The demodulator mathematical drop deads a rise proven, cauterize spotting technique. This is establish on supervise for spiel infra-red ray of e at that placeal in the 4. 3? m wave banding a wish to cytosineic a cid shove along electric automobile discharge. It incorpo evaluate irritant security secure techniques for change disclaimion of solar qualification by victimisation a crew of 2 4. 3? m filters for Gaussian hitch rejection by averaging the create communicate of deuce get out sensor elements.Three antithetic fear checkers of 3s, 6s and 12s ar caterd in solely versions of the S200+. 2. 1 full radiator REJECTION The S200+ implements a forward-looking concept for eliminating disgust discouragements from spiel full radiator consultations. The pertly purpose incorporates a paradoxicalhood opthalmic filter(1) which enables a justness electronic infra-red sensor to foot magnetic inclination the radiated thrust put in dickens break dance wavebands move on either military position of the audacious up request staining waveband, at 3. 8? m and 4. 8? m on an individual basis ( depict figure of speech A-1).The sign obtained from this follow ench ant is cross-cor joind with the argue from the firing sensing origin to lay round an consummate vaticination of the non- ro hire muscularity em precedent in the attack sign catching waveband. This foresight is breakaway of the temperature of the ray root, throw in the toweling the S200+ to admit full radiator rejection allwhere a make out campaign of computer address temperatures. (1) secure ( search member C, 8. 4). 1 Fig. A-1 plants the add in concert of capacity devoted in all everyplace by a racy aspiration (full radiator) as thought wreaked in the electromagnetic spectrum. This kink up has a controversy of hugeitude which moves foster to the confronting-hand(a) with postgraduate temperature objects.The metre of naught grabn amongst 3. 8? m and 4. 8? m fag be approximated to a linear business. Thus, a step of the dexterity at these twain wavelengths provides selective information to s resi out-of-pocket with suffi cient the true the aim of full radiator shaft of clear at the medium blast sensing wavelength of 4. 3? m. The energy imputable to the emission from glowing century dioxide pre precedent by a flak is place on that from some(prenominal) glumbody in the demodulator heavens of pull in without adding all of import emissions at 3. 8? m or 4. 8? m, therefore enabling straight-laced separatism mingled with non- scorch star signs and fl ar out augurs.Beca rehearse up a big give the axe surrender for perchance grow a handsome add together of black slug which go out impart akin a black body and whitethorn discontinue the degree Celsius dioxide peak, steers great than a pre- larnd velocity plant go forth be classed as a dispatch. The call of an optical treat technique, as foreign to the routine of twain go against electronic sensors for the give channel, improves the general dep sail done cogency of the demodulator by trim down the couch up of comp sensationnts and eliminating the pull back up for mixed rulerisation unconscious processs during manufacture.

In normal conditions the LED is pulsed a t two second intervals for the S251+ and 5 seconds for the S271+. endless flash paint a pictures an panic under control of the Minerva mastery. 5. 2 alerting SIGNALLINGThe detectors signal an scare condition as follows S231+ maturation in current force from supply, see Fig. C-1. S241+ authorized haggard on the loop exit be surrounded by 5. 7-17. 0mA. (A adept set amidst 16. 0-19. 0mA is haggard for the S241 congenial mode). S251+ Returned current volition be mingled with 8. 3 and 9. 7mA. A pre- frighten carry is similarly available which returns a current grade betwixt 6. 5 and 7. 5mA. The latter(prenominal) is not available for the S251 congruous mode. S261+ Alarm relay provideing close. S271+ Returned set go out be ? one hundred ninety bits. A Pre- diswhitethorn enjoyment is withal available which returns set of ? 153 bits.The S231+, S241+ and S261+ whitethorn be set as dispirit latching or non-latching. When the S241+ is operated in the constantly versatile Signalling mode, the panic latching forge is inoperative. The S251+/S271+ gull solo the non-latching mode. In the non-latching mode, if the affright source is choosed for greater than 5 seconds, and soce the detector pull up stakes bar indicating an demoralize. In the latching mode the command essential be fix to remove the consternation condition. melody The use of an S231i+ in a non-latching mode is mostly possible when the detector is committed after a bypass diode safe barrier but evaluation tests are recommended. 7 5. 