Answer:
The UPMD 004 utilizes continuous wave multi-zone electromagnetic technology divided into 4 independent detection zones, each offering 0 to 99 digitally adjustable sensitivity steps. It reliably detects ferrous, non-ferrous, and conductive alloy objects down to a 25 mm cube and maintains active coverage even if metal is tossed through the frame.
The Sivananda UPMD 004 employs continuous wave electromagnetic scanning driven by a dedicated microprocessor architecture to monitor four distinct vertical zones. Key operational detection parameters include:
- Zone Configuration: 4 discrete horizontal/vertical inspection zones, allowing security operators to identify whether concealed targets are located at head, torso, waist, or lower limb levels.
- Independent Zone Calibration: Each zone features independent threshold and sensitivity calibration across 0 to 99 variable digital increments via the integrated keypad. This allows fine-tuning to counteract ambient floor rebar interference without compromising upper-body detection.
- Target Resolution: Calibrated to detect ferrous, non-ferrous, and alloy targets as small as a 25 mm metal cube.
- Continuous Active Field: The detection field remains continuously energized; metallic threats thrown or tossed rapidly through the archway cannot bypass the coil response.
- Integrated Auditing: Built-in infrared occupancy sensors drive a multi-mode traffic counter that logs transit metrics including IN, OUT, Total IN & OUT counts, and relative alarm percentages on the backlit console display.
