(1)
Compare D
open
and D
short
and pick the one of smaller absolute value. This absolute
value is your minimum deviation D
min
.
(2)
Calculate optimum tolerance as:
T
opt
[%] = ½ * (D
min
+ 5%)
E.
Set tolerance
a)
In EOL monitoring settings in 4EVAC Manager (tab Devices) set tolerance of the tested
line to T
opt
;
b)
Upload new configuration;
c)
Open “Live monitoring” again.
3)
Perform final check
A.
Set the line in the final configuration
a)
Connect and secure EOL module at the end of the line;
b)
Calibrate impedance measurement (press the button on SW6);
c)
Wait for the measurement to stabilize;
d)
In “Live monitoring” window click “Get Reference Impedance”;
e)
Compare “Reference Impedance” with “Impedance”;
B.
Short test:
a)
Create short-circuit at the end of the line
b)
Observe the “Deviation” value
c)
Wait for line fault detection
C.
Open test:
a)
Disconnect EOL module at the end of the line
b)
Observe the “Deviation” value
c)
Wait for line fault detection

Operation of SW6 with Compact:
If inputs of 4E-SW6 are attached to power amplifier of Compact 500 in system settings (see 4EVAC
manager GUI manual), and output lines of 4E-SW6 are attached to zones, then the 4E-SW6 can
route each of the outputs to any input, depending on routing command from main controller.
4E-SW6 can transmit to its output lines maximum 2 different audio signals (channel A, channel B)
and silence (internal surveillance bus C). If user attempts to transmit more than 2 signals (e.g. bgm
to zone 1, paging to zone 2, pre-recorded message to zone 3), then system will automatically assign
available channels to the top priority audio signals and route the output lines to the appropriate
positions (CH A / CH B). Lower priority signals will be discarded.
