ADDRESSING AND COMMUNICATIONS

Each XP95 device responds to interrogation and commandfrom central control equipment. It communicates to thepanel information on status, command bits, type, location,and other information that allows an alarm to be raisedeven when the device is not itself being interrogated.Message error checking is also provided. The devices arecompatible with Series 90, Discovery® and XPlorer systemsand control equipment to aid maintenance, extension andupgrade of existing systems.

A unique, patented XPERT card provides simple, userfriendly and accurate identification of detector locationwhereby a coded card, inserted in the base, is read by anydetector once it is plugged in. All the electroniccomponents are in the detector but the location informationis held in the base. The address card simplifies and speedsup installation and commissioning. Addressing errorsduring maintenance and service are eliminated.

The XP95 manual call point continues to use DIL switchaddressing, but its interrupt feature also provides automaticreporting of its location in the interrupt mode.

The XP95 detectors provide an alarm facility thatautomatically puts an alarm flag on the data stream andreports its address when the pre-set EN54 thresholds areexceeded. The devices provide great flexibility in systemdesign with the control equipment determining thecharacteristics of the system. A large and growing range ofcompatible control equipment is available from manysources - details are included in Apollo publicationPP1010, which is available on request.

APPLICATION OF XP95 DETECTORS

The choice of detector from the XP95 range follows thewell established principles of system design. That is, theoptimum detector type will depend on the type of fire riskand fire load, and the type of environment in which thedetector is sited.

For general use, smoke detectors are recommended sincethese give the highest level of protection. Smoke detectorsfrom the XP95 range may be ionisation, optical ormultisensor types. It is generally accepted that ionisationtypes have a high sensitivity to flaming fires whereasoptical detectors have high sensitivity to smouldering fires.As a result of this, ionisation types are widely used forproperty protection, and optical types for life protection.These general principles still apply to XP95 detectorsalthough the availability of a multisensor in the range offersmore choice to the system designer.

The multisensor is basically an optical smoke detector andwill therefore respond well to the smoke from smoulderingfires. The detector also senses air temperature. Thistemperature sensitivity allows the multisensor to give aresponse to fast burning (flaming) fires, which is similar tothat of an ionisation detector. The multisensor cantherefore be used as an alternative to an ionisation detector

Where the environment is smoky or dirty under normalconditions, a heat detector may be more appropriate. Itmust be recognised, however, that any heat detector willrespond only when the fire is well established andgenerating a high heat output.

Unless otherwise specified, devices described in this guideare suitable for indoor use only.

is that a small electric currentflows between the electrodes.At the junction between thereference and smoke chambersis the sensing electrode that isused to convert variations inthe chamber currents into avoltage.

When smoke particles enterthe ionisation chamber, ionsbecome attached to themwith the result that the currentflowing through the ionisationchamber decreases. Thiseffect is greater in the smokechamber than in thereference chamber and the

imbalance causes the sensingelectrode to go morepositive.

The voltage on the sensingelectrode is monitored by thesensor electronics and isprocessed to produce asignal that is translated by theA/D converter in thecommunications ASIC readyfor transmission when thedevice is interrogated.

XP95 IONISATION SMOKE DETECTOR

XP95 Ionisation Smoke Detector Part Number 55000-500

OPERATINGPRINCIPLES

The XP95 ionisation smokedetector has a mouldedself-extinguishing whitepolycarbonate case withwind resistant smoke inlets.Stainless steel wiper contactsconnect the detector to theterminals in the mountingbase. Inside the detector caseis a printed circuit board thathas the ionisation chambermounted on one side and theaddress capture, signalprocessing and communicationselectronics on the other.

The ionisation chambersystem is an inner referencechamber contained inside an

Fig.2 Sectional view - XP95 Ionisation Smoke Detector

outer smoke chamber (Fig 2).The outer smoke chamberhas smoke inlet aperturesthat are fitted with an insectresistant mesh.

The radioactive sourceholder and the outer smokechamber are the positiveand negative electrodesrespectively. An Americium241 radioactive sourcemounted within the innerreference chamber irradiatesthe air in both chambers toproduce positive andnegative ions. On applying avoltage across theseelectrodes an electric field isformed as shown in Fig 3.The ions are attracted to theelectrode of the oppositesign, some ions collide andrecombine, but the net result

ELECTRICALDESCRIPTION

The detector is designed tobe connected to a two wireloop circuit carrying bothdata and a 17V to 28V dcsupply. The detector isconnected to the incomingand outgoing supply viaterminals L1 and L2 in themounting base. A remoteLED indicator requiring notmore than 4mA at 5V maybe connected between +Rand -R terminals. An earthconnection terminal is alsoprovided, although this isnot required for thefunctioning of the detector.

