Replacement for G-2025 GSM Gate Opener

Use G4000 to replace G-2025 GSM Gate opener

The three major network providers in Australia shut down their 3G networks in January 2024 (Vodafone) and November 2024 (Telstra and Optus), switching to a different technology for voice calls called VoLTE (Voice over Long-Term Evolution). This impacted devices in Australia, including mobile phones, smartwatches, tablets, phone diallers etc. This switchover also affected the G-2025, which stopped supporting voice calls.

The G4000 was designed as a compatible replacement using high-quality Telstra-approved Canadian 4G modules. The G4000 GSM dialler is designed for the remote control of gates, doors, garages and other electrical devices. Users can manage entry points by simply calling the device’s phone number from their mobile phones, removing the need for traditional keys or access cards. It is equipped with Bluetooth capabilities, allowing users to update device settings wirelessly through the Elsema Mobile App. This allows users to make changes to the G4000 on-site without the need to bring it near a computer.

The G4000 also offers the convenience of setup via SMS commands, allowing users to configure the device remotely. This feature enables easy management and quick updates without requiring physical access to the unit. Additionally, the Elsema Desktop App provides a user-friendly interface for importing bulk numbers directly from an Excel file, reading numbers from the G4000 and exporting them back to an Excel file.

The G4000 provides all the functions of the G-2025 while introducing advanced features and enhanced security. The G4000 offers the following features:

  • Operates with a free phone call
  • Operates on Telstra, Optus & Vodafone networks
  • Up to 2000 users
  • Secure password protected
  • Mobile App for easy setup
  • Remote setup option via SMS
  • Desktop App for backup of numbers to an Excel file
  • Desktop App for restoring numbers from an Excel file
  • Digital Input activation to send SMS alerts
  • Digital Input activation to make voice calls
  • View history via Mobile App or Desktop App
  • Multi-colour LED for status indication

For applications that require advanced features or multiple inputs and outputs, the G5000 is a better choice. This advanced model supports both digital and analog inputs and provides four relay outputs that can be controlled via SMS or phone calls. The G5000+ further enhances connectivity by enabling machine-to-machine communication, allowing one G5000+ to communicate with another.

What is the best replacement for the G-2025 GSM gate opener?
The G4000 4G GSM gate opener is the direct replacement for G-2025, providing the same free call access plus modern 4G VoLTE connectivity and added features.
After the Australian 3G shutdown and move to VoLTE by Telstra, Optus and Vodafone, legacy GSM voice-based devices like G-2025 could no longer place or receive calls as before.
Authorised users call the G4000 number, the unit checks caller ID then rejects the call and briefly switches its relay so access is free with no call charges.
The G4000 works with Telstra, Optus and Vodafone 4G VoLTE networks using a suitable SIM so it can operate anywhere 4G coverage is available.
The G4000 can store up to 2000 authorised phone numbers which suits large residential sites, strata complexes and commercial facilities.
Initial setup is done with the Elsema mobile app over Bluetooth, then users can be added or edited via SMS or with the desktop app using Excel lists.
Yes, its digital input can trigger SMS alerts and voice calls when an external sensor or alarm changes state.
Choose G5000 when the job needs four relay outputs plus two digital and two analog inputs with SMS control and monitoring rather than a single gate relay.
G5000 Plus supports machine-to-machine communication so one unit can talk to another and offers more advanced automation and alert options.
In most cases no, because both G4000 and G5000 use voltage-free relay outputs that integrate with existing gate and door controllers.
