AL2000: Alarm Annunciator

            Alarm Annunciator AL2000 This device detects, displays, and issues warnings when an alarm condition arises within a system. Control systems typically monitor various parameters-such as temperature, pressure, and motor speed-to prevent potential damage. If an abnormality occurs, the monitoring system alerts the operator so that corrective action can be taken.

            Sometimes, an alarm triggered at one point causes subsequent alarms at other points in close succession, making it difficult for operators to identify the root cause of the fault. To address this, the AL2000 is designed so that the alarm LED for the channel that triggers first flashes rapidly, while the alarm LEDs for subsequent channels flash slowly. The siren relay activates when any alarm occurs and deactivates when the "Reset" button is pressed; however, the alarm LED remains steadily lit until the fault is resolved, at which point the LED turns off.

            In cases where the alarm system requires more than 10 input channels, AL2000 units can be interconnected to expand the number of input channels.
