Note: To connect the door entry system, look up in the technical datasheet that comes with
the audio unit.
When the monitor auxiliary button is pressed, the circuit of the control signal (15Vdc) is closed
through terminal 25 (+). Additionally, when a call is received and when the auxiliary button
of the telephone is pressed, the signal generated in terminals SC1, 18 of the audio unit is
used as a control signal. Both control signals allow the electric lock of the second door to be
supplied with power for a pre-established period of time (see timing in adjusting instructions).
