3INTRODUCTION_____________________________________________________________Model 380 Outdoor Microwave Transceiver incorporates state-of-the-art technology and innovative electronic circuitryto provide reliable detection in the outdoor environment. A unique continuously variable Range Cutoff (RCO) circuitallows maximum detection range to be established independently of object size, thereby eliminating alarms caused bylarge objects beyond the desired detection range. Model 380 is also equipped with Zero Range Suppression (ZRS)circuitry that reduces sensitivity to small objects very close to the transceiver so that alarms due to rain or vibration areminimized.Model 380 includes synchronization and addressing circuitry that enables simultaneous operation of up to 16 unitswithout mutual interference. The Model 380 is also built with staggered RF frequencies (Channel A and B) to helpminimize mutual interference. Model 380 may be mounted to a variety of posts or wall structures by means of itsuniversal-mounting bracket. A military style multi-pin connector, at the rear of the transceiver housing, permits remotemonitoring and diagnostics of critical system parameters.OPERATION_________________________________________________________________Model 380 includes both transmitter and receiver in a single enclosure. The transmitter radiates microwave energy thatis reflected back into the receiver by objects within the detection zone. The observed detection zone is established bytwo controls - Sensitivity and Range. Figure 1A shows the zone of detection (horizontal pattern) for an upright manwhen Model 380 is mounted 2.5 feet (.75 meters) above smooth earth with its beam oriented parallel to the ground. TheRange control adjusts the maximum range of the system and the Sensitivity control primarily adjusts the width. Figure1B shows the vertical pattern for the same configuration, note that the detection zone does not extend into the small areaimmediately under Model 380.This area varies with the Sensitivity setting as shown in Figure 2. In order to provide uninterrupted detection of a manwalking or crawling on his hands and knees, an additional unit must provide overlap protection such as shown in Figure3. Detection of a man crawling "commando-style" may require additional overlap or special site preparation.Sensitivity should always be adjusted to the absolute lowest setting that will meet site security requirements. Excessivelyhigh sensitivity may cause nuisance alarms from high grass, small birds or windblown debris in the detection zone. Model 380 responds to any motion within the detection zone.Figure 1 - Model 380 Detection PatternSENSITIVITY MINIMUMSENSITIVITY MAXIMUMACTIVEDETECTIONPATTERNCUTOFFRCOCONTINUOUSLYVARIABLE50' MIN 200' MAX(3.4m)(15m) (122m)A) HORIZONTAL PATTERNB) VERTICAL PATTERN15' MAXPATTERNHEIGHT
4THEORY_____________________________________________________________________A microwave transceiver transmits microwave energy into the detection zone, and objects in the zone reflect energyback to its receiver. Whenever an object is moving, the Doppler effect shifts the frequency of its reflection and thetransceiver generates an alarm whenever it detects a frequency shift in the reflected energy. The size of a frequency-shifted reflection that will cause alarms is varied by the Sensitivity control causing the detection zone for any particularobject to vary as shown in Figure 1. Note that Figure 1 applies to an upright walking man. The detection zone for alarge object such as a truck would be larger and for a small object such as a man, crawling would be smaller.In Model 380, the transmitter is periodically turned on and off, but the receiver is turned on only for a short period afterthe transmitter is turned on. Because microwave energy always travels at nearly the speed of light, elapsed time betweentransmission and reception provides an accurate measurement of range (distance) from Model 380 to whatever object isbeing illuminated. By turning the receiver on only during the period corresponding to maximum desired range,reflections from objects beyond this range are ignored, even if the reflections are very large. In Model 380, the rangecontrol determines the time that the receiver observes the reflections and thus sets the maximum (RCO) distance asshown in Figure 1.Reflections from small objects such as raindrops very near the transceiver are frequently as large as reflections from aman in the detection zone. Model 380 overcomes this problem by transmitting two different microwave frequencies onalternate transmitter pulses. Because each object reflects two different frequencies, the receiver can determine thedistance to each object. At zero range (in the vicinity of the radome), the phase difference between the two frequenciesis approximately zero. By combining the two Doppler signals in a difference amplifier, the gain is reduced significantly.In order to insure a continuous perimeter, it is necessary to provide sufficient overlap so that the dead zone immediatelybelow and behind the sensor is protected. Figures 2 and 3 show required overlap information.Figure 2 - Required Overlap vs. SensitivityMIN 1/2 MAXDEAD ZONESENSITIVITYREQUIRED OVERLAP(2.5 foot (0.8m) mounting height)40' (12.2m)30' (9.1m)20' (6.1m)10' (3.0m)5' (1.5m)0'50' (15.2m)MAXIMUM SECURITYMINIMUM SECURITY
