13 Bus Motion Detector
13.1 General notes
The L240 bus motion detector is available in four different variants. There is
a motion detector with passive infrared technology for VdS classes B and C
and a motion detector with dual modes (PIR* and MW**) for VdS classes B
and C. Each bus motion detector represents its own circuit. Thus, every
motion detector can be individually detected. A maximum of 40 bus motion
detectors can be managed by the panel. The entire number of circuits incl.
Detector Circuit Modules L240/MG2 or L840/MG4, KNX circuits and bus
motion detectors may not exceed 80 (incl. the 10 circuits for the panel).
Overview of the bus motion detectors:
Designation
Description
IR/XB
Passive infrared technology, VdS class B
IR/XC
Passive infrared technology, AM*, VdS class C
EIM/XB
Dual detector (PIR** and MW*** technology), VdS class
B
EIM/XC
Dual detector (PIR** and MW*** technology), AM*, VdS
class C
These detectors are in the validation process at the time of going to print.
*AM = Anti Mask (anti-mask monitoring); **PIR = Passive Infra Red;
***MW = Microwaves
