Alarm system for securing boats moored on jetty

摘要

The alarm system has an electrical or optical conductor in the mooring line (2) which can be connected to a power supply and to an alarm. The mooring line is fed once or a number of times through a portable, stable closed housing (4) with at least two suitable openings (5) for the mooring line, at least one power supply (9) and a contact or motion sensor (10) for the line. There is a contact or motion sensor (11) directed and operating out of the housing, an audible and/or visual and/or radio alarm (6,7,8) and a security on/off switch (3) with key, numeric or alphabetic code also forming a transponder. The alarms are triggered by line movement inside the housing, pulling the line out of the housing or removing the housing from the jetty (1).
