1Microwave Protection System Intelli-WAVEMicrowave Protection System
2Intelli-WAVE: Microwave Protection System Volumetric, line-of-sight perimeter intrusion detection system - X-band radarDielectric Resonant Oscillator for greater frequency stability over temperature rangeAdjacent channel rejection - six field selectable channels with greater than 60 dB. rejection betweenPreamplifier for higher fade margins & greater applicationsField adjustable - phase lock loop (PLL) signal processing with user adjusted sensitivity for optimum detection
3Intelli-WAVE Microwave Protection System Range from 3 to 183 mTamperproof - completely enclosed in rugged all-metal housing with integral rain shieldAudible side-tone - output proportional to radar target velocity & cross section for alarm assessment and troubleshootingEasy installation - transmitter and receiver install on postsLow current operation - less than 75 mA/12 VDCBuilt-in lightning suppression on all inputs and outputs
4Intelli-WAVE: Microwave Protection System Polarization diversity: rotatable antenna arraysRemote self test inputSelf-supervising transmitter option (power only)Built-in LED bar graph for alignmentOptional multiplex communicationsRear access to electronics without disturbing the alignmentFCC certifiedTrouble free reliable operation - 15 year MTBFReceiver Modular Components
5Where to use Microwave Sensors Open outdoor storage areasSallyports in Correctional applicationsHigh security areas with dual fencesTrucking companiesGas and Oil storage sitesNuclear power generating sitesNuclear fuel storage sitesPower utility substationsRoof top applications for traps
6Microwave Protection System: Do and Don’t List Do use in clear areas where you have clean line of sight - Detection zone should be long and flatDon’t use in areas where line of sight will be blocked, such as; parking areas, near fixed objects in beam (out buildings, guard shacks), power or light poles in direct center of beamDo use in areas where ground is smoothDon’t use over drainage ditches, ungraded areas where there is more than 6 inches change in terrain over the length of the zone
7Microwave Protection System: Do and Don’t List Do use in area which is free of extraneous motionDon’t use in area with trees or shrubs in or near detection zone. Vegetation within detection zone will cause nuisance alarms. Don’t use near large areas of water, such as: ponds, streams, drainage ditches, property run off areas.Do use in area that is fencedDon’t use in unfenced areas because of problems with animal-caused nuisance alarms
8Microwave Protection System: Do and Don’t List Do mount Microwave link zone at least 15 feet in from the fence lineDon’t mount the Microwave link too close to the fence as it will make it easy to jump over the beam and fence movement can cause alarmsDo keep links out of traffic areas and provide protective devices to prevent damageDon’t mount links near fence gates that can swing into the heads
9Microwave Protection System: Ground Cover Crushed rock is best ground surface to deploy microwave links overCrushed rock allows proper drainage of rainwater and prevents puddlingIf in snow area, pavement is most suitable surface. Pavement allows snow to be removed easily. Snow build-up can cause changes in microwave pattern and nuisance alarmsWell-mown grass (3 inches or less), asphalt, concrete, hard packed soil, are good for medium and low security sites.
10Microwave Zones: Type of Security High Security ZoneDetection of intruder stomach-crawling parallel to and through the beamMedium Security ZoneDetection of intruder crawling on hands and knees through the beam.Low Security ZoneBeam-break alarm onlyDetection of a walking intruder, vehicles, etc.
11Microwave Protection System: High Security Zones Transmitter/Receiver separation distance no greater than 328 feet (100 meters)Terrain must be level to grade, ±3 inches (7.6cm)Terrain finished with crushed rock (1 inch max.) to a depth of 4 inches or paved zone completely void of vegetationTransmitter/Receiver units mounted 24 inches beam centerline (center of antenna) to ground
12Microwave Protection System: Site Design Start by making detailed sight drawingShow all dimensions, including terrain variations, drainage ditches, types of pavement, etc.Zone placement must provide clear line-of-sight between transmitter and receiverZone length will depend on degree of security required.High security zones may not be over 100 mMedium Security zones may not be over 150 mLow security zones may be up to 183 mTrees, buildings in area may require shorter zones
13Microwave Protection System: Site Design OffsetsMicrowave energy starts as a very narrow beam (6 inches wide)Area immediately below and in front of transmitter and receiver are not protectedTo compensate for this each zone must be installed to provide protection to its adjacent zoneFollowing charts depict proper offset placement based on a mounting height of 76 cm (30 in.) above ground (High Security Site)
