If a window (or door) is partially, but not fully, closed, the
spring-loaded bolt ensures that the window is pushed open
far enough so that this can be reported to an intrusion
control panel by an associated magnetic contact.

Installation/Configuration Notes
Installation notes
•
When installing the magnetic contact used for tear-off
surveillance, it should be mounted as far as possible
from the hinge.
•
The distance (L) from the reed contact to the hinge
must be measured.
•
The travel (S) of the reed contact is to be determined
with an ohmmeter before installation.
•
For the calculation, it is assumed that the spring-loaded
bolts are fully compressed when the door or window is
tightly closed.
Positioning of the spring-loaded bolt
A = Distance from the spring-loaded bolt to the hinge
L = Distance from the reed contact to the hinge
H = Spring-loaded bolt stroke = 6 mm
S = Travel of the reed contact
