(s)

has a supply voltage of greater than 18V. All detectors must share a common 0V supply. In distributed systems with

multiple DC-DC power supply units all 0V supplies must be connected together. Where this is not possible the RS485

and Video signals may need to be galvanically isolated, such as with a ﬁ bre optic transceiver.

To prevent RS485 communications or video corruption the maximum voltage drop on the 0V return must not exceed

+4V or -1V. Voltages greater than these will exceed the common mode input range of the RS485 and Video drivers.

Power supply cable selection is described in section: Detector Power Supply Cabling

Detector Wiring Terminals

The wiring terminals and conﬁ guration links are mounted in the rear section of the enclosure and are accessible by

removal of the rear cover from the enclosure. The electronics and the ﬁ eld terminals are separated so that there is no

reason to remove the electronics in order to access the ﬁ eld terminals. This is to prevent damage to the electronics

when the unit is being connected to the ﬁ eld cable.

The device is supplied in one of two options:

As a unit that provides relay contacts for the alarm and fault circuits across which alarm and end of line resistors 1.

are ﬁ tted. When the unit is disconnected from the ﬁ re panel, the output from terminals A and B switch to the

RS485 protocol; this allows a Dräger Engineer access to the detectors conﬁ guration from the local equipment

room.

As a unit that provides 4-20mA output. When the unit is disconnected from the ﬁ re panel, the output from terminals 2.

A and B switch to the RS485 protocol; again this allows a Dräger Engineer access to the detectors conﬁ guration

from the local equipment room.

This may then be used to access the software revision within the detector via the ‘get settings’ menu as described in

the ‘RS485 Communications’ section.

The alarm relay and the 4-20mA output is factory selectable for latching and non-latching operation. If the latching

mode is selected then if an alarm is generated the detector will remain in alarm until the power supply to the unit

is interrupted. If the non-latching operation is selected then the detector will remain in alarm for a minimum of 15

seconds, the ﬁ re panel to which the detector is connected must be capable of latching the alarm and there is no need

to interrupt the power supply to the detector to reset the alarm. Local authority having jurisdiction approval is required

for connection to FM Approved ﬁ re alarm control units.

between terminals 10 & 11 normally appears across terminals 3 & 4 and in the event of a fault the resistor appears open

circuit. If terminals 3 & 4 are disconnected from the ﬁ re panel, these wires then provide a RS485 connection to the

detector. This connection may then be used to up load or down load information to the detector.

RS485 Communications

The optional RS485 twisted pair cable is connected to the detector

RS485A +ve signal terminal and the RS485B -ve signal terminal. The

RS485 connection can be used to read the software revision within the

detector. In order to access this information connect the RS485 input of a

RS485 to RS232 to terminals 7 & 14. Connect the RS232 input of a RS485

to RS232 to a PC install DFG software on the PC. The DFG Software can

be used to interogate the Flame 5000 Detector, for any further assistance

contact Dräger Safety UK Ltd.

The software revision will be shown in the get settings box as indicated

adjacent.

Video (twisted pair)

The video twisted pair cable is connected to the detector +Video signal on

terminal 5 and the -Video signal on terminal 6.

Point to Point Connections

In a point to point connection a single detector is connected to the power, RS485 (or mA or Relays) and Video cables.

This arrangement has the best reliability and availability since any single failure in the ﬁ eld equipment or cabling aﬀ ects

only the one detector.

Cable Selection

The installation, local regulations, and standards determine the overall cable speciﬁ cation. This section speciﬁ es

suitable cable characteristics to ensure correct operation of the ﬂ ame detector. There are several diﬀ erent cabling

methods available, each with advantages and disadvantages:

Three twisted pair cable, one each for DC power, RS485 and video signals•

Two twisted pair cable for DC power and mA or Alarm relays, interchangeable with RS485•

Three twisted pair cable for DC power and mA, or Alarm relays, interchangeable with RS485 and one pair for •

video.

NOTE: Increasing the supply voltage to 26V would increase the maximum cable lengths by +30%.

The overall performance and the transmission distance depends on the selected twisted pair cable. Individually

screened twisted pairs oﬀ er better electrical immunity.

Installation of the Dräger Flame Detector 5000

It is not necessary for the DC power cable to be a twisted pair or individually screened, a 2-core stranded cable with

an overall screen is suﬃ cient. The minimum conductor size is determined by the cable length, the number of Flame

Detectors on each loop, and the maximum allowed voltage drop at the last detector.

To prevent RS485 and Video common mode problems this is limited to a maximum of four volts (4V) on the negative

supply (0V).

