4.4 Further connection possibilities
Routing the USB connection out
To ensure that the USB connection on the printed board can
be accessed without opening the housing, a USB housing
socket with cable and connector for installation in the hous-
ing of the control unit can be ordered from KESSEL (art. no.
28785).
TeleControl GSM modem
Mount the TeleControl modem (art. no. 28792) as described
in the corresponding installation instructions 434-033.
Potential-free contact
A potential-free contact can be activated at the control unit
as an add-on function, available as an accessory (art. no.
80077). This applies to all control units produced from 2017.
It can then be used to connect the unit to the building con-
trol system or to other accessories, for example, the warning
beacon (art. no. 97715).
