The Leakage sensor Leak KNX 2.0 includes an evaluation unit and a probe. If there is water between the electrodes of the probe, the evaluation unit produces an acoustic alarm. Additionally, the alarm signal is sent to the KNX bus.
Even if no probe is connected or the cable is defective, the alarm can be sounded and signalled on the bus.
Functions
- Detection of water on the probe
- Acoustic alarm signal by the evaluation unit during a water alarm (sustained beeping tone). Short beeping during the follow-up time (1 minute after the end of the alarm).
- Alarm signal sent to the KNX bus with a text message
- Detection whether probe is connected and the probe cable is functional
- Acoustic alarm signal on the evaluation unit when the probe is not connected or when the probe cable is broken (long beeps)
- 4 AND and 4 OR logic gates with each 4 inputs. Every switching incident as well as 16 logic inputs in the form of communication objects, may be used as inputs for the logic gates. The output of each gate may optionally be configured as 1 bit or 2 x 8 bits
- Configuration is made using the KNX software ETS 5.
