Discovery MarineOptical Smoke Detector
Operating principles
The Discovery Marine Optical Smoke Detector has a whitemoulded polycarbonate case with wind-resistant smoke inlets.
The indicator LEDs are colourless when the detector is inquiescent state and red in alarm. Within the case is a printed
circuit board which, on one side, has the light-proo chamberwith integral gauze surrounding the optical measuringsystem and, on the other, the signal processing andcommunications electronics.
An inra-red light emitting diode within its collimator isarranged at an obtuse angle to the photo-diode. Thephoto-diode has an integral daylight-blocking lter.
The IR LED emits a burst o collimated light every second (Fig 1).In clear air the photo-diode receives no light directly rom theIR LED, because o the angular arrangement and the chamberbafes. When smoke enters the chamber it scatters lightrom the emitter IR LED onto the photo-diode in an amount
related to the smoke characteristics and density. The photo-diode signal is processed to provide an analogue value ortransmission when the detector is interrogated.

Discovery MarineMultisensor Detector
Operating principles
The Discovery Marine Multisensor Detector construction issimilar to that o the optical detector but uses a dierent lidand optical mouldings to accommodate the thermistor (heatsensor). The sectional view (Fig 1) shows the arrangement o
the optical chamber and the thermistor.
The Discovery Marine optical/heat multisensor detectorcontains an optical smoke sensor and a thermistor temperaturesensor whose outputs are combined to give the nal analoguevalue. The way in which the signals rom the two sensors arecombined depends on the response mode selected. The vemodes provide response behaviour which incorporates pureheat detection, pure smoke detection and a combination oboth. The multisensor is thereore useul over the widest rangeo applications.
The signals rom the optical smoke sensing element andthe temperature sensor are independent, and represent the
smoke level and the air temperature respectively in the vicinityo the detector. The detectors micro-controller processesthe two signals according to the mode selected. When thedetector is operating as a multisensor (i.e. modes 1, 3 and 4)the temperature signal processing extracts only rate-o-riseinormation or combination with the optical signal. In thesemodes the detector will not respond to a slow temperatureincrease even i the temperature reaches a high level. A largesudden change in temperature can, however, cause an alarmwithout the presence o smoke, i sustained or 2 seconds.
Additionalheatsensorinformation
Discovery Marine optical/heat multisensor detectors
manuactured rom mid 29 incorporate additionaltemperature inormation that is intended or use insignal processing.
Temperature data can be read separately by the control panel(see Note 1) and used to validate an alarm signalled by themultisensor analogue value. An example o this would bea high multisensor analogue value not accompanied by anincrease in heat: this would indicate that an agent other thansmoke, e.g. steam, had caused the high analogue value.

Characteristics o the response modes
The processing algorithms in modes 1 to 4 incorporatedrit compensation.
The characteristics o the ve response modes are
summarised below.Mode 1 has very high smoke sensitivity combined with highheat sensitivity. This gives a high overall sensitivity to bothsmouldering and aming res.
Mode 2 has a smoke sensitivity similar to that o a normaloptical smoke detector. This mode is thereore equivalent to astandard optical detector. I t is suitable or applications in whichwide temperature changes occur under normal conditions.
Mode 3 has moderate smoke sensitivity combined with amoderate sensitivity to heat. This combination is consideredthe optimum or most general applications since it oers goodresponse to both smouldering and aming res.
Mode 4 has lower than normal smoke sensitivitycombined with high heat sensitivity. This makes it suitableor applications in which a certain amount o umes or smokeis considered normal.
Mode 5 has no smoke sensitivity at all, but gives a pure heatdetector response meeting the response time requirements ora Class A1R detector in the European standard EN545:2.In this mode the detector will respond to slowly changingtemperatures and has a xed temperature alarm threshold at58C. The analogue value in this mode will give the approximateair temperature over the range 15C to 55C.
In mode 5, the smoke sensor is still active though it does notcontribute to the analogue signal. As a consequence, i thedetector is used in a dirty or smoky environment the opticalsensor drit ag may be activated in the heat-only mode.
Notes
1. This applies only to panels which have been programmedto read the additional inormation.
2. In situ testing o the multisensor detector should be carriedout as or smoke detectors in response mode 2 and orheat detectors in response mode 5. Both optical and heatsensors must be tested in modes 1, 3 and 4.
3. I the multisensor is to be used in mode 5, heat detectorspacing/coverage should be applied.

