The Audio Matrix EV-5000 is intended for use over a range of ambient temperatures from -5°C to

+55°C. During transport or storage temperatures from -20°C to +70°C are permissible. Do not

operate the EV-5000 in a damp or dusty area nor expose it to rain or to an environment, where it

may be splashed by water or other liquids. Please allow the unit sufficient time for acclimatisation

to room temperature (minimum 30 minutes) before powering up, if you bring it from a cold into a

warm environment. Do not place the product where it will be in the path of direct sunlight or near a

heater.

Check your local mains voltage before connecting the EV-5000. This device is normally set up for

an AC line voltage of 230 volts, 50 to 60 Hz.

The unit may only be operated at a power receptacle with protective earth conductor. The wires of

the mains power cord have the following colours:

GREEN and YELLOW: PE (Protective Earth)

BLUE: N (Neutral)

BROWN : L (Live)

Warning!

The protective earth conductor must never be interrupted even for test purposes! This may

be dangerous to life!

Do not block the ventilation slots of the chassis. This will cause the temperature rising and may

result in fire. Disconnect the power cord before removing the cover.

As the colours of the wires in the mains lead of this apparatus may not correspond with the

coloured markings identifying the terminals in your plug, proceed as follows:

The wire, which is coloured green and yellow, must be connected to the terminal which is marked

by the letter PE or by the safety earth symbol or coloured green and yellow. The wire, which is

coloured blue, must be connected to the terminal which is marked with the letter N or coloured

black. The wire which is coloured brown must be connected to the terminal which is marked with

the letter L or coloured red. The fuse protection in the house distribution may not exceed

16 Amperes.

If the following circumstances will occur, please immediately switch off the power and

disconnect the power supply cord. Do not try to operate the device again. Contact your

local dealer to check the unit:

n damages are visible

n the device has fallen

n the device contains loose parts or any liquid gets into the unit

n the device shows malfunctions

n smoke or strange smell is coming out of the device

n the power supply cord is damaged, such as exposure of the core, disconnection etc.

n the device has been stored for a longer period under bad conditions such as open air or in damp

rooms

n the device has been exposed to hard transport conditions like badly packing

When repairing devices with microprocessors (EV-5000, EV-PAGE and EV-REL), the general

precautions and actions reagarding electrostatic discharge have to be taken.

This appliance may only be used in accordance with its intended purpose: Audio Matrix in a public

address or voice alarm system.

6. General Information

The EV-5000 is a Public Address and Voice-Alarm Matrix, which operates all necessary

supervisionfunctions in a slim 1 unit housing according to EN 60849. You can connect several

callstations and release emergency-announcements, stored evacuation-signals, chimes and

background muisc.

All sound files are stored on a SD Flash Memory card for easy handling.

The EV-5000 is the smart choice for a wide range of applications such as schools, convenience

stores, factories, office buildings or hotels. In the minimal setup the system is working cost-effective

with only 1 main-amplifier and a backup-amplifier. In this mode it is possible to implement 4 paging

zones. It is possible to realise projects with additional relay-boards due to its 4 line outputs, or if

even more zones are required, up to 10 EV-5000 can be linked together to control up to 80

speaker zones.

The EV-5000 detects all connected components by an automatic set-up run. The identified items

are clearly shown on the display and will then be supervised completely by the system.

According to the EN 60849 standard the following documentation must be available respectively

records have to be kept:

1. User Manual

2. System Documents

3. Operation Log

4. Maintenance Record Keeping

Please refer to the mentioned standard for further details.

9. Installation

– see overview page 4 –

9.1 Power Supply

The device is designed for use with 230V AC 50 to 60 Hz mains power. Power can be switched

ON/OFF by the rear side mains power rocker switch.

A backup power providing 24V DC can be connected via a 2-pole pluggable screw terminal. The

rocker switch only breaks the mains power, not the 24V backup power. Both power sources are

monitored by the system. If during the installation run there is no backup power source connected,

the presence of the 24V DC power source is not supervised. Powering from a 24V DC source only

is not possible, since the system will generate always an error message as soon as mains power

fails, regardless what the state was during the installation run.

