DEVICE DESCRIPTIONS

5.2.6 Operation

This chapter explains all functions that are used during general operation.

Selective Call

The user can launch calls or announcements into freely selectable areas or groups.

Pressing a single or several selection keys defines areas or groups where a call is launched into – corresponding LED’s will light. By pressing the key of an already pre-selected line once again deactivates that line and the corresponding LED goes out.

After making a selection, pressing the TALK-button ignites the call. Prior hereto, the BUSY LED allows checking whether all lines and the paging station input are actually free. If single lines or the terminal input are busy with lower priority transmissions, the BUSY LED will blink slowly. Whilst making an announcement is possible, this will interrupt any other transmitted event. If single lines or the terminal input are busy with higher priority signals, the BUSY LED will vastly blink and the calling attempt is ignored (also refer to the description of indications).

The BUSY LED lights during the transmission of an announcement. The TALK button has to be pressed during the whole message. Until the user makes any changes, the defined selection stays memorized, even after releasing the TALK button. Pressing the CANCEL key de-selects the entire selection.

Additionally and in case of a pre-gong signal has previously been programmed, the GONG LED will light during the transmission of the pre-gong signal.

Collective Call

The announcement is launched into all areas of the entire installation.

The procedure is similar to making a selective call. First, all areas of the installation are selected by pressing the ALL key. Pressing the TALK button activates the collective call. During the transmission of a call, all area and/or group LED’s as well as the ALL LED will light (also refer to the paragraph “indications”). The TALK button has to be pressed down until the end of the announcement. BUSY LED indication and the behavior of the pre-gong signal are equivalent to the selective call.

Direct Call

Principally, assigning a direct call to any selection key (area key, group key, ALL key) is possible via PC during the configuration procedure. This allows making an announcement directly by pressing the desired selection key

–without need to press the TALK key. For direct calls the BUSY LED also signals the status of correspondent areas (free, busy with lower priority signal, busy with higher priority signal; see “indications”). When shipped, there is no factory pre-set direct call programmed.

Gong (Chime) Signal

By factory the Gong key is programmed as a general call

A gong signal can also be transmitted into any selectable area or group of the entire installation (if programmed).

First, the desired areas / groups have to be selected; either by use of the selection keys (selective gong) or with the ALL key (general gong). Pressing the GONG key releases the gong signal. While the gong signal is being transmitted, the GONG LED lights continuously or blinks (also refer to indications). The gong’s priority can be set to 6 or 7. Therefore it has priority over announcements from any paging station, except for the directing terminal (priority 10).

Pressing the STOP key cancels the transmission of a gong signal.

During setup mode this key is used to go back to the normal operating mode (escape).