Discovery MarineIonisation SmokeDetector
Operating principles
The Discovery Marine Ionisation Smoke Detector uses the sameouter case as the optical smoke detector and is distinguishedby the red indicator LEDs. Inside the case is a printed circuitboard which has the ionisation chamber mounted on one side
and the signal processing and communications electronics onthe other.
The ionisation chamber consists o a reerence chambercontained inside a smoke chamber (Fig 1). The outer smokechamber has inlet apertures tted with insect resistant mesh.
At the junction between reerence and smoke chambers, thesensing electrode converts variations in chamber current intovoltage changes.
When smoke particles enter the ionisation chamber, ionsbecome attached to them with the result that the currentowing through the chamber decreases. This eect is greater
in the smoke chamber than in the reerence chamber, andthe imbalance causes the sensing electrode to becomemore positive.
The analogue voltage at the sensor electrode is converted to adigital ormat which is processed to provide an analogue valueor transmission to the control panel when the device is polled.
The Discovery Marine Ionisation Detector, like all ionisationdetectors, has some sensitivity to air movement (wind). Theextent to which the analogue value will change depends onthe wind speed and on the orientation o the detector relativeto the wind direction. Relatively small changes in wind directioncan cause signicant changes in analogue value.
For wind speeds up to 1m/s (2t/min) the change in analoguevalue will not exceed 5 counts. Continuous operation in windspeeds greater than 2m/s (4t/min) is not recommended.However, wind speeds up to 1m/s (2t/min) can betolerated or short periods and will not under any conditionsincrease the probability o alse alarms.
Ionisation smoke detectors are supplied in individual packingwith a red lid serving as a dust cover which can be let inplace ater tting to prevent ingress o dust and dirt untilcommissioning o the system takes place. At this point thecovers must be removed.

Discovery MarineHeat Detector
Operating principles
Discovery Marine Heat Detectors have a common prole withionisation and optical smoke detectors but have a low air owresistance case made o sel-extinguishing white polycarbonate.
The Discovery Marine Heat Detector uses a single thermistorto sense the air temperature at the detector position. Thethermistor is connected in a resistor network, which producesa voltage output dependent on temperature. The design o theresistor network, together with the processing algorithm in themicrocontroller, gives an approximately linear characteristicrom 1C to 8C. This linearised signal is urther processed,depending on the response mode selected, and converted toan analogue output.
For the European standard version o the detector, the vemodes correspond to ve classes as dened in EN545:21.
The classes in this standard correspond with dierent responsebehaviour, each o which is designed to be suitable or a range
o application temperatures. All modes incorporate xedtemperature response, which is dened in the standard by thestatic response temperature. The application temperatures andstatic response temperatures or all response modes are givenin Table 4.
In addition to the basic classication, a detector may be givenan R or S sux. The R sux indicates that the detectorhas been shown to have a rate-o-rise characteristic. Such adetector will still give a rapid response even when startingrom an ambient temperature well below its typical applicationtemperature. This type o detector is thereore suitable orareas such as unheated warehouses in which the ambient
temperature may be very low or long periods.The S sux on the other hand indicates that the detector willnot respond below its minimum static response temperatureeven when exposed to high rates o rise o air temperature.
This type is thereore suitable or areas such as kitchens andboiler rooms where large, rapid temperature changes areconsidered normal.

