Free PDF manuals for the Kentec Sigma XT extinguishant control panel range — the EN 12094-1 certified gas suppression release panels from Kentec. These panels control automatic fire suppression systems using clean agents (FM-200, Novec 1230) or CO2, providing the discharge release and monitoring functions for protected areas including data centres, server rooms, switch rooms and industrial process areas.

About the Sigma XT range
The Sigma XT family is EN 12094-1 certified for fire-extinguishing system electrical components, covering the discharge release control function for gas-flooding suppression systems. Key features:
- Sigma XT — multi-area extinguishant release panel
- Sigma A-XT — single-area variant for compact installations
- Sigma ZXT — single-area extinguishant release with operator interface
- Sigma ZXT-Si — ZXT variant with additional features
- Sigma XT UL Releasing Unit — UL-listed variant for North American installations
- Manual release and abort functions
- Pre-discharge warning sounders and beacons
- Discharge confirmation monitoring
- Cross-zoning logic for false-alarm protection
Where Sigma XT panels are used
Extinguishant control panels are deployed in environments where water-based suppression cannot be used: server rooms, data halls, telecoms equipment rooms, document archives, art storage, switchgear rooms, and industrial process areas. The protected area is typically an enclosed volume that can be flooded with a clean agent or CO2 in the event of a fire.
Sigma XT integration with fire alarm systems
Sigma XT panels typically operate as a sub-system to a main fire alarm panel. Fire detection in the protected area triggers the Sigma XT discharge sequence, which includes a pre-discharge warning, abort opportunity and final release. Integration with the main fire panel is via volt-free contacts or addressable interface modules.
Fire suppression training
Commissioning extinguishant panels safely requires specific training because incorrect commissioning can lead to inadvertent discharge with significant property damage and life-safety implications. BH Courses run a dedicated fire suppression training programme covering Sigma XT range commissioning, EN 12094-1 compliance, abort sequence design and integration with main fire panels.
For multi-brand training including suppression, see the Fire Alarm Training Course.
