1. What is the Controller-Expander?
4EVAC Controller-Expander is an optional component of the 19” rack mounted Impact Voice Evacuation
System. The Controller-Expander is identical to the Impact Controller with significant hardware and
functional limitations.
The Controller Expander cannot not be used alone as a standalone VACIE (Voice alarm control and
indicating equipment), as it does not feature EN54-16 mandatory inputs / outputs. The Expander may be
used in the system only as an additional interface, connected to the main network of 4EVAC VACIE main
units.
Functionally, the 4EVAC Controller-Expander works as a network hub for additional L-Net devices, such as
microphone stations.
In terms of interfacing, the Controller-Expander only features a DC power input and network ports (Global
Network and Local Network).
The Controller-Expander includes:
- Front panel indicators
- DC power input
- Network ports:
o 2 x Global Network port – to interconnect multiple Controllers in a redundant ring
topology
o 3 x Local Network port - for max. 16 local peripheral devices (e.g. mic consoles)
- microSD card with configuration settings
- 2 x hexadecimal rotary encoder (device ID setting)
- USB port for firmware upgrades
- RESET button – hard CPU reset

2. Front panel
Indicators (functions identically to the Impact Controller, except power supply fault):
POWER
Indicates if the Controller is being powered and if the system is booted properly.
OFF
Not powered
GREEN continuous
This device is powered and operational.
GREEN blinking
This device is booting after power up / reset.
EVAC
Indicates that the system is in Voice Alarm, where at least one zone in the system is occupied by an
emergency audio signal, i.e. a pre-recorded EVAC MESSAGE or LIVE EVAC, when a fireman mic is being
used.
OFF
EVAC status is inactive (quiescent mode)
RED continuous
EVAC status is active
GENERAL FAULT
Indicates that the system is in FAULT condition (general fault indicator), where at least one device in the
system is reporting a fault.
OFF
System is healthy
YELLOW continuous
Local fault is detected (this Controller-Expander)
YELLOW blinking
Local device (this Controller-Expander) is healthy and at least one remote
device is reporting fault state
POWER SUPPLY FAULT
Not used.
The Controller-Expander (in comparison to the Impact Controller) has no management interface to power
supply equipment, so there are no local power supply faults to be reported.

SYSTEM FAULT
Indicates a system fault of the Controller-Expander, where:
- A CPU or program execution is stopped or malfunctioning,
- Storage memory containing config settings and audio files (SD card) is corrupted.
Where the system fault is caused by a CPU or memory fault, the device remains in its “safe state” where
critical functions (including audio transmission, reaction on control inputs, etc.) are stopped until the fault
is resolved.
OFF
Firmware and settings OK
YELLOW continuous
CPU / program fault
YELLOW blinking
o SD card fault
o Config file not compatible
o Wrong ID setting
NETWORK FAULT
Indicates when any device or link in the network is missing.
OFF
Network OK
YELLOW continuous
At least one device from the Local Network of this Controller-Expander is
missing.
YELLOW blinking slow
Global ring is broken (any place in the ring)

Local network
The L-Net daisy-chain topology is dedicated to peripheral devices of Controller, such as remote
microphone stations. The L-Net is used to expand functionality of the Impact system to remote locations.
Multiple microphone stations may be used in the same L-Net, with the following limitations:
A maximum of 8 stations per L-Net port
A maximum of 16 stations per single 4EVAC main unit (total sum of all 3 L-net ports)
A microphone station may be also daisy-chained together with other L-Net devices
NOTE: Controller expander does not support 4E-SW6.
Global network
G-Net is a redundant network ring where multiple Controllers and Expanders 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.
NOTE: The Controller expander must be connected with the main system unit (Impact Controller / Compact
500) via a redundant G-Net ring..
Device ID
The Controller-Expander is equipped with 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
configuration settings for this device.
The wrong ID setting will trigger a system fault because of a configuration error.

Micro SD card
The Controller-Expander is supplied with a pre-installed micro SD memory card. The memory card contains
the complete system configuration file.
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 the system fault
caused by a memory error, the Controller 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.
RESET button
Press it to trigger a hard reset of the Expander (different from RESET button on front panel – soft reset)
4. Configuration settings
The Controller-Expander remains a G-Net device and as such can be supplemented with max. 16 L-Net
devices, which will be local slaves of this Controller-Expander.
The Controller-Expander (in comparison to Impact Controller) requires no local configuration settings,
except an ID / name / priority.
In the 4EVAC Manager configuration software, it is not possible to add a Controller-Expander without
having at least one G-Net device in the configuration first, i.e.:
-
Impact Controller
-
Compact 500.
5. Network cabling
The 4EVAC network features a full duplex RS-422 data link and 24V DC power to remote devices.
If you’re building a distributed system using the 4EVAC network, you should make physical links between
devices using the right cables. Cabling should meet the following requirements:
1. Crossover twisted-pair cable (compatible with Ethernet crossover)

2. CAT5e or higher for maximum distance of 250m.
3. Non-CAT / lower than CAT5e: 250m not guaranteed.
4. Shield required (at least FTP)
NOTE:
If you use a straight cable, the device will power up but the Tx/Rx data terminals will not be properly
connected. This will result in a communication fault between the L-Net device and main controller unit. The
L-Net device will not be able to initialize, thus will remain in boot-sequence, not operational.
Caution! Use only crossover cables and keep the correct pinout! Connecting power pins to data pins will
damage the network port.
