You can establish a connection between the door communication system bus and the existing (ISDN) telephone system or router (e.g. Fritzbox) with similar connections or a similar exchange connection via the TC gateway.
Please note that the programming set with item no. 1291 00 is required in all cases when connecting to the router. This is necessary in order to programme special characters (that are necessary to dial into the router) into the DCS-TC gateway.
Electrical devices may only be installed by a qualified electrician. Please see the information at https://www.gira.de/service/bauherren/installationshinweis.html
The inscription labels can also be removed or swapped by customers relatively easily without having to use any special tools. To remove or swap an inscription label, follow these steps:
- Remove the call-button cover plate, using a screwdriver for example.
- Remove the inscription label.
- Affix a new inscription label, if required.
- Reattach the call-button cover plate.
The type of home station dictates whether and how the ringtone or voice function volume can be change. “Standard home station” with receiver: Only the ringtone volume can be changed. The voice volume is preset and cannot be changed. To change the ringtone volume, press the light operating button for approx. three seconds with the receiver off the hook. “Home station with hands-free function” and “Komfort home station” with receiver: Both the ringtone and voice volume can be changed. To make the changes, press the volume button.
Call force-through is not necessary with the Standard and Komfort home stations with receiver. This is because there are fundamental differences in speech transmission between the home station with hands-free function and a home station with receiver. The home station with hands-free function uses what is known as an echo suppressor. This means that, in voice mode, there are two voice ICs working together (1x in the home station with hands-free function, 1x in the door station). The voice ICs detect when speech is transmitted from the door station. The microphone pathway of the home station with hands-free function is muffled. In this case, in order to force the call from the home station through to the door station, you need to exceed the preset volume level. Normally, this is not an issue as, during a call, the person at the door has finished speaking before the person in the house answers. However, this becomes problematic if the person speaking at the door station has finished but the background noise (e.g. car noise) is so loud that the noise level does not drop sharply. As the microphone pathway is still considerably muffled in this case, the person at the home station must speak significantly more loudly for their call to go through. The force-through function helps here; it technically cancels the microphone pathway muffling and allows you to easily force the call from the home station through to the door station. This function is not required in home stations with receiver as the microphone circuit is not muffled in this way. For the version with receiver, it is fundamentally easier to force through a call from the home station to the door station, even if there are loud background noises.
The surface-mounted home station with hands-free function has five ringtone melodies that can be individually assigned to the floor-call button, the call buttons on the door station or the internal call buttons of other home stations. In a household with multiple people for example, this allows you to assign each person their own door station call button (e.g. parents, children) with individual ringtone melody.
To set a ringtone melody, follow these steps:
1) Sound the ringtone for which you want to change the melody. To do this, press the relevant call button that was previously taught in.
2) To change the melody of the most recently triggered ringtone, press the button for ringtone deactivation on the home station and hold it down.
3) Within three seconds of this, press the light button and hold both buttons down until you hear the new ringtone melody.
4) To select the next ringtone melody, repeat steps 2 and 3. Each time you press the buttons (ringtone deactivation and light button), a new ringtone melody is set. Once you reach the last ringtone melody, the first melody will be set the next time you press the buttons. Note: When deleting a call button allocation for the home station, the corresponding ringtone melody is reset to the factory setting.