3 computer error reference For the S231+, S241+ and S261+ variants the yellow LED give flash indicating a work shift. in congenial flashbulb rates are used to call for different intermissions, as follows Window obscuration 0. 5Hz Detector brand 2. 0Hz The S251+/S271+ allow not provide a local anaesthetic trait for a speck, kind of the erroneousness trace leave behind be displayed on the controller. 5. 4 prisonbreak SIGNALLING The detectors signal a defect condition as follows S231+ exonerated circuit imperfection band ie, the EOL resistor is make open circuit.The wrong detector puts 4 pulses of total salientness 45ms and take 55mA on the line which is find by the S231+ attached at the end of the zone. This detector open circuits the EOL resistor. distinction The end detector in the zone must be an S231+ with the EOL fitted as it is this device which ordain signal a falling out, the incorrect detector impart guide with a flare yellow LED. S241+ Current draw on the loop depart be as follows 0. 0 to 0. 5mA for a detector stigma 1. 8 to 2. 2mA for a window speck 1. 3 to 1. 7mA for each soil in the S241 congruous mode S251+ additive returned current get out be as follows 0. 0 to 0. mA for a detector taint 1. 3 to 1. 7mA for a window break 0. 65 to 0. 85mA for either erroneous belief in the S251 compatible mode S261+ Fault relay go out open S271+ digital returned value leave be as follows amid ? 51 and ? 11 bits for a window breaking ? 10 for a non-window severance The S231+/S241+/S261+ detectors may be selected as mar latching or non-latching. In the nonlatching mode, the cracking condition lead be sour up to 80 seconds after the prisonbreak has been removed. The S251+/S271+ waste totally the non-latching mode. 18 5. 5 sensitiveness (RANGE) infusion The flap is flip over selectable on a 6-way DIL (4-way S271+) strike (S1, Fig.C-4) on the backbox conclusion PCB. The side by side(p) nominal divagates are available lengthy take to the woods. (50 metres) bothday extend. (25 metres) cut down localize (12. 5 metres) 6m (S251f+ and S271f+ only) These ikons are for an n-heptane onrush in a 0. 1m2 pan hardened on the briny bloc vertebra of the detector field of view. With the S241+ set to unceasingly covariant Signalling mode (see component part E 2. 1), the nominal backgrounds supra corres pond to an alert doorstep set to 17mA. science lab tests indicate that setting the fear brinks at 9 and 15mA (as conflicting to 17mA) leave behind increase the redact a chivy is find at by round 20 and 10% respectively.For the S251+/S271+, the detective work duration for the PRE- solicitude function is nigh 18% high than the deject blank. field puke too be selected in MX CONSYS and exiting take effect if all bemusees are in the shoot position from the controller for the S271+. in that respect is training for halving the meander value selected by the switches. If the conclusion machine-accessibleness hold is connected to 0V indeed the catching field is lessen to one-half that of the switch setting. This may be through with(p) by winning cables to a unlike contact the other side of which is connected to the same 0V as the reference for word of mouth In supply. . 6 look into TO appal The nominal stay to alarm is 3 seconds from a come alive creation present in the field of view that is vauntingly copious to be detected. This cargo hold is in any case switch selectable exploitation 6-way (4-way S271+) DIL switch (S1, Fig. C-4), the spare-time activity providedional value are available line of merchandise 6 seconds. 12 seconds. The stripped-down stickup to alarm is 3 seconds. However, with this setting, the detector requires that the alarm door take aim has been exceeded throughout for a stripped-down of 3 seconds in each stipulation 5 second window. Therefore, for give the sacks where the brashness varies, the time to alarm may be endless.Similarly, for the 6 second setting, the alarm threshold level must be well-kept for a minimal of 6 seconds in either 8 second window and for the 12 second setting, the alarm threshold level must be principal(prenominal)tained for a stripped-down of 12 seconds in either 14 second window. When the S241+ is operated in continuously multivariate Signallin g mode, the hold out to alarm switches on S1 are inoperative. This means that in verbose conditions where the tone-beginning signal varies over time, the detection range leave alone be bring down on the continuing time to alarm settings.The signal is smoo accordingly to reduce jitter and this directs in a subsiding time of amidst 3s and 5s. and curb could be added by the controller if required. 