Lkm = Cable Length in Kilometres

Rkm = Maximum Conductor Resistance per Kilometre

Use the value of Rkm calculated above to select a suitable gauge of conductor, alternatively, to calculate the maximum

cable length from a known conductor resistance swap Rkm and Lkm in the above equation. The supply voltage and cable

cross-sectional area (which equates to its resistance) limits the maximum cable length, increasing the supply voltage

(up-to a maximum of 32V) can dramatically increase cable length.

Prudence dictates that a cable is selected with a lower resistance than calculated above, with suﬃ cient allowance

for the eﬀ ects of crimps, terminals and ageing which can increase overall resistance. Where a single cable cross

sectional area cannot be found to satisfy both the needs of the power and signal conductors consideration should be

given to using multiple paralleled conductors of a smaller cross section for the power.

Video (Twisted Pair)

The video cabling should be a twisted pair stranded cable with an overall screen. Where multi-core cables are used

then individual screened twisted pairs are recommended. The cable should have the following characteristics:

The maximum cable length is dependent on the cable manufacturer’s attenuation speciﬁ cation, which is approximately

proportional to conductor size.

The characteristic impedance of a transmission line is a function of the physical dimensions of the conductor and the

permittivity of the dielectric (the insulation), at high frequencies this is approximately equivalent to:

Installation Check-Points

Experience has shown that poor installation and commissioning practice may result in an unreliable ﬁ re detection system

that is prone to malfunction, unwanted alarms, and at the same time fails to meet the site performance targets. Before

installing the detector it is important to take into account where it is to be located and how it is to be mounted.

Mechanical Installation

When locating the Dräger Flame Detector 5000 consideration should be given to maintenance access to the •

detector.

The detector mounting should be secure and vibration free.•

It is advisable to check the detection locations, prior to fabrication of the mounting supports, as changes are •

frequently made during construction at site which can aﬀ ect detector coverage.

The installation should allow for easy detector removal for maintenance or repair.•

The detector should be ﬁ xed to a stable supporting structure using the mounting bracket provided. The supporting 1.

structure must allow for horizontal adjustment of the detector orientation. The support structure should be in place

prior to detector installation.

The threaded ﬂ ame path of the enclosure cover and body must be protected from damage during installation. Any 2.

such damage can destroy the validity of the enclosure.

The detector electronics shall be protected from mechanical damage and external sources of EMI such as X-rays, 3.

RFI and electrostatic discharge.

Fit the mounting bracket to the support structure using 8mm bolts (not provided). The detector (bracket) should 4.

be oriented to provide the desired coverage.

The hex head bolts should be ﬁ tted to the enclosure body prior to mounting to the bracket. The detector enclosure 5.

Installation of the Dräger Flame Detector 5000

body should then be ﬁ tted to the mounting bracket. The bolts ﬁ t into key slots in the bracket. Twist the enclosure

to locate the bolts; these are then tightened using a 6mm Allen key.

Electrical Installation

In order to maintain compliance with the EMC regulations it is essential the electrical installation be engineered

correctly.

It is advisable to check the detection locations, prior to fabrication of the mounting supports, as changes are •

frequently made during construction at site.

Detector cabling must be segregated from cables carrying high-speed data or high energy and/or high frequency •

signals and other forms electrical interference.

The detector requires a clear unobstructed view of the local hazard. In order to avoid local obstructions, such as •

pipe-work and cable trays, a 2m helix should be allowed in the detector cabling.

The detector should only be installed just prior to commissioning. Experience shows that the detector can be •

damaged due to cable testing operations (Insulation Tests, etc)

Isolate all associated power supplies. Ensure that they remain OFF until required for commissioning.1.

The threaded ﬂ ame path of the enclosure cover and body must be protected from damage during installation. Any 2.

such damage can destroy the validity of the enclosure.

Operation

Detector Start-up procedure

When the power is initially turned on there is a delay of approximately thirty seconds. The system performs an internal

test and system initialisation.

Detector Signals

The Flame detector generates a 0-20mA signal to indicate its status, or provides relay outputs. This should be checked

during the installation of the detector. Alternatively the status and operation of the device can be monitored by the

colour of the LED illuminated.

WARNING

Operators must be properly trained and aware of what actions to take in the event of a fire being detected.

Status Indicators

The detector LED indicator is used to reveal the Dräger Flame Detector 5000’s current state, as shown below:

Maintenance

Detector Maintenance

WARNING

Repair of all equipment should be only performed in a safe area and by trained personnel.

Once installed there are no user serviceable parts within the detector. The only servicing requirements are to ensure

that the detector is fully functional and to ensure that the lenses are clean.

The terminal compartment cover and front cover threads must be lightly lubricated with non-setting grease prior to

re-assembly.

