2 Important Notes
The unit corresponds to all relevant directives of
the EU and is therefore marked with
•
The unit is suitable for indoor use only . Protect
it against dripping water and splash water,
high air humidity, and heat (admissible am-
bient temperature range 0 – 40 °C) .
•
For cleaning only use a dry, soft cloth, never
use chemicals or water .
•
No guarantee claims for the unit and no liabil-
ity for any resulting personal damage or mate-
rial damage will be accepted if the unit is used
for other purposes than originally intended, if
it is not correctly connected or operated, or
not repaired in an expert way .
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harm-
ful to the environment .

3 Applications

In connection with the 4-zone amplifier
PA-40120, this microphone unit serves for an-
nouncements in emergency situations, e . g . for
alarming or evacuation . It is equipped with a
hand-held microphone with function monitoring
and a recorder for recording an announcement .
The storing of the recording is non-volatile, i . e .
the recording is maintained even in case of
failure of the voltage supply . If an emergency
situation is signalled (e . g . from a fire alarm sys-
tem), after an alarm siren sound the automatic
reproduction of the recording is made via the
amplifier . At the same time the microphone unit
emits a visual and optionally an acoustic warning
signal . A failure of the microphone unit or its
microphone is also signalised to the amplifier
and displayed there .
4 Mounting
Select an optimum mounting place for operat-
ing the unit . At the distance of the mounting
holes on the rear side of the microphone unit
screw four screws or screw hooks into the wall
and suspend the microphone unit there . The
connection cables can be guided through the
opening in the rear side of the housing (30) or
through the lower side of the housing . Remove
the pre-punched plate (31) for guiding the cable
through the lower side .
5 Connections
5.1 Amplifier PA-40120
Connect the RJ45 jack OUTPUT (25) of the
microphone unit, e . g . via the supplied cable,
to the amplifier PA-40120 . The amplifier has
a connection of its own for each of the 4 PA
zones . Therefore, an emergency announcement
can only be heard in the PA zone for which the
microphone unit is connected . The possible
cable length is 1 km as a maximum .
To apply a microphone unit to several PA
zones, the output of the microphone unit has
to be connected in parallel to all desired inputs;
i . e . the conductors of the connection cables
must correspondingly be connected in parallel .
5.2 Additional power supply unit
For connection cables of more than 500 m length
the power supply via the amplifier is not suffi-
.
cient . In this case connect an additional power
supply unit with 24 V (⎓) to the jack EXT IN (29) .
The required low voltage plug has the dimen-
sions 5 .5 / 2 .1 mm (outside / inside diameter) with
any polarity .
5.3 Alarm device
An emergency situation to which the microphone
unit responds with an automatic announcement
in addition to other actions (
signalled via the connection E / M TRIGGER (27) .
Connect here an NO contact (normally open),
e . g . an alarm relay at the output of a fire alarm
system or a basic switch for manual activation .
5.4 Hand-held microphone
Connect the hand-held microphone with its plug
(24) to the jack provided for it and lock it by
fastening the cap nut .
Note: The function of the microphone is permanently
monitored by the microphone unit . A microphone
which is defective or not correctly connected is im-
mediately indicated at the microphone unit and at
the amplifier .
5.5 Audio source with line level
To record an announcement, an external audio
source with line level may be an alternative to
the hand-held microphone (e . g . for taking over
a pre-made announcement) . Connect this audio
source to the RCA jacks EXT REC INPUT (26) .
The jacks are available for stereo signal sources
as L (left) and R (right) . As the microphone unit
operates monophonically, the mono sum results
internally from the stereo signals .