Case StudyLiao Hai Ferry
The Liao Hai is a roll-on-roll-o erry. Measuring
115m long and 21m wide, it has the capacityto transport 65 people and approximately
1 lorries. The China Tian jin XinGang shipyard
awarded the contract to supply an intelligent re
detection system or the Liao Hai, a new roll-onroll-o erry, to Apollos local representative
Shanghai Jin Zhou.
The re detection system includes around2 Apollo intelligent detectors, including
multisensors, which have been approvedor marine applications by the China
Classication Society ollowing additionaltests specic to the marine environment.
Most o the detectors used on the vessel havebeen tted using Apollos Deckhead Mounting
Base. This is a robust back box, made rom either
aluminium or polycarbonate, or use with standard
1mm detector bases. Fixing points are external,
enabling a seal to be maintained and thereoreproviding protection against contaminant ingress
into the rear o the base. These boxes
are particularly useul when securing basesto rough suraces or in areas where there
may be dripping water.
The Liao Hai re detection system allows a two
minute delay in the event o an alert so thatan incident can be investigated. I the alert is
genuine, the system then proceeds to raise the
alarm. Apollo zone monitors with inbuilt isolators
have been installed to enable the re detectionsystem to interace with other critical equipment
on board. A re alarm triggers a preset sequence
o events to ensure that passengers can beevacuated saely. Actions include operating redoors and dampers and closing down the air
conditioning to the passenger and car decks to
prevent the spread o smoke.

In short-circuit conditions the integral yellow LED is illuminated.The detector associated with the base remains active undershort-circuit conditions. Power and signals to the aectedsection are restored automatically when the ault is cleared.
Protocol compatibility
The Isolating Base is intended or use with equipment using theApollo XP95 and Discovery communication protocol.
Operation
Under normal operating conditions, a low impedance is presentbetween the IN and OUT terminals o the base, so that powerand signals pass to the next base in line.
I a short-circuit or abnormally low impedance occurs, the allin voltage is sensed and the base isolates the negative supplyin the direction o the ault. The isolated section is tested usinga current pulse every ve seconds. When the short-circuit isremoved, the power will automatically be restored.
I it is a requirement that no device is lost in the event o asingle short-circuit ault, every detector should be tted to anisolating base.
In applications where it is not necessary to use an isolating base
or each detector, up to twenty detectors or equivalent surgecurrent may be installed between isolating bases. See PIN sheetPP29 or ull inormation on loop loading between isolatingbases.
Consult engineering guides or PIN sheets or quiescent currentvalues o protected devices.
Mechanicalconstruction
The isolating base is a sel-extinguishing polycarbonatemoulding with nickel-plated steel terminals or connecting adetector. The associated detector can be locked into the baseusing the normal locking screw.

Discovery Marine Manual Call Point with Isolator
Technical description
The Discovery Marine Manual Call Point (MCP) is based on theKAC conventional MCP range. It is electronically and mechanicallycompatible with previous Apollo call points based on KACs WorldSeries product.
The address o each call point is set at the commissioningstage by means o a seven-segment DIL switch.
I a MCP is activated, it interrupts the normal protocol to givea ast response.
A single bi-coloured alarm LED is provided on the manual callpoint. This LED is controlled, independently o the call point, bythe control panel and may be set to ash each time the call pointis polled. The red LED is illuninated when the call point has beenactivated and sent into alarm. On the isolated versions an amber/yellow LED indicates a short-circuit on the loop wiring either sideo the call point.
Call points can be remotely tested rom the panel by transmissiono a single bit in the communications protocol. Call pointsrespond by providing a value o 64 which corresponds to thealarm value. The panel should recognise this response as a testsignal and should not raise a general alarm.
Discovery Marine manual call points are available with or withoutan isolator. Each version is available with a resettable element anda backbox or surace mounting as standard. I a glass option isrequired, spare glasses are available on request.
For ease o installation Discovery Marine manual call points aresupplied with clip-on terminal blocks and a connector whichallows continuity testing beore call points are commissioned.
To provide additional protection against accidental operation, atransparent hinged cover with a locking tag, part number 26729-152 is available, which can be tted to the manual call point.Please note that the call point does not conorm to EN54-11:21when this lid is tted and secured with the locking tag.

