Detector Base 215-27D
The Detector Base 215-27D (fi g. C) accommodates the
radio detectors and also serves for the communication
with the RF Interface FUIF511-27D via a secured radio
protocol. The base consists of the actual detector base
and a bottom part. The actual detector base, which
contains the radio communication module and two bat-
teries (fi g. D), is attached to the bottom part by means
of a bayonet lock, thus allowing to change the batteries
with ease.
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.
The RF Interface FUIF511-27D is used for the alarm
transmission to the fi re detection control panel. In the
event of an unauthorised removal of the detector, the
base sends a fault message to the RF interface.
Regular status messages, monitoring of the battery
voltage, the low quiescent current of the inserted de-
tectors and the long life of the included batteries ensure
the high reliability of the system.
