extinguishant sigma xt

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.

Kentec Sigma ZXT Quick Start Guide

The Sigma ZXT Quick Start Guide is the rapid commissioning checklist for engineers familiar with the Kentec extinguishant range. It condenses the full installation manual into a fast-track step-by-step workflow for typical single-area suppression release installations.

What the manual covers

  • Pre-power-on physical install checklist
  • Cross-zoned detection circuit verification
  • Manual release and abort switch test sequence
  • Pre-discharge sounder verification
  • Discharge solenoid wiring and isolation for commissioning
  • Lockout switch verification
  • Final acceptance test workflow
  • Common commissioning faults and recovery

Who should use this manual

This manual is for experienced suppression commissioning engineers who have commissioned ZXT panels before. Engineers new to suppression systems should start with the full ZXT Installation Manual and ideally with structured suppression training.

Why suppression commissioning is special

Suppression panels include final-element outputs (discharge solenoids) that should not fire during commissioning. The quick start guide includes specific isolation steps for the discharge output that must be followed to prevent inadvertent agent release during testing.

Kentec Sigma ZXT-Si Datasheet

The Sigma ZXT-Si Datasheet covers the technical specifications and ordering information for the Sigma ZXT-Si variant of the Kentec extinguishant control panel range. The ZXT-Si is a self-contained variant of the ZXT platform with additional integrated features.

What the datasheet covers

  • Mechanical specifications: cabinet dimensions, weight, IP rating
  • Electrical specifications: AC mains, battery, current consumption
  • Detection circuit specifications and supported devices
  • Sounder and beacon circuit ratings
  • Discharge solenoid output ratings
  • Compliance certifications (EN 12094-1)
  • Operating temperature and environmental ratings
  • Part numbers and ordering codes

Who should use this datasheet

This datasheet is for fire suppression system designers and specifiers selecting between ZXT variants for a specific installation. It is the technical reference for matching the panel capability to the protected area requirements.

Selecting the right ZXT variant

The standard ZXT and the ZXT-Si differ in certain integrated features and certifications. Specifiers should review both datasheets and the relevant operation manuals before final selection — the wrong variant can lead to compliance issues at sign-off.
