Functional principle and features
General
FUBW50100 and FUBW50110 are passive infrared (PIR) detectors and are designed for indoor
use. They are suitable for use with the Secvest wireless alarm system and wireless extension of
the Terxon LX and Terxon MX.
The PIR detector reacts to temperature changes.
FUBW50100 has a fan-shaped detection field with a radius of approx. 12 m and aperture angle of
approx. 90°.
FUBW50110 has a fan-shaped detection field with a radius of approx. 9 m and aperture angle of
approx. 90°. FUBW50110 has a lower sensitivity to pets (up to approx. 20 kg) than FUBW50100,
based on a lower sensitivity.
However, this also has an effect on the trigger behaviour in general. The lower sensitivity to e.g.
pets can be explained by lower heat emission
– an adult emits more heat than a pet weighing up
to 20 kg.
Thanks to an internal tamper contact, it is not possible to tamper with the housing of either detector
model or for them to be removed from a wall.
Note
A moulded part in the recess of the back plate serves as an anti-removal wall
contact. This moulded part is mounted to the wall with screws.
If this is not done, tamper detection for the wall is deactivated.
Danger
If the moulded part is not mounted to the wall, the detector will lose its
certification for security level 2.
Main features

design
•
FUBW50110 is less sensitive to pets up to
20 kg
•

For indoor use
Note
FUBW50110
Despite being “animal-proof up to 20 kg,” animals weighing less than this
amount may occasionally trigger the detector. The danger of false triggering is
particularly high if the animal moves, jumps or flies in the vicinity of the detector.