This maintenance schedule is intended for guidance only. The actual level of maintenance required will depend on

the severity of the operating environment and the likelihood of damage or the rate of contamination from oil, sea spray,

deluge system etc. It is advisable to regularly review maintenance reports and adapt the maintenance period to the

operating environment. A function test of the detectors using the Dräger FS-5000 (See Accessories, page 26) should

be carried out regularly.

Maintenance Intervals

Periodic maintenance checks may be performed in accordance with appropriate codes of practice or local regulations

e.g. in Europe EN 60079-17 applies.

These ﬁ rst ﬁ ve points relate to the general inspection and maintenance of the detector and faceplate, this should be

carried out at least every 6 months.

Detectors that require maintenance should be taken oﬀ line and inhibited. Detectors which require to be opened •

up will need to be isolated electrically. Ensure that panel wiring and terminations associated with all units under

test are in good order.

Ensure that detector mounting arrangements are secure and undamaged.•

Ensure that the detector enclosure is intact and undamaged.•

Ensure that all associated cables and glands are correctly made up, secure and undamaged.•

Clean the enclosure faceplate (outside) with a mild detergent solution and a soft cloth until the window is clear •

of all contamination. Wash the window thoroughly with clean water and dry with a clean lint free cloth or tissue.

Assess requirement for opening the enclosure, for maintenance or cleaning.

The nine points below are for more speciﬁ c inspection and maintenace of the detector enclosure, which should be

performed at least once a year. These points focus as a close external visual inspection and internal inspection if

required.

Open the detector enclosure, if required, by removing the enclosure cover. This exposes the enclosure ﬂ ame path •

and detector electronics. Avoid damage to the ﬂ ame path and faceplate.

Clean the enclosure cover and body ﬂ ame paths with a dry clean cloth to remove any contamination. If the ﬂ ame •

path or threads are badly pitted the component should be replaced.

Fault Finding

Check the ‘O’ ring seal on the enclosure cover to ensure that it is not damaged or perished; replace as required. •

NOTE: That the ingress protection is compromised if the seal is not correct.

Clean the enclosure faceplate (inside) with a mild detergent solution and a soft cloth until the window is clear of •

all contamination. Wash the window thoroughly with clean water and dry with a clean lint free cloth or tissue.

No-setting waterproof grease should be evenly applied to the ﬂ ame path on both the enclosure cover and body.•

Clean the detector lens. This should be done with a soft, dry and clean cloth. Avoid touching the electronics.•

Clean the detector enclosure faceplate. Use a degreasing agent on the outside in order to remove deposits.•

Visually inspect detector electronics and inside the enclosure body for any sign of damage or moisture, replace •

or rectify as required.

The enclosure cover must be screwed on to a minimum of 5 full turns or until fully tight and secured using the •

locking screw provided.

The remaining points cover detector function testing, this should be done on a continuous basis or every 6 months

depending on the environment.

Reinstate the detector back into service.•

Ensure that ‘inhibits’ are applied, then, using the Dräger FS-5000, function test the detector. Note the detector •

LED indicator, within the detector housing, changes colour to RED. Check the complete display system for

correct function and indication.

Functional Testing

The detector can be function tested using the Dräger FS-5000, which has been speciﬁ cally designed to provide a

convenient means of ﬁ eld testing the detector.

CAUTION

Use only Draeger approved parts and accessories wit h t his equipment.

CAUTION

Do not attempt to replace the window as the glass and the front cover are individually matched pairs to me the stringent requirements of the hazardous area certification.

CAUTION

To maintain safety standards, commissioning and regular maintenance should be performed by qualified personel.

Fault Finding

Removal of the Electronics

There are no user replaceable parts within the electronic module, any attempt to repair or dismantle the electronic sub-

assemblies will void the warranty. If any fault is suspected within the electronics module the module is to be returned

to Dräger Safety UK Ltd for investigation and repair if required.

Diagnostics

It is impossible to provide fault diagnostics for every possible detector fault. In all cases it is advised that the following

best practises are followed:

Only make one change at a time (changing more than one part at a time makes diagnosis very diﬃ cult)•

Check the most obvious possible causes ﬁ rst•

Work systematically through the problem•

Keep good notes on the original problem, each step taken and the results observed•

Power Supply

If the detector LED indicator is OFF then there may be a power supply fault. When investigating power supply faults

it is important to check that all voltages are within the detectors operating range (18V - 32V) under full load conditions

as the voltages measured under no load conditions can be misleading.

Live Video Images

The live video signal is susceptible to more potential problems than the alarm signals. The signal is an analogue

transmission and available for operator scrutiny. The cabling is critical to video image quality. Due to the nature of the

video signal, video corruption can appear diﬀ erently on each detector/installation.
