4E-SW6 is a DIN-rail mounted 100V audio matrix with 2 inputs and 6 outputs, dedicated to both 4EVAC
Compact and Impact systems. The 4E-SW6 has two 100V audio inputs (CHA, CHB) which connect directly
to amplifier outputs. The 4E-SW6 expands the number of independent loudspeaker lines with individual
surveillance and short-circuit isolation. Each loudspeaker line can handle up to a 500 W load and can be
assigned as a separate individual zone. One input can accept a maximum of 1000 W of power, which is also
the limit for the total load of all 6 output lines together.
4E-SW6 is responsible for:
-
zone routing: switching outputs between amplifier input A / input B / internal surveillance bus;
-
loudspeaker line monitoring: real-time impedance measurement at 20kHz with EOL.
-
backup amplifier: amplifier surveillance and automatic switch over to backup amplifier.
4E-SW6 is controlled by the Impact Controller via L-Net, receiving real-time routing information for each
output line in order to connect to channel A, channel B or internal surveillance bus C.
Multiple 4E-SW6 modules can be fed in parallel by the same amplifier, splitting its power to more zone
outputs.
Expander – network port extender for L-Net devices
4EVAC 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).
