Kentec expands Sigma ZXT compliance with UL 864 listing

Kentec panel gains UL 864 listing

Kentec has announced that its Sigma ZXT control panel has achieved an Underwriters Laboratories (UL) listing to the UL 864 10th edition standard, allowing the platform to support compliant fire detection and suppression systems in global markets.

Kentec said the listing applies to a panel designed for early-warning fire detection and suppression systems across the Americas, the Middle East and Southeast Asia.

The Sigma ZXT builds on the company’s Sigma A-XT range with additional features and compliance with the latest standards.

It can be configured with dual extinguishing outputs to support main and reserve cylinders, helping reduce downtime after a release.

A dynamic LCD display provides real-time system status using green, red, blue and amber indication for conditions including fire, faults and releasing stages.

The panel can also store 1,000 event logs in a downloadable record for diagnostics and investigation.

Technical details of the Sigma ZXT

Kentec said the panel is suited to high-risk applications including battery energy storage systems (BESS), where conditions that could lead to thermal runaway and fire need to be identified quickly.

Three initiating device circuits can be configured for coincidence activation so extinguishant release only occurs after confirmation of a fire event.

Three notification appliance circuits support horns, strobes and horn strobe devices from multiple suppliers, with patterns that indicate different stages of extinguishant release.

Six programmable volt-free relay outputs and two programmable inputs allow site-specific function control.

Remote indication and control can be provided through Sigma ZSi Status Units, with up to seven units connected on a monitored RS485 Data Bus.

Additional fixed-function relay outputs can be added through up to seven Sigma ZXT UL Ancillary Boards.

Kentec outlines market use

Derrick Hall, director of sales at Kentec Electronics, said: “Achieving UL certification for the Sigma ZXT is a major step forward for Kentec.

“It allows us to bring a proven and trusted platform to a much wider global audience, particularly in regions where UL compliance is essential.

“Over the last five years, the ZXT has already demonstrated its reliability in the field.

“This certification ensures customers in new markets can benefit from the same high standards of performance and safety.

“As industries such as BESS continue to expand, the need for intelligent, early warning fire detection and releasing of fire suppression agents has never been greater.

“The ZXT platform provides a powerful solution to help protect both assets and operations.”
