Specifications of the Fire Brigade Call Station:
The following describes the functionality of the DTA as fire brigade call station.
The fire brigade call station DTA-F is a variation of each of the standard call stations
DTA-012 / 030 / 048 / 066 / 084.
In respect to the modes of operation, intercom and public address, it is identical in
terms of functionality with the standard DTA call stations.
Added to this was the option of monitoring the functionality of the microphone, as
required in the standard, VDE 0828 / DIN EN 60849 (Emergency Sound Systems). For
this the call station is fitted in the factory with a special gooseneck microphone and the
monitoring functions.
This way, in respect to cyclical monitoring of the LF transmission path, call station
outage can be detected and signalled on time.
ICS Programming:
Busy signals, voice acknowledgments and call signals are indicated by the LEDs. The
display and blink behaviour of the LEDs can be programmed with the system software
ICS of the DVS-21.
To connect the call station to the DVS-
21, a 4NSA module with 7 kHz
monitoring attachment (order no. 2.301)
is required.
To activate the “fire brigade call station”
functionality it is necessary to activate LF
monitoring in the configuration window
for the 4NSA module.
The monitoring interval can be specified
when LF monitoring is active.
