I am with our Abus Secvest 2-way actually very happy. She is 4 years in operation and has already been replaced by a newer with newer software version. The wireless smoke detector, however, are prone to false alarms and power-sapping. After 9 months the first batteries were with us yet. In a later case, we were on vacation, than offset the whole neighborhood, and my parents in the greatest excitement and panic after a week a radio detectors. Now I'll have to send in my Unmounting or Secvest the software update because ABUS knows the problem and on the latest software version that Sevest only triggers when two trigger alarms are sent to the Secvest within a specified period.
