Kentec Sigma XT+ Multi-Area Extinguishant Control Panel
Summary
The Kentec Sigma XT+ Multi-Area Extinguishant Control Panels represent the pinnacle of fire suppression technology, providing comprehensive multi-zone protection for complex installations. Fully complying with EN12094-1, EN54-2 and EN54-4 standards, these sophisticated control panels offer unparalleled flexibility with support for up to 8 zones of conventional detection and up to 4 independent extinguishant areas.
Each extinguishant area features dual outputs that can be configured for main/reserve operation, ensuring maximum system reliability and redundancy. The panels provide comprehensive stage control with first and second stage sounder outputs, volt-free changeover contacts, and individual area control capabilities. Advanced features include programmable extinguishant delays, countdown indicators showing time until release in seconds, and extensive remote monitoring capabilities.
The system’s versatility extends beyond basic control functions, with each extinguishant area supporting up to 7 serially connected Sigma Si status indication and control units via simple 4-core cabling. Stand-alone extinguishant control units are also available with 2 monitored inputs for integration with remote fire detection control panels or addressable modules, making the Sigma XT+ suitable for both standalone and integrated fire protection systems.

FAQ
How many extinguishant areas can the Sigma XT+ control?
The Sigma XT+ range supports between 1 and 4 extinguishant areas depending on the model selected. Each area operates independently with its own set of inputs, outputs, and control functions, allowing for comprehensive multi-zone fire suppression systems.
What is the main/reserve configuration feature?
Each extinguishant area features dual extinguishant outputs that can be configured for main/reserve operation. This provides system redundancy where the reserve system automatically activates if the primary extinguishant system fails, ensuring continuous fire protection.
How many detection zones are available?
The system supports 2, 4, or 8 detection zones depending on the model variant. Each zone can accommodate typically 20 detectors and includes comprehensive monitoring for open and short circuit conditions.
Can remote status units be connected to each area?
Yes, each extinguishant area can support up to 7 serially connected Sigma Si status indication and control units via a simple 4-core cable connection. This allows comprehensive remote monitoring and control throughout the protected facility.
What expansion options are available?
The system’s versatility can be enhanced by fitting up to 7 Sigma CP Ancillary boards (K580) or Sigma CP Sounder boards (K461) to the RS485 serial bus, providing additional relay outputs and sounder circuits as required.
How does the countdown feature work?
Each extinguishant area features a countdown indicator that displays the time remaining until extinguishant release in seconds. The extinguishant delays are programmable from 0 to 60 seconds, with release duration adjustable from 60 to 300 seconds.
