The EN54-2/4 compliant fire detection section connects to the EN12094-1 compliant extinguishing control modules via a serial link that allows secure, bi-directional transfer of data between the two.

Sigma XT+ modules can be mounted remotely in separate enclosures and connected to Sigma CP panels via this serial interface to provide central fire detection and control with distributed extinguishing systems. Modules can also be mounted separately from fire detection and control equipment and activated by addressable output modules or volt free contacts from other systems via two monitored activation inputs.

The fire detection part of the system has all of the benefits of the Sigma CP range with its many, easily accessed configuration options and compatibility with a wide range of detection devices.

The Sigma XT+ extinguishing modules set a new benchmark for extinguishing control panels. Each module is controlled by its own powerful microcontroller bringing intelligence and versatility to multi area extinguishing systems for the first time.

Sigma XT+ modules have inputs and outputs to cover all system requirements including individual, monitored first and second stage alarms and dual extinguishing outputs. The extinguishing outputs can be configured to operate together or as main and reserve for essential back up following a discharge. They can also be individually calibrated to provide true open and short circuit monitoring through pyrotechnic actuators or a wide range of solenoids.
