GX_R_AUX
The GX_R_AUX is the digital BACS version of the former CON_R_AUX for the CS121
series, which can be connected directly to the CS141. This device offers switching
relays as Output and dry contacts as Input to connect external devices to the
BACS/CS141 system.
The overall configuration process is similar, but the GX_R_AUX provides some
advantages like the option to integrate up to 4 of these devices into one BACS bus -
this will allow up to 16 inputs and outputs in total.
Due to the fact they are freely configurable, that can be used to switch and monitor
many functions including other systems.
The GX_R_AUX devices are designed to be used a modular. They do not need to be
installed all together at a single place - Install or move them during maintenance work
anywhere within the installation inside the BACS bus.
Due to the fact the GX_R_AUX is supplied with the necessary operating voltage via the BACS bus cabling, there are no further live
cables that need to be installed separately*.
Thanks to the modular concept, the GX_R_AUX is an optional accessory to extend the scope of functions and activities of your BACS
installation by many additional possibilities and can be used for both – the BACS installation as well as advanced CS141 configuration
to communicate with child- and parent surveillance and monitoring systems as well as to trigger and monitor third-party devices. All you
need to do is to put the GX_R_AUX to its own little BACS strain.
Note
The GX_R_AUX makes it possible to configure battery systems according to the US standard "International Fire Code IFC 608.3". This
standard defines, in case of a malfunction in coming with a possible impending Thermal Runaway threat, the batteries have to be
completely isolated automatically. The use of the GX_R_AUX allows activation of battery separators and thus meets the requirements of
the US Standard International Fire Code IFC 608.3. In case of an impending Thermal Runaway, the GX_R_AUX can trigger
battery separators or send an opening signal through alarm contacts in order to disconnect the battery system from the charger so the
batteries cannot heat up anymore.

Pin 11 – 14: Alternative BACS Bus
In some cases, it may be necessary to connect BACS devices directly via contacts. To provide this additional function, ports 11 to 14
can be used in case of the device is not connected to the BACS bus via the "BUS 1" or "BUS 2" plug.
