Call Function from the Main Control (Gong)
Loudspeaker announcements can be made using the call function on the main control. This sounds a gong/signal
on the selected intercom system on the customer side, to alert customers/visitors to the announcement to follow.
To call an extension on the customer side, button - of the extension has to be kept pressed. During the
complete announcement, this button has to be kept pressed. After approx. 1 second, the signal can be heard on
the intercom on the customer's side. On the control panel, the gong is displayed by a flashing symbol for the
outside loudspeaker . After the gong, the - symbol stays illuminated and the operator can start talking.
Whilst speaking, the button for the customer side extension has to be kept pressed. When the button is released,
the system switches to the previous intercom extension combination. The call function described can also be
carried out with the same customer side extension that had already been selected.

Mute

By activating the mute mode, the volume on the customer side extension is switched to mute. The microphone on
the customer side, however, remains active. The mute mode is useful when e.g. an internal consultation with a
colleague is needed, which the visitor is not supposed to hear.
To activate the mute mode, the multi-function button on the main control has to be kept pressed until the
illuminated ring on the microphone starts flashing. While the mute mode is active, the multi-function button is
illuminated. Mute mode can be ended using any button (except plus/minus buttons).
ATTENTION: Mute mode also ends by pressing the button of a passive inside extension. After the mute mode
ends, the loudspeaker on the outside will become active again and the visitor can again hear what is being said on
the inside.

Pick-Up / Taking Over a Conversation from a Passive Inside Extension

If one or more passive inside extensions are connected to the central control, then those inside extensions can
take over a conversation by quickly pressing the PickUp button (e.g. conversation requested by 'gong' from the
outside). By pressing the button again at the passive main control, the system automatically switches back to the
previous combination.
Example: The Pick-Up function is recommended if there are two employees working in a porter's lodge, the
employee at the main control is working but is telephoning at the moment. The second employee can simply take
over the conversation by using the Pick-Up function.

Controlling the Door Opener

To operate a connected door opener, first select the door outside extension or that is to be opened. Then
press the key button . The door opener will then be activated for approximately 2 seconds.
