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?

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)
