Sigma Local Control Station


The Sigma-SI Status Units are designed in accordance with Australian Standard AS ISO 14520.1-2009 Gaseous fire-extinguishing systems – Physical properties and system design – General requirements (ISO 14520-1:2006, MOD).
The Status Units are designed to extend the indications and some controls of Sigma XT extinguishant control panels to other locations within the fire protection system to make operation of the system more practical within areas that have multiple access points (or doors). A maximum of seven status units may be connected to each control panel extinguishant area. All units connect to a two wire data ECU-LCS communications. Size: 186W x 132H x 55D.
