44.4 System settings
A number of general, system wide parameters can be set
using the System wide settings page (see figure 44.11).
• Redundant ring network - Specifies whether
the Praesideo network forms a redundant ring (Yes)
or not (No). If set to yes, cable breaks are reported.
• Message FLASH card available - Specifies
whether the network controller contains a compact
flash card (Yes) or not (No). If set to yes, the
availability of the flash card is monitored.
• Key timeout - After this time, the selection that
was made using a (remote) call station is
automatically cancelled if the selection has not been
executed. The key timeout also determines the timeout
for locking the call stations when the call stations are
used with a numeric pad and the access timeout has
been set (see section 43.4.6).
• Allow access by non-configured TCP/IP
devices - Specifies whether TCP/IP devices that are
not part of the system definition can access the
system (Yes) or not (No). If set to No, all TCP/IP
devices that access the system must be added to the
system definition (see section 42.9).
• Activate new tone set - Imports a new tone set
into the configuration. If the system has been
upgraded from a previous software version, select
Yes. New software versions include tones that are not
available in other versions or tones that have
improved tone characteristics. New installations will
automatically use the new tone set.
• Emergency Mode: disable calls below
priority level - Calls with a priority lower than the
specified priority are disabled if the system is in the
emergency mode. The system is automatically put in
the emergency mode when an emergency call is
started.
• Back-up Power mode:
• Disable calls below priority level - BGM
and calls with a priority lower than the specified pri-
ority are disabled if the system is in the back-up
power mode. Use the Back-up power mode action to
put the complete system in the back-up power mode.
See section 47.3.25. Individual power amplifiers and
basic amplifiers go to back-up power mode if the
mains power of that unit disappears. Then BGM and
calls with a priority lower than the specified priority
are only routed to amplifiers (zones) that are not in
back-up power mode.
• Switch amplifiers to standby - Power save
mode. During use of the back-up power supply, the
amplifiers are set to standby if Yes is selected here.
When a call that has a higher priority level than that
set in the Disable calls below priority level
field, the required amplifiers are made active, and
the call is broadcast. The Power-save mode extends
the period of time that the battery back-up power
supply is able to provide power to the Basic and
power amplifiers. Power save mode is only available
during the time that the back-up power supply is in
use.
• Release call station fault indicator after - The
yellow power/fault LED (see table 15.1) is released
after a fault has been acknowledged or after a fault
has been reset. It is not necessary to resolve a fault
before acknowledging it.
• Reactivate silenced fault alarm buzzer - A
timeout period can be configured after which a fault

Note
When Power-save mode is set, a spare amplifier
that is not in use also goes to Power-save
mode. A main or spare amplifier that is in
Power-save mode is not supervised and will not
report any faults.
Any faults that do occur during Power-save
mode are secondary faults, the mains failure is
the primary fault. In most cases, it is allowed that
secondary faults are not reported.
