DEVICE DESCRIPTIONS

System ON / OFF

The ON key switches a PROANNOUNCE system ON or OFF. Mostly, it is not intended that any paging station be provided with the possibility to do so. Thus, this function can be programmed via PC-configuration.

When the system is in stand-by mode, the ON LED is off. Pressing the ON key turns the PROANNOUNCE system’s power on which can take up to 10 seconds, while the ON LED is blinking. Once the system is ready for operation, the ON LED lights continuously (which also applies for all paging stations of the entire installation).

To switch the system OFF, you have to press the ON key for approximately 1 second. This is to prevent inadvertently turning off the system.

Pressing an ALARM key or igniting an alarm sequence at external terminals automatically switches the PROANNOUNCE system’s power on and boots the system.

Program Assignment

Activating this feature allows the assignment of programs to individual areas and groups of the entire installation during the PC-configuration procedure.

First, by pressing the PROGRAM key, the paging station has to be set to program-assign mode. Pressing a single or several selection keys assigns the outputted program (background music) to the selected areas and groups. The corresponding LED’s are lit. Program transmission has always the lowest priority (1). The signal level is determined during system configuration. The assignment stays memorized until the selection keys are pressed again. Pressing the CANCEL key erases the entire assignment-pattern.

Subsequently pressing the PROGRAM key or any other function key cancels program-assign mode. It is also automatically canceled after approximately 15 seconds.

In single-program configuration the music reproduction into all areas of the installation is attenuated for the time of an announcement. In double-program configuration parallel transmission of a background music program into rooms that are not part of an actual announcement selection is possible as well. If every line incorporates its own LF-output and separate power amplifiers, mixing announcements and background programs is possible in any way.

Special Functions

Generally, assigning a function to each selection key is possible. This allows utilizing a paging station to control the lighting, door openers, blinds, etc.; even controlling volume settings is possible through the use of the UP / DOWN keys.

When shipped, there are no special functions assigned.
