GSM Guard GT1000PRO

GSM Guard GT1000PRO is an advanced NB-IoT alarm device developed for professional installations where stable operation, flexible monitoring and mobile alerting are crucial.

The unit has 2 configurable inputs, One temperature input for DS18B20 summit 1 relay output, which makes it suitable for alarm handling, monitoring, and remote control.

is especially used in The VA industry, where it is often used in conjunction with float switches for monitoring wells, tanks, and technical installations.

In the event of an alarm, the device can send a message via Calls, SMS, or email – at the same time as the built-in buzzer can provide a clear local acoustic alarm.

LegacyLINK – Tried and tested and stable communication protocol

LegacyLINK is our thoroughly tested communication protocol, which has been a central part of the GSMCloud platform since 2020. The protocol has been developed with a focus on Stabilne dryfowanie, simple communication and long lifespan in professional installations.

With LegacyLINK, the device sends a data packet to GSMCloud and subsequently receives a reply back. This form of communication provides a Robust and predictable data exchange, where the unit works stably in the field, while Intelligence, configuration, and management are handled centrally in the cloud.

The communication interval can typically be adapted from every 10 seconds up to 1440 minutes, depending on the needs of the individual solution. This makes LegacyLINK suitable for both monitoring, status reporting, and control tasks, where Driftssikkerhed, flexibility and High complexity are important requirements.

LegacyLINK is an important part of the foundation behind GSMCloud and is still used in many products and installations, where tried and tested technology, stable communication and Long-term operation are central elements. The protocol is particularly well-suited for solutions where a simple and well-tested communication model creates high stability and easy integration.

NB-IoT – Stable IoT communication for professional controls

NB-IoT is an efficient communication technology for professional IoT controls, where Low power consumption, Stable connection and reliable data transfer is crucial.

The technology is based on a Narrowband LTE standard, developed for IoT devices that need to send small amounts of data securely and efficiently over the mobile network. This makes NB-IoT particularly suitable for solutions where the device needs to operate stably in the field for a long time.

With NB-IoT, our IoT controllers get a Robust mobile connection, which is suitable for monitoring, measurement data, alarm management and control tasks – also on installations without a traditional internet connection.

Built-in buzzer with 80 dB acoustic alarm

The unit has a built-in buzzer which provides a clear acoustic alarm of up to 80 dB directly from the unit. This makes it easy to detect water leaks or other critical events locally – even before the message is received via SMS, call or email.

The buzzer can be freely programmed via our flow, so you decide when and how the alarm should be activated. For example, it can be used for water detection, technical errors, delayed alarms, or as a local warning in combination with remote alarming.
