Magnetic detectors (K-3)

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-3 detector is designed for flush-mounting, i.e. its elements are put in place by screwing their aluminum enclosures into properly prepared holes in wooden or plastic door frame or window frame. K-3 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.

K-3 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.
