Data sheet


  • Sealed Optics
    The sealed optical chamber prevents drafts and insects from affecting the detector.
  • Uniform Sensitivity Optics
    Whether an intruder is directly in front of the sensor or at the edge of a protected area, the custom designed Fresnel lens provides a consistent level of detection—delivering optimal performance no matter what the distance. Shorter precision focal lengths mean superior optics and detection.
  • Wall-to-Wall Coverage
    Wide and long detection coverage for coverage range protection that exceeds similar products in the market.
  • Superior Detection and False Alarm Immunity
    The IS335 motion detector provides superior protection against false alarms without sacrificing catch performance.
  • Pet‑friendly Selectivity
    Installers can turn pet immunity on or off simply by setting a jumper. When pet immunity is enabled, the detector can distinguish between signals caused by humans while ignoring pets up to 80 lbs.
  • PIR White Light Immunity
    A patented black bug guard reduces false alarms by providing 2,000 lux of white light immunity. This helps reduce false alarm problems caused by lights, flashlights or reflective objects.
  • Flexible Mountings
    The IS335 motion detector mounts on walls or in corners, with heights from 7 ft - 9 ft (2.1 m - 2.7 m).
