Kentec Sigma ZXT Installation Manual

The Sigma ZXT Installation Manual covers physical installation and commissioning of the Kentec Sigma ZXT — the single-area extinguishant control panel with integrated operator interface. The ZXT sits between the basic A-XT and the larger multi-area XT in the Kentec extinguishant range.

What the manual covers

• Cabinet mounting and AC mains wiring
• Battery sizing for the suppression standby requirement
• Cross-zoned detection circuit wiring
• Manual release and abort switch wiring
• Pre-discharge audible/visual warning circuits
• Discharge solenoid output
• Discharge confirmation feedback monitoring
• Lockout switch for maintenance
• Integration with main fire alarm panel via volt-free contacts
• EN 12094-1 compliance notes

Who should use this manual

This manual is for fire suppression commissioning engineers installing Sigma ZXT panels. The ZXT is straightforward compared to the multi-area Sigma XT but still requires suppression-specific competence.
