Alarm Annunciator

An alarm annunciator is an electronic device that visually and audibly signals faults or abnormal conditions in a system. It typically features a panel with multiple indicators, each representing a specific monitored parameter. When an issue is detected, the corresponding indicator activates, alerting the operator.

 

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.
