Bosch MX775i Multiplex PIR Intrusion Detector Bosch MX934i Multiplex PIR Intrusion Detector
MX775i Multiplex PIR Intrusion Detector Provides a tamper switch, movable mirrors, and selectable sensitivity.

The MX775i is a PIR intrusion detector that provides a variety of coverage patterns through the use of interchangeable mirrors and the choice of mirror angle settings. It is designed to be surface or corner mounted, but can be mounted with any of three optional brackets. This provides further flexibility in aiming the detector. It is designed to connect to the Multiplex Bus of a control panel and optionally to an auxiliary 12 VDC power source. It is compatible with the DS7400Xi Series Control Panels with a DS7430 or DS7436 Multiplex Expansion Module or with GV2 and G Series Control Panels with a D8125MUX Module installed.
Note The DS7400 and DS7400Xi require ROM version 1.07 or greater.

  • Interchangeable, pointable mirrors
  • Selectable sensitivity
  • Built-in tamper switch

    Interchangeable, Pointable Mirrors - The detector comes with a standard broad pattern mirror and two optional mirrors are available: a long-range pattern mirror and a barrier pattern mirror. To change the mirror, pull it out from its resting grooves. To adjust the mirror vertically (from +1° to -18°) slide the mirror forward or back. To adjust the mirror horizontally (±10°) rock the mirror from side to side.

    Three Sensitivity Settings Selectable for Standard, Intermediate or High:

    • Standard: Recommended setting for maximum false alarm immunity. Tolerates environment extremes on this setting. Not recommended for Long Range or Barrier type patterns. The detector is shipped in Standard Sensitivity mode.

    • Intermediate: Recommended setting for any location where an intruder is expected to cover only a small portion of the protected area. Tolerates normal environments on this setting. This setting will improve your intruder catch performance.

    • High: Fast response to intruder signals. For use in quiet environments where thermal and illumination transients are not anticipated.

    Internal Tamper Switch - The internal tamper switch sends a signal to the control panel's Multiplex Bus for display at the keypads when the detector's cover is removed.

  • MX934i Multiplex PIR Intrusion Detector Provides Motion Analyzer II processing, unique address switch settings, insect and draft immunity, and three sensitivity settings.
    The wall mount MX934i PIR Intrusion Detector uses Motion Analyzer II signal processing to reduce false alarms. Alarm and tamper conditions are transmitted to the control panel through the two-wire multiplex bus. The detector’s replaceable and pointable mirrors, three coverage patterns, and three mounting options provide installation flexibility.
  • Motion Analyzer II processing
  • Unique address switch settings
  • Insect and draft immunity
  • Three sensitivity settings

    Motion Analyzer II Processing Motion Analyzer II uses multiple thresholds and timing windows to analyze timing, amplitude, duration, and polarity of signals to make an alarm decision. It tolerates extreme levels of heat and light disturbances caused by heaters and air conditioners, hot and cold drafts, sunlight, lightning, and moving headlights.

    Insect and Draft Immunity The sealed optical chamber provides immunity to drafts and insects.

    Three Sensitivity Settings

    • Standard Sensitivity: Recommended setting for maximum false alarm immunity. Tolerates environment extremes on this setting. Not recommended for long range or barrier type coverage patterns. The detector is shipped in Standard Sensitivity mode.

    • Intermediate Sensitivity: Recommended setting for any location where an intruder is expected to cover only a small portion of the protected area. Tolerates normal environments on this setting. This setting identifies intruders more accurately.

    • High Sensitivity: Fast response to intruder signals. For use in quiet environments where heat and light fluctