Product information

Description

The Eura MA-05A3 door and window contact sensor is a compact security device featuring an integrated siren. It is designed to monitor the opening of doors or windows, providing an immediate audible alert when the magnetic contact is broken. The device operates independently without the need for complex wiring, making it a practical solution for enhancing security in various indoor environments.

Advantages

This sensor offers a dual-functionality mode, allowing users to choose between a short entry chime or a continuous alarm signal. Its wireless design ensures a straightforward installation process, as the unit is mounted using double-sided adhesive tape, eliminating the need for drilling or cables. The device is energy-efficient, ensuring long-lasting performance on a standard battery set, and includes a manual switch to easily disable the alarm when not required.

Suitable for

  • Residential homes and apartments
  • Office spaces
  • Garages and storage sheds
  • Camping trailers and mobile homes

This device is not suitable for outdoor use as it is rated with an IP20 protection level, meaning it is not resistant to moisture, rain, or extreme weather conditions. It is also not intended for high-security applications that require remote monitoring or integration with professional alarm systems.

Key specifications

  • Power supply: 4.5V DC (3 x LR44 1.5V batteries)
  • Alarm volume: 105 dB at 1 meter
  • Current consumption during alarm: 100 mA
  • Operating temperature range: +10ºC to +40ºC
  • Dimensions: 65 x 30 x 25 mm and 37 x 13 x 17 mm
  • Protection rating: IP20
  • Weight: 40 g

How to use

To install the sensor, clean the surface of the door or window frame and the moving part of the door or window. Apply the provided double-sided adhesive tape to the back of both sensor components. Position the two parts so that they are aligned and in close proximity when the door or window is closed. Once mounted, select the desired operating mode using the integrated switch. When the door or window is opened, the magnetic contact is broken, triggering the selected acoustic signal.

What to consider before purchase

  • Ensure the mounting surface is clean and dry for proper tape adhesion
  • Verify that the operating temperature of the location stays within the +10ºC to +40ºC range
  • Check that the batteries are installed correctly before mounting
Usage recommendations: Regularly test the alarm functionality by opening the protected door or window to ensure the batteries are providing sufficient power for the 105 dB siren.
