RK109DT RK109DTX 微波红外双鉴入侵探测器安装说明书

RK109DT/RK109DTX 微波/红外双鉴入侵探测器安装说明书1.RK109DTX （微波/被动红外/防下潜型）及RK109DT （微波/被动红外型）是微处理器控制的双技术入侵探测器。

红外与微波技术相结合，互相补充以确保最可靠的探测效果并防止误报。

实际运动识别运算法则的出现，使得RK109DT(X)系列产品优于其它的双鉴探测器。

这种先进的运动分析法使得RK109DT(X)能够将人体的实际运动因素与其它经常导致误报的干扰因素区分开来。

RK109DT(X)的另一独特优点在于其微波运动模拟电路,它可以模拟人体在微波区域移动产生的效果。

这种模拟程序定期运行以供自检，监督并确保微波探测的正常工作。

此外，还运用短时间热脉冲定期对热电传感器及其电路进行检测。

如果它们不能正常工作，会触发出错报警。

为了弥补前透镜的探测范围，RK109DT(X)还在正面机盖的底部安装了一个向下的透镜。

此透镜用于防止从探测器的下面非法接触探测器。

must be made for adjusting to indicate true zero at zero load.There shall be provided a maximum load indicator that at all times until reset will indicate within 1%system accuracy the maximum load applied to the specimen.N OTE 2—As close as can be read is considered 1⁄50in.or [0.5mm]along the arc described by the end of the pointer.Also,one half of the scale interval is about as close as can reasonably be read when the spacing on the load indicating mechanism is between 1⁄25in.or [1mm]and 1⁄16in.or [1.6mm].When the spacing is between 1⁄16in.or [1.6mm]and 1⁄8in.or [3.2mm],one third of the scale interval can be read with reasonable certainty.When the spacing is 1⁄8in.or [3.2mm]or more,one fourth of the scale interval can be read with reasonable certainty.5.9.2The upper bearing shall be a spherically seated,hardened metal block ﬁrmly attached at the center of the upper head of the machine.The center of the sphere shall lie at the center of the surface of the block in contact with the specimen.The block shall be closely held in its spherical seat,but shall be free to tilt in any direction.The diagonal or diameter (Note 3)of the bearing surface shall be only slightly greater than the diagonal of the face of the 2-in.or [50-mm]cube in order to facilitate accurate centering of the specimen.A hardened metal bearing block shall be used beneath the specimen to minimize wear of the lower platen of the machine.The bearing block surfaces intended for contact with the specimen shall have a Rockwell hardness number not less than 60HRC.These surfaces shall not depart from plane surfaces by more than 0.0005in.or [0.013mm]when the blocks are new and shall be maintained within a permissible variation of 0.001in.or [0.025mm].N OTE 3—A diameter of 31⁄8in.or [79.4mm],is satisfactory,provided that the lower bearing block has a diameter slightly greater than the diagonal of the face of the 2-in.or [50-mm]cube but not more than 2.9in.or [74mm],and is centered with respect to the upper bearing block andTABLE 1Permissible Variations of Specimen Molds2-in.Cube Molds[50-mm]Cube MoldsParameterNew In Use NewIn UsePlaneness of

