Alarm Annunciators
GIC introduces Alarm Annunciators with the most advanced features. With increasing automation at every stage in a process control system, our Alarm Annunciators would play a vital role in immediate fault recognition by providing instant visual and audible alarms to protect valuable equipment. However simple or complex your alarm requirement, our Alarm Annunciators will provide the most cost-effective solution.
FEATURES
- Standard models available from 2 to 32 windows
- Choice of 3 window sizes and 6 different window colours
- Optically isolated fault inputs with wide fault input voltage range (12 – 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)
- 7 Field selectable operation sequences as per ISA standard
- Integral buzzer for audible alarm output of 90 dB
- Communication interface with RS485 Modbus RTU protocol
- Replaceable LEDs, Fast Scan, Manned / Unmanned, Supervisory Relay & Supply fail annunciation available
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.

- Legend
- Diffusor
- Window Housing
- LED with Reflector
1. For inserting legends, please remove the specific window by inserting a flat screwdriver tip (less than 5mm) into the window cover groove and lever up slightly, as indicated.
2. To separate the window and window housing, insert the tip of a flat screwdriver into one of the grooves on either of the sides as shown in the picture. Once finished with inserting the legend between diffusor and window, the whole assembly can be press fitted into the original position.
