Multi-zone technology discriminates between miniature handguns and harmless objects like keys and coins (Door Frame metal Detector model economy)
Multi-zone DFMDâs deploy âContinuous Wave Multiple Sensor Measurement Techniqueâ over the commonly used âPulse Induction methodâ. This increases screening efficiency and cuts operating costs. Multiple zones of detection allow the exact location of concealed weapons to be pinpointed. A display shows if a weapon is located on the left, right or centre of the person being screened and if it is at ankle, knee, waist, chest or head height. If more than one weapon is being carried each is detected and its location shown. During an ensuing manual search, security personnel can immediately target the object, or objects, that created the alarm(s.).
An important feature of horizontal multiple zone technology is its ability to efficiently discriminate between miniature handguns and harmless objects. People being screened can pass through the detector without the inconvenience of having to empty their pockets of normal amounts of keys and coins. Weapons manufactured from steel, various grades of stainless steel, aluminium, zinc alloys and mixed alloys are detected using a single operating mode.
The technology offers excellent electrical interference rejection, thus eradicating false alarms that halt traffic flows. The equipment is also continuously active, which means that weapons or contraband cannot be passed, slid or tossed through the detector undetected.
