SUMMARY
The movement detector with Easy twilight switch - flush-mounted allows
you to send timed activation commands to actuator devices using the
KNX/EIB bus through which it connects to the Home Automation system,
according to the movements detected and the light measured by the two
built-in sensors.
The passive Infra Red (IR) sensor has an adjustable lens with fixed opening.
The detector is powered by the bus line and is fitted with two
potentiometers on the front, for local regulation of light sensitivity levels
and the local variation of the transmission period (+/- 50% of the value
set via the base unit), and a green indicator LED that signals movement
detection and the consequential messages sent to the bus. The sensor
can be configured using the Easy base unit (GW 90 831) to send timed
activation commands. It is possible to set the functions on the device
so that they activate only movement detection when the actuator to be
commanded is ON (conditioned detection).
This function mode allows you, for instance, to switch on lights in the
traditional manner (using a button or similar fitting) whilst guaranteeing
the automatic switch-off function once the area covered by the movement
sensors is liberated.
The device functions are inhibited for approx. 60 secs at switch-on, i.e. the
time needed to stabilise the IR detector.
The device is fitted inside a standard flush-mounted box, mounted on
Chorus supports in the space of two modules.
