Introduction
This section briefly describes the functionality of the APM/ARU/ AVD
paging system.
he Audac Paging System was developed as a simple, flexible solution for evacuation and
paging systems.
APM Paging Table:
This table microphone with zone-selection is equipped with a digital audio memory which allows
storing all necessary “gong” signals.
The gooseneck microphone is equipped with a electret capsule with cardioïd sound pattern. A
built-in Compressor/Limiter with Automatic Gain Control controls the output level of the unit.
There’s also an indication on the front plate, to give the person who’s talking an impression of his
voice level.
The complete operation, from microphone till output including all digital parts, is guarded. In case
of malfunction, there is a fault-indication. This is to make sure that when there is an emergency
call, the message arrives at the listeners.
When there are several paging units placed in a bus-structure, you can configure them with
different priority levels. The status of the audio-bus is indicated on the front panel (enable led . All
these configurations can be made in a very simple way with the free software tool “AUDAC
CONFIGURATION MANAGER”. This tool can be downloaded for free on the AUDAC
website (www.audac.be .
There are 4 basic models:
- APM 01: Paging Unit just for General announcements.
- APM 04: Paging Unit with 4 Zone Buttons, “Select All”-, “Clear”- and “Talk”-button.
- APM 08: Paging Unit with 8 Zone Buttons, “Select All”-, “Clear”- and “Talk”-button.
- APM 16: Paging Unit with 16 Zone Buttons, “Select All”-, “Clear”- and “Talk”-button.
The lower function buttons are standard programmed with following functions: a “Select All”
button to activate all Paging Zones, a “Clear” button to deactivate all Paging Zones. The remaining
buttons are used for Zone-Selection or other switch-functions.
All the buttons are free programmable with the “AUDAC CONFIGURATION MANAGER”.

Zone. By pressing “Talk”, the selected Zone will be switched.
- Power U delay: This is a function for switching on/off several devices. The step-time is
adjustable on the receive/switch unit with a small trimmer.
- Pulse Relay: By pressing a button, this function will activate a relay. This relay stays activated
as long as you keep the button pressed down (Press and hold function (e.g. To open a door
with electrical door contact .
- Toggle Relay: By pressing a button, this function will activate a relay. By pressing the button
again, Toggle relay will deactivate the relay (Set-Reset function (e.g. Switching lights,… .
- Select Layer 0: Using layers (max. 3 layers makes it is possible to expand the Paging Unit. By
pressing this button, Layer 0 will be activated.
- Select Layer 1: Press this button to activate layer 1.
- Select Layer 2: Press this button to activate layer 2.
Following functions are available in “Service mode”:
- Volume U (mic. or gong): With this function button, you can increase the volume
(microphone or gong with steps of 3dB (256 steps .
- Volume Down (mic. or gong): With this function button, you can decrease the volume
(microphone or gong with steps of 3dB (256 steps .
- Select mic.: By pressing this button, you select the microphone to change its volume.
- Select gong: By pressing this button, you select the gong to change its volume.
The standard used bus protocol is RS-485, but with an extra plug-in card other bus standards are
also available (e.g. LON,… .

ARU/AVD Receive/Switch module:
The Audac ARU/AVD Receive/Switch modules are designed for use with the AUDAC
APM01/04/08/16 paging stations. The modules communicate over RS485 and have 4/8/16
relays for several switching tasks.
Following modules exist:
- ARU04: This module can switch between 2 signals (background music and Paging
Microphone and is equipped with 4 relays (4 different zones .
- ARU08: This module can switch between 2 signals (background music and Paging
Microphone and is equipped with 8 relays (8 different zones .
- ARU16: This module can switch between 2 signals (background music and Paging
Microphone and is equipped with 16 relays (16 different zones .
- AVD04: This module can switch a common signal (e.g. 24VDC to 4 different outputs.
(Activating emergency call relay, triggering power relays for curtains,… .
- AVD08: This module can switch a common signal (e.g. 24VDC to 8 different outputs.
(Activating emergency call relay, triggering power relays for curtains,… .
- AVD16: This module can switch a common signal (e.g. 24VDC to 16 different outputs.
(Activating emergency call relay, triggering power relays for curtains,… .

The ARU module:
This module was designed for switching between 2 signals (background music and Paging . There
are 4, 8 and 16 channel modules.
The ARU module was made very flexible. For example: it’s possible to use separate music sources
for each zone, or to use 1 common music source for all Paging Zones. All combinations in
between are possible. The connections which have to be made for this can be done in a very
simple way by setting “jumpers”.
In case of large installations, the ARU modules can be placed in cascade and addressed by the
Configuration Software.
The ARU module is suitable for mounting on a DIN-rail. On one side you have the “fixed
connections” (e.g. Amplifiers, … . On the other side you have the “field connections” (e.g.
Loudspeaker cables, CAT5 bus cable,… . This way of working allows a quick, proper cabling of
the system.
The AVD module:
This module was designed for switching 1 common signal to the output. There are 4, 8 and 16
channel modules.
The AVD module can be used for the following purposes:
- Activating the “Emergency Call” relay on a classic volume control. In this case, we’re going
to switch 24V DC.
- Activating power relays or teleruptors to trigger e.g. window blinds, door contacts, ...
- Power on delay: In case of heavy equipment where the turn-on current is too large (e.g. 8
amplifiers of 4000 Watts , you can switch them on in cascade. The delay time is adjustable
by a small trimmer on the AVD unit.
In case of large installations, the ARU modules can be placed in cascade and addressed by the
Configuration Software.
The AVD module is suitable for mounting on a DIN-rail. On one side you have the “fixed
connections” (e.g. Amplifiers, … . On the other side you have the “field connections” (e.g.
Loudspeaker cables, CAT5 bus cable,… . This way of working allows a quick, proper cabling of
the system.

