Thank you for choosing 4EVAC as your solution for Voice Evacuation System.

4EVAC is manufacturer of Impact Rack-build and Compact 500 all-in-one-box Voice Evacuation

Systems. All 4EVAC Voice Alarm systems are capable of both standalone and network operation.

4EVAC Voice Alarm systems are certified in accordance with EN54-16 and EN54-4, which are

harmonized standards under Construction Products Regulation, mandatory in the European Union.

What is the 4E-SW6?

4E-SW6 is a DIN-rail mounted 100V audio matrix with 2 inputs

and 6 outputs, dedicated for both 4EVAC Compact and Impact

systems.

4E-SW6 has two 100V audio inputs (CHA, CHB) which connect

directly to amplifier outputs. 4E-SW6 expands the number of

independent loudspeaker lines with individual surveillance and

short-circuit isolator units (Loopdrive). Each loudspeaker line

can handle up to 200 W load and can be assigned as a separate individual zone. One input can

accept maximum 500 W of power, this is also the limit for total load of all 6 output lines together.

NOTE:

With IMPACT:

Multiple (N) 4E-SW6 modules can be fed in parallel from the same pair of

amplifiers, creating 2 x 6*N matrix.

With COMPACT:

Amplifier output (i.e. loudspeaker line output of Compact 500) can be

connected to maximum one 4E-SW6 module, feeding maximum 6 loudspeaker lines – outputs

of 4E-SW6.

4E-SW6 is controlled by the main system controller (Compact 500 or Impact Controller) via L-Net,

receiving in real time routing information for each output line in order to connect to channel A,

channel B or internal bus C.

Because of higher power demand routing information for each output line in order to connect to

channel A, channel B or internal bus C, compared to other L-Net devices it features additional 24V

power input. 4E-SW6 supports also redundant network link.

What is the SW6-LITE?

SW6-LITE is a special version of the SW6 that works with LoopDrive LDB

ONLY!

SW6-LITE has no ability to provide speaker line integrity. The SW6-LITE ‘sits’ in front of LDB and

provide audio zoning from amplifier (COMPACT / IMPACT) to LDB.

LoopDrive is providing the loudspeaker line surveillance.

The installation and programming of SW6-LITE is same as for SW6. The loudspeaker line

surveillance needs to be set: OFF

Where do I start?

First, make sure that you are officially allowed to access the hardware of Compact 500 & Impact

system devices.

This is usually the case if:

• you are an authorized representative of 4EVAC;

• you have been trained by 4EVAC or its authorized representative for installation, service

and commissioning of Compact 500 & Impact Voice Evacuation System.

Unauthorized hardware and/or software modifications are against the law and outside of

manufacturer’s responsibility. If you have doubts about your status and access level permissions,

please contact 4EVAC main office.

Opening device housing or tampering with network cabling is

restricted. This gives access to all interfaces, internal system

connections and sensitive hardware settings that are of high

importance to system operation mode, hardware reliability and safety

(Access Level 3 according to EN54-16, Annex A). This access level (and

higher) is strictly protected by the manufacturer and reserved only for

service personnel who is trained, approved and officially certified by the

manufacturer. Any actions carried out in Access Level 3 without

manufacturer’s explicit approval may lead to incorrect settings or

hardware damage, causing serious system malfunction, and therefore

are strictly prohibited and void manufacturer’s warranty.

Configuration settings

Settings for 4E-SW6 are included in the configuration file located on micro SD memory card

installed in the Compact 500 / Impact CONTROLLER unit.

Configuration file includes user-defined settings, such as:

a) Definition of amplifier channels connected to SW6

b) Input / output surveillance settings,

c) Zone settings

Configuration file should be prepared in 4EVAC Manager. 4EVAC Manager is GUI software running

on Windows OS. All configuration settings are explained in the manual “4EVAC Manager guide”.

NOTE:

Please make sure that configuration file is prepared with the version of 4EVAC

Manager compatible with current firmware of your Compact 500 and/or Impact system.

Hardware installation and settings

5.1.

AMP Inputs (CH A, CH B)

There are 2 inputs A and B for connecting outputs of power

amplifiers to the SW6. When one input is enabled (defined in

settings), then SW6 becomes a 1 x 6 matrix (Single channel

mode). If both inputs are enabled (in settings) then SW6

becomes 2 x 6 matrix (dual channel mode). Single/dual channel

mode is defined automatically, based on configuration settings.

Inputs can be optionally enabled with 20 kHz detection

surveillance. If enabled, SW6 will trigger a fault if 20 kHz signal is

not detected at the monitored input.

Both inputs A and B can accept 100V audio signal of maximum 500 W each.

Amplifier CHA / CHB input connector is doubled (direct internal parallel connection) for convenient

daisy-chaining of multiple SW6 modules using the same amplifier.

5.1.1

Single channel mode

In single channel mode 4E-SW6 works as 1x6 matrix. Only one audio signal can be distributed over

6 output zones. Each output zone of SW6 can be either transmitting signal from input A, or remain

silent (internal surveillance bus). In case of multiple sources attempting to occupy channel A, system

controller (Compact or Impact) transmits the top priority signal, while the other signals are

suspended.

In this mode 4E-SW6 does not provide built-in backup amplifier function (see chapter “Backup

amplifier function”), because only one amplifier is physically connected to 4E-SW6. If 4E-SW6 is

used in single channel mode in combination with Compact 500 system, then dedicated backup

amplifier board must be used in Compact, if backup function is required.

