The Godrej GSCAN 33Z walkthrough door frame metal detector (DFMD) provides high-throughput threat screening across demanding access-control environments. Engineered with 33 overlapping detection zones, an IP 65 weatherproof chassis, and high immunity to electromagnetic interference, the system addresses physical security requirements across diverse industrial, civil, and commercial facilities.
Mass Transit Checkpoints & Multi-Lane Screening
In high-density transit facilities such as airports, metro stations, and railway terminals, security infrastructure must sustain rapid passenger ingress without generating screening bottlenecks or electromagnetic interference. The GSCAN 33Z supports an operational transit rate of up to 20 persons per minute through an internal passage measuring 2040 mm high by 750 mm wide.
- Multi-Unit Array Deployment: Integrated 15-level adjustable operating frequencies allow multiple walkthrough units to run directly adjacent to one another without radio frequency cross-talk.
- Immunity to Terminal Electronics: Engineered shielding provides high immunity against electrical interference emitted by neighboring X-ray inspection machines, computer monitors, CCTV screens, chokes, and heavy electrical distribution transformers.
- Traffic Auditing: The built-in microcontroller-based intelligent LCD screen continuously registers directional footfall, reporting inbound counts, outbound counts, algebraic net traffic sums, total alarms, and overall alarm percentage.
Critical Infrastructure, Energy, & Industrial Plants
Facilities such as oil, gas, and power plants, substations, and heavy industrial sites require screening checkpoints capable of operating continuously in exposed or harsh environmental conditions. Certified with an IP 65 ingress protection rating, the unit prevents dust ingress and resists water spray, operating reliably in temperatures ranging from -20°C to +55°C and relative humidity up to 95% non-condensing.
For remote perimeter gates prone to unstable power delivery, the unit runs on SMPS 90–270V AC mains and incorporates an automatic, seamless transfer to a 12V/7AH battery (they are not included) system. The integrated charger maintains the battery (they are not included) during normal operation to supply over 8 hours of continuous uptime during power failures. System parameters remain secured in non-volatile RAM, preventing configuration data loss after total power-downs.
Government, Defence, & Police Facilities
High-security access points in government buildings, police headquarters, and defence sector installations demand precise localization of concealed metallic threats. The GSCAN 33Z adheres to the NIJ 0601.02 standard for detecting ferrous and non-ferrous metals, reliably locating targets as small as a 9mm bullet across X-axis, Y-axis, and Z-axis orientations.
- Precise Threat Triangulation: 33 distinct detection zones arranged in an 11 horizontal by 3 vertical matrix isolate target positions using high-brightness LED zone displays, LED bar graph signal strength indicators, and independent audio/visual alarms.
- Discrimination Control: 250 individual sensitivity levels per zone minimize cumulative signal effects caused by benign distributed metallic items, avoiding unnecessary pat-downs.
- Tamper Prevention: Password protection restricts configuration access to authorized operators, preventing field modification of sensitivity parameters.
Enterprise, Healthcare, & Public Gathering Venues
Commercial office towers, shopping malls, stadiums, places of worship, schools, and hospitals require sensitive screening that safeguards visitor health and operational continuity. Emitting low magnetic field strength, the GSCAN 33Z is safe for visitors with cardiac pacemakers and will not damage magnetic recording media. In medical and clinical environments, the 33-zone detection architecture aids in locating foreign bodies, intraocular metallic fragments, medical devices, and swallowed coins.
Temporary Checkpoints & Event Security
For public events, trade exhibitions, and outdoor gatherings, the detector's 70 kg modular frame simplifies logistical deployment. Detachable ABS laminated side panels and ABS bottom boots enable quick field assembly, transport, and tear-down, while automated self-calibration eliminates the need for initial or periodic manual calibration on site.
