Description
DFMD-SZ is a reliable single piece walk-through metal detector system that does not require a separate control unit. It has been developed to detect clandestine ferrous and nonferrous metals on the body of a person when asked to pass through the door frame. Special ferrite detection circuitry has been employed to detect weapons concealed in ferrite containers.
It has been designed for fast installation and operation under all environments. Long life LED Walk/Stop indicators are incorporated on top of the door frame to regulate the flow of traffic. All controls and audio/visual alarms such as Piezo transducer, LED bar graph, indicator lamps and sensitivity controls are provided at the rear top of the door. Small, medium and large metal objects are indicated by three separate large sized LED indicators that have a wide viewing angle.
