A development of its proven Sigma XT range which has been installed globally in its thousands, the Sigma ZXT provides controls and indications for a single-area extinguishing release system, enabling targeted extinguishing that limits damage and reduces cost.

Three conventional detection zones provide the alarm ‘trigger’ required to activate the release of extinguishant, and the system can be configured to release the extinguishant on an alarm from any single zone or combination of multiple zones.

Sigma ZXT continues to be backward compatible with Sigma SI status units and ancillary boards allowing easy upgrade of existing Sigma XT installations.