5Figure 3 - Overlap of Model 380 Detection ZoneFigure 4 shows a block diagram of Model 380. Logic pulses generated by the synchronization phase-locked loop (PLL)and the associated counter and 4-bit comparator provide the command for turning the transmitter on and off at aprescribed rate, and at one of 16 unique periods of time or addresses. A signal is also derived for switching thetransmitter alternately between the two frequencies required for Zero Range Suppression.The Range control sets the delay generated logic functions initiated by the turn on of the transmitter.The transmitter is a cavity stabilized fundamental GUNN oscillator that provides 32 milliwatts (peak) of microwavepower. Most of the oscillator power is transmitted into space by the parabolic antenna, but a small portion is mixed withthe reflected signal and is coupled to a microwave detector within the antenna assembly. The detector is a Schottkydiode that extracts the Doppler shift frequency from the reflected microwave energy.OVERLAP AREAOverlap Area
6The Doppler signal is amplified and then gated to one of two sample and hold amplifiers. The amplifiers are selected bymeans of S1 and S2 and are switched coincident with the alternate transmitter frequencies. SI and S2 are held closed fora period of time determined by the range cut-off circuit. Range gating is accomplished by turning on the switch at thesame time the transmitter is activated. The switch is then opened at a time selected by the range cut-off circuit so that theinformation entering the receiver due to targets outside the range cut-off are not processed. The sampling capacitorsfollowing the switches hold their charge when the switches are opened. This provides a means for reconstructing eachsignal after it is sampled.At the differential amplifier input, the phase between channels is a function of distance to the target and separation of thetwo transmitter frequencies. Signals arriving from RCO distance are out of phase while signals from zero distance are inphase. Thus, amplifier output is large for signals from RCO distance and small for signals from zero distance.The differential amplifier output is amplified by a factor established by the Sensitivity control and compared withpositive and negative voltage thresholds. Whenever the signal exceeds plus or minus one volt, a pulse is delivered to anintegrator. After a predetermined number of pulses have been stored, the integrator output voltage exceeds alarmthreshold and the alarm relay is de-energized for two seconds.A test function is included in Model 380. When gated on by a +5 to +12 VDC command (at the terminal block), the testfunction provides a phantom signal into the transmitter and receiver circuits to generate an alarm and test the entire 380detection system.Figure 4 - Block Diagram Model 3804 BITCOMPADDRPLLCTRMASTEROUTPUTSLAVEINPUT1.0 uSecAMPAMP+-SENSVLALARMCKTSTHRESHOLDLOW-PASSFILTERRCOTIMINGRANGEFbFaTXOSCVCODRIVERFcFc Fd+-LOCKS1RELAYTB1-6TB1-7TB1-8TB1-4TB1-5N.O.COMN.C.COMN.C.ALARMALARMTB1-10TB1-11TB1-12TB1-13TB1-14++--SUPPLYVCOSUPPLYPOWERTB1-9TB1-1TB1-2P1-APOWERP1-D+-P1-B+9V+5V+7V TESTP1-FP1-CP1-ELEDLEDLEDTAMPERSWITCHTB1-3 N.O.ONESHOTS2VH+5VSYNCON OFF+2LEADINGEDGEDETECTORVHVL
7Model 380 is also equipped with an interference/tamper detection circuit. Should a metal container be placed over thetransceiver in an attempt to reduce the detection zone, the DC amplifier will detect a change in mixer peak output, andafter about 15 seconds an alarm will be generated.The block diagram (see Figure 4) shows location for the various terminals and test points. Terminal block points aredesignated TB while P indicates pin numbers for the military-style MS connector located at the rear of the transceiver.MS connector test points may be conveniently monitored in the field by means of Model RM82 Performance Test Set.SPECIFICATIONS____________________________________________________________Equipment Supplied: Model 380 Outdoor Microwave Transceiver and universal swivel ball mounting bracket.Detection Range: Variable from 50 ft (15m) to 200 ft (61m).

