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 K-2 2E 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. K-2 2E 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 two 1.1 kOhm resistors connected with reed switch in 2EOL configuration.
They enable the control panel to detect tamper of the detector by registering
changes in resistance of the input line.
K-2 2E is designed to work with any alarm control panel provided with NC
inputs as well as to be used in automation system as a control element.
The detector K-2 2E is available in two colors: white (K-2 2E) and bronze (K-2 2E BR).
