Motion detector attachment 2.20 m comfort for KNX color aluminum System 55 - Adjustment of the sensitivity via an adjuster on the device or with IR remote control PIR KNX (accessory). - Evaluation of the measured brightness using up to three independent brightness limit values. - Display of motion detection (permanent or only in the walking test). - Up to 5 function blocks that can be freely configured for the application 'guardian', 'guardian with switch-off brightness' or 'detector'. - Two output communication objects are available for each function block, via which the switching and control commands are sent to the KNX bus. - Configurable functions: switching, staircase function, dimming value transmitter, scene extension, temperature value transmitter, brightness value transmitter, operating mode switching, switching with forced position. - Function block switching for bus-controlled switching between two function block groups. - Switching the operating mode (OFF / AUTO / ON) of the first function block during operation by local operation or via communication object by local operation on other motion detectors for KNX via touch sensor for KNX or visualization. - Demand-oriented blocking of individual function blocks via the KNX. - Manual operation of the controlled KNX actuators and consequently deactivation of the PIR automatic is possible. - In brightness-independent operation, the function block can determine the time period after the last movement and send it to the KNX bus via a communication object. This function allows, for example, simple monitoring of people's movements in assisted living or in a retirement home. - Functionality of the motion detection can be adjusted for the 'guardian' or 'guardian with switch-off brightness' application. - The device can be used in the 'guardian' or 'guardian with switch-off brightness' applications as a single device, as a main unit or as an extension unit. - Walk test function to help with the planning and setting of the PIR detection area. - Integrated room temperature measurement. - Dismantling alarm, when the device is removed from the bus coupler a 1-bit or 1-byte telegram is triggered. - IR remote control PIR KNX (accessory) for setting functions of the first function block (twilight level, sensitivity of motion detection, motion evaluation and follow-up time). Switching the walk test function on and off.
