The RF Interface M400RFE-AS 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 at the RF interface by
using built-in keys. For each radio component the recei-
ver 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 comprises an integrated power unit
and can accommodate a stand-by battery 12V/7Ah. It is
also possible to use an external power supply.