Discovery MarineSounder VisualIndicator Base
45681-394MAR
Discovery Marine Sounder Visual Indicator Base
The Discovery Marine Sounder Visual Indicator Base is amultiunctional device comprising a mounting base orDiscovery Marine re detectors, a sounder, a visual indicator anda short-circuit isolator.
Application
The Discovery Marine sounder visual indicator base is usedto provide audible and visual warning o re and is controlledby the re control panel by means o the Discovery protocol.
The particular eatures o this base are available only when it isbeing controlled by the ull Discovery protocol with the panelprogrammed accordingly. Inormation on eatures should berequested rom the panel manuacturer.
The Discovery Marine sounder visual indicator base can be usedwith a detector tted or with a cap or operation as a stand-alone alarm device.
Therighttoneforyourinstallation
The Discovery Marine sounder visual indicator base oersa choice o 15 evacuation tones, including the standardApollo evacuation tone. One o these tones is selected duringcommissioning in order to suit local regulations or customs.
The tones include those required by Dutch, Swedish, German,Australian, New Zealand and North American standards as wellas the UK.
Whichever evacuation tone is selected there is a secondarytone which may be used or alerting or warning o a possibleevacuation.
Therightlevelofsound
The sounder is set during commissioning to one o 7 levels osound, the highest level being nominally 9dB(A).
At 6dB(A) the lowest level alls outside the scope o thestandard, EN54. It has been included to provide a very localwarning or the use o personnel in particular environments,such as nurse stations in hospitals.
Flexibilityofgroupaddressing
In many installations a re alarm must be raised by switchingmore than one sounder visual indicator to alert or alarmsimultaneously. This is achieved with Discovery Marine soundervisual indicator bases by assigning devices to groups on
commissioning, with the group inormation being stored ineach device. One command will then switch all devices inthe group.

Sounder,visualindicatororboth
The Discovery Marine sounder visual indicator base normallyswitches both sounder and visual indicator to provide an alertor evacuation signal. The sounder and visual indicator o theDiscovery Marine sounder visual indicator base can, however,
be switched independently o each other by the control panel.
Location-specicvolumesetting
Detectors and sounder visual indicators are installed in manydierent types o environment.
When conguring the Discovery Marine sounder visualindicators base the adjustment o volume can be done at thepoint o installation.
The commissioning engineer simply sets the control panel toSetup and then walks rom one device to the next to set therequired volume, using a magnetic wand, part no 2965-1.When all devices have been set the control panel is used to
register all the individual volume settings.

Marine DIN-Rail Dual Isolator
The Marine DINRail Dual Isolator provides, in one housing, twoindependent isolators which sense and isolate short-circuits onloops and spurs.
The isolators are loop-powered and are polarity sensitive.A maximum o twenty detectors may be installedbetween isolators.
When a short-circuit condition exists on either side o theisolator, its yellow LED is illuminated.
Under normal operating conditions, a low impedance is presentbetween the two negative terminals o each isolator channel sothat power and signals are passed to the next base in line.
I a short-circuit or abnormally low impedance occurs across theloop, the all in voltage is sensed and the isolator isolates thenegative supply in the direction o the ault. In this condition,the yellow LED o the aected channel will be illuminated. Theisolated section o loop is tested using a current pulse everyve seconds. When the short-circuit is removed the power will
automatically be restored.

