FAILURE DETECTION
ϱ͘ϭ
SPEAKERS LINE
The system will indicate a failure in the speaker's line in case a short circuit or an open circuit has
been detected or the impedance of the line has varied by at least 14%.
If this error occurs, check the specified line in the system error log. To do this, disconnect the speaker's
line and measure the impedance between the cable terminals with an impedance measuring equipment.
Check that the values correspond to those expected according to the number and power of existing
speakers in the line. Check that there is no short circuit between any terminal and earth. If any of these
measures is beyond the expected values, leave the line disconnected and check the status of the line and
speakers to detect the problem.
ϱ͘Ϯ
TRANSMISSION LINE WITH CIE
The system will indicate a failure with the CIE transmission when it detects that the transmission path
is shorted or disconnected.
If this error occurs, check the connection between the system and the CIE has been carried out in
accordance with section 12.To debug the failure, disconnect the two ends of the cable connected
between the CIE and equipment and measure between the cable terminals with a multimeter on the
scale kΩ. If the measure result 0, the line is shorted. If the result is 1, it means that is open. If the result
is 20kΩ then the line is correct. In either of the first two cases, replace or repair the transmission line.
ϱ͘ϯ
PROTECTION DEVICES
The system will indicate a failure of protection when any of the internal protective devices of the
equipment are active.
If this failure occurs, the amplification channel/s that have the power protection indicator, have
overheated. In that case, make sure the equipment has an adequate ventilation, make sure the air inlets
and outlets are not blocked. The equipment has been protected to prevent serious damage. It is possible
that if you turn off your equipment, it run again after several minutes. Avoid this mode because it can
cause severe damage. To avoid damaging the equipment, turn off the voice alarm zones where the failed
occurred and notify it to the support service.
ϱ͘ϰ
POWER SUPPLY
The system will indicate a power failure in any of these situations:
Main power supply: There was a failure in the main power supply. If this error has occurred, check
that the power supply network reaches the equipment. If so, disconnect the equipment from mains and
check the fuse at the input socket on the rear. If the fuse is broken, replace it. If you restart the fuse and
it breaks again, call your support service.
Redundant power supply: There was a failure in the redundant power supply. Check the correct
operation of it, following the manufacturer's instructions. If it works properly, check that the transmission
lines between the equipment and the redundant power supply are correct as shown on section 4.1.

If in addition to indicate a power supply failure, failure is indicated in one of the amp channels, it can be
that one of them has suffered a breakdown. To avoid damaging the equipment, turn off the voice alarm
zones where the failure occurred, and seek support service.
ϱ͘ϱ
LINK
The system will indicate a link failure when there is a problem in the way of communication between
distributed devices. If this failure occurs, you can see which are the equipment connected to the
controller, in the window system, of the advanced options menu (3.5.3). Restart the equipment that is
down. If the problem persists, ensure that the connection between the two is correct (4.3).
ϱ͘ϲ
SYSTEM
The system will indicate a system failure when a problem has occurred in the execution of the
software, or memory. If after several reboots, the problem persists, connect the equipment to the
configuration application and restore the version of firmware. Do not forget to restore the site data
backup after restore. After this operation, the equipment should function normally, if not, contact your
support service.
ϲ
MAINTENANCE INSTRUCTIONS
The equipment/system requires a reduced periodical maintenance.
The periodicity of the maintenance must be adjusted in function of the condition of installation of
the equipment/device. It is advisable that the maximum period for maintenance of the equipment
should be of one year.
Operations:
•
Clean the entrance and exit ports of air with a vacuum cleaner.
•
Check the connections of the equipment and the ground connection.
Warnings:
•
Use only a soft, lint-free cloth.
•
Disconnect the equipment from any external power source.
•
Disconnect all external devices.
•
Keep away from liquids.
•
Do not use aerosol sprays, solvents, or abrasives.
•
Do not spray cleaner directly on the device.
