SOUNDS
Apart from the behaviour of the LEDs, it is possible to make
TMD-Display emit a
brief
beep
as an acoustic feedback in two situations:
When a button is pressed
: short beep indicating that the user has pressed a
button. This only applies to step controls, i.e., controls that walk through a
certain range of values and that do not send a value after every touch, but
only the final value after the last press.
When an action has been triggered
: sharper beep than the above one,
indicating that a value is being sent to the KNX bus.
Enabling and disabling the button sounds can be done in parameters or through an
object, being also possible to define in parameters whether the button sounds should
be initially enabled or not.
With independence of the aforementioned button sounds, TMD-Display One can also
emit
doorbell
(a single beep on request) and
alarm
(a sequence of brief beeps with a
higher pitch) sounds on the reception of certain values through specific objects. The
alarm sequence will only stop when the alarm object gets deactivated or when the user
touches any of the buttons (this will not trigger any action, only the alarm deactivation).
Note that doorbell requests are ignored while the alarm is active.
A general parameter is provided to make the ETS parameterisation easier in case the
doorbell and alarm functions are not required and the integrator feels comfortable with
