Alarm Annunciators

Alarm annunciators display the status of alarms in industrial environments. They are common in industrial control systems, and use indicator lights that are activated when a control process exceeds its preset threshold and triggers the alarm. Alarm annunciators can be used to indicate temperatures that are too high or too low, low-pressure conditions, loss of coolant flow, and nearly any other process condition. In addition to activating the indicator light on the annunciator panel, alarm annunciators can activate alarms, horns and strobes depending upon the severity and threat of the condition that activated the alarm.
