The Gira KNX presence detector is used for presence monitoring and motion detection indoors. It features an integrated bus coupling and three digital PIR sensors, and is equipped with a brightness sensor. The Gira KNX presence detector can serve as a freestanding device, main unit, or auxiliary unit at the user’s option, and enables fully-automatic or semi-automatic lighting control.
The delay time can be set flexibly and adapts to user behaviour if desired. Only a minimum and a maximum value needs to be specified for this purpose. Depending on the duration of the movement detected in the room, the Gira KNX presence detector will select a correspondingly short or long delay time.