9.2 Connection of Power Amplifiers

Amplfier inputs have to be connected to the OUT CH1...OUT CH4 pluggable screw terminals, the

backup amplfier to the OUT SPARE connections. All outputs of the EV-5000 are transformer

coupled (balanced and floating) for trouble free operation. Therefore the cable shields have to be

connected at one end only. The following drawing shows some wiring for balanced and unbalanced

amplifier inputs:

These samples are valid for amplifiers, which are earthed by a 3-pole mains power cord and plug.

If all-insulated (double isolation, 2-pole mains power plug) amplfiers are used, which have also no

GND connection via a backup power supply, the shield must be connected on the EV-5000 side

(GND screw terminal) too.

The amplifier outputs (100V types only) are to be connected to the AMP IN1...AMP IN4 inputs and

SPARE AMP IN input respectively.

9.3 Connecting Speaker Lines

Speaker Lines are to be connected to the CH1 OUT...CH4 OUT terminals.

CAUTION!

For error free functioning of supervision, the minimum load has to be 10 Watts per zone at 22 kHz.

Please be aware that speaker impedances are frequency dependent, so each line has to draw

10 watts at 22 kHz not at 1 kHz. If it would be less, please connect a resistor 1 Kiloohm/10Watts in

parallel to the last speaker on the line. Maximum power must not exceed 800Watts/100V per zone.

9.4 Connecting Call Stations

The fireman call stations can be connected to the rear side pluggable screw terminals (EV-EVAC1,

Fire Mic1) or to the front side DIN connector (5-pole, 180°, Fire Mic2) for EV-EVAC MIC. Pin layout

is as follows:

Pins 1 + 3 = MIC capsule

Pins 4 + 5 = switch input (PTT)

Pin 2 = GND, shield

The subzone call stations EV-P4 are to be connected to the so designated pluggable screw

terminals or to the RJ45 connector. Up to about 30 EV-P4 can be connected in parallel. The RJ45

connectors pin layout is the same as the screw terminals:

1 = BUSY

2 = GND

3 = Capsule (CAP) hot

4 = Capsule (CAP) cold

5 = Key1

6 = Key2

7 = Key3

8 = Key4

The cable length with EV-EVAC1 and EV-P4 can be extended up to maximum 500 Meters. Of

course only well screened and twisted pair cable has to be used such as communications

installation cable F/UTP 4x2x0.8mm or CAT5/6. Due to analog signal type, there will be a high

frequency cut when extending cable length to more than about 200 Meters.

The EV-PAGE call stations (80 channel) are to be connected as well to pluggable screw terminals

as to a RJ45 connector. Up to 8 EV-PAGE can be connected in parallel. The RJ45 pin layout is

also the same as the screw terminals:

1 = +15V DC

2 = GND (0V[15V])

3 = RS485 +

4 = RS 485 –

5 = GND

6 = EVAC

7 = Capsule (CAP) hot

8 = Capsule (CAP) cold

Maximum cable run is 200 Meters. Only well shielded twisted pair telecommunications cable may

be used such as F/UTP 4x2x0.8 or CAT5/6. It is possible to extend the cable run up to 500 Meters,

if the DC power supply (normally 15V DC) will not drop below 14V at any call station. If so, please

add further pairs of wire in parallel to the supply leads. Here is also valid: cable runs with more than

about 200 Meters will cause a high frequency loss.

9.5 Connecting Program/Background music sources and AUX with request contact

The IN PRG cinch connector is the input for program/background music. Line sources with a 0 dBu

(=0.775B RMS) level are to be connected.

The AUX cinch connector is for line sources providing a dry contact for request such as a

spotplayer for instance. Line level has to be 0.775V RMS too. The contact must be wired to AUX

screw terminal and GND.

9.6 Further Control Inputs

To start stored alarm messages (for instance evacuation) the screw terminals EMY1 and EMY2

(against GND) can be used. The message is running as long as the control input is shorted to

GND. All wiring is monitored, this is why 2 resistors have to be added to a switch as shown below:

1

425

3

ic audio

EV-5000

EN

12

The chime (for breaks) and a stored message (for instance shop closing announcement) can be

started by an external control key (normally open, NO). The corresponding screw terminals are

designated CHIME and MSG (message). They have to be wired against GND. These control inputs

are not supervised and therefore no resistors are necessary.