Sand:6.1.1The sand(Note4)used for making test specimens shall be natural silica sand conforming to the requirements for graded standard sand in Speciﬁcation C778.N OTE4—Segregation of Graded Sand—The graded standard sand should be handled in such a manner as to prevent segregation,since variations in the grading of the sand cause variations in the consistency of the mortar.In emptying bins or sacks,care should be exercised to prevent the formation of mounds of sand or craters in the sand,down the slopes of which the coarser particles will roll.Bins should be of sufficient size to permit these precautions.Devices for drawing the sand from bins by gravity should not be used.7.Temperature and Humidity7.1Temperature—The temperature of the air in the vicinity of the mixing slab,the dry materials,molds,base plates,and mixing bowl,shall be maintained between73.565.5°F or [23.063.0°C].The temperature of the mixing water,moist closet or moist room,and water in the storage tank shall be set at73.563.5°F or[2362°C].7.2Humidity—The relative humidity of the laboratory shall be not less than50%.The moist closet or moist room shall conform to the requirements of Speciﬁcation C511.8.Test Specimens8.1Make two or three specimens from a batch of mortar for each period of test or test age.9.Preparation of Specimen Molds9.1Apply a thin coating of release agent to the interior faces of the mold and non-absorptive base plates.Apply oils and greases using an impregnated cloth or other suitable means. Wipe the mold faces and the base plate with a cloth as necessary to remove any excess release agent and to achieve a thin,even coating on the interior surfaces.When using an aerosol lubricant,spray the release agent directly onto the mold faces and base plate from a distance of6to8in.or[150to200 mm]to achieve complete coverage.After spraying,wipe the surface with a cloth as necessary to remove any excess aerosol lubricant.The residue coating should be just sufficient to allow a distinctﬁnger print to remain following lightﬁnger pressure (Note5).9.2Seal the surfaces where the halves of the mold join by applying a coating of light cup grease such as petrolatum.The amount should be sufficient to extrude slightly when the two halves are tightened together.Remove any excess grease witha cloth.9.3After placing the mold on its base plate(and attaching, if clamp-type)carefully remove with a dry cloth any excess oil or grease from the surface of the mold and the base plate to which watertight sealant is to be applied.As a sealant,use paraffin,microcrystalline wax,or a mixture of three parts paraffin toﬁve parts rosin by mass.Liquify the sealant by heating between230and248°F or[110and120°C].Effect a watertight seal by applying the liqueﬁed sealant at the outside contact lines between the mold and its base plate.N OTE5—Because aerosol lubricants evaporate,molds should be checked for a sufficient coating of lubricant immediately prior to use.If an extended period of time has elapsed since treatment,retreatment may be necessary.N OTE6—Watertight Molds—The mixture of paraffin and rosin speciﬁed for sealing the joints between molds and base plates may be found difficult to remove when molds are being e of straight paraffin is permissible if a watertight joint is secured,but due to the low strength of paraffin it should be used only when the mold is not held to the base plate by the paraffin alone.A watertight joint may be secured with paraffin alone by slightly warming the mold and base plate before brushing the joint. Molds so treated should be allowed to return to the speciﬁed temperature before use.10.Procedure10.1Composition of Mortars:10.1.1The proportions of materials for the standard mortar shall be one part of cement to2.75parts of graded standard sand by e a water-cement ratio of0.485for all portland cements and0.460for all air-entraining portland cements.The amount of mixing water for other than portland and air-entraining portland cements shall be such as to produce aﬂow of11065as determined in accordance with10.3and shall be expressed as weight percent of cement.10.1.2The quantities of materials to be mixed at one time in the batch of mortar for making six and nine test specimens shall be as follows:Number of Specimens69 Cement,gSand,gWater,mL50013757402035Portland(0.485)Air-entraining portland(0.460)242230359340 Other(toﬂow of11065)...... 10.2Preparation of Mortar:10.2.1Mechanically mix in accordance with the procedure given in Practice C305.10.3Determination of Flow:10.3.1Determineﬂow in accordance with procedure given in Test Method C1437.10.3.2For portland and air-entraining portland cements, merely record theﬂow.10.3.3In the case of cements other than portland or air-entraining portland cements,make trial mortars with varying percentages of water until the speciﬁedﬂow is obtained.Make each trial with fresh mortar.10.4Molding Test Specimens:10.4.1Immediately following completion of theﬂow test, return the mortar from theﬂow table to the mixing bowl. Quickly scrape the bowl sides and transfer into the batch the mortar that may have collected on the side of the bowl and then remix the entire batch15s at medium speed.Upon completion of mixing,the mixing paddle shall be shaken to remove excess mortar into the mixing bowl.10.4.2When a duplicate batch is to be made immediately for additional specimens,theﬂow test may be omitted and the mortar allowed to stand in the mixing bowl90s without covering.During the last15s of this interval,quickly scrape the bowl sides and transfer into the batch the mortar that may have collected on the side of the bowl.Then remix for15s at mediumspeed.10.4.3Start molding the specimens within a total elapsed time of not more than 2min and 30s after completion of the original mixing of the mortar batch.Place a layer of mortar about 1in.or [25mm](approximately one half of the depth of the mold)in all of the cube compartments.Tamp the mortar in each cube compartment 32times in about 10s in 4rounds,each round to be at right angles to the other and consisting of eight adjoining strokes over the surface of the specimen,as illustrated in Fig. 1.The tamping pressure shall be just sufficient to ensure uniform ﬁlling of the molds.The 4rounds of tamping (32strokes)of the mortar shall be completed in one cube before going to the next.When the tamping of the ﬁrst layer in all of the cube compartments is completed,ﬁll the compartments with the remaining mortar and then tamp as speciﬁed for the ﬁrst layer.During tamping of the second layer,bring in the mortar forced out onto the tops of the molds after each round of tamping by means of the gloved ﬁngers and the tamper upon completion of each round and before starting the next round of tamping.On completion of the tamping,the tops of all cubes should extend slightly above the tops of the molds.Bring in the mortar that has been forced out onto the tops of the molds with a trowel and smooth off the cubes by drawing the ﬂat side of the trowel (with the leading edge slightly raised)once across the top of each cube at right angles to the length of the mold.Then,for the purpose of leveling the mortar and making the mortar that protrudes above the top of the mold of more uniform thickness,draw the ﬂat side of the trowel (with the leading edge slightly raised)lightly once along the length