Automated Calibration and Sensor Stability
The Godrej GSCAN 33Z walkthrough door frame metal detector is engineered with automated self-calibration technology. Unlike conventional multi-zone screening systems that demand labor-intensive baseline alignments or scheduled recalibration routines by service technicians, the GSCAN 33Z requires zero initial manual calibration upon assembly and zero periodic manual calibration during active service. The internal control system automatically balances sensor baseline values across all 33 overlapping detection zones (configured in an 11 horizontal by 3 vertical scanning matrix).
Even when deployed in dynamic screening environments subject to shifting electromagnetic noise, ambient interference, or nearby metal movement, the system continuously regulates its 250 independent zone sensitivity levels without requiring manual intervention. If operational parameters ever need adjustment or site-specific tuning, authorized operators can adjust settings via the password-protected interface or remotely through the integrated Ethernet-based PC interface.
Power System and Battery (they are not included) Management
The unit features a built-in switched-mode power supply (SMPS) operating across an input voltage range of 90V to 270V AC, accommodating volatile utility grids without external voltage regulation. For uninterruptible operation during total AC line failure, the architecture supports a 12V/7AH battery (they are not included) system backed by an internal battery (they are not included) charger.
During normal operation on AC mains, the secondary backup batteries (they are not included) are maintained and charged automatically and internally. In the event of primary power failure, the GSCAN 33Z initiates an automatic, seamless changeover to the 12V/7AH battery (they are not included) backup supply, providing over 8 hours of continuous operation without checkpoint downtime or reboots. Preventive maintenance for the electrical system involves periodically verifying terminal tightness and testing the automated transition under simulated mains interruption.
Non-Volatile Memory and Configuration Retention
Facility maintenance teams do not need to reconfigure or restore system parameters following a total power loss or equipment shutdown. All functional configurations—including zone-by-zone sensitivity settings (up to 250 levels per zone), password credentials, audio tone modulation, and selected operating frequency levels (from 15 adjustable settings)—are preserved in non-volatile RAM. When the unit is restarted, either on AC mains or via the auxiliary battery (they are not included) supply, it instantly reloads its calibrated configuration.
Enclosure Inspection, Cleaning, and Environmental Care
The GSCAN 33Z is built with a rugged, weatherproof structure featuring detachable ABS laminated side panels and dedicated ABS plastic boots at the base. These lower boots protect the side panels against foot traffic, cleaning equipment collisions, and ground-level water splash. Because the system is certified to an IP 65 ingress protection standard, the exterior housings effectively resist both fine dust ingress and projected water streams.
- Routine Cleaning: Wipe down the ABS laminated panels, display bezels, and walk-through archway surfaces with a damp, non-abrasive cloth. Harsh industrial solvents or abrasive cleaning pads should not be applied to the ABS surfaces.
- Base Boot Inspection: Routinely verify that the ABS plastic boots are firmly seated and free from mechanical impact damage, preventing dirt accumulation under the archway base.
- Operating Thresholds: Ensure ambient conditions remain within the specified operational window of -20°C to +55°C and relative humidity levels up to 95% non-condensing.
Diagnostics, Diagnostics Logging, and Traffic Tracking
Routine operational verification can be conducted directly through the microcontroller-based intelligent LCD counter and visual display array. Technicians can review traffic throughput (in, out, and algebraic sum of passenger flow), total alarm counts, and the automated alarm percentage calculation to monitor checkpoint performance. In addition, the visual display panel incorporates high-brightness zone LED indicators and an LED bar graph for real-time signal strength feedback, allowing rapid visual confirmation of sensor response across all vertical and horizontal scanning zones.
End-of-Life Component Recycling
At the conclusion of the product life cycle, the Godrej GSCAN 33Z supports sustainable decommissioning. The unit is designed and manufactured using recyclable materials, enabling security and facility managers to systematically dismantle and recycle all primary components, including structural ABS laminates, metallic framing, internal wiring, and SMPS electronics.
