DET-REXT-PIR30 Perimeter Radio PIRInstallation InstructionsIntroductionThe DET-REXT-PIR30 is an outside radioPIR (Passive Infra-Red) detector forperimeter protection. The unit uses twoindependent detectors, both of whichmust trigger to cause the detector tosignal an alarm. The detector deliversprecise, reliable presence detection.The unit is battery-powered, has arange of up to 30 metres and can bealigned without any change to externalappearance.Package contents:1 x DET-REXT-PIR30 detector1 x drilling template for fixing holes3 x wall plugs and fixing screws2 x additional sliding curtains2 x additional tamper feet1 x tamper foot cup1 x self-adhesive lens mask1 x opening tool2 x CR123 lithium batteriesBattery safety:• Do not put in a fire• Do not heat• Do not charge• Do not short circuit• Do not disassemble• Only fit batteries of the same typeand voltage• Fit lithium batteries only• Observe correct polarityNote: It is recommended you followthese instructions and configure thedevice before mounting it.This product must be installed byqualified service personnel.Installing the unitStep 1: Choose locationThe PIR detects changes in heat andmovement; therefore items such astrees, shrubs, ponds, boiler flues,air conditioning units and animalsshould be considered. The sensor ismore sensitive to movement acrossthe beams than to movement directlytowards or away from the beams.The ideal mounting height is 3m. Atgreater heights, the target may needto move a greater distance before analarm is generated.For pet tolerance, a mounting heightof 1.5m is recommended, the creepmirror must be removed from aroundthe PIR sensor and the lower half ofthe lens must be masked (Figure 2).CoverageThe following provide examples ofcoverage, depending on mountingheight, tilt and lens masking. A markeron the side of the detector assemblygives the degrees of tilt. The examplesassume default programming settings.0° tilt, no lens maskingFigure 1. Optimum coverageNote: The range in Figure 1 reduces to20m by masking the upper section ofthe lens. Masking the upper sectionand programming for minimum rangereduces the range to 6m.Note: If the detector is mounted at 6m,