of the mold.Cut off the mortar to a plane surface ﬂush with the top of the mold by drawing the straight edge of the trowel (held nearly perpendicular to the mold)with a sawing motion over the length of the mold.10.5Storage of Test Specimens —Immediately upon completion of molding,place the test specimens in the moist closet or moist room.Keep all test specimens,immediately after molding,in the molds on the base plates in the moist closet or moist room from 20to 72h with their upper surfaces exposed to the moist air but protected from dripping water.If the specimens are removed from the molds before 24h,keep them on the shelves of the moist closet or moist room until they are 24-h old,and then immerse the specimens,except those for the 24-h test,in saturated lime water in storage tanks con-structed of noncorroding materials.Keep the storage water clean by changing as required.10.6Determination of Compressive Strength :10.6.1Test the specimens immediately after their removal from the moist closet in the case of 24-h specimens,and from storage water in the case of all other specimens.All testspecimens for a given test age shall be broken within the permissible tolerance prescribed as follows:Test Age Permissible Tolerance24h 61⁄2h 3days 61h 7days 63h 28days612hIf more than one specimen at a time is removed from the moist closet for the 24-h tests,keep these specimens covered with a damp cloth until time of testing.If more than one specimen at a time is removed from the storage water for testing,keep these specimens in water at a temperature of 73.56 3.5°F or [2362°C]and of sufficient depth to completely immerse each specimen until time of testing.10.6.2Wipe each specimen to a surface-dry condition,and remove any loose sand grains or incrustations from the faces that will be in contact with the bearing blocks of the testing machine.Check these faces by applying a straightedge (Note 7).If there is appreciable curvature,grind the face or faces to plane surfaces or discard the specimen.A periodic check of the cross-sectional area of the specimens should be made.N OTE 7—Specimen Faces—Results much lower than the true strength will be obtained by loading faces of the cube specimen that are not truly plane surfaces.Therefore,it is essential that specimen molds be kept scrupulously clean,as otherwise,large irregularities in the surfaces will occur.Instruments for cleaning molds should always be softer than the metal in the molds to prevent wear.In case grinding specimen faces is necessary,it can be accomplished best by rubbing the specimen on a sheet of ﬁne emery paper or cloth glued to a plane surface,using only a moderate pressure.Such grinding is tedious for more than a few thousandths of an inch (hundredths of a millimetre);where more than this is found necessary,it is recommended that the specimen be discarded.10.6.3Apply the load to specimen faces that were in contact with the true plane surfaces of the mold.Carefully place the specimen in the testing machine below the center of the upper bearing block.Prior to the testing of each cube,it shall be ascertained that the spherically seated block is free to e no cushioning or bedding materials.Bring the spherically seated block into uniform contact with the surface of the specimen.Apply the load rate at a relative rate of movement between the upper and lower platens corresponding to a loading on the specimen with the range of 200to 400lbs/s [900to 1800N/s].Obtain this designated rate of movement of the platen during the ﬁrst half of the anticipated maximum load and make no adjustment in the rate of movement of the platen in the latter half of the loading especially while the cube is yielding before failure.N OTE 8—It is advisable to apply only a very light coating of a good quality,light mineral oil to the spherical seat of the upper platen.11.Calculation11.1Record the total maximum load indicated by the testing machine,and calculate the compressive strength as follows:fm 5P /A(1)where:fm =compressive strength in psi or[MPa],FIG.1Order of Tamping in Molding of TestSpecimensP=total maximum load in lbf or[N],andA=area of loaded surface in2or[mm2].Either2-in.or[50-mm]cube specimens may be used for the determination of compressive strength,whether inch-pound or SI units are used.However,consistent units for load and area must be used to calculate strength in the units selected.If the cross-sectional area of a specimen varies more than1.5%from the nominal,use the actual area for the calculation of the compressive strength.The compressive strength of all accept-able test specimens(see Section12)made from the same sample and tested at the same period shall be averaged and reported to the nearest10psi[0.1MPa].12.Report12.1Report theﬂow to the nearest1%and the water used to the nearest0.1%.Average compressive strength of all specimens from the same sample shall be reported to the nearest10psi[0.1MPa].13.Faulty Specimens and Retests13.1In determining the compressive strength,do not con-sider specimens that are manifestly faulty.13.2The maximum permissible range between specimens from the same mortar batch,at the same test age is8.7%of the average when three cubes represent a test age and7.6%when two cubes represent a test age(Note9).N OTE9—The probability of exceeding these ranges is1in100when the within-batch coefficient of variation is2.1%.The2.1%is an average for laboratories participating in the portland cement and masonry cement reference sample programs of the Cement and Concrete Reference Laboratory.13.3If the range of three specimens exceeds the maximum in13.2,discard the result which differs most from the average and check the range of the remaining two specimens.Make a retest of the sample if less than two specimens remain after disgarding faulty specimens or disgarding tests that fail to comply with the maximum permissible range of two speci-mens.N OTE10—Reliable strength results depend upon careful observance of all of the speciﬁed requirements and procedures.Erratic results at a given test period indicate that some of the requirements and procedures have not been carefully observed;for example,those covering the testing of the specimens as prescribed in10.6.2and10.6.3.Improper centering of specimens resulting in oblique fractures or lateral movement of one of the heads of the testing machine during loading will cause lower strength results.14.Precision and Bias14.1Precision—The precision statements for this test method are listed in Table2and are based on results from the Cement and Concrete Reference Laboratory Reference Sample Program.They are developed from data where a test result is the average of compressive strength tests of three cubes molded from a single batch of mortar and tested at the same age.A signiﬁcant change in precision will not be noted when a test result is the average of two cubes rather than three. 14.2These precision statements are applicable to mortars made with cements mixed,and tested at the ages as noted.The appropriate limits are likely,somewhat larger for tests at younger ages and slightly smaller for tests at older ages. 14.3Bias—The procedure in this test method has no bias because the value of compressive strength is deﬁned in terms of the test method.15.Keywords15.1compressive strength;hydraulic cement mortar;hy-draulic cement

