Alarm Annunciators

Product Description

An alarm annunciator, also known as an annunciator panel, is a crucial component in industrial control systems. It is designed to provide visual and audible alerts to operators, indicating the status of various alarm conditions in a process or facility. The alarm annunciator acts as a centralized monitoring system, displaying alarms in a clear and concise manner, and ensuring timely responses to critical events.

Working Principle Of GIC's Alarm Annunciator

Whenever there is a change of input contacts from Normally Open to Close or from Normally Close to Open position, the annunciator changes from a rest condition to an alarm condition. Hence there is an immediate recognition of fault input which will have a corresponding visual and audio alarm as per the particular selected program sequence. The base unit of the 8, 16, 32 and 48 window annunciator has four programmable keys for the Mute, Acknowledge, Reset & Test functions. On pressing the Mute key the internal buzzer can be deactivated. Acknowledge key is used to accept the fault condition, The reset key enables resetting the alarm annunciator to its default state and the Test key helps to perform the complete test of the system.
