Defining The Priority Of The Input Signals; Adjusting The Volume - Monacor PA-6240 Manual De Instrucciones

5.3.7 Telephone bell or night bell
A telephone bell or night bell may sound via the
PA system (e . g . during a round at night), if required .
1) Feed the control voltage for the bell (e . g . 8 V/
50 Hz) to the connections NIGHT RINGER (26) .
2) Press the button TEL (13) .
3) Actuate the bell and adjust the volume of the
ringing tone created by the amplifier with the
control RINGER (11) .
4) Switch the bell function on or off with the but-
ton TEL according to requirements .
Note: The bell has lowest priority .
5.3.8 Telephone switchboard
Announcements via the PA system can be repro-
duced from a telephone switchboard .
1) Feed the telephone signal (line level) to the
terminals PAGING IN (27) .
2) Adjust the volume during an announcement
with the control PAGING (12) .
Note: Telephone announcements have 3
5.3.9 Switch for announcements in all zones
For remote control of the following functions con-
nect a switch to the terminals MESSAGE FIRST
PRIORITY (28):
1 . All PA zones are switched on and set to maxi-
mum volume [as with the button ALL CALL (4)] .
2 . When using the digital message insertion PA-
1120DMT, the announcement of the memory
M 6 is automatically called . For this purpose,
connect the jumper MS 2 prior to installing the
insertion to the position "PRI TO PACK" (see
layout plan on page 48) . Thus, the announce-
ment of the memory M 6 takes first priority .
Instead of the switch, it is also possible to
connect an alarm detecting contact, e . g . for an
automatic fire alarm announcement .
3 . If the amplifier is at the same time to be switched
on by the switch or alarm detecting contact, con-
nect a diode of type 1N4007 according to fig . 7
between the upper terminal MESSAGE FIRST
PRIORITY and the left terminal POWER REM .

5.3.10 Emergency priority relays
If PA volume adjusting controls with emergency
priority relays (e . g . series ATT-3 . .PEU or ATT-5 . .PEU
from MONACOR) are inserted between the ampli-
fier and the speakers, important announcements
can also be heard at the volume "zero" .
1) For this purpose connect a desk microphone
PA-4000PTT or PA-4300PTT (chap . 5 .3 .3) .
2) Connect the emergency priority relay according
to fig . 8 to the terminals PRIORITY RELAY OUT-
PUT (47) . The output allows a load of 200 mA .
3) Set the switch PRIORITY at the microphone to
position ON (downwards) .
4) When actuating the TALK button now, the
speakers are set to maximum volume by the
relays .

5.3.11 Switch for switching on and off
The amplifier can be switched on and off by remote
control with a switch connected to the contacts
POWER REM (36) . For this purpose, the amplifier
must not be switched on with the POWER switch (19)
or not be connected to the emergency power supply .
5.3.12 Power supply and

the mains jack (35) first and then to a socket

(230 V/ 50 Hz) .
2) For continuous operation of the amplifier in case
of a possible mains failure, connect a 24 V emer-
gency power supply unit (e . g . PA-24ESP from
MONACOR) to the terminals 24 V⎓ (37) . With a
cable length of up to 6 m, a cable cross section
of 4 mm
Note:
1 . If the 24 V voltage from the emergency power supply
unit is present at the terminals 24 V⎓, the amplifier
cannot be switched off with the switch POWER (19) . In
case of a mains failure or if it is switched off, it switches
automatically to the emergency power supply .
2 . Even if the amplifier is switched off, it consumes some
power . Therefore, disconnect the mains plug from the
socket and, if necessary, disconnect the emergency
power supply unit if the amplifier will not be in oper-
ation for a longer time .
5.4 Defining the priority
A priority is assigned to all input signals . A signal of
a higher priority always covers a signal of a lower
priority when both signals are present at the ampli-
fier at the same time . Signals of the same priority

6 Operation
If the amplifier is switched off and if no 24 V voltage
Speaker
from an emergency power supply unit is present
at the terminals 24 V⎓ (37), the LED STAND-BY
(20) lights up .
1) Prior to the first switching-on, set the five level
controls (7) for the inputs 1 to 5 and the control
MASTER (17) to position zero for the time being .
2) Switch on the amplifier with the POWER switch
(19) or with a switch connected to the terminals
POWER REM (36) . The green LED STAND-BY
extinguishes and the yellow LED POWER (21)
lights up .

6.1 Adjusting the volume

1) First adjust the volume desired as a maximum
for announcements of highest priority . For this
purpose, press the button ALL CALL (4) for the
time being . According to the equipment avail-
able, make an announcement:
a) With a digital message insertion, call the
announcement from the memory M 6 via
a switch at the terminals MESSAGE FIRST
PRIORITY (28) . Set the control LEVEL at the
insertion approximately to the position 7 .
b) With a desk microphone connected to the
jack PA-4300PTT (45) or PA-4000PTT (46),
set the level control (7) of the input 1 ap-
proximately to the position 7, and make an
announcement .
c) In case of a zone paging microphone PA-
6000RC, set the level control (7) of input 2
approximately to position 7, press the button
ALL CALL (58), and make an announcement .
d) When using another microphone, set the
level control (7) of the corresponding input
approximately to position 7, and make an
announcement .
2) During an announcement, adjust the volume
with the control MASTER (17) . In case of over-
load, the red LED CLIP lights up in the level
indication (5) . Then reduce the volume with the
control MASTER .
3) To adjust the volume for normal announce-
ments, disengage the button ALL CALL again .
For this purpose, press all buttons (3) of the
individual PA zones .
4) Make an announcement as described under
Modification
item 1) b or d .
Notes:
1 . On the PA-4000PTT / PA-4300PTT, set the switch
PRIORITY to the upper position .
2 . Do not make the announcement via a PA-6000RC

the desired volume ratio to the other inputs, modify the
input sensitivity with the corresponding control GAIN .
