Magnetic contact detectors belong to the essential devices of perimeter
protection. They are used to protect doors, windows, etc., by triggering alarm
when they are open. The S-2 detector is designed for flush-mounting, i.e. its
elements are to be pressed into suitably prepared holes in wooden or plastic
door frame, window frame, etc. S-2 consists of two watertight parts: the reed
switch (magnetic) sensor and the magnet, whose faces should contact each other.
Moving one part away from the other breaks the sensor circuit, which is
indicated as a violation. Additionally, the detector is provided with
a tamper loop.
S-2 is designed to work with any alarm control panel having NC inputs as
well as to be used in automation system as a control element. It meets the
requirements of EN 50131-1 and EN 50131-2-6 standards
for Grade 2.
The S-2 detector is available in two color versions: white (S-2) and brown (S-2 BR).