When the device is energisedthe ASICs regulate the flowof power and control the dataprocessing. The ionisationchambers are energised andthe ultra low leakage sensorASIC provides a conditionedanalogue signal to theanalogue to digital (A/D)converter within thecommunications andprocessing ASIC. Whensmoke enters the ionisationchambers through the integralgauze, the voltage at thesensing electrode increases toproduce an analogue signal.An A/D conversion of thesignal from the ionisationchambers is carried out onceper second or when eitherthe detector or precedingaddress is being interrogated.Whenever the device isinterrogated this data is sentto the control equipment.EN54 threshold alarm levelsare calibrated within theprocessing ASIC. If thedevice is not addressedwithin 1 second of its lastpolling and the analoguevalue is greater than 55 the

alarm flag is initiated andthe device address is addedto the data stream every 32polling cycles from its lastpolling for the duration ofthe alarm level condition,except when the alarmingdevice is being interrogated.This can provide a locationidentified alarm from anydevice on the loop inapproximately two seconds.

The detector is calibrated togive an analogue value of25±7 counts in clean air. Thisvalue increases with smokedensity. A count of 55corresponds to the EN54 alarmsensitivity level. See Fig 4.Counts of 8 or less indicatefault conditions. Count levelsbetween 45 counts and 55counts can be used to providean early warning of fire.

ENVIRONMENTALCHARACTERISTICS

XP95 ionisation smokedetectors are designed tooperate in a wide variety ofenvironments (See Figs 5 to7). There are only smalleffects from temperature,humidity, atmosphericpressure and wind. Detectorsare well protected againstelectromagnetic interferenceover a wide frequency range.

The XP95 ionisation detector,like all ionisation detectors,has some sensitivity to airmovement (wind). Theextent to which the analoguevalue will change dependson the wind speed and onthe orientation of thedetector relative to the winddirection. Relatively smallchanges in wind directioncan cause significant changesin analogue value.

SAFETY NOTE

In the United Kingdom,ionisation smoke detectors aresubject to the requirements ofthe Radioactive SubstancesAct 1993 and to the IonisingRadiations Regulations 1999made under the provisionsof the Health and Safety atWork Act 1974.

The detectors, independentlytested by the NationalRadiological ProtectionBoard (NRPB), conform to allthe requirements specifiedin the ‘Recommendations forionisation smoke detectors inimplementation of radiation

standards’ published by theNuclear Energy Agency of theOrganisation for EconomicCo-operation andDevelopment (OECD) 1977.

There is no limit to the numberof ionisation smoke detectorswhich may be installed inany fire protection system.

Storage regulations dependon local standards and thelegislation, but, in the UK, upto 500 detectors may be storedin any premises, althoughthere are stipulations onstorage facilities if more than100 ionisation detectors arestored in one building.

At the end of theirrecommended working lifeof ten years, ionisation

smoke detectors should bereturned to Apollo for safedisposal or disposed of in anotherwise locally approvedand environmentally safemanner. Please see "A Guideto the Care, Maintenanceand Servicing of ApolloProducts", PP2055.

Guidance on storage can begiven by Apollo FireDetectors and full detailscan be requested from:

Radioactive SubstancesRegulation FunctionEnvironment AgencyRio House, Waterside DriveAztec West, Almondsbury, Bristol, BS32 4UD

Outside the UK, please contactthe relevant national agency.

For wind speeds up to 1m/s(200ft/min) the change inanalogue value will notexceed 5 counts.Continuous operation inwind speeds greater than2m/s (400ft/min) is notrecommended. However,wind speeds up to 10m/s(2000ft/min) can be toleratedfor short periods and willnot under any conditionsincrease the probability offalse alarms.

XP95 Optical Smoke Detector Part Number 55000-600

OPERATINGPRINCIPLES

The XP95 optical detectoruses the same outer case asthe ionisation smokedetector and is distinguishedby the indicator LED whichis clear in standby and red inalarm. Within the case is aprinted circuit board whichon one side has the lightproof labyrinth chamber withintegral gauze surroundingthe optical measuring systemand on the other the addresscapture, signal processing andcommunications electronics.

An infrared light emittingdiode within its collimator isarranged at an obtuse angleto the photo-diode. Thephoto-diode has an integraldaylight-blocking filter.

The IR LED emits a burst ofcollimated light every second. Fig.8 Top section - XP95 Optical Smoke Detector

In clear air the photo-diodereceives no light directlyfrom the IR LED because ofthe angular arrangementand the dual mask. Whensmoke enters the chamber itscatters photons from theemitter IR LED onto thephoto-diode in an amountrelated to the smokecharacteristics and density.The photo-diode signal isprocessed by the opticalASIC and passed to the A/Dconverter on thecommunications ASIC readyfor transmission when thedevice is interrogated.


The detector is designed tobe connected to a two wireloop circuit carrying bothdata and a 14V to 28V dc

supply. The detector isconnected to the incomingand outgoing supply viaterminals L1 and L2 in themounting base. A remoteLED indicator requiring notmore than 4mA at 5V maybe connected between the+R and -R terminals. Anearth connection terminal isalso provided.

