Description

The MD-327R is a robust alarm device with specific technical parameters that define its functionality and efficiency. Below is an explanation of these parameters to give you a better understanding of the product’s capabilities and suitability for your specific security needs.

Technical Parameters Explained:

  1. Product Model: MD-327R
    • This identifies the specific model of the device, useful for referencing and support.
  2. Alarm Volume: About 100dB
    • The alarm volume is approximately 100 decibels, which is loud enough to be clearly audible in most environments, effectively alerting people to any security breaches.
  3. Supply Voltage: 3V
    • The device operates on a low voltage of 3V, which typically indicates efficiency and low power consumption, making it suitable for long-term use without substantial energy drain.
  4. Static Consumption Current: ≤ 0.8mA
    • The static or idle consumption is less than or equal to 0.8 milliamperes, suggesting that the device consumes minimal power when not actively alarming, contributing to energy efficiency.
  5. Alarm Current: ≤ 500mA
    • During an alarm, the device consumes less than or equal to 500 milliamperes. This is the current used to trigger the loud 100dB alarm and possibly other functions like flashing lights.
  6. Receiving/Transmitting Distance: ≤ 80m (open space)
    • The device can effectively receive or transmit signals up to a distance of 80 meters in open space, making it suitable for medium-sized properties.
  7. Modulation Method: ASK
    • ASK (Amplitude Shift Keying) is a type of modulation used to encode data by varying the amplitude of the transmitted signal. It is commonly used in wireless communication systems.
  8. Receiver/Transmitter Frequency: 433MHz/868MHz (optional)
    • The device operates on two possible frequencies: 433MHz or 868MHz. These are common frequencies used for communication in security devices, ensuring compatibility with various sensors and remotes.
  9. Product Size: L288W201H14mm
    • The dimensions of the device are 288mm in length, 201mm in width, and 14mm in height. This compact size makes it unobtrusive yet functional.
  10. Execution Standards: GB 4943.1-2011
    • This indicates that the device complies with specific safety standards set by GB (likely referring to a Chinese national standard), which covers the safety of information technology equipment, ensuring that the device is safe to use.

Applications: Given these specifications, the MD-327R is suitable for installations in homes, offices, shops, and potentially industrial environments where a powerful alarm sound and effective communication range are necessary. Its low power consumption makes it ideal for settings where minimal maintenance is desired.
