is 40 mA. However, this 24 V voltage will
only be applied during an alarm. (The
alarm contact connected to the terminals
E / M must be closed.)
9) Connect the hand-held microphone to the
jack MIC (2) and put it on its support (1).
When the microphone is removed or
when it is defective, the internal alarm
relay will respond. In addition, the alarm
buzzer will sound when the button
BEEPER (5) is engaged.
5 Operation
Switch on the amplifier; thus, the module
PA-24FMM is also switched on.
The red LED LD5 on the PCB will light up
as soon as the module is supplied with oper-
ating voltage from the amplifier. When the talk
button of the microphone is pressed, the LED
will be extinguished.
Important: The settings described in chap-
ters 5.1 – 5.3 can only be made when the
amplifier is open and should only be made by
the installer!
5.1 Deleting and
storing an emergency message
1. An emergency message can directly be
recorded via the hand-held microphone.
2. Alternatively, a prepared message (e. g.
from a PC or MP3 player) can be sent to
the RCA jacks INPUT (7).
Important: Always disconnect the micro-
phone from the PA-24FMM for this step;
otherwise, the microphone will also pick up

ambient noise, even if the talk button of the
microphone is not pressed.
1) Set the switch AUTO / MANU (c) to the
position MANU.
2) Set the switch REC /PLAY (d) to the posi-
tion REC.
3) Disengage the button BEEPER (5) to
deactivate the alarm buzzer for the next
operating step.
4) Short-circuit the contacts E / M of the con-
nection plate (a) to simulate an alarm. The
LED FAULT (4) starts flashing. This is the
only way to delete an existing message
and to store a new message!
5) To delete an existing message, if neces-
sary:
Keep the button ERASE (e) pressed until
the LED OPERATING on the PCB is extin-
guished. The LED PLAY (9) keeps flashing
while the message is deleted.
6) Before starting the recording, make an an-
nouncement via the microphone or replay
the prepared message to control the level.
Use a screwdriver to set the control LEVEL
(6) in the section RECORDING to a posi-
tion where the red LED CLIP (8) will not
light up yet. As a check, the green LED
SIG will light up at a given volume.
7) To start recording, press the button REC
(f). At the end of the announcement, press
the button REC once again to stop record-
ing. While the message is recorded, both
the red LED OPERATING on the PCB and
the green LED PLAY (9) will light up.
