The Sigma A-Si range of status indicators provide detailed status information for Sigma A-XT releasing control equipment.
All models provide high brightness, LED indication of Manual Only, Automatic and Manual, Abort operated, Disabled, Imminent and Released conditions. Models are also available with zonal fire indicators and a common trouble indicator.
For systems where local control of the Automatic/Manual mode and or a Manual extinguishant release control are required, units are available with these controls fitted.
All models have supervised inputs for the remote connection of Automatic/ Manual mode and abort switches.
All units contain a large, LED display which shows a countdown of the time remaining until release in seconds.
The Sigma A-XT Abort switch connects to the Abort terminals of the Sigma A-XT releasing panel. Any number of Sigma A-XT Abort switches may be connected to the circuit.
The last switch must have the end of line device from the Abort circuit terminals of the Sigma A-XT releasing panel fitted across its connections to provide open and short circuit supervision.
The unit is supplied mounted to a rugged steel enclosure but may also be flush mounted to a single gang electrical box.
