6.6.1 Status LEDs at the PA-4000RC

In addition to the LEDs BUSY and TALK
described above the zone-paging microphone is
equipped with the following status LEDs:
POWER / CPU ERROR (40) – lights up as soon
as the supply voltage is present and flashes
in case of a malfunction of the microproces-
sor in the PA-4000RC
MIC FAULT / LOW VOLTAGE (41) – lights up
with a failure of the microphone and flashes
if the supply voltage is too low; in case the
supply voltage is too low, the connection of
an additional power supply unit may help
( chapter 5.5.2, item 3)
SIGNAL (42) – lights up when a microphone sig-
nal is available
EMER. (47) – (one for each PA zone)
light up when an emergency microphone unit
PA-4000FMP signals an emergency situation
for the corresponding zone

6.6.2 Adjustments at the PA-4000RC

The DIP switch block (45) with the three
switches on the rear side of the desk microphone
offers the following functions:
CHIME – in position ON a chime sounds first
when pressing the TALK button (49); the
sound of the chime is the same as if activated
via a momentary pushbutton connected to
the amplifier. It can be selected in the ampli-
fier ( chapter 5.8.1)
PRIORITY – in position ON the PA-4000RC
takes priority over others without this function
activated and it is able to interrupt their
announcements
COMPRESSION – in position ON the dynamic
power of the microphone signal is attenuated
and thus distortions are reduced when talking
at high volume
7 Protective Circuits
and Fault Indication
The output amplifiers of the PA-40120 are
equipped with protective circuits against over-
load and overheating to prevent damage to the
speakers and the amplifier. In case an output
amplifier fails in this way, the 100 V speakers are
switched over by relay to a connected reserve
amplifier ( chapter 5.10). The Protect LED (3)
of the output concerned lights up and a warning
signal sounds via the internal speaker (7). In
addition, the relay FAULT (18) is switched over
and is therefore able e. g. to control an external
warning facility. Short lighting-up of all PRO-
TECT LEDs when switching on the amplifier is
usual and does not indicate any defect.
If a fault occurs at a connected emergency
microphone unit PA-4000FMP (e. g. at the hand-
held microphone of the microphone system),
likewise a warning signal sounds via the internal
speaker (7) and the relay FAULT (18) is
switched over. In addition, the LED EMER.
FAULT (3) of the PA zone the emergency micro-
phone unit is assigned to lights up.
In order to be able to hear the warning signal
via the internal speaker (7), the speaker must be
switched on [switch SPEAKER (5) engaged].
The control LEVEL (6) has no effect on the vol-
ume of the warning signal.
