Reduced false alarms with new Optex ceiling-mounted detector

(12/09/2007)

Optex Europe has launched the KX-08 ceiling-mounted detector for small commercial and residential applications that incorporates several layers of technology for greater stability, leading to reduced false alarms.

Based on the RX40 PIR series, the new detector incorporates not only Optex’s Quad-Zone-Logic technology but also an in-built Pet Tolerance (PT) feature to provide superior performance even in high white light scenarios. The detector also features improved protection against masking caused by stock or displays being located too close to traditional wall-mounted detectors.

Launched exclusively through ADI, the KX-08 provides wide-angle (85°) coverage with a 78-zone detection pattern. Quad-Zone-Logic provides 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 animals.

Easy to install, the new detector is aesthetically designed to blend unobtrusively in any room. It is also small, measuring 2.09 inches (53mm) in height and with a width of 5.39 inches (137mm). The sealed unit provides excellent immunity against insect ingress and features temperature compensation (via the ECO chip), two/four pulse count adjustment, LED disable and a spherical lens. The lens obtains an accurate focal length for each detection zone and maximises the performance of the QZL.

“Unlike traditional wall-mounted detectors, the KX-08 eliminates the need for vulnerable or unsightly wall/ceiling brackets as a result of its sleek, low profile ceiling-mount design,” explains Paul Nicholas, Sales Manager at Optex Europe. “The power behind the KX-08 is our patented Quad-Zone-Logic Technology and an ECO chip which means it can tell a human target from a moving curtain for example.”

“A human body would cause four to eight zones to fill, which causes an alarm signal,” Paul continues. “But the temperature change from a moving curtain (or animals of up to 16 inches in height) would only activate one or two zones at the same time, creating a much weaker detection signal. These signals are then further analysed by the ECO chip and signal processing circuit for greater accuracy.”