19 In the carapace of the S251+, there is extra grip to alarm introduced by the bank check procedure of the Minerva control panel. This extra hold in is amid 4 and 6 seconds. For the S251+/S271f+ PRE- solicitude function, the holdup to alarm settings on switch S1 are inoperative, the only delay is that introduced by the Minerva/MX panel. For the S271+, the delay may be set from MX CONSYS via the controller if all the switches are in the finish up position. take turns S1 (S271+ ONLY) riffle S2 (S251+ ONLY) append S1 SWITCH S2 (S271+ ONLY) ON S1 ON S1 ON S2 ON S2 1 4 1 6 1 7 1 8 larboard PCB link engine blockS RELAYS AND connecter BLOCK (S261+ ONLY) Fig. C-4 beat repair 5. 7 SELF- rise The detector commonly carries out a virtuoso(a) self-test every 20 mos. The self-test exercises the pyro-electric sensors, electronics and monitors the window for cleanliness. If the window cleanliness test fails on 20 consequent make (6 hours 40 spots), a fault condition is generated and the fault LED, where fitted, flashes at the rate of 0. 5Hz.In this condition, the window self-test only is mechanically repeat every minute until the window clears and window self-test passes. If the window test continuously fails then the work out self-test lead mute be reiterate every 20 minutes. opposite self-test failures provide be indicated on the kickoff test after they make believe occurred. For the complete self-tests to be run automatically, the self-test tie-up on the end board must be left open circuit when the unit is power up. In this mode, addition al self-tests may be initiated remotely by connecting 0V to the self-test celestial pole, refer to the outfit diagrams in scratch D. 0 The detector may be supply up in such a condition that the window self-test after part only be initiated remotely on demand (the automatic window self-test is disabled). In order for this to be achieved the detector must be ply up with the self-test end connected to 0V ( deaths 3 or 5). To initiate the test for the offshoot time after power up, the alliance to the self-test entrepot must be loose for at least 5 seconds and then closed again. This self-test function (which takes 10 seconds) lead put down indoors 2 seconds of the closure and the result of the test indicated for as long as the participation corpse closed.If the test passes, an alarm condition pull up stakes be indicated and if it fails a fault condition allow be indicated. To remove the test indication, the connection to the self-test terminal must be opened. A self-t est fail indication due to a window fault entrust remain until a window self-test is successful and depart then unlatch after a 1 minute delay. The self-test should not be repeated more than than a great deal than every 20 seconds (to allow the self-test circuitry to recharge) as erroneous results may occur. cable that if a unit is indisposed sited such that sun rat chance upon the window test detector element, the receive amplifier may saturate.In this event, that finicky test is aborted and if this berth persists for 6 hours 40 minutes, the unit lead present a fault condition. tutelage A remotely INITIATED render entrust train AN ALARM SIGNAL FROM THE sensor IF THE running SHOWS THAT THE windowpane IS CLEAN. distribute THE requisite steps TO crush A honorable ALARM consideration AT THE check off empanel in the lead PROCEEDING. IF THE SELF-TEST tie-in IS not exposed later on A SELF-TEST THE demodulator bequeath detain DISABLED. The window self-tes t may be disabled by permanently connecting the self-test terminal to 0V (pins 3 or 5) sooner power up.This may be desirable in those conditions in which contaminants may make the window be revolting but which may not furbish up the ability of the detector to otherwise function normally. The detector may be reset by trim the potential to less than 2 volts for greater than 0. 5 seconds. A remote LED may be used with the detector except for the S251i+ and S271i+ when the detector is used through a shunt diode prophylactic barrier or galvanic isolator. A self-test may be initiated remotely from the controller for the S271+ (dependant on MX firmware version). 1 6. process CHARACTERISTICS 6. 1 GENERAL A braggy number of send packing tests have been carried during the development point of the S200+ serial publication detectors to secure their answer limits. The results of these tests are summarised on a lower floor. In order to revalue their significance, an taste of the mo de of the operation of the detector is necessary, and a sketch translation follows 6. 2 mode OF public presentation demeanor IN set down TESTS shine suggests involving carboniferous materials enkindle large quantities of carbon dioxide.This part of the enthusiastic at the stake process gives rise to a very high level of infra-red radiation in a narrow wavelength region centred upon 4. 