SeeFigure 6. Detection zone for very large objects such as trees or trucks may be larger than the detection zone for man. Figure 6Level hills and ditches so that detection zone is flat to within six inches (15cm). For detection of prone crawling target,detection zone should be flat to within three inches (8cm). Sharp hills or ditches may shadow an intruder. Provide gooddrainage. Large puddles may cause nuisance alarms. Surface of the zone may be any stable, reasonably smooth materialsuch as concrete, asphalt, earth or gravel. Grass or vegetation must be kept cut to maximum of three inches (8cm) high.

9Figure 7Be aware that large fixed objects reflect microwave energy and distort the detection zone. See Figure 8.Figure 8When installing Model 380 inside buildings, do not illuminate fluorescent lights. Flickering lights may cause nuisancealarms. Be aware that detection zone pattern may penetrate windows, thin wooden doors or partition walls.LOCATION OF TRANSCEIVERS_______________________________________________Model 380 is normally mounted about 30 inches (76cm) above ground on a post and pointed parallel to the ground toprovide detection zone of Figure 1.Always locate Model 380 inside a controlled access area to prevent nuisance alarms from random foot traffic, vehiclesor animals. Select locations, which provide protection from accidental damage as well as from tampering. Often simplebumper guards will prevent damage from vehicles. See Figure 9.Normal Detection Pattern Distorted Detection Pattern
10Figure 9When Model 380 is used inside a fence always orient the beam so that the detection zone does not include the fenceitself because the fence may move with high winds and cause nuisance alarms. Note that Model 380's range cutoff(RCO) capability makes possible a variety of locations, but caution must be observed along the sides of the detectionzone to prevent alarms from large moving objects such as trucks which may pass inside the RCO distance. See Figure10.Figure 10RCO DISTANCEBUMPER GUARDSDO DON'T
11MULTIPLE UNIT INSTALLATIONS____________________________________________Two or more Model 380's may be used together or with microwave T/R links such as Southwest Microwavesynchronized Model 300B/310B in order to provide a long interrupted detection zone. The unique multiplex feature ofthe Model 380 allows the sensor to operate with up to 15 additional transceivers with no mutual interference, since onlyone unit is activated at a time. The unit is also built with two (A and B) staggered RF frequencies to help reduce mutualinterference. Figure 11 shows the typical synchronization wiring configuration for the Model 380 transceivers. Any unitmay be selected to be the master clock but only one master is used for 15 slaves. Since all units are synchronized to a 1kHz square wave that is supplied from the master, their turn-on time is controlled by an address code selectable at eachof the units. Table 1 gives the time slots versus address code. Unless there is no danger of interference, all units shouldbe set to different address codes.When interfacing the Model 380 to microwave intrusion links, the unit that has the highest potential to cause mutualinterference is the Model 310B. This is because both units operate at the same K-band frequency. To synchronize theModel 380 with synchronized units of Model 310B you would need to use the Model SMC10 Synchronizer Module toact as the master clock. Contact Southwest Microwave for correct models and additional information.In order to properly terminate the twisted pair synchronization line it is necessary to add a 120 ohm, ¼ watt resistorbetween the (+) and (-) synchronization terminals of the final unit in the chain.When the units are synchronized, the lock LED on all "slave" units will not illuminate. Only the "master" unit will havethe lock LED illuminated.Figure 11MASTER38038038010 SET MASTER UNIT TO ADDRESS CODE 0SET SECOND UNIT TO ADDRESS CODE 1SET THIRD UNIT TO ADDRESS CODE 2#22 or 24 GA.