Features UV
The detector is sensitive to ultraviolet radiation emitted byames during combustion. Since it requires only UV radiationthe detector responds even to stationary ames with no ickerlike cigarette lighters and blue gas ames.
The detector is set to respond to ultraviolet radiation(18526nm) emitted by almost all ames, including thoseinvisible to the naked eye, e.g. hydrogen res.
The detector has a single UV sensor with a narrow spectralresponse in order to discriminate between ames and mostspurious sources o radiation and is designed or internal ullyenclosed areas.
Caution: The detector will also detect electrical discharges romlightning or arc welding.
UV/DualIRThe detector is sensitive to ultraviolet and low- requency,ickering inra-red radiation emitted by ames duringcombustion. Since it requires both UV and IR radiation thedetector can operate in applications where a basic single UVor single IR detector would be inappropriate. The detector isset to respond to ultraviolet (18526nm) and low- requencyickering inra-red (.752.7m) radiation at 115Hz in order
to detect all ickering ames, including those invisible to thenaked eye, e.g. those emitted by hydrogen res. The detectorhas one UV and two IR sensors responding to dierentwavelengths in order to discriminate between ames and
spurious sources o radiation. False alarms due to electricaldischarges rom lightning or arc welding and ickering sunlightare minimised by combining the UV/IR signals.
IR3
The detector is sensitive to low-requency, ickering inra-red radiation emitted by ames during combustion. Since itresponds to ickering radiation the detector can operate eveni the lens is contaminated by a layer o oil, dust, water-vapouror ice. The detector is set to respond to low-requency radiationat 115Hz (.752.7m) in order to detect all ickering ames,
including those invisible to the naked eye, e.g. those emitted byhydrogen res. The detector has three IR sensors that respondto dierent IR wavelengths in order to discriminate betweenames and spurious sources o radiation. False alarms due toactors such as ickering sunlight are avoided by a combinationo lters and signal processing techniques.
Applications or Flame Detectors UVUV Flame Detectors are used when detection is required to beunaected by convection currents, draughts or wind. Theseinclude engine rooms in ships, actories aected by draughts orwind and warehouses.
They are ast reacting and respond to a ame more than25m away. The UV ame detector is aected by arc welding,electrical sparks, lightning, nuclear radiation and UV lightsources. For applications where these phenomena are presenta UV ame detector should not be used.
UV/DualIRThis detector is not aected by any o the sources mentionedabove. They are used in aircrat hangers, generator rooms (dieseland gas turbines) and paint works.
IR3
The IR3 ame detector is also ast reacting but is also tolerant oumes, vapours, steam, dust and mist, while being unaectedby the phenomena listed above. It may, however, be aectedby modulated IR radiation. Triple IR ame detectors are used inwaste handling, colour printing and paper manuacturing.
*Full a ull list o applications or Apollo ame detectors, pleasereer to PP249, available on request.
Protocol compatibility
The detectors operate only with control equipment using theApollo Discovery digital protocol (or any development o it).
The eld o view o the ame detector is shown in the Fig 1.This also provides inormation on the size o re detectableat various distances.
The ame detectors can also be ceiling mounted, positionedabove the anticipated ame source or at the centre o thearea to be protected, perpendicular to the oor below. I thedetector cannot see the whole o the area to be protected,
one or more additional detectors may be required. Reer to thesectional view drawing to establish the detector perormance.
The area o detection is dependent on the detectors heightabove the likely source o ame. The detector has a 9 conicaleld o view or 45 either side o the viewing axis centreline. The maximum ceiling height is 2m. I the detector isperpendicular to oor and at a height o 1m then the detectorwill view a circular oor area below with a 1m radius (2mdiameter circle).

