1.1 Introduction.
The BeaconMedaes Medical Gas Supply System,
mainly consists of cylinder manifold system, manifold
changeoversystem,header&tailpipeandothernecessary
components, is intended to work in conjunction with
other devices within the medical gas pipeline system
(MGPS) to assist with maintaining continuity of supply
throughout the hospital to local connection points for
eventualintroductionintothehumanbody.Thedevice
controls the gas pressure within the specication as
requiredbytheMGPS.Inallcasesotherdevicesoutside
of this scope are connected downstream of the MGPS
arerequiredtocontrolthenalgaspressureandow
requirementsforsafesupplytothepatient.Therefore,
thisdeviceisnotintendedtocontrolsupplyparameter
hazardsdirectlytothepatient,onlytotheMGPS.
The device including Cylinder Manifold System and
Manifold Changeover System (abbreviate as manifold
below) is principally designed for use as a primary or
secondarysourceofsupply,orforemergencybackup.
The Medical Gas Supply System supplies one of the
followingmedicalgasestoapipeddistributionsystem,
Oxygen,NitrousOxide,O2/N2O50%:50%,MedicalAir,
SurgicalAir,Nitrogen&CarbonDioxide.

Modular manifold headers for gas cylinders can be
connected to the Manifold Changeover System to
congureitsgassupplycapacity.
The Manifold Changeover System is connected to the
pipelinedistributionsystemupstreamoftheemergency
supply, or downstream of the primary supply system
when used as backup. It can be isolated from the
pipeline distribution system by the lockable isolation
valvesupplied.Whenusedasabackupsupplythisvalve
should be left open during normal operation, so the
unit will automatically supply the pipeline distribution
system with medical gas in the event of the primary
systemfailingtosupply.
When used as a backup manifold system the line
pressureshouldbeset slightlylower thanthe primary
supplypressuretopreventtheunitfromsupplyinggas
duringnormaloperationoftheprimarysupplysystem.
1.2 1stStagePressureRegulator.
Forsafe operation regardingperformance, mechanical
strength, resistance to ignition in pure high pressure
oxygensupplyandcleanliness,thedevicefullyconforms
toBSENISO10524-2.Apressurereliefvalveconnected
totheregulatorprotectsthedownstreampressureand
isseta2410kPa(24.1bar).
1.3 2ndStagePressureRegulator.
Forsafe operation regardingperformance, mechanical
strengthandcleannessthedevicefullyconformstoBS
ENISO10524-2,thesecondstagepressureregulatoris
a manually set diaphragm type and is used to set the
systempressure to suit typical nominalvalues for 4, 8
and11barpipelinesystems.
NOTE - To maximise performance each 2nd stage
pressureregulatoristtedwithinternalspringsspecic
tomatchthenominallinepressure.
1.4 LinePressureReliefValve.
Thelinepressure reliefvalves arepreset tothe values
shown in table 1 for the dierent line distribution
pressures.
Table 1: Line Pressure Relief Valve Set Points.
ReliefValveSetPoint Nominal Distribution

1300kPa(13bar) 1100kPa(11bar)
The line pressure relief valve is tted between the
pressure regulator and the isolation valve, thus
protectingthedeliverysystemfromoverpressurisation
bydischargingtoatmosphereintheeventofregulator
failure.

1.6 Halogen Free Components.
The Medical Gas Supply System contains NO

may experience pressurised oxygen in excess of 3000

Pressuredropleaktestvalidationnotes:
• The Manifold Changeover System uses medical
regulatorsapprovedtoBSENISO10524-2standard,
as required by ISO and HTM medical pipeline
standards.  These standards have a maximum
allowableleakageacrosstheregulatorseat(internal)
andtoatmosphere(external)asfollows:
1ststageregulator,Internal 0.1ml/min
1ststageregulator,external 0.2ml/min
2ndstageregulator,Internal 0.2ml/min
2ndstageregulator,external 0.2ml/min
• Therefore, the maximum pressure increase or
decrease witnessed at the line pressure will be
based on 2 regulators, 0.4 ml/min.  The maximum
pressure drop witnessed at the cylinder pressure
will be based on the internal and external leakage
fromthe1st and 2ndstageregulatoronthatbank,0.7
ml/min.
• Pressuredroptestsaremorecommonlyusedonsite,
asleakscanbediculttomeasure.Theequivalent
watercapacityvolumeundertestisusedtocalculate
thepressuredropfromanallowableleakagerate.
• Fromusingthemanifoldwatercapacitytheallowable
pressuredroporincreasebasedonaleakageof0.4
ml/mincanbecalculatedas0.0016bar/min,or0.096
bar/hrwitnessedatthelinepressure.Thepressure
dropwitnessedatthecylinderpressurefroma0.7
ml/min leakage would be as follows depending on
thenumberofcylinderconnections.
No.Cyl. 12345
Bar/Hr 1.78 1.09 0.78 0.61 0.5
No.Cyl. 67 8 9 10
Bar/Hr 0.42 0.37 0.33 0.29 0.26
• Althoughthemedicalregulatorallowableleakageis
onlysmall,theeectscanbewitnessedwithinafew
hours due to the manifold having a small volume.
To put into perspective how small 0.4 ml/min is, if
appliedtooneJ-sizecylinderitwouldtakenearly12
weeksforittodropby1bar.
2.6.8 Monitorthepressuredropandassessasperthe
abovenotes.Lengthoftimeforthetestwilldependon
theaccuracyofthegaugesusedtobeabletodetectthe
pressuredrop.
2.6.9 Opentestpointisolationvalve(gure1,item15)
andrelievethepressurefromwithinthemanifold,then
closetestpointisolationvalve.
2.6.10 TheinstallationmustnowbepurgedasperHTM
02-01forUKinstallations,orasperrelevantstandardsif
installedoutsidetheUK.
2.6 Installation Check.
2.6.1 Ensure that all tailpipes are connected to the
cylinders and manifolds on both sides and that the
restraintchainsaresecurearoundthecylinders.
2.6.2 Isolate the device from the pipeline using the
mainisolationvalve(showningure15,item3).
2.6.3 Ensure that both bank isolation valves (Figure
15,item1and2)arefullyopen.
2.6.4 Ensurethe test point isolation valve(gure 15,
item4)isclosed.
2.6.5 Use 1 cylinder per bank, slowly pressurise the
manifold (see section 4.10 - Cylinder operation). Both
cylinder gauges (gure 1, item 23) should indicate full
cylinderpressure.Thelinepressuregauge(gure1,item
18)shouldreadtypicallyaspertable6,Section4,adjust
asnecessary(seesection4.5).
 CAUTION!Ifusedasabackupmanifolditwould
berecommendedtosetthelinepressureatleast0.2bar
below the main supply source pressure at full design
ow,toensurethemanifolddoesnotsupplythepipeline
duringnormalprimarysourceoperation.
2.6.6 Check for leaks, typically by listening for gas
escapingorleakdetectionuidonjoints.
