The invisible GEALAN-SENSE® window opening sensor consists of two parts: a status sensor and a magnet.
The status sensor is mounted in a concealed position on the window casement’s fitting and records the position of the window handle. The magnet is mounted in the window frame’s rebate and detects the position of the window.
This combination triggers a loud alarm via the integrated alarm transmitter as soon as the window is pried open during an attempted break-in.