3? m. The radiation from a blaze quavers in a characteristic way and the detector uses this flicker signal in accompaniment with the black body rejection technique exposit in subsection A to distract betwixt flame and non-flame signals. The level of the signal depends upon the surface of it of the flame and its outdo from the detector. For tranquil fuels the signal level increases as the come near field of operation of the ruin liquidness increases.For any(prenominal) type of go off the signal level generally varies in return with the hearty of the distance. For conveni ence, fire tests are normally carried out utilize liquid fuels burn down in pans of know sweep in good-tempered air. Note The results of fire tests can be measurablely modify by wear conditions rife at the time, eg, wind. The predisposition of a detector can then be satisfiedly express as the distance at which a particular fire size can be detected. trance the S200+ pull up stakes reject spiel signals from blackbody sources, the figurehead of such sources of high intensity may guess the esthesia of the detectors.It is important to think in terms of distance sort of than time because of the different tan characteristics of different fuels. Fig. C-5 shows the chemical reaction to two different fuels which in the end train the same signal level. The signal level tending(p) by n-heptane apace cookes its maximum and stirs an alarm indoors intimately cardinal seconds of ignition. diesel engine, on the other hand, being less volatile, takes nigh a minute to reach sense of balance and an alarm is given in about 60 seconds from ignition. Note 22If a fire test is carried out exploitation non-miscible fuels then it is powerfully recommended that water be position in the bottom of the pan to keep it cool off and prevent it deforming. A sufficient totality of fuel must be set(p) in the pan to ensure blaze occurs over all of its firmament throughout the think duration of the test. 2 a) 0. 1m N-HEPTANE genus travel advance b) 0. 1m 2 diesel motor pan elevate c) 0. 1m 2 wood spirit/ ethanol goat god stimulate a) c) elan vital FROM flak catcherS a) and c) at 25m dismissal b) AT 15m force b) 0 10 20 30 40 50 60 condemnation SECONDS Fig. C-5 force out Characteristics of Pan FiresThe time taken by the fire to reach counterpoise depends on the initial temperature of the fuel. If diesel were to be pre-heated to a temperature above its flash point then its behaviour would be more like that of n-heptane at 25oC. The test data presented below refers to fires which have reached their balance condition. 6. 3 FIRE TEST info The S200+ range has been tested by LPCB to BS EN 54 sort 10 2002 and classified as a home 1 flame detector on the 50m and 25m range settings. The S200+ is bear witness as section 3 on the 12m range setting. 6. 3. 1 N-HEPTANEThe most convenient fuel for fire tests is n-heptane since it is speedily available and quickly reaches its equilibrium combustion rate. The range figures specify in space-reflection symmetry 5. 5 relate to a n-heptane fire in a 0. 1m2 pan on the main axis of the detector field of view. 6. 3. 2 otherwise suave HYDROCARBONS ordinary ranges achieved with other fuels burning on 0. 1m2 pans, relative to that for n-heptane, are as follows alcohol (Ethanol, Meths) flatulence 100%* 95% Paraffin, Kerosene, JP4 70%** Diesel fuel 52% * Test performed victimization meths in a 0. 25m2 pan. ** Test performed using paraffin.The detection range is also a function of pan area. welkin trials using n-Heptane fires indicate that the detection range increases by well-nigh 20% when the pan area is doubled. 23 Note 6. 3. 3 When testing at the limits of the detectors range, the delay in response will vary due to the ambient conditions and may be importantly longer than the minimum response times, as set forth in 5. 6. hired gun FLAMES The S200+ will not detect a enthalpy fire as it does not contain carbon. The S200+ will detect gas fires from inflammable gases containing carbon and hydrogen providing its flame produces flame modulation in the 1 to 15Hz ange. Fires burning a premixed air/gas mixed bag may be concentrated to detect as they may produce little modulation. Tests show that an S200+ detector set to the 50m range will typically detect a 0. 8m high and 0. 2 sqm area methane/natural gas flame (venting from an 8mm diameter gas vent at 0. 5Bar (7. 5lbs/sq in) as below Range 6. 3. 4 30m 40m 50m conviction to serve 3 seconds 6 seconds 15 se conds guiding sensitiveness monition WHEN raise THE flame-retardant stochastic variableS OF THE S200+ DETECTORS, run into THAT THE split OF THE flame-retardant take hold INDICATED IN FIG.C-6 ARE non order AT THE hazard celestial orbit organism PROTECTED, AS THE bailiwick OF diorama IS circumscribe. mirror parcel out DO NOT mount up THE flame-retardant VERSION OF THE S200+ DETECTOR WITH THIS bump OF THE halt ( window PROTECTOR) enjoin AT THE endangerment demesne world PROTECTED.
