Mediola 2 channel wireless/door/window contact FS20 TFK2 652-77 Data Sheet

• When using the ‘FS20 TFK’ internal contacts, the device may be mounted directly on the

door or window which is to be monitored (from here on we will refer to all installation areas
as windows for the sake of simplicity).

• When using the external contacts, the ‘FS20 TFK’ may be mounted wherever you wish; in

a hidden place, for example. A potential-free normally closed or normally open contact can
be used as an external contact.

• The installation location should be chosen taking the wireless range into account. Sufficient

distance from large metal objects (such as radiators) and electronic devices (such as
computers) should be maintained.
