Pre-Installation Site Requirements and Physical Footprint
Proper site selection is critical to ensure optimal screening throughput and prevent operational interference with the continuous wave technology of the Sivananda UPMD 6 Door Frame Metal Detector (SKU: KTI12002003PMD6, HSN: 85437012). The deployment area must accommodate an overall arch assembly footprint of 900 mm (width) x 590 mm (depth) x 2170 mm (height) (± 10 mm). The internal passage clearance provides dimensions of 750 mm (width) x 590 mm (depth) x 2010 mm (height) (± 10 mm).
Installers must verify that the installation surface is level, structurally stable, and capable of supporting the arch assembly's approximate weight of 75 kg. The operating ambient temperature at the installation location must be maintained between -5 °C and +55 °C, with a non-condensing relative humidity range of 0% to 95%. This CE-certified walkthrough system is confirmed safe for cardiac pacemakers and safe for pregnant women, making it suitable for transit stations, airport terminals, university entrances, corporate IT facilities, libraries, and stadium security checkpoints.
Mechanical Unpacking and Floor Anchoring
The standard equipment package supplied from the manufacturer includes the following primary installation hardware:
- 01 DFMD Arch Unit: High-durability structural frame manufactured from Fibre-Reinforced Plastic (FRP) material.
- 01 Mains Cord: Heavy-duty electrical power cable for line connection.
- 04 Foundation Nuts & Bolts: Structural fastening hardware for rigid anchoring to finished flooring.
Position the two vertical FRP side panels and the console header assembly upright at the designated checkpoint boundary. Ensure passage alignment matches transit flow direction before mechanically securing the base plates. Fasten the arch assembly securely into the floor substrate using the four supplied foundation nuts and bolts to prevent structural swaying, vibration, or physical displacement during high-volume pedestrian ingress.
Electrical Connections and Power Verification
The Sivananda UPMD 6 features an internal power supply engineered to operate on standard utility mains from 160 to 270 V AC at 50 Hz, with a power consumption rating of 100 VA. Connect the supplied mains cord to a dedicated grounded single-phase AC outlet. For emergency backup power during line outages, the unit includes an in-built rechargeable battery (they are not included) circuit capable of providing up to 2 hours of standalone runtime.
Upon powering the system, observe the front console status panel, which provides immediate diagnostic LED feedback:
- Mains On: Confirms AC utility power is active and reaching the continuous wave control board.
- Battery Charging: Indicates active DC charge flow to the internal backup battery (they are not included).
- Battery Low: Warns that operational reserve in the backup battery (they are not included) is depleted.
- Overload: Alerts technicians to line power fluctuations or electrical subsystem faults.
System Configuration, Keypad Programming, and Auto-Calibration
Once line power is established, the microprocessor-based architecture executes an automated self-test program and auto-calibration routine. If an operational anomaly or sensor fault is detected across internal coils, a dedicated system FAULT indicator alerts the operator on the console.
All programmatic adjustments are conducted using the integrated console keypad. Operators can configure operational thresholds, alert volumes, and sensitivity levels directly through the menu displayed on the 20 x 2 character LCD screen. The multi-zone detection architecture provides individually adjustable sensitivity across 6 distinct vertical zones, programmable in digital steps from 0 to 99. Tune sensitivity settings based on local security protocols; at standard thresholds, the unit resolves targets as small as a 25 mm ferrous or non-ferrous metal cube.
Optical Sensor Alignment and Traffic Flow Setup
During final commissioning, verify the integrated infrared occupancy sensors located along the passage portal. These sensors govern the multi-mode directional counter, which tracks screening volume across selectable operational metrics: IN traffic, OUT traffic, and Total IN & OUT traffic.
Check line-of-sight operation for visual traffic indicators: the entry side features an illuminated Go / Stop indicator for pedestrian pacing, while the exit side incorporates a dynamic red LED zone display that visually maps detected metallic items to specific vertical sectors. Confirm that the real-time LCD bar graph displays percentage metal indication accurately when passing calibration test pieces through the portal. For integrated multi-portal checkpoints, connect the microprocessor-based PC-compatible interface to central monitoring equipment as required.
