Sigma XT Ancillary Board - S588
There is sometimes a requirement to extend
signals from the extinguishing system for
additional plant control or other signaling
applications such as interfaces to BMS systems
or house fire alarm systems.
Sigma XT is equipped with a selection of volt
free contacts which are often adequate for
this purpose. For applications that require
more outputs from the system, the Sigma XT
ancillary board is available.
Up to seven ancillary boards may be
connected to the status unit serial bus to
provide distributed control and signaling
at multiple locations if required.

signals to remote locations up to 1200 metres
from the control panel using only two wires
(four if powered by the main panel).
