Answer:
The UPMD 6 frame is constructed from Fibre-Reinforced Plastic (FRP) and utilizes continuous wave technology across six detection zones with independent sensitivity settings. Traffic and alarm reporting includes an entry-side Go/Stop optical indicator, an exit-side red LED zone display, and a console-mounted 20 x 2 LCD with a percentage metal indication bar graph.
The Sivananda UPMD 6 utilizes specific construction and visual signaling hardware tailored for high-volume checkpoint screening:
- FRP Construction: The archway structure is fabricated from durable Fibre-Reinforced Plastic (FRP) composite material.
- Six-Zone Continuous Wave Detection: The multi-zone architecture divides the walkthrough aperture into six detection zones, each offering independent sensitivity threshold programming from 0 to 99 via an onboard membrane keypad.
- Visual Flow and Zone Signaling: Features an entry-side optical Go / Stop indicator for pedestrian flow regulation and exit-side red LED zone indicators to pinpoint the exact vertical location of detected items on the body.
- LCD Console Interface: A 20 x 2 character alphanumeric LCD provides system setup data, directional count diagnostics (IN, OUT, and Total IN & OUT tracked via infrared occupancy sensors), and an LCD bar graph indicating metal mass percentage.
- Status Indicators: Dedicated console LEDs display Mains On, Overload, Battery Charging, and Battery Low (they are not included) conditions.