Compact 500 is capable to operate with max. 6 x 4E-SW6 in single channel mode, each fed by one

of 6 amplifier channels available in Compact. Maximum total load in this case is 6 x 100W (100W

per 4E-SW6), maximum number of individual zones is 36.

5.1.2

Dual channel mode

In dual channel mode 4E-SW6 works as 2x6 matrix. Two independent audio signals can be

distributed over 6 output zones. Each output zone of SW6 can be either transmitting signal from

input A, or input B, or remain silent (internal surveillance bus). In case of more than 2 sources

attempting to occupy channels A and B, system controller (Compact or Impact) transmits the top

priority signals, while the other signals are suspended.

In this mode 4E-SW6 provides built-in backup amplifier function (see chapter “Backup amplifier

function”), because two amplifiers are physically connected to 4E-SW6.

Compact 500 is capable to operate with max. 3 x 4E-SW6 in dual channel mode, each fed by 2 of

6 amplifier channels available in Compact. Maximum total load in this case is 3 x 100W (100W per

4E-SW6), maximum number of individual zones is 18.

5.2.

Speaker outputs (Line 1 – 6)

There are 6 independent loudspeaker outputs. Single output can

handle from 20W to maximum 200W load. Total maximum load

of all 6 lines is limited to 500W (equal to maximum input rating).

Every combination of loudspeaker lines may be linked to any zone

in the system, with maximum 6 zones per single SW6.

Loudspeaker lines can be individually monitored for short/open

circuit with 20kHz EOL measurement. EOL surveillance requires

calibration procedure, as described further in this manual.

5.2.1

EOL module

Loudspeaker lines must be equipped with an EOL module in order to be under stable surveillance.

EOL boards are not supplied with 4ESW6 and are available at 4EVAC as separate product.

SW6 supports surveillance of loudspeaker lines based on impedance measurement @ 20 kHz.

For reliable monitoring of speakerline use EOL board. Connect EOL board to the end of the

loudspeaker line in parallel, preferably inside the last loudspeaker on the line. EOL is not polarity-

sensitive.

Loudspeaker line with EOL module

NOTE

: EOL module features a 145°C thermal fuse, minimizing the risk of line short-

circuit under fire conditions. Exposing EOL board to temperatures exceeding 145°C will

damage EOL circuit and cause open fault of the loudspeaker line.

The purpose of EOL is to create reference load at the monitoring frequency 20kHz. With EOL

connected, monitoring of load impedance is more accurate and less sensitive to slow and long-

term impedance drift of the loudspeakers due to aging and weather conditions. It also gives

more reliable fault indication when a large number loudspeakers is placed on one long line.

5.2.2

EOL measurement calibration

Once the loudspeaker lines are connected and EOL boards mounted at the end of every line, you

can calibrate EOL measurement to currently detected impedance value @20kHz. As result of

calibration the reference impedance value is saved for every line to the internal memory of SW6.

It is highly recommended to re-calibrate the impedance measurement:

• After every modification of the loudspeaker line installation,

• After replacing power amplifier feeding the SW6 module.

NOTE

: Before calibrating impedance please check the health state of every line with an

impedance meter:

1. Check load: measure every loudspeaker line individually with impedance meter and check

if the load is as expected. During measurement lines should be disconnected from SW6.

2. Check EOL: make sure that EOL board is properly connected at the end of every

loudspeaker line. Check if the impedance setting is correct on each EOL board.

In order to start calibration, use CAL button located next to

the network port.

1. Press CAL button. If calibration is started, you will see

all LEDs start blinking yellow.

2. Release the CAL button and wait until ;

3. SW6 will indicate result of calibration on LEDs (see

chapter Indications).

If the impedance of the line is within acceptable range,

calibration should be successful. If line calibration is not successful, impedance of this line is not

acceptable. This could be caused by one of following faults:

• line is overloaded,

• line is shorted,

• line is open,

• EOL is disconnected or damaged.

5.2.3

Live monitoring of EOL impedance measurement

4EVAC Live monitoring – real time measurement of 20kHz impedance

4EVAC systems implement AC line monitoring at 20kHz with EOL. The purpose of EOL monitoring

is to detect:

- Any short circuit between + and – conductors of the loudspeaker cable, which would result

in total loss of audio signal;

- Any interruption in the loudspeaker line cable, which would result in loss of audio signal in

(part of) loudspeakers powered by that line.

Lack of reliable specifications of loudspeakers and loudspeaker cables, as well as complex nature

of combined total impedance of a loudspeaker line makes it impossible to predict or calculate

impedance at 20kHz without real measurements.

In order to effectively assess loudspeaker lines monitoring in 4EVAC systems, it is necessary to use

Live Monitoring feature of the 4EVAC Manager GUI application, where you can observe exact

impedance at 20kHz of each loudspeaker line, in real time. (More information on how to use 4EVAC

Manager you can find in 4EVAC Manager User Manual).

Live Monitoring in 4EVAC Manager GUI

In the screenshot above you can see Live monitoring window of 4E-SW6. For each output line

following parameters are displayed in real time:

•

Impedance

This is the actual 20kHz impedance measured in real time by the system. Values below 10Ω

are considered as short circuit. Values above 5kΩ are considered as open line.

•

Reference impedance

This is the reference impedance saved in system memory during impedance calibration.

•

Deviation

This is the difference between reference impedance and actually measured impedance,

expressed in %. Deviation relates directly to Tolerance setting of EOL monitoring (see

4EVAC Manager User Manual)