LM109资料

LM109/LM3095-Volt RegulatorGeneral DescriptionThe LM109series are complete 5V regulators fabricated on a single silicon chip.They are designed for local regulation on digital logic cards,eliminating the distribution problems association with single-point regulation.The devices are available in two standard transistor packages.In the solid-kovar TO-5header,it can deliver output currents in ex-cess of 200mA,if adequate heat sinking is provided.With the TO-3power package,the available output current is greater than 1A.The regulators are essentially blowout proof.Current limiting is included to limit the peak output current to a safe value.In addition,thermal shutdown is provided to keep the IC from overheating.If internal dissipation becomes too great,the regulator will shut down to prevent excessive heating.Considerable effort was expended to make these devices easy to use and to minimize the number of external compo-nents.It is not necessary to bypass the output,although thisdoes improve transient response somewhat.Input bypass-ing is needed,however,if the regulator is located very far from the filter capacitor of the power supply.Stability is also achieved by methods that provide very good rejection of load or line transients as are usually seen with TTL logic.Although designed primarily as a fixed-voltage regulator,the output of the LM109series can be set to voltages above 5V,as shown.It is also possible to use the circuits as the control element in precision regulators,taking advantage of the good current-handling capability and the thermal overload protection.Featuresn Specified to be compatible,worst case,with TTL and DTLn Output current in excess of 1An Internal thermal overload protection n No external components requiredSchematic

the LM109to ground with≥0.2µFceramic or solid tantalum capacitor if main filter capaci-tor is more than4inches away.2.Avoid insertion of regulator into“live”socket if inputvoltage is greater than10V.The output will rise to within 2V of the unregulated input if the ground pin does not make contact,possibly damaging the load.The LM109 may also be damaged if a large output capacitor is charged up,then discharged through the internal clamp zener when the ground pin makes contact.3.The output clamp zener is designed to absorb tran-sients only.It will not clamp the output effectively if a fail-ure occurs in the internal power transistor structure.Ze-ner dynamic impedance is≈4Ω.Continuous RMS current into the zener should not exceed0.5A.4.Paralleling of LM109s for higher output current is notrecommended.Current sharing will be almost nonexist-ent,leading to a current limit mode operation for devices with the highest initial output voltage.The current limit devices may also heat up to the thermal shutdown point (≈175˚C).Long term reliability cannot be guaranteed under these conditions.5.Preventing latchoff for loads connected to negativevoltage:If the output of the LM109is pulled negative by a high cur-rent supply so that the output pin is more than0.5V negative with respect to the ground pin,the LM109can latch off.This can be prevented by clamping the ground pin to the output pin with a germanium or Schottky diode as shown.A silicon diode(1N4001)at the output is also needed to keep the positive output from being pulled too far negative.The10Ωresistor will
