Model 320SL Dual Synchronized (Stacked)
Microwave Link

“I lnew I was dealing with a quality product when I walked onto a new site for my company and found a 16-year-old Southwest Microwave stacked link still in opertion.”

Tom Wein, Security Systems integrated

Model 320SL is a dual (stacked) perimeter microwave intrusion detection system designed for protection of high risk assets. The lower link, typically mounted between 300 and 460 mm (12 to 18 in) above grade, is a Perimeter System Model 310B. This link operates at K-band frequency (24.125 GHz) to provide a very narrow detection pattern that has been optimized to detect a slow prone crawling intruder (30 cm standard metal sphere radar target). The upper link, mounted between 0.7 and 1 m (30 to 40 in) above grade, is a Perimeter System Model 300B. Operating at X-band frequency (10.525 GHz), this link provides a medium-width detection pattern designed to detect a walking, running, or jumping intruder.

To detect bridging attempts, additional links may be stacked to increase overall detection zone height. When it is advantageous to utilize additional 300B or 310B links or transceivers, a single twisted pair of wires may be connected between the transmitters of the links allowing them to be slaved together or connected to Model SMC10 Syncplexer for full synchronization. Any transmitter may be selected as the master with the other slaved to it, or both links synchronized from the crystal controlled SMC10 Syncplexer. Full synchronization prevents mutual interference between two or more X-band or K-band links or transceivers.

Model 320SL provides near-perfect detection even on crawling or rolling intruders with a radar cross section as low as 0.2 square meters. Because the X- and K-band links are designed to detect specific targets, detection can be accomplished with very low sensitivity settings. For this reason, Model 320SL provides outstanding NAR/FAR performance – even in severe environments