When the device is energisedthe ASICs regulate the flowof power and control thedata processing. The opticalASIC is controlled by thecommunications ASIC andpulses the IR LED. Thesignal from the photo-diodeis processed by the opticalASIC and transferred to theA/D converter in thecommunications ASICwhere it is then stored.When smoke enters thechamber the photo-diodesignal increases. Theinformation to the A/Dconverter is updated onceper second or when eitherthe monitor or the precedingaddress is interrogated.Whenever the device isinterrogated this data is sentto the control equipment.EN54 threshold alarm levelsare calibrated within theprocessing ASIC. If the

device is not addressedwithin 1 second of its lastpolling and the analoguevalue is greater than theEN54 alarm level the alarmflag is initiated and thedevice address is added tothe data stream every 32polling cycles from its lastpolling for the duration ofthe alarm level condition,except when the alarmingdevice is being interrogated.This can provide a locationidentified alarm from anydevice on the loop inapproximately 2 seconds.

The detector is calibrated togive an analogue value of25±7 counts in clean air.This value increases withsmoke density. A count of 55corresponds to the EN54 alarmsensitivity level. See Fig.10.


The XP95 optical smokedetector is unaffected bywind or atmosphericpressure and operates overthe temperature range -20°Cto +60°C. See Fig. 11.

the smoke level and the airtemperature respectively inthe vicinity of the detector.The detector’s microcontrollerprocesses the two signals.The temperature signalprocessing extracts only rateof rise information forcombination with the opticalsignal. The detector will notrespond to a slow temperatureincrease - even if the

temperature reaches a highlevel. A large sudden changein temperature can, however,cause an alarm without thepresence of smoke, ifsustained for 20 seconds.

The processing algorithms inthe multisensor incorporatedrift compensation. Thecontrol panel must not havea drift compensationalgorithm enabled.

The sensitivity of the detectoris considered the optimumfor most general applicationssince it offers good responseto both smouldering andflaming fires.

XP95 20D ISOLATING BASE

OPERATINGPRINCIPLES

The XP95 20D isolating basesenses and isolates shortcircuit faults on XP95 loopsand spurs. The base is looppowered, polarity sensitiveand accepts the XPERT cardto set the associated deviceaddress.

In short circuit conditionsthe integral yellow LED isilluminated. The detectorassociated with the baseremains active under shortcircuit conditions. Powerand signals to the affectedsection are restoredautomatically when the faultis cleared.


Under normal operatingconditions, a low impedanceis present between the –INand –OUT terminals of thebase, so that power andsignals pass to the next basein the line.

If a short circuit or abnormallylow impedance occurs, thefall in voltage is sensed andthe base isolates the negativesupply in the direction ofthe fault.

In applications where it is notnecessary to use an isolatingbase for each detector, upto twenty devices (detectorsand XP95 interfaces) maybe installed betweenisolating bases, provided that

their total switch-on surgecurrent does not exceed 20mA.

Circuits may include spurs,which should be connectedbetween the spare –OUTterminal and the base L1terminal. Spurs connectedin this way appear directlyacross the loop on theoutput side of the isolatingbase. Short-circuit faults onthe spur therefore shortcircuit the loop and viceversa. The effect of suchshort circuits must be takeninto account in the systemdesign and may require theuse of extra isolating bases.

‘Stand-alone’ isolators,which have their ownbases, may be used insteadof isolating bases. Theisolators are wired to a loopbetween detectors or otherdevices.

XP95 Loop-Powered BeamDetector

Part Number: 55000-265

The XP95 optical beamdetector has been designedto protect large open spacessuch as museums, churches,warehouses and factories. Itconsists of three main parts:the transmitter, which projectsa beam of infra-red light,the receiver, which registersthe light and produces anelectrical signal, and theinterface, which processesthe signal and generatesalarm or fault signals.

The transmitter and receiverare designed to be fitted onopposite walls approximately30cm to 60 cm below thelevel of the ceiling. Theycan protect an area up to100m long and 15m wide, atotal of 1500m2.

The interface contains theelectronic circuitry neededto control the beam detectorand communicate with thecontrol panel via the XP95loop.

The beam detector is loop-powered and needs noseparate 24V supply. Thisnot only eliminates the needfor additional equipment, italso saves both cost andtime in installation.

MiniDisc Remote Indicator


A light-weight, compactindicator for use in fireprotection systems. Theindicator may be used in allinstallations incorporatingSeries 60, XP95, Discoveryand Intrinsically Safedetectors. It is only 20mmhigh and 80mm in diameter.It comprises two parts – thebase, which is installed ontoa wall or soffit and the lid,which is fitted to the basewith a bayonet lock.

100dB(A) Loop SounderPart Number: 55000-261There are two types of loop-powered sounder available,allowing fire engineers tospecify not only the soundoutput but also thefunctionality of individualsounders.

The 85dB(A) Low-Profileloop sounder is intended foruse in confined spaces suchas hotel rooms and corridors.It is designed to have a baseand detector mounted uponit, but can also be used as astand-alone sounder. The100dB(A) loop sounder isintended as an open-spacesounder, where a higheroutput is required.

Both sounders are poweredby the loop and controlledby a control panel using theXP95 protocol. Both havelow current consumption –typically 3 to 4.5mA inalarm. Both sounders aredesigned to comply withBS5839, Part 1:1998.