13Figure 12 C and DMOUNTING__________________________________________________________________Prepare a rigid mounting surface. Do not mount to cyclone fence or any vibrating surface. For post mounting use a 3½inch (9cm) galvanized pipe [outside diameter four inches (10cm)], sunk into concrete base and protruding four feet(1.2m) above ground. See Figure 13.The concrete footer can vary depending on frost line conditions.Model 380 may also be mounted to a rigid wall or on the side of a building using the holes in the mounting plate. It canalso be mounted to unistrut using the holes in the mounting plate. Unistrut will allow for horizontal or verticaladjustments. Additional holes are in the mounting plate for 2.5 and 3.5 inch u-bolts (not provided).Remove Model 380 from its shipping carton. Separate the swivel assembly from its mounting plate by rotating the largenut (1¼ inch, 3.2cm) counterclockwise. Secure the mounting bracket to the post of Figure 13 with U-bolts provided orto alternate mounting surface with appropriate screws or fasteners.Connect the swivel assembly with washers and nuts to the center hub of the Model 380 baseplate. Reconnect the swivelassembly to the mounting plate. Rotate Model 380 so that conduit fitting is pointed straight down, point Model 380toward desired detection zone and tighten the large nut.It is recommended that a 18 inch long, ½ inch flexible conduit be used between the Model 380 conduit fitting and thefixed conduit or junction box in order to provide a means of swiveling the Model 380 transceiver.100'D300BT OR 310BT 300BR OR 310BR380C

15Southwest Microwave recommends two optional power supply combinations. Model PS50 .3 Amp Power Supply withModel BA30 6.5 AH battery will power one Model 380 Transceiver. Model PS50 may be mounted either indoors oroutdoors in a weatherproof enclosure such as Southwest Microwave Model BX15. Model PS40 1.6 Amp Power Supplywith Model BA30 6.5 AH battery will power up to six Model 380 Transceivers (with proper wiring per Figure 15). Model PS40 may be mounted either indoors or outdoors in a weatherproof enclosure such as Southwest MicrowaveModel BX20 or BX35.Figure 14CONNECTIONS______________________________________________________________Caution: Do not apply power until all wire connections have been made. See following instructions. Figure 14 showsphysical locations of sensitivity and RCO adjustments, LED indicators and terminal strip.1) Remove radome of Model 380 Transceiver by removing the six-radome screws.2) Insert power wires, alarm circuit wires, tamper circuit wires and synchronization wires through conduit fitting. Leave enough slack in wires so that transceiver may be tilted after radome is replaced.3) Make connections to the terminal strip according to labeled terminal functions. (See Figure 15.)4) Attach power wires to terminal identified as +12 VDC (Positive) and GND (Negative). Observe polarity.5) For protection against unauthorized openings or tampering, a tamper switch with a separate set of contacts isprovided. Normally open and closed contacts are available at "Tamper Switch" terminal.6) For synchronization, a #22 or #24 gauge twisted shielded pair wire must be connected between the transceivers. One end of the wire is connected to (+) and (-) master synchronization terminals. The other end connects to (+) and(-) slave terminal on the second transceiver. Additional slaves would be daisy chained from (+) and (-) slaveterminal (See Figure 11). The last slave unit must be terminated with a 120 ohm 1/4 watt resistor. Set the units tothe appropriate address code with the master set to zero. Set the Sync Switch to “ON” position on master.POWER LEDLOCK LEDALARM LEDRANGE CUT-OFF ADJUST SENSITIVITY ADJUST(Top Front of Enclosure)ADDRESS SELECTSWITCH, (CAPPED)POWERALARMLOCKADRSFUSE 1ASYNCSWITCHTAMPERSWITCH
