Relay operating modes
Relays can have various functions on the PBX.
You can configure the following operation modes:
Speaking
The relay is assigned to a door terminal or an announcement output.
The PBX switches on the relay as soon as an audio connection has been established between the PBX and the assigned device (e.g. an a/b-Audiobox).
The PBX switches the relay off as soon as the audio connection is terminated.
Possible use:
• Switching an LED of the door terminal
• Switching the loudspeaker area of the loudspeaker system for the announcement output
Door opener
The relay is assigned to a door terminal.
The PBX switches on the relay as soon as an internal subscriber triggers door opening for the assigned door terminal.
Alternatively, switching can be triggered manually by phone.
The PBX switches off the relay after the defined switching duration.
Possible use:

Light
The relay is assigned to a door terminal.
The PBX switches on the relay as soon as an internal subscriber triggers light switching for the assigned door terminal.

Depending on configuration
The relay is assigned to one or more configuration/s (day, night, etc.).
The PBX switches on the relay as soon as an assigned configuration is switched on.
The PBX switches off the relay as soon as a configuration to which it is not assigned is switched on.
Alternatively, switching on/off can be triggered manually by phone.