Orbis MarineOptical Smoke Detector
ORB-OP 42001-MAR
Orbis Marine Optical Smoke Detector
ORB-OP-42003-MAR
Orbis Marine Optical Smoke Detector with ashing LED
Operating principles
Optical Smoke Detectors have always been recognised as gooddetectors or general use. They are regarded as particularlysuitable or smouldering res and escape routes.
The perormance o Orbis Marine optical detectors is good inblack as well as in white smoke. In this respect Orbis is dierentrom traditional optical smoke detectors which perorm arbetter in white smoke than in black.
Orbis Marine optical detectors are also designed to reducesignicantly the incidence o alse alarms through over-sensitivity to transient phenomena.
Orbis optical detectors are recommended or use as generalpurpose smoke detectors or early warning o re in most areas.
Orbis Marine Optical Smoke Detector
The sensing technology in the Orbis Marine optical smokedetector is signicantly dierent in design rom previous opticaldetectors. A ull description is given in the section How doOrbis Marine optical smoke detectors work? but the advantageso this system and its associated algorithms are:
improvedsensitivitytoblacksmoke
compensationforslowchangesinsensitivity
extraconrmationofsmokebeforethealarmsignalgiven
The algorithms are used to veriy signals rom the sensingchamber, to lter out transients and to decide when the
detector should change to the alarm state.All this combines to increase detection reliability and reducealse alarms.
How does the Orbis Marine opticaldetector work?
Orbis operates on the well established light scatter principle.The remarkable optical design o the Orbis Marine opticalsmoke detector allows it to respond to a wide spectrum o res.
The sensing chamber contains an optical sensor which
measures back-scattered light as well as the more usualorward-scattered light. Sensitivity to black smoke is greatlyimproved.
The detector is calibrated so that Orbis is highly reliable indetecting res but is much less likely to generate alse alarmsthan earlier smoke detectors.
The stability o the detectorhigh reliability, low alse alarmrateis urther increased by the use o algorithms to decidewhen the detector should change to the alarm state. Thisremoves the likelihood o a detector producing an alarm as aresult o smoke rom smoking materials or rom another non-re source.

Orbis Marine Multisensor Smoke Detector
ORB-OH-43003-MAR
Orbis Marine Multisensor Smoke Detector with ashing LED
Where to use Multisensor SmokeDetectors
Multisensor Smoke Detectors are recognised as gooddetectors or general use but are additionally more sensitiveto ast burning, aming res including liquid res thanoptical detectors.
They can be readily used instead o optical smoke detectorsbut should be used as the detector o choice or areas wherethe re risk is likely to include heat at an early stage in thedevelopment o the re.
As with Orbis Marine optical smoke detectors the increasedreliability o detection is combined with high immunity toalse alarms.
The Obis Marine multisensor smoke detector has two sensors,one or smoke, one or heat and the alarm decision is derivedrom either sensor or a combination o both. The multisensor is
a development o the Orbis Marine optical detector describedin the previous chapter and goes urther in its capabilities ore detection.
The optical sensor is identical to the one in the Orbis opticaldetector. Its sensitivity is, however, inuenced by a heat sensingelement which makes the detector more responsive to ast-burning, aming res.

