Where to use Microwave Sensors Open outdoor storage areas Sallyports in Correctional applications High security areas with dual fences Trucking companies Gas and Oil storage sites Nuclear power generating sites Nuclear fuel storage sites Power utility substations Roof top applications for traps
Microwave 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 flat Don’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 beam Do use in areas where ground is smooth Don’t use over drainage ditches, ungraded areas where there is more than 6 inches change in terrain over the length of the zone
Microwave Protection System: Do and Don’t List Do use in area which is free of extraneous motion Don’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 fenced Don’t use in unfenced areas because of problems with animal-caused nuisance alarms
Microwave Protection System: Do and Don’t List Do mount Microwave link zone at least 15 feet in from the fence line Don’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 alarms Do keep links out of traffic areas and provide protective devices to prevent damage Don’t mount links near fence gates that can swing into the heads
Microwave Protection System: Ground Cover Crushed rock is best ground surface to deploy microwave links over Crushed rock allows proper drainage of rainwater and prevents puddling If 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 alarms Well-mown grass (3 inches or less), asphalt, concrete, hard packed soil, are good for medium and low security sites.
Microwave Zones: Type of Security High Security Zone –Detection of intruder stomach-crawling parallel to and through the beam Medium Security Zone –Detection of intruder crawling on hands and knees through the beam. Low Security Zone –Beam-break alarm only –Detection of a walking intruder, vehicles, etc.
Microwave 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 vegetation Transmitter/Receiver units mounted 24 inches beam centerline (center of antenna) to ground
Microwave Protection System: Site Design Start by making detailed sight drawing Show all dimensions, including terrain variations, drainage ditches, types of pavement, etc. Zone placement must provide clear line-of-sight between transmitter and receiver Zone length will depend on degree of security required. –High security zones may not be over 100 m –Medium Security zones may not be over 150 m –Low security zones may be up to 183 m –Trees, buildings in area may require shorter zones
Microwave Protection System: Site Design Offsets –Microwave energy starts as a very narrow beam (6 inches wide) –Area immediately below and in front of transmitter and receiver are not protected –To compensate for this each zone must be installed to provide protection to its adjacent zone –Following charts depict proper offset placement based on a mounting height of 76 cm (30 in.) above ground (High Security Site)
