Order name RF Interface/4Rel FUIF511-27D
The RF Interface FUIF511-27D serves for the connec-
tion of up to 32 automatic or manual radio detectors.
The interface is provided with two detector zones, each
of them having separate alarm and fault detection re-
lays. Up to 16 detectors can be assigned to each zone.
The two zones can be reported to the fi re detection
control panel as collective messages, either in conven-
tional technology or by means of auxiliary modules via
the ADM loop. After an alarm activation the RF interface
can be reset by the fi re detection control panel, via the
remote reset input.
The detectors are programmed (learned) at the RF inter-
face by using built-in keys. For each radio component
the receiver unit provides an individual LED indicator.
If necessary, several radio detection systems can be
used in the same building, in order to integrate more
than 32 radio components or to create more than 2
detector zones. A unique key, based on a choice of
several million codes, is created, which ensures the
unambiguous identifi cation of the detectors.
The RF Interface FUIF511-27D is equipped with a power
unit and can be protected against a power failure by
means of a stand-by battery 7Ah. It is also possible to
use an external power supply.
