Coded Sensor Technology, a TSec exclusive, allows the production of
matching magnet/sensor pairs: for the first time, a passive sensor is

tamper circuit. CST contacts, even with such advanced features, are fully
passive, and can be interfaced with any existing alarm panel. CST-03 also
offer a very large operating gap, which makes them ideal on any type of
gate or large door. They are fully potted, for internal or external use.
