Problem Solution
The Door/Window Contact was already
working and all of a sudden it doesn‘t
work anymore.
Restart your primary Z-Wave controller. If the door/
window contact still does not respond afterwards,
follow the steps below:
- Remove your Door/Window Contact from your Z-Wave
network (see 6.3 on page 8).
- Reset your Door/Window Contact to factory settings
(see 6.4 on page 8)
- Add your Door/Window Contact to your Z-Wave network
again
The Door/Window Contact was integra-
ted into the Z-Wave network and false
alarms occur from time to time.
1.) The sensor works optically with light in the infrared
range (IR). For reliable operation, the sensor must be
mounted on a straight surface so that the sensors are at
right angles to the base surface. Only in this way can the
emitted light pulses be cleanly reflected and returned to
the evaluation window of the sensor.
2.) Check if the surface opposite the sensor surface from
the Door/Window Contact is two-tone. If the seal is black
and the window frame has a light aluminum, it is possible
that the sensor is triggering a false alarm. If this is the
case, tape the surface that is detected by the sensor with
a reflective film that adheres well.
Advice: The reflector strip supplied is often too small and
the adhesion insufficient. Use masking tape or another
reflective foil as an alternative. The masking tape or foil
must not be black or have a very dark color.
If a strong gust of wind blows against the window or you
lean against the window and false alarms occur, the
distance of the door/window contact is insufficient. We
recommend a distance of 3 - 5 millimeters. Too tight instal-
lation (e.g. 1 mm) may lead to increased false alarms.
Note: In principle, optical systems can be impaired by
incident external radiation or special optical conditions
(base surface too inclined, etc.). Unfortunately, these
systems cannot be guaranteed to function
