Remote alarm monitoring made simple

May 2020 IS & Ex

Alarms are normally managed on site by personnel charged with supervising the plant/facility and ensuring the continuity of the operation. Alarms are implemented to help manage operations and mobilise resources in order to return the operation to normal operational conditions after a fault has occurred.


Combining the power of remote terminal units (RTUs) and cloud-based server technology allows Omniflex to manage alarm annunciators remotely via Web-based technology. An RTU is used to communicate with the alarm annunciators using Modbus serial communications (up to 15 units – 240 alarms). The alarm status is transmitted via GSM to the Data2Desktop cloud-based servers, providing user access from any Internet browser and effectively allowing the alarm systems on site to be monitored and managed remotely. The system has the following key features:

• Supports up to 15 annunciators on a single serial port.

• Allows users to enter a manned mode or unmanned status mode.

• Programmable Teleterm units in PLC language IEC61131 for local automation functions.

• Auxiliary inputs or outputs for control.

• Compact self-contained Teleterm gateway.

• Battery backup for power interruptions.

• Independent of on-site Internet connections.

System benefits

• Easy installation.

• Configurable and easy customisation.

• Wireless connection with global access.

• Low-power operation (battery backed).

• Alarm logging.

• Automated reporting for management.

• Maintenance: staff mobilisation via alerts.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
