M500RFE-AS und M400RFE-AS
The red Manual Call Point M400DKMR-AS (fi g. A) and
the blue Manual Call Point M400DKMB-AS with lettering
„HAUSALARM“ (fi g. B) communicate with the RF Inter-
faces M500RFE-AS or M400RFE-AS via a secured ra-
dio protocol. The detectors are especially suitable for
areas, where cabling is impossible or uneconomical.
The plastic case, which is designed in accordance with
EN 54-11/B, is provided with an integrated antenna and
accommodates the 3.6V lithium battery.
4 data channels in the frequency band 868MHz as well
as 20 channels in the frequency band 434MHz are avai-
lable for the bidirectional data transmission. The avai-
lability of the channel is checked regularly. During the
learning phase of the detector, i.e., when the detector
is registered at the radio interface, a unique key, based
on a choice of several million codes, is created, which
allows the unambiguous identifi cation of the detector.
Regular status messages, monitoring of the battery vol-
tage and the long life of the included batteries ensure
the high reliability of the system.
A built-in LED optically indicates the activated condition
of the detector. The hinged door can be opened up to
an angle of 180° and it is provided with a replaceable
pane of glass. If the detector has been activated, an
integrated locking device prevents the closing of the
door. When the door is opened, the detector sends a
fault message to the radio interface.
