Description
The magnetic contact and the magnet must be mounted facing
each other in a window frame/door leaf and window
surround/door surround.
Caution:
Neither the contact nor the magnet can be installed
in ferromagnetic materials.
Special grade 3 magnetic contacts developed for installation in
ferromagnetic materials are available for this case.
The installation flange must only be mounted using screws
made of non-magnetic material.
When mounting is complete, the magnetic contact's electrical
switching function must be checked (e.g. using a continuity
tester or multimeter).
The application of mechanical force, e.g., when mounting the
device on the casing may damage the glass body of the reed
switch.
Only cyanacrylate adhesives (superglue) may be used to fix
the assembly parts. The processing instructions from the
respective manufacturer must be observed.
