- Graphical User Interface ("GUI")
In the context of a Fire Detection and Alarm System ("FDAS") or an Emergency Warning and Intercommunication System ("EWIS"), a Graphical User Interface ("GUI"), also known colloquially as a "graphics system", is a computer interface to the fire alarm or emergency warning system control panels that provides a visual and interactive means of monitoring and controlling the system's status.
The Graphical User Interface is used to display and interact (control) with conditions such as fire alarms, faults, and isolations in real-time, allowing operators to interact with the system effectively.
Graphical User Interface is often used in conjunction with a printer and large display to show generalised information such as the the zone of a fire within a building, indicating the approximate location, helping first responders to go to the source of the alarm signal more efficiently.
Key functions of a Graphical User Interface used as part of a Fire Detection and Alarm System or Emergency Warning and Intercommunication System include:
- Alarm Annunciation & Display: Visually represents location of heat, smoke and flame detectors, manual call points, water pressure switches, water flow switches, valve monitoring devices and other input signals on a building diagram or zone diagram, showing the location of each alarm device, in the context of the building.
- Fault Monitoring: Indicates system faults, such as communication issues, equipment failures, or wiring problems, allowing for quicker identification and rectification.
- Isolate Control: Allows operators to isolate specific zones or devices (e.g., detectors, sounders) in the system for maintenance or other purposes while providing a clear visual indication of isolated components.
- Real-time Updates: Provides real-time monitoring and status updates of all system components, ensuring prompt response to any issues.
- User Interaction: Offers easy-to-use, interactive controls for authorised personnel to silence alarms, reset the system, or trigger manual emergency alerts, all via an intuitive graphical layout.
- Event Logging: Records events such as alarm activations, faults, and system interactions, which can be reviewed for compliance, audits, or post-event analysis.
The Graphical User Interface enhances situational awareness, ensuring faster and more efficient response to a fire or other emergency by first responders in large or complex buildings or campus environments.
