The diagrams show some auxiliary circuits that enable the repetition of the sound signal
in the "temporary" mode and in the "continuous" or "intermittent" mode, necessary when
the calls must have an "emergency" or "alarm" characteristic (e.g. from bathrooms, hospital
bedrooms, technological rooms, ...).
When there are ongoing calls, the auxiliary contact of the display unit (terminals 1-5), closed
as long as the call pushbutton remains pressed, activates bell S in the "temporary" mode.
Instead, in the "continuous" mode, bell S is activated by contact Rt1 of the auxiliary mo-
nostable relay Rt. In the "intermittent" mode, sound signal S is activated by contact Ra1 of
the auxiliary relay Ra, which is activated by intermittence It. In these two last two cases,
the operator can silence the bell by pressing pushbutton Pt. The bell will be activated again
by the next call.