9.7 Relay Contacts EMY and ERR

The dry contact designated EMY (emergency, normally open, NO) is active during an

announcement via a fireman call station or during a stored alarm anouncement (evacuation) run.

The EMY dry contacts are useful for energising priority override relays for instance. Furthermore

this contact is active on the installation run.

An ERR called dry contact (Error, normally open, NO) is active on all error messages from the

system. This is intended to control indicator lamps for instance.

9.8 Cascading, Master/Slave Operation

If the amount of zones is not adequate, Master/Slave systems can be configured. Up to 10 units

(1 Master and up to 9 Slaves) can be cscaded by 2 RJ45 connectors (CASCADE) in each unit for

simple looping in.

CAUTION!

Each unit (Master and Slave) must have its own backup amplifier. The backup amps ouput

power must be the same as the most powerful operational amplifier.

All EV-PAGE callstations are to be connected only to the master unit and not to any slave.

However the EV-P4 callstations can be connected to both Master and Slave units and will call to

zones connected to each unit only. It is not possible to make calls via EV-P4 from Slave to Master,

from Slave to Slave or vice versa. Of course EV-PAGE can call in all zones.

If AUX-input, Message and Chime (for breaks) should be started in all systems at a time, the

control contacts and the AUX audio signal inputs have to be paralleled. For activating stored

emergency announcements in Slaves, a separate alarm switch (with resistors for monitoring) has

to be installed each. As an alarm announcement is started in a Master unit, the Slaves will start as

well in zones and with levels as programmed in the particular Slave unit and with sound files as

recorded on their SD-card.

All error messages coming from Slaves will be shown globally in the Master unit as „SLAVE

SYSTEM“ and in the respective Slave with there detected details. Errors coming from a Master unit

will not be shown in Slaves.

The maximum length of the interconnection cable is limited on a few meters only, that is to say all

units have to be mounted into the same rack.

Each unit can be configured as Master and Slave by setting internal jumpers. If one unit only is

used, it has to be jumpered as a Master. Please find below two images, which show Master and

Slave configuration. The yellow arrows point at jumpers to be set, whereas the yellow rectangles

indicate pins which will stay open.

10. Setting up the System

After having assembled all components ready for use, the input sensivity of all power amplifiers

have to be adjusted to 0 dBU (= 0.775V RMS) for 100V of output voltage. The deviation of this

must not exceed ± 3 dB, that is to say the input sensivity has to be within 549 to 1095 Millivolts

RMS for 100V of output voltage.

Very Important!

After that, the installation run has to be started under full operational condition of all

components ( = all wiring completed, all power switches ON) in the system as follows:

Press the PROGRAM key

Press Key T3

Enter password = 3x pressing PROGRAM key consecutively

Press again key T3

As to be seen in the display, the installation run will start. If Slave units are present, these devices

will start their installation run at the same time, but the run can also be started separately for each

Slave in the same way. All connected components will be detected, shown in the display of the

central unit and installed.

After accomplishing the installation process, the following components are supervised:

EV-EVAC1, EV-EVAC MIC, the EV-PAGE cables in case of allocated address, alarm control

switches, power amplifiers, speaker lines, mains- and battery voltage.

If for instance an amplifiers fails, within 100 seconds there will be an acoustical warning (buzzer,

siren) and the error is indicated in the display. The backup amplifier will automatically be switched

in place of the defective operational amplifier – both input and output.

When not starting the installation run, no monitoring will take place and some of the system

components will not function.

To stop sounding the siren press the PROGRAM key, then key T2 (reset) and after that key T1

(= siren OFF). After having repaired the defective amplifier, a reset has to be made. In order to do

so, press the PROGRAM key again, then key T2 and once again T2 (LINE RLAYS). The error will

be resetted, the before faulty amplifier will be switched back to normal operation.

11. Programming the central unit EV-5000

When switching ON the unit, the version number is shown

in the display for a short time,

then the following screen appears:

This means on LINE1 (zone1) background music is switched ON

and the system works without any errors = OK.

