Panel-mounted smart alarm | fault | status signal panel | 24 inputs | 24VDC | 223x178x142mm | Modbus RTU | GOOSE | DNP3.0 | IP40

Smart alarm and annunciation terminal – a programmable networked device for visual and audible alarm indication and event recording, designed for monitoring operating states and fault signals in electrical substations, power plants, industrial facilities, energy systems and other control systems.

The device features 24 alarm / status inputs, a 9" colour touchscreen LCD, audible alarm indication and SOE (Sequence of Events) recording with time resolution of up to 1ms. This version is designed for 24V DC power supply and 24V DC status signals.

Main application

The terminal is designed to centrally receive, process and display various fault, process and status signals to the operator. Up to 24 individual alarms can be displayed on one screen.

The system can be used either as a standalone 24-channel alarm terminal or as part of a larger networked annunciation system in which several similar terminals are interconnected.

24 alarm and status inputs

The standard configuration includes 24 alarm inputs. In this version, the input signal voltage is 24V DC.

The inputs are optoelectrically isolated, providing electrical isolation between the control electronics and external status signal circuits.

9" colour touchscreen LCD

The device uses a 9" colour LCD with LED backlight and capacitive touch control. Display resolution – 800x480 pixels.

In the standard 24-alarm configuration, approximately 30x25mm of screen area is allocated to each alarm.

Configurable alarm display

Each alarm can be individually configured according to the control logic of the installation. Different colours can be used on the screen to distinguish alarm type or priority.

Alarm acknowledgement and reset

The operator can select a flashing alarm simply by touching it on the screen or by using the navigation arrows.

Once an alarm is selected, the Accept function can be used to acknowledge it, while Reset restores the status according to the configured operating logic.

Pressing and holding an alarm field or using the Enter function opens more detailed alarm information.

Physical control buttons

LED status indicators

Separate front-panel LED indicators provide a quick overview of the main device states.

• Audio Silence – audible alarm mute status.
• Fail – fault status.
• Run – normal device operation.
• Lamp Test – indication test status.

SOE – Sequence of Events recording

The alarm terminal includes a Sequence of Events (SOE) function for recording the time of status changes.

Communication protocols

This version is intended for integration into industrial and power-system communication networks and supports several major communication protocols.

IEC 61850 integration

The terminal supports IEC 61850 Server functionality with MMS data exchange and GOOSE communication.

This enables integration into modern substation automation systems and allows status and alarm information to be transferred to a higher-level control or SCADA system.

DNP3.0 and Modbus RTU

DNP3.0 support allows the terminal to be used in power-system telecontrol and remote-control systems, while Modbus RTU enables integration into standard industrial automation systems.

IRIG-B time synchronisation

The integrated time synchronisation port supports the IRIG-B protocol. Accurate time synchronisation is particularly important when SOE recording is used and event timestamps from several devices need to be compared.

Networked system

Devices can be connected into a network, allowing information and alarms from other terminals connected to the same network to be viewed on one terminal, depending on the system configuration.

An integrated WEB-type viewing function is used for this purpose, allowing information from other system devices to be accessed from one terminal.

Ethernet and serial interfaces

Audible alarm indication

The terminal has an integrated audible alarm function. The operator can mute the audible signal using the Audio Silence function without clearing the alarm displayed on the screen.

This makes it possible to separate the alarm's audible notification, acknowledgement and final reset.

Display ON/OFF modes

Display operation can be configured according to the requirements of the control centre.

• Switch on by touching the screen or pressing a button
• Switch off after 10 minutes
• Switch off after 30 minutes
• Switch on when an alarm occurs
• Continuous display operation
