Description

The MD2020 vibration detector is a highly versatile and sophisticated device designed to detect vibrations and monitor the safety of various sensitive environments. This device incorporates advanced technology, including a 3-axis gyroscope accelerometer and a temperature sensor, making it suitable for deployment in crucial areas such as warehouses, ATM locations, and around vulnerable points like glass doors and windows. Here’s a detailed look at its features, functionalities, and specifications.

Functional Features

  1. 3-Axis Gyroscope Accelerometer: This technology enables the MD2020 to quickly detect both vibrations and tilt. The sensitivity to motion makes it ideal for early detection of any intrusion or accidental impact.
  2. Dual Working Modes:
    • User Mode: Simplifies operation with DIP switch adjustments offering up to 4 levels of sensitivity, making it accessible for general users without technical expertise.
    • Engineering Mode: Provides finer control with up to 16 levels of sensitivity adjustments, catering to environments that require precise calibration.
  3. Adjustable Alarm Sensitivity and Vibration Strikes: Users can set the threshold for what constitutes an alarm event, which is critical for reducing false alarms and ensuring that only significant incidents are flagged.
  4. Tool Attack Monitoring: The device can detect vibrations specific to various tools like drilling machines, hot spears, electric tools, and manual tools such as hammers or chisels, enhancing its utility in security applications.
  5. Sensitivity Adjustment Method: Sensitivity can be adjusted remotely via RS-485 commands or manually on-site, providing flexibility in maintenance and configuration.
  6. Temperature Sensor: Incorporating a temperature sensor that triggers an alarm if the temperature of the device environment changes by more than 5 degrees Celsius within 30 seconds, adds an additional layer of environmental monitoring.
  7. Automatic Axis Balance Correction: This function ensures that the device maintains accuracy and reliability in its readings, irrespective of minor positional changes or after installation.
  8. Compact and Durable Design: With an ABS shell and a mini design, the MD2020 requires minimal installation space and offers durability, making it suitable for a wide range of applications.