11.1 User adjustable parameters

By pressing key T1 to T4 the background music status is indicated. If after the LINE-colon only

space characters are to be seen, background music for that zone is switched OFF.

The following user definable volume levels can be adjusted by the VOL key:

Music

Music MA (music master)

Chime

Message

AUX

By means of the UP / DOWN keys all volumes are to be modified. If the display shows something

like - - , the related sound source is switched OFF. The switch OFF function is only available in the

so called programming menu (described later) and thus not to be altered by a user. When for a

certain amount of time no key is operated, the display will fall back automatically to the opening

menu.

separately for all 4 line outputs.

T3 Installation Run

After pressing T3 the installation run is executed. All connected operational components of

the system will be detected and installed. The parts of the system to be supervised are then

permanently checked for malfunction.

T4 Programming audio outputs and line relays

After pushing T4, the following display will appear:

Pressing T2 generates the following screen for

programming 80-channel callstations:

For pressing T1 (Alarm1, Alarm2, Message [MSG],

Chime, AUX, Fire MIC) and T3 (sub zone callstations

EV-P4) the same procedure is effective.

By pressing T1 the call key number will be raised,

GC (= group call), zone 01, 02, 03,...and so on.

By T3 the related audio outputs were selected and

by T4 the line relays.

Pressing T3 thereafter the following screen will appear:

This means here that all 4 audio outputs to amplifiers

will be activated. By T3 single outputs were selected

and T4 will set or clear them.

Pressing T4 the following screen appears:

Here it is defined, which of the 4 line relays are

activated.

Caution!

In a standard configuration as shown on page 4, the line relays have to be cleared – no

numbers set. This will continue backgroundmusic on the not adressed zones during an

announcement.

In the following special examples 12.1 and 12.2, programming has to be done different

according to the requirements of these configurations. Because of supervision, here

the line relays have to be programmed inverse, that is to say in zones, in which a call

should go, the relays stay not energised. In zones, where the call should not be

heard, the relays will be energised and so switch these zones OFF. For programming

line relays this means, that always relays have to be activated, which have to switch

OFF zones. In the screen shown above the call will sound in all 4 zones.

By programming each single key of the callstations individually with audio and relay

switch functions, it is possible to generate single call and any combination of zones for

group calls and all call. When using EV-REL relay cards, those have to be programmed

additionally by means of their DIP-switches – see chapter 21 EV-REL.

The subzone callstations EV-P4 cannot be used together with EV-REL relay

cards.

Pressing the PROGRAM key will always return to the previous menu.

12. Special Setups

12.1 Sample configuration with one amplifier driving 3 zones

In this sample two operational and one backup (spare) amplifier are applied. Please keep in mind,

if a call goes to zone 2,3 or 4 the background music will be stopped in all these zones. Of course

zone 1 will not be affected.

Programming for distributing a call in zone 3 for instance shall be executed as follows:

Activate audio on CH2, on all other channels audio has to be deactivated.

Energise relays 2 and 4 as a call goes to zone 3.

As already mentioned, relays have to be activated, which must switch OFF zones. In principle the

same is valid for emergency announcements or inhouse messages (MSG) for instance.

During a call, switched OFF zone speaker lines were connected to the backup amplifier by the line

relays. The backup amplifier provides for the check tone too, so that switched OFF zones are

monitored permanently.

12.2 Sample configuration with several power amplifiers connected to one audio output

In the above sample several amplifiers are connected to one of the audio outputs

(OUT CH1...OUT CH4).

The system will of course detect only one joint amplifier, but the supervising functions will be

maintained. If one of the operational amplifiers fails, it will be replaced automatically by the backup

amplifier.

13. Functions when connecting a Personal Computer

With a PC it is possible to display comfortably all programming and adjustments without checking

all menus and submenus with the exception of item 5 and 7 below. Therefore no special software

is needed, a simple terminal software such as Windows Hyperterminal will do. First a PC COM-

port is to be connected to the RS232 port of the EV-5000 via a null-modem cable (reversed). Start

the terminal software and ajust the following parameters:

Bits per second 9600

Data bits 8

Parity none

Stop bits 1

Protocol none

To call for the function menu enter „i“ – without the quotation marks of course. The following screen

appears:
