Thank you for choosing 4EVAC as your Voice Evacuation System solution.
4EVAC Impact is a 19” rack format, EN54-16 certified Voice Evacuation System, dedicated to medium to
large installations. The Impact system is capable of both standalone and network operation, for a wide
selection of peripheral devices and remote extensions. 4EVAC Impact is certified in accordance with EN54-
16 and EN54-4, which are harmonized standards under the Construction Products Regulation, mandatory
in the European Union.
The 4EVAC Impact system is fully compatible with the Compact 500 Voice Evacuation System. This means
that both systems can be connected to one network, running the same protocol in peer-to-peer
architecture, operating within the same space of voice evacuation zones, sharing the same audio messages,
BGM broadcasts, microphone consoles, I/O extensions and cabling infrastructure.
1. General information
4EVAC Controller is the head unit of the 19” rack mounted Impact Voice Evacuation System. The Controller
covers complete EN54-16 certified functionality, as well as a variety of features essential to Public Address
applications.
4EVAC Controller incorporates 16 monitored contact inputs; 8 GPO, 4 relay outputs, 2 analogue audio
inputs and 2 outputs. In addition, local network interfaces for max. 16 local peripheral devices (e.g. mic
consoles) and 2 global network ports for interconnecting multiple systems in a redundant ring topology
are included.
The Controller is designed to work with 4EVAC DCA2.500 power amplifiers over a 4EVAC proprietary AMP
LINK protocol. The Controller can also be easily integrated with any third-party PA/VA power amplifier.

4. Back panel
Analog audio inputs
In the left section the Controller provides 2 independent analogue audio inputs dedicated for BGM
broadcast.
2 x mono, balanced, line level (0dbU / 0.775Vrms), 15kΩ input impedance.
Connect your auxiliary audio source for background music or low priority external paging microphone here.
AMP LINK
The AMP LINK (RED vertical cat5 cable) is the secured bus connecting the Impact
Controller to up to 16 x DCA2.500 amplifiers. Based on RS485, this internal system
bus provides:
- 2 balanced audio channels across the entire AMP LINK chain, monitored;
- Control and diagnostics data interface.
In order to work properly, the AMP LINK must be set up in the configuration settings
(“Amplifier” tab).
Amplifiers connected to the AMP-LINK are addressed and initiated by the Controller
at each system reboot.
NOTE: Reboot the system (Controller front panel RESET) after each modification
applied to any amplifier on the AMP-LINK, including:
-
replacing / adding / removing a DCA2.500 amplifier (along with new configuration settings);
-
changing DIP-switch settings on DCA2.500 back panel;
-

The AMP-LINK is monitored but not redundant. Therefore, in order to maintain EN54 – IP30 compliance,
the AMP-LINK cable must not be exposed to external field influences and remain fully protected and closed
entirely inside the cabinet of the Impact system.
Amplifiers connected to the AMP-LINK are addressed (numbered) in the same order as they are physically
connected to the controller via an AMP-LINK cable. In the configuration and diagnostic software
information “Amplifier 1” is the first unit on the bus (i.e. the closest and connected directly to the controller),
“Amplifier 2” is the second unit in the chain, etc.
AMP-LINK audio + data bus
Local network
The L-Net daisy-chain topology is dedicated to peripheral devices of the Controller, such as zone-expander
modules or remote microphone stations. The L-Net is used to expand functionality of the Impact system
to remote locations via a powered data bus. Every L-Net port is powered with 24V DC and power over L-
Net is always enabled.
The L-Net capacity of a single Compact 500 unit is limited to the following figures:
Maximum 8 devices per port,
Maximum 16 devices per Controller.

L-Net daisy chain topology
The L-Net port delivers power to remote devices. The maximum power capacity of each L-Net port is
500mA (protected with a, slow type, automatic fuse). L-Net devices of different types have different average
power consumption, which may vary from 30mA up to 180mA. This implies limitations in terms of the
maximum number of devices powered over the L-Net.
NOTE: Consider power consumption of L-Net powered devices!
In the table below, you can see an example of power consumption over the L-Net. This example showcases
the usage of a single type of L-Net device (4E-FMTC microphone console with 180mA current consumption
@24V), where the units are distributed equally over the L-Net cable.

Note: Power injectors are available and can be found on our pricelist from May 2020.
Global network
G-Net is a redundant network ring where multiple Controllers may be connected into one system. It is used
to reliably synchronize data between all connected devices and for multi-channel live audio transmission
with very low latency. G-Net works as a redundant double ring between Controllers, which keeps the global
system intact in case of single link failure.
To create a redundant G-Net ring between multiple Controllers, connect both G-Net ports between every
unit in the network, so that you create a closed ring.
Power over G-Net (active by default) is dedicated to supply devices connected to the G-net port, such as
fiber transceivers (FSC).

Ethernet (option)
Interface to built-in dual port Ethernet switch (future expansion port for IP connectivity).
Device ID
The Controller is equipped with a rotary switch that determines the Device ID (or device address) in the
network. Make sure that the Device ID set on the rotary switch complies with the ID defined in the
configuration settings for this device.
Wrong ID setting will trigger a system fault because of a configuration error.
Micro SD card
The Controller is supplied with a pre-installed micro SD memory card. The memory card contains a
complete system configuration file, including audio messages.
The configuration file is prepared in the 4EVAC Manager – a Windows GUI application. More information
about creating configuration settings can be found in the 4EVAC Manager User Manual.
The memory card is under constant surveillance, as well as its contents. When the memory card is removed,
damaged or its contents are corrupted, the Controller will report a system fault. During a system fault,
caused by a memory error, it enters a safe state where the system stops all functions and requires a reboot.
This state can be reset only by a manual device reset.
CAL button
Firmware version 5.2 and up:
This button is not in use (AMP LINK is set up during system reboot, based on
configuration settings)
Firmware version below 5.2:
Press this button in order to calibrate the AMP LINK bus. Once calibrated, the
DCA2.500 amplifiers on the AMP LINK will communicate with the controller, exchanging information about
the power supply and amplifier status.
RESET button
Press to trigger a hard reset of the Controller (different from the RESET button on the front panel – soft
reset). This button will trigger a hardware reset of the local Controller only.
GPO
8 x general purpose output (open collector) with common ground.
GPOs are programmable in the configuration settings. The GPO can be linked to any system events to
follow system events and various zone states.
NOTE: Each output can accept max. 110mA and max. 24V open circuit voltage.

Relay outputs
The Controller features 4 potential-free relay outputs to external devices. Each output has individual 3 pins:
normally open,
normally closed,
common.
4.11.1. EVAC
Activated (closed) during EVAC mode, where at least one zone of the voice evacuation system is
transmitting an automatic EVAC message or LIVE EVAC signal from a fireman microphone.
4.11.2. FAULT
Activated (closed) while the fault status is reported by the voice evacuation system. Also activated when
the Controller is not powered.
4.11.3. RESET
Activated (closed) immediately after a manual reboot of the system is triggered on the front panel. The
active pulse length of the reset signal is configurable from 0 (disabled) to 5000ms in the configuration
settings.
4.11.4. USR DEF
This relay output is not in use.
EVAC inputs
There are 16 monitored inputs dedicated to triggering signals for evacuation, silence and reset instructions
from an external fire detection system, as well as any other events, including commercial activities.
Each of these inputs has 1 triggering pin, with a common ground level for all inputs. EVAC inputs have built-
in DC monitoring which requires two resistors of 4.7kΩ + 10kΩ in order to detect input active/inactive states
as well as short and open faults. The EOL resistors must be located directly at the triggering output inside
of the external device (i.e. fire detection system) to provide reliable surveillance of the entire link.
EVAC inputs must receive an activation signal of at least 100ms in order to trigger events. Pulses shorter
than 100ms will be ignored.
