44.4System settings

A number of general, system wide parameters can be set using the System wide settings page (see figure 44.11).

figure 44.11: System settings

•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.

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.

•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
