XT

Extinguishant

Control Panel

Sigma XT is a new generation extinguishant releasing panel which is fully compliant with

European standard BS

EN12094-1.

(Fixed firefighting systems

– components for gas extinguishing systems).

The simple, programmable configuration options and easy to install construction make Sigma XT panels the ideal choice for small to medium sized systems using all extinguishant agents.

Product Overview

Designed and manufactured to the highest standards in a quality controlled environment and with European EN12094-1 approvals, the Sigma

XT extinguishant releasing panel offers outstanding value and performance for all small to medium fixed firefighting installations.

With three detection zones as standard, extinguishant release can be configured to activate from any combination of detection zone inputs to allow (among other combinations) any two from three type activations such as would be required for detection in ceiling void, room and floor void applications.

The extensive configuration options of the Sigma

XT allow the functionality of the system to be extensively modified while still complying with the requirements of the controlling standard for the equipment (EN12094-1).

The panel contains a large LED display to enable easy configuration and control which also displays the time remaining until extinguishant release for added user safety.

The countdown timer is duplicated on up to seven remote status units to provide local indication of the extinguishant system status.

With all of the electronics mounted on a single, easily removable, steel plate Sigma XT panels are both robust and easy to install.

Sigma XT is supplied in an enclosure that matches the design and colour of the Sigma CP range.