167) A test function is included in Model 380. When gated on by a +5 to +12 VDC command (at the terminal block),the test function provides a phantom signal into the transmitter and receiver circuits to generate an alarm and testthe entire 380 detection system.8) After wiring is complete, it is recommended that entry conduit be filled (sealed) with non-corrosive sealant such asDow-Corning #738 RTV. This will prevent moist air in the conduit system from entering Model 380 Transceiver. Non-corrosive RTV is available from electronic supply distributors or from Southwest Microwave, Inc.Figure 15ALIGNMENT AND TEST______________________________________________________Model 380 requires only Southwest Microwave Model RM82 Performance Test Set for on-site alignment.1.0 SINGLE UNIT INSTALLATION1.1 Remove radome.1.2 Remove dust cap from MS connector located on rear of unit.1.3 Connect RM82 Test Meter to MS connector.1.4 Remove cap for access to address switch and set code 0.1.5 Replace cap.1.6 Orient Model 380 in direction of required detection zone and apply power.NOTE: SHIELDED WIRERECOMMENDEDNOTE: After wiring is complete, it is recommended that entry conduit be filled(sealed) with non-corrosive sealant such as Dow Corning #738 RTV.

Reflected signals will cause the meter to swing about this point). An alarmwill occur whenever the meter swings to below 0.2 and above 0.8.1.11 Set alarm selector to Audio and perform a walk test to determine the actual detection pattern.1.12 Adjust the Range control to provide the required maximum range.1.13 Adjust the Sensitivity control clockwise to increase the detection pattern width as desired.1.14 Return the RM82 function switch to the Sensitivity position to be sure that the meter reading remainsstable. Large variations in meter reading can indicate that the sensitivity is set too high, something ismoving or vibrating, or there is interference and may cause nuisance alarms. Recheck the site for movingor vibrating objects within the detection pattern and possible sources for interference.1.15 Replace the radome and repeat the walk test.2.0 MULTIPLE UNIT INSTALLATIONFollow wiring diagram as shown in Figure 11. It is recommended that each sensor be aligned individually. Followthe procedure outlined in section 1.0 except that the address code in step 1.4 should be set at different channels foreach unit. Insure that the lock light is out at each sensor, except the one designated as the master. This indicatesthat the internal oscillator has acquired lock.Note: Voltages at MS connector pins are:PIN VOLTAGE FUNCTIONA10.5-14VDC Input PowerB8.5 VDC ± 10% Internal Regulated SupplyC4.0 VDC Typical AlignmentD0Chassis GroundE4.0 VDC Typical Doppler (Sensitivity)F0.1 VDC (Normal), Alarm Status10-12 VDC (Alarm)PREVENTATIVE MAINTENANCE_______________________________________________Model 380 requires no calibration other than alignment, RCO and sensitivity adjustment during installation. Tomaintain a trouble free system, the following is recommended.1) Wax the radomes every 3 to 6 months. (At maximum security installations, where detection of prone crawlingtargets is required, wax once a month.)
182) Keep the isolation area clean and free of tall grass, weeds, debris, obstructions and moving objects.3) Upon initial installation, establish a zone data chart. Record input supply voltage, zone distance, transceivermounting height, alignment voltage, RCO setting, sensitivity setting, address codes and battery voltages.4) If standby batteries are used, they should be functionally tested every three months.5) A site inspection should be performed every six months. The inspection should include verifying data from Step3, checking for physical damage (cracks, leaks, corrosion, etc.), checking for isolation zone changes (washouts,materials placement, vegetation growth, loose fence fabric, etc.).6) For troubleshooting information, please contact the factory about Model 380 Service Instructions.OPTIONAL EQUIPMENT_______________________________________________________Model PS40 Power Supply operates from 110 VAC, 50-60 Hz, and 0.5A and furnishes 13.7 VDC at up to 1.6A.
