Figure 10-10 Doorline M02 entrance telephone (four doorbell call destinations)
If a doorbell call is issued to a busy station, the doorbell call is not signalled until the call has been
terminated. The connection to the entrance telephone is then set up by dialling the relevant code.
The doorbell call follows internal call forwarding.
After the wiring is installed, parameters must be set for the control relay module
(REAL/STRB).

This adapter connects an a/b interface from the system to an entrance telephone and a door opener/bell
function. Control is via the system. Connection is possible to commercially available active and
passive entrance telephones.