Orbis Marine Heat Detector
The Orbis range incorporates seven heat detector classes tosuit a wide variety o operating conditions in which smokedetectors are unsuitable.
The European standard EN54-5:21 classies heat detectorsaccording to the highest ambient temperature in which theycan saely be used without risk o alse alarm. The classes areidentied by the letters A to G. (Class A is subdivided into A1and A2.) In addition to the basic classication, detectors may beidentied by a sux to show that they are rate-o-rise (sux R)or xed temperature (sux S) types.
All heat detectors in the Orbis range are tested as static orrate-o-rise detectors and are classied as A1R, A1S, A2S, BR, BS,CR and CS.
Choosing the correctclass o Heat Detector
Heat detectors have a wide range o response characteristicsand the choice o the right type or a particular application maynot always seem straightorward. It is helpul to understand theway that heat detectors are classied as explained earlier andto memorise a simple rule: use the most sensitive heat detectoravailable consistent with avoiding alse alarms.
In the case o heat detectors it may be necessary to take anheuristic approach, ie, trial and error, until the best solution ora particular site has been ound. The owchart (Fig 1) willassist in choosing the right class o heat detector.
I the re detection system is being designed to comply withBS 58391: 22 heat detectors should be installed at heightso less than 12 metres with the exception o class A1 detectors,which can be installed at heights up to 13.5 metres.
How do Orbis MarineHeat Detectors work?
Orbis heat detectors have an open-web casing which allowsair to ow reely across a thermistor which measures the airtemperature every 2 seconds. A microprocessor stores thetemperatures and compares them with pre-set values todetermine whether a xed upper limit the alarm level hasbeen reached.
In the case o rate-o-rise detectors the microprocessor usesalgorithms to determine how ast the temperature is increasing.
Static heat detectors respond only when a xed temperaturehas been reached. Rate-o-rise detectors also have a xed upperlimit but they also measure the rate o increase in temperature.A re might thus be detected at an earlier stage than with astatic detector so that a rate-o-rise detector is to be preerredto a static heat detector unless sharp increases o heat arepart o the normal environment in the area protected by theheat detector.
Where to use Heat Detectors
Heat detectors are used in applications where smoke detectorsare unsuitable. Smoke detectors are used wherever possiblesince smoke detection provides earlier warning o re thanheat detection.
Heat detectors should be used i there is a danger o nuisancealarms rom smoke detectors.

ORB-MB-00001-MAR
Orbis Marine TimeSaver Base
Installing Orbis
Orbis has been designed to make installation ast and simple.Fig 2 shows the TimeSaver mounting base as it is seen rom theinstallers point o view.
The E-Z t xing holes are shaped to allow a simple three-stepmounting procedure: Fittwoscrewstothemountingboxorsurface PlacetheOrbisbaseoverthescrewsandslidehome Tightenthescrews
The base oers two xing centres at 51 and 6mm.A guide on the base interior indicates the length o cable to bestripped. Five terminals are provided or the cables, our beinggrouped together or ease o termination.
The terminals are: positiveIN positiveOUT negativeINandOUT(commonterminal) remoteLEDnegativeconnection functionalearth(screen)
The terminal screws are captive screws and will not all out othe terminals. The base is supplied with the screws unscrewed
in order to avoid unnecessary work or the installer.
The end-o-line resistor or active device should be connectedbetween the OUT+ and COM terminals.
I it is required that all detectors be tted with their LEDs acingthe same direction the bases must be tted to the ceilingobserving the marking on the exterior which indicates the
position o the LED.
The bases may be connected as shown in Fig 1where remoteLEDs, i required, are connected to the associated base.
Fig 3shows how to connect one remote LED to more than onebase so that an alarm in any o the detectors connected willswitch the remote LED.
In many installations bases with diodes are specied in orderthat an active end-o-line device may be tted. Diode basesare marked OD. Loop continuity testing is acilitated as there isa continuity device in the base. The continuity device enablespower to pass through every base in a loop to ensure that each
is connected correctly.Once a detector is tted to the base the continuity device isautomatically locked permanently open so that the powerows through the detectors.
Fitting Orbis Detector Heads
When the bases have been installed and the system wiringtested, the detector circuits can be populated.
Two methods are suggested:
1. Apply power and t the detectors one by one, starting at
the base nearest the panel and working towards the endo the circuit. As each detector is powered up it will enterStartUp and ash red (see next page or a ull descriptiono this eature). I the LED does not ash, check the wiringpolarity on the base and ensure there is power acrossIN+ and COM. I the LED is ashing yellow the detectoris not operating correctly and may require maintenanceor replacing (see DirtAlert and SensAlert and the sectionMaintenance and servicing in the Orbis product guide)
2. Fit all detectors to the circuit, apply power and checkdetectors by observing the LED status o each device. TheStartUp eature lasts or 4 minutes so it may be necessaryto reset or de-power the circuit to allow all detectors to beobserved. The LED status is the same as method 1
