Description
The Leakage sensor Leak 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 output of the evaluation unit switches on. The output can be
used to transmit the alarm signal to other systems (e.g. klaxons, light indicators, stop
valves, building control system, alarm system). The changeover contact design of the
output makes it possible to detect wire breakage in the alarm line by suitable systems.
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).
•
Output for alarm reporting (potential-free changeover contact)
