Anti-Crosstalk System
Appropriate models

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.