RJ-45 pin connections
The APM/ARU/AVD Series are connected by a CAT5 cable. The units need a 24V DC power
supply. The 24V DC is connected to the ARU/AVD module. Every ARU/AVD module has 2
RJ45 sockets. By these sockets, the units are connected in a bus structure by a CAT5 cable. The
connections are as described below:
ATTENTION
The Cat5 cabling must always be “straight”. In case of self made
cabling, it must be done as described above, to make the system
work properly. To easily create a bus structure, there are “ARJ-03
splitter” modules (AUDAC . These will be described later.

Power supply
Normally, the power supply must be connected with only one ARU-, AVD- or splitter module.
The other modules of the paging network are fed through the CAT5 cable.
Ma imum rated current
The power supply’s maximum rated current must be higher than the sum of the currents of the
connected modules. If the sum exceeds 2A, it’s best to use an extra power supply instead of using
a power supply with a larger maximum rated current.
For example: an APM module uses +/-300mA, an ARU/AVD/04/08 uses +/-200mA and an
ARU16/AVD16 uses +/-400mA. Choosing the right 24V DC power supply : E.g.: We have 2x
ARU08 modules, 1x AVD16 module and 3x paging stations. This means a total of
200+200+400+300+300+300 = 1.7 Ampere at 24V DC. In this case we recommend a power
supply of at least 2A at 24V DC.
Voltage drop across the cable
In case of a large number of modules (ARU-, AVD modules and paging stations and/or large
cable distances, voltage loss across the CAT5 cable can occur. In this case some extra power
supplies must be placed in the system. These power supplies can be connected to ARU-, AVD- or
splitter modules.
Always make sure the power supply at the ARU-AVD modules and paging stations does not drop
below 16V due to voltage drop across the cable.
A simplified calculation method can be used:
Allowable voltage drop across the cable: Vdro = 8V
Average Cable resistance of UTP CAT5e cable: Rcable = 0.096 ohm/meter
Average current of a module: Iav = 0.3A
Number of modules: x
Cable length: L (in meters
Simplified formula: Vdro = L * Rcable * Iav * x
So maximum cable length L = Vdro / ( Rcable * Iav * x)
If we fill in the parameters, we get:
L = 277 / x , with x being the number of connected
modules.
For example: if we have 6 modules connected to one power supply, the maximum total cable
length of the data bus is L = 277 / 6 = 46 meters.

Getting Started
APM:
When turning the power on, the APM paging station comes into its “USER MODE”. In this
mode you have function buttons (in most cases Zone buttons, 4-8-16 , one “Select All” button,
one “Clear All” button and one “Talk” button.
When selecting a zone, the button will light up “green”. When pressing again, the green LED will
go out. You can select all Zones by pressing “Select All” and deselect all made settings by
pressing “Clear All”.
To make an announcement, you press the “Talk” button and keep it pressed down. This can only
be done in case the audio bus is free (=not in use by another paging Station. The yellow LED may
not light up .
Following actions will take place:
- All selected zones will be transmitted to the ARU/AVD receive units and the relays will
switch.
- Next step is the playing of the “gong” signal. During this, the “enable” LED flashes.
- When the “gong” signal is terminated, the “enable” LED stops flashing, the “LOW” LED
lights up and the microphone is turned on. From that moment, the announcement can
begin. The best way to speak through the microphone is from a distance of ± 5 cm, and
with a voice level that makes the “green” LED (Level = GOOD light up.
- To terminate the announcement, just release the “Talk” button.
- From that moment, you can change the selected zones for the next call.
The APM01 has just one “Talk” button, which is used to make a general announcement (All
zones . It’s also possible to specify a number of zones. This must be done in the Configuration
Manager Software Tool.

Connections ARU08
Zone output: This is the output to which signal A or B is switched for each zone. (The ground
connection should be made at the connection points of Input Channel A or B.
Input Channel A: This input is standard selected. It’s meant for connecting the signal of a music
source.
Input Channel B: To this input channel, the signal of the Paging Table(s must be connected. By
disconnecting the power (e.g. Fault , this input will be passed through.
24V DC: The system needs 24V DC power. See part “Power supply and pin configuration” for
more explanation.
Line output APM: This is the line level signal of the paging table(s . This signal must go to an
amplifier. There are different ways to do this (see next chapter .
Jumpers for Audio Routing: With these jumpers you can easily make audio routings. This saves
extra external cabling.
Analogue relay activation: This makes it possible to activate a relay simply by pulling a contact to
the ground (e.g. with pushbutton,… .
2 x RJ45 (data bus : The data bus and DC power of all modules are distributed through the CAT5
cable. To guarantee proper operation, the cabling must be “Daisy-chain”. The front and the end of
the bus must be terminated with a resistor (+-120 Ohm . This can be done on the last ARJ03-
splitter module by setting a jumper (see further in this manual .

Jumper settings for audio routing
In this example 3 jumpers are set.
The jumper on the right side above input “IN_1” connects the left channel of “IN_1.A” to the right
channel of “IN_1.A” (blue tracks . The second jumper can be used to connect the left channel of input
channel IN_1.B to the right channel of IN_1.B. Input channel A and B each have their own jumper.
The two jumpers on the right side connect “IN_7.A.right” with “IN_8.A.right” (top jumper, green tracks
and “IN_7.A.left” with ”IN_8.A.left” (second jumper, purple tracks . The third jumper can be used to
connect “IN_7.B.right to ”IN_8.B.right”, and the fourth jumper can be used to connect “IN_7.B.left” with
“IN_8.B.left”. As you can see, it’s possible to connect an input channel A or B to a previous and/or next
input channel A or B.
Lots of combinations are possible. In the example above, the A input channels are used, but it’s also
possible to use the B input channels.
