Defines a low frequency threshold Sensor signal below the Lowest low frequency threshold is not used by the algorithms when frequency detecting events alarms Sensitivity Adjusting the sensitivity of either the cut or the climb processor raises or lowers the overall sensitivity of that processor Although raising the sensitivity level increases the likelihood of detecting an intruder it also makes it more likely that something such as wind or animals might generate a nuisance alarm When setting the sensitivity it is necessary to strike a balance so that the processor is sensitive enough to detect the sort of intrusions you are looking for but not so sensitive that it triggers alarms from local nuisances For these reasons the sensitivity setting can only be determined through adjustment and subsequent system testing Generally the processor sensitivity should be adjusted for the minimum value that adequately detects a simulated intruder ensuring the system is no more sensitive than necessary Event count One of the best ways to differentiate valid threats from nuisances is by the number of times a signal is generated in a given period of time Generally a nuisance such as an animal or tree branch doesn t make consistent disturbances as an intruder does The event count specifies the number of times an event must occur within a specific amount of time before the APU generates an alarm For the event counter to increment on

32. rding the sensor cable 1 The sensor cable detects movement so you want to install it in such a way that it vibrates when an intruder is present but not when non threatening things such as wind or animals are present Page 16 2 The sensor cable has the same level of sensitivity throughout its entire length Areas that are easily vibrated by intruders need less coverage by the sensor conduit than areas that are not as easily vibrated 3 The APU does not distinguish the intruder s location along the sensor cable To localize the intruder separate the perimeter into zones that are small enough to be quickly checked when an intruder trips the alarm Make the fence quiet Wind is one of the biggest sources of nuisance alarms The best way to avoid these notifications is to make the fence quiet when the wind blows Here are some specific things you can do to accomplish this e Install high quality fence o For chain link fences re tension the fence fabric if it is loose and add more ties to the fence fabric and the fence signs as necessary to prevent them from slapping or banging the fence and posts when the wind blows e Deploy uniform zones o Within a zone the type quality and tension of the fence should be uniform e Keep the fence line clean o Keep the area on both sides of the fence clear of tree limbs and other vegetation that might brush against the fence when the wind blows Clear the outside perimeter of objects that mig
