Sigma XT+ Multi-Area Extinguishant Control Panel
The Sigma XT+ is a multi-area extinguishant control panel compliant with EN12094-1, EN54-2, and EN54-4, designed to provide robust fire protection for multiple zones and extinguishant areas. The panel supports up to 8 conventional detection zones and up to 4 extinguishant areas, while stand-alone extinguishant units are available with 2 monitored inputs for integration with remote fire detection panels or addressable modules. Each extinguishant area includes a full set of inputs and outputs, configurable via a simple programming interface.
All extinguishant areas can accommodate up to 7 serially connected Sigma Si status indication and control units or ancillary relay boards, connected using a straightforward 4-core cable. System versatility can be further enhanced by connecting up to 7 Sigma CP Ancillary boards (K580) or Sigma CP Sounder boards (K461) via the RS485 serial bus.
