GIC has introduced Alarm Annunciators with the most advanced features. With increasing automation at every stage in a process control system, Alarm Annunciators play a vital role in immediate fault recognition by providing instant visual and audible alarms to protect valuable equipments. However simple or complex the alarm requirement, GIC Alarm Annunciators will provide the most cost effective solution.

Features:

• Standard models available from 2 to 32 windows

• Choice of 3 window sizes (Small, Medium, Large)

• Available in six window colours – Red, Yellow, Blue, Green, Amber and White

• Optically isolated fault inputs with wide fault input voltage range (12V – 240V AC/DC +/-10%)

• Field selection for NO/NC fault input contacts, grouping of alarms, window size configuration

• Space saving due to lower depth of only 100mm

• Integral push buttons for Test, Acknowledge, Mute and Reset operations

• Four SPDT relay outputs (2 for grouping, 1 for external hooter,1 for ring back sequence) •

Low power, super bright White LEDs for window illumination

• Replaceable windows and window legends

• Low power consumption of 0.5 W per window

• 6 Field selectable operation sequences as per ISA standard

• Integral buzzer for audible alarm output of 90 dB

• Communication interface with RS485 Modbus RTU protocol, and

• EMI/EMC compliant as per IEC standards.

Whenever there is a change of input contacts from Normally Open to Close or from Normally Close to Open position, annunciator changes from rest condition to 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 alarm annunciator has four programmable keys for Mute, Acknowledge, Reset & Test function. On pressing the Mute key the internal buzzer can be deactivated. Acknowledge key is used to accept the fault condition, Reset key enables to reset the alarm annunciator to its default state and Test key helps to perform the complete test of the system.
