Counters repetitive movements, small animals and ‘over-ranging' issues
Continuing its drive to reduce and possibly eradicate false alarms even in the most demanding environments, Optex Europe - leaders in detection technology - has launched REDWAVE, a new external detector that combines several technologies in a single unit to provide the optimum installation performance.
The product has been designed specifically to counter the three major headaches for installers-remote monitoring centres, end-users associated with false alarms in outdoor detection such as repetitive movement from objects such as trees, flags, advertising bunting etc, small animals - from foxes and other mammals to insects flying in front of the detector and ‘over-ranging' - alarms triggered by activity (e.g. from passing vehicles) beyond the perimeter being protected.
In addition to using passive infrared (PIR) and microwave technology as in conventional combination detectors, REDWAVE also has Adjustable Microwave Range Limiter (AMRL) technology that allows users to adjust the detection distance, and a Dual Quad Zone Logic (DQZL) PIR that uses two PIR detectors to increase detection density and eliminate undetectable areas.
With conventional outdoor combination detectors, microwave transmission distances are not easily adjusted, resulting in many false alarms being triggered from outside the detection area. AMRL technology incorporated within REDWAVE, however, enables installers to choose the real detection distance required with a dial setting that offers seven, five metre intervals between zero and 30 metres.
REDWAVE also uses two, vertically configured PIR detectors that create two different, highly dense detection areas, one near and one far. The dual coverage essentially eliminates dead detection spots, preventing the likelihood of ‘missed' alarms. Furthermore, the sensitivity of each area can be adjusted separately.
Each PIR uses Quad Zone Logic providing multi-segmented detection zones throughout the detection area and an alarm signal base on the cumulative energy of each zone. This greatly reduces false alarms, particularly those caused by sudden small temperature changes from light reflections or small animals.
The result is a detector with false alarm reduction properties second to none. As Optex Europe's Divisional Sales Manager Nigel Hackett concludes: "REDWAVE is a ‘win win' product for everyone involved in providing external protection."
"Customers have a system that is more reliable than any other product currently available; installers have a detector that satisfies their customers' needs and the Remote Video Response Centres (RVRCs) have a detector that helps improve their operational efficiency, reduces costs, and that their operators can trust in the event of an alarm activation as being genuine."
