Overview

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

With three initiation circuits as standard, release can be configured to activate from any combination of detection zone inputs to allow (among other combinations) any two from three types of activations. For example, as would be required for detection in ceiling void, room and floor void applications. The configuration options of the Sigma A-XT allow the functionality of the system to be extensively modified. The panel contains a large LED display
to enable easy configuration and control which also displays the time remaining TM until release for added user safety.

The countdown timer is duplicated on up to seven remote status units to provide local indication of the system status. With all the electronics mounted on a single, easily removable, steel plate, Sigma A-XT panels are both robust and easy to install. Sigma A-XT is supplied in an enclosure that matches the design and colour of the Elite RS range and is available in red or grey.
