USER MANUAL PA24FMM Monacor

Insertion Module for EmergencyAnnouncements These instructions are intended for the techni- cian installing the insertion module and for users without any specific technical knowledge. Please read the instructions carefully prior to operation and keep them for later reference. 1 Applications The module PA-24FMM is designed for installa- tion into MONACOR PA amplifiers with insertion compartment and for installation into the basic unit PA-1200EX; however, these instructions will not refer separately to the basic unit. With this module, important announcements can be made via the PA amplifier. In addition, an emergency message of up to one minute can be stored and automatically replayed when an alarm is triggered. To send an alarm to additional units, a relay with switching contact is available. This relay will also respond when the hand-held microphone is removed or when it is defective. As an addi- tional alarm feature, an integrated buzzer can be activated. 2 Operating Elements 1 Support for the hand-held microphone 2 Jack to connect the hand-held microphone 3 Volume control for microphone announce- ments 4 LED FAULT; keeps flashing when the micro- phone is not connected, when the micro- phone is defective and when an alarm is triggered

The module must be installed by skilled per- sonnel only.

The module is suitable for indoor use only. Protect it against dripping water and splash water, high air humidity and heat (admissible ambient temperature range: 0 – 40 °C).

if the module or the amplifier is visibly damaged,

2. if a defect might have occurred after the

unit was dropped or suffered a similar ac- cident,

3. if malfunctions occur.

In any case the module (with the amplifier) must be repaired by skilled personnel.

For cleaning only use a dry, soft cloth; never use water or chemicals.

No guarantee claims for the module and no liability for any resulting personal damage or material damage will be accepted if the mod- ule is used for other purposes than originally intended, if it is not correctly installed or op- erated, or if it is not repaired in an expert way. If the module is to be put out of oper- ation definitively, take it to a local recy- cling plant for a disposal which is not harmful to the environment. 4 Installing and Connecting the Module WARNING Always disconnect the mains plug of the amplifier from the socket before installing the module: Risk of electric shock!

1) Unscrew the housing cover of the amplifier.

2) On the front panel of the amplifier, unscrew

the cover plate of the insertion compartment. Remove the three-pole cable glued to the cover plate. Insert the module and fasten it. Then connect the cable to the pin connector AN07 AUDIO (see page 2). Thus, the module is supplied with ⎓ 17 V and the audio signal is sent to the amplifier.

3) To install the connection plate provided (a),

unscrew the corresponding cover plate on the rear of the amplifier or detach the corre- sponding cover plate. Insert the connection plate into the opening and fasten it with screws.

4) Connect the connection plate to the module

according to the figure on page 2.

5) Before closing the housing cover of the am-

plifier, store an emergency message (chap- ter5.1). A message can only be stored or deleted via the operating elements (b – f) on the PCB. This will prevent inadvertent dele- tion, for example.

6) For alarm triggering and thus for automatic

replay of the stored emergency message, con- nect a corresponding alarm contact (normally open contact) to the alarm input E / M of the connection plate (a).

The relay contacts FAULT MONITOR of the connection plate allow to connect additional units for alarm transmission. The power rat- ing of the relay contacts is 1 A at ⎓ 24 V or ~ 120 V.

8) If a 24 V operating voltage is required, e. g.

for an additional alarm relay, this voltage can be picked off at the terminals “24 V⎓” of the connection plate. The power rating is 40 mA. However, this 24 V voltage will only be applied during an alarm. (The alarm con- tact connected to the terminals E / M must be closed.)10 English PLAY

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 operating voltage from the amplifier. When the talk button of the microphone is pressed, the LED will be extinguished. Important: The settings described in chapters

5.1 – 5.3 can only be made when the amplifier is

open and should only be made by the installer!

corded 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 posi-

vate the alarm buzzer for the next operating step.

Short-circuit the contacts E / M of the connec- tion 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 necessary:

Keep the button ERASE (e) pressed until the LED OPERATING on the PCB is extinguished. The LED PLAY (9) keeps flashing while the message is deleted.

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 position 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 recording. While the message is recorded, both the red LED OPERATING on the PCB and the green LED PLAY (9) will light up.11 English

1) Keep the contacts E / M short-circuited.

2) Set the switch REC / PLAY (d) to the position

PLAY. Leave the switch AUTO / MANU still in the position MANU.

To start the replay, press the button PLAY(b). While the message is replayed, the LED PLAY(9) keeps flashing.

The message is reproduced via the PA system. Use the control LEVEL (10) in the section PLAY to adjust the volume of the message. When headphones are connected to the jack (11), the message will only be repro- duced via the headphones.

5.3 Settings for automatic start

Remove the short circuit of the contacts E / M: The LED FAULT stops flashing.

To activate the internal alarm buzzer when an alarm is triggered, engage the button BEEPER (5).

For a functional test, short-circuit the contacts E / M once again or trigger an alarm via the alarm contact connected: – The LED FAULT starts flashing and the alarm relay will respond. – Before the emergency message is repro- duced, a siren will sound for approx. 12sec- onds. – After the siren sound, the message will be continuously repeated until the alarm con- tact opens. Use the control LEVEL (10) to adjust the volume of the message.
