Sigma Control Panel


The Sigma XT extinguishant control panels are designed to the requirements of AS7240.2, AS7240.4 and AS ISO 14520.1.

Each extinguishant module has a comprehensive set of inputs and outputs and is configurable via the panels LCD display and simple menus. 
 
The data bus cabling of the sigma warning signs and remote status units, simplifies and minimises cable requirements and maximises monitoring of these external devices.
