•
Nominal Z mute
: Same as the previous one but calibrated by the measurement
system in Mute or low power. (Both values may differ slightly due to the use of two
independent measurement systems)
•
Calibrate:
Start a new calibration of the line.
NOTE
: It should only be done when
the user is sure that the line is OK. The equipment has a maximum limit of
measurement (600 Ohms), when the impedance exceeds that limit it will dial
9999. A line terminator should be used in those cases.
•
Lower Tol% y Upper Tol%
: They are the limits of variation allowed in percentage
with respect to the impedance calibrated to indicate open or short circuit.
•
Parent Zone:
Zone number which this line belongs to.
•
Parent Label
: Label of the zone.

b) A/B mode
This option enables the A/B wiring mode. In this mode system will use two speaker
lines for each zone, in case of a line failure(A) the zone will be still working thanks to the
other speaker line(B). But maximum number of zones will be reduced to 3 for each ONE
device. This mode is enabled for all zone outputs.
c) Zones Numer
Indicates the number of zones that the system has, disabling the outputs that are not
being used.
3.3.5 Import and edit messages. Messages
To edit evacuation and alert messages, the system has these options.

Storage
:
◦
View Playlists:
It allows the user to consult how the playlists have been and
the order in which they will be played. It also allows you to delete the
messages one by one.
◦
Import MSG:
To import messages from the USB memory. A DATAxx folder is
chosen from 01 to 99. The files must be in the predefined location, they must
also have the correct format:
▪
File .wav PCM monochannel 16 bits, 24 o 48kHz
▪
..\DATAxx\EVAC\ for evacuation.
▪
..\DATAxx\ALERT\ for alert.
▪
Messages with the same name will be replaced, messages with different
names will be added.
▪
USB Memory stick file system should be
FAT32
. File names should have a
maximum of
8
characters without spaces or symbols and .WAV extension.
