The Sivananda UPMD 004 multi-zone door frame metal detector (DFMD) provides continuous, microprocessor-driven perimeter access control across facilities that handle demanding pedestrian volumes. Built with a continuous wave electromagnetic detection field and four independent detection zones, the unit identifies concealed ferrous metals, non-ferrous metals, and conductive alloys while maintaining continuous transit auditing.
Mass Transit Hubs: Airports, Railway Stations, and Public Transport Terminals
High-density transit choke points require fast, reliable patron screening that prevents physical bottlenecks while ensuring absolute weapon interception. In railway stations, bus interchanges, and airport terminal access points, the UPMD 004 delivers real-time transit auditing through integrated infrared occupancy sensors. These sensors drive a multi-mode counter that tracks IN, OUT, and Total IN & OUT pedestrian passage alongside a percentage alarm rate indicator. The walk-through archway remains continuously active, ensuring that threats tossed through the 750 mm wide by 2000 mm high internal passage clearance cannot evade detection.
Corporate IT Offices, Tech Parks, and Commercial Buildings
Corporate headquarters, IT campuses, and commercial multi-tenant buildings require non-invasive screening that safeguards personnel and prevents unauthorized hardware or concealed items from entering secured floors. With digitally controlled sensitivity adjustable across 0 to 99 variable steps per zone, security staff can calibrate the threshold of each individual zone to identify small targets down to a 25 mm ferrous or non-ferrous cube. Furthermore, the unit is certified safe for individuals with cardiac pacemakers and will not damage magnetic recording media, ensuring safe everyday transit for employees and visitors.
Universities, Libraries, and Public Institutional Facilities
Institutional libraries, municipal halls, and university campus entrances balance welcoming architectural environments with strict access screening. The UPMD 004 utilizes durable Fibre-Reinforced Plastic (FRP) side panels and archway housing with a compact 910 mm by 590 mm floor footprint. The unit’s automated self-calibration routine (AUTO Calibration) initializes upon power-up on standard 230 V AC (±10%) mains supplies, minimizing setup complexity for facility managers while an internal self-test program and system FAULT indicator provide continuous operational diagnostics.
Stadiums, Sports Arenas, and Event Venues
Large-scale public venues face concentrated arrival surges where screening infrastructure must withstand physical transit forces and wide ambient conditions. The 75 kg archway assembly comes equipped with four heavy-duty foundation nuts and bolts to anchor the frame firmly to the floor, preventing mechanical shift or tipping in crowded concourses. Engineered with an operating temperature tolerance ranging from -10°C to 50°C, the UPMD 004 maintains uninterrupted signal evaluation during outdoor-sheltered or unconditioned entrance staging.
Industrial Plants and Secure Manufacturing Sites
Manufacturing floors, industrial parks, and supply chain warehouses deploy the UPMD 004 at gatehouses and shift-change security portals to counter pilferage and control weapon access. Facility teams can leverage the unit’s PC connectivity interface to stream logging data into centralized control systems, monitoring alarm percentages across shift rotations while tracking transit counts via the integrated on-board display.
