MX-40QZ/50QZ/40PT
Optex's anti-cross talk system reduces interference effects to the lowest
possible level because this unique technology allows the design of antenna
settings differently from conventional methods.
When several detectors are placed in combination in one area, false alarms
may occur due to matching frequencies, because microwaves from each detector
may cause interference with each other. But Anti-Crosstalk System greatly
reduces interference to prevent false alarms.
Sensor with Anti-Crosstalk System
The microwave antenna of our MX-series sensors are tilted at 45° so that
MX sensors installed vis-á-vis in the same room may have polarization
planes crossing each other at 90°. This liberates both sensors from interference
from the other sensor. Likewise, MX sensors fixed back to back (or vis-á-vis)
in adjacent rooms may also be free from mutual microwave interference because
their polarization planes cross each other at 90°.
The polarization plane of microwaves emitted from one sensor differs from that of microwaves coming from the other sensor. This sets both sensors free from mutual interference.
