Example 3:
consider the contribution of 2 other sensors.
To give a sensor twice the weight of each of the
other two, set the parameters as:
Weight illuminance
2
Weight remote illuminance 1
1
Weight remote illuminance 2
1
The total weight is 4 (2+1+1) the
internal sensor weighs 2/4 of the
total (50%), the remote sensors 1
and 2 weigh 1/4 each (25%)
12.
Sound sensor
The MULTI and SPACE models are equipped with a
sensor capable of detecting sounds and measuring
their intensity. Using this sensor it is possible to
send the value in decibels relative to the sound level
of the room via bus: this measurement, together
with those of brightness, relative humidity and
temperature, is used for the control and certification
of buildings (see Leed®, Breeam certifications ® and
Well®).
The sound sensor is also used in environments
where there are parts not visible to the infrared
sensor, such as bathrooms.
Using ETS parameters and communication objects
it is possible to configure actions related to the
detection of sounds or, after the device has
detected movement through the passive infrared
sensor, it is possible to prolong the switching on of
the lights also on the basis of the detected sounds.
At the end of the follow-up time, after the light has
been automatically turned off, the sound sensor can
listen for a set period so that the light can be
reactivated by the sounds even after turned off. The
sensor can be configured with different sensitivity
values (from very high to very low); it is important to
select the appropriate value based on the intended
use of this sensor.
The sound sensor detects sounds or noises
whose intensity differs from the average
value of the environment in which it is located; in
other words, the sensor uses an adaptation
algorithm to avoid false detections if the
background noise changes slowly.
The sound sensor can be enabled or
disabled from the bus via a 1-bit
communication object, it is therefore possible to
keep it enabled at the times when you want to
obtain the maximum performance of the device in
terms of sensitivity and disable it when it is not
necessary (for example in work environments may
be active during working hours and not active in
other hours).
KNX PARAMETER
SETTINGS

Defines whether the sound detection function is enabled
or disabled at the end of the download, the function can
also be enabled or disabled from the bus.

As in the previous parameter:
if the day-night switching
object is enabled, it will be
possible
to diversify
