Sertel Goose Annunciator is a persistent surveillance system deployed to watch and sense devices of many types and functions. T-AA-300-GSE-BXXX can be configured to provide the best solution for various size and complex alarm scheme.

MOST Striking Feature is that this system can take in Soft Inputs from Horizontal GOOSE packets in a SAS Substation network. On Feeding the ICD files for various IEDs the Inputs can be configured for the corresponding channels. Wide range of window size, colors could be accustomed as required. Each individual alarm is fully programmable from the front end using the integrated programming module. This allows the user to select many different features giving thousands of possible combinations.

Numerous relay outputs are included as standard output to connect to external equipment and individual repeat relays or communications can be supplied as an optional output. Multiple back lit windows are provided, each engraved with the name of the process alarm.


The annunciation unit is built with panel mountable and wall mountable types which can be supplied as per requirement. In front side, removable Legend display Facias are installed in A4 size standard sheets. In the rear side, the input connections and power supply connections are provided.

Input card and the mother board cards are completely isolated. Input cards have connection to the input field contacts, power supply unit and external push button connections. All inputs are completely isolated from the mother board. This input card can serve from 8 to 1000 channels by cascading them.

Card extensions are provided for easy increase in channels by creating a daisy-chain network of Input, Output, Repeat Relay cards. The alarm contact relays and hooter contacts are present in the input card.

Each channel can be configured for Trip / Non-trip Alarm and N.O. / N.C. Input configurations. The whole unit has self- diagnostic features, power failure management and other redundancy features. Power failure indications are provided in the front side of the annunciator.
