Intelligent processing routines in the enhanced Matchtec algorithm provide high detection reliability and false alarm immunity. The algorithm analyzes the relative strength of the IR and MW signals received from a moving object in order to make sound decisions. It is even possible to use multiple detectors in close proximity to each other, since the algorithm reduces interference between the MW modules. This increases flexibility in selecting the installation site.

The detectors have a future-proof design. Compared to earlier models, they can withstand higher MW radiation and field strengths. As a result, they comply with the new, significantly more demanding CE regulations that have come into force in June 2014.

The detectors are suitable for both home and commercial environments and perform well even under harsh conditions, such as in rooms with rapid and extreme temperature fluctuations that can create false alarms.

The detectors feature a modern, slim design and can thus be installed unobtrusively even in rooms where an attractive appearance is important. The 12 m version can also be flush-mounted. The same bracket is used for mounting on walls and ceilings, which facilitates installation and storage.

Developed by the Siemens Security Products business unit, the detectors offer a wide range of benefits for installers. Due to preconfigured end of line (EoL) resistors, they are ready for use with Siemens alarm panels such as SPC and Sintony. EoL modules make it easy to connect the detectors to alarm panels of other manufacturers without errors. Automatic walktest mode allows the detector to remain in this mode for three minutes after power-on, which saves time since all walktests can be carried out without opening the detector multiple times or changing DIP switches.
