INTRODUCTION
We are very glad for your purchase. The velum DT-AM and velum-C
detectors, due to their small form factor, are particularly suitable for doors
and windows protection; high quality of materials and improved
technology make these detectors appropriate in outdoor environments
where the coverage of defined areas, like vertical walls, is needed. These
detectors implement a curtain coverage with an angle of about 7.5° and
they have a trimmable range up to 12 meters with velum DT-AM and up to
6 meters with velum-C. The fabrication materials are weatherproof and
the plastic housing is sealed. The PCB board is treated with epoxy resin to
ensure its correct working in every humidity and temperature condition.
The accurate design and the digital signal processing of microwave make
these sensors very stable and prevent from false alarms.
The anti-mask process has been implemented using active IR LEDs.
The outdoor curtain velum DT-AM and velum-C detectors are synonym of
reliability and high security, not only from a quality point of view, but also
against sabotage attempts, in fact the anti-tamper reliability is ensured by
a MEMS unit and by a switch against the front opening.
