Description
Key Features:
- Multiple Channels: Alarm annunciators often support multiple input channels, allowing them to monitor various signals from different parts of a system. Each channel corresponds to a specific alarm point.
- Visual Indicators: LED indicators that light up or change color when an alarm condition is detected.
- Audible Alarms: Built-in buzzers or horns provide an audible alert to ensure that operators are aware of the alarm.
- Acknowledge and Silence Functions: Operators can acknowledge an alarm to confirm that they have seen it and silence the audible alarm while the visual indicator remains active until the fault is resolved.
- Sequence of Events Recording (SOER): Advanced annunciators can record the sequence of events leading up to and following an alarm, providing valuable data for troubleshooting and analysis.
- Communications Interfaces: Modern annunciators includes interfaces for integration with other systems, such as SCADA (Supervisory Control and Data Acquisition) systems, via protocols like Modbus and Ethernet etc
- Redundancy and Reliability: High-reliability annunciators are designed with redundancy features to ensure continuous operation, even in the event of a component failure.
- Environmentally Robust: Built to withstand harsh conditions, including temperature extremes, dust, moisture, and vibration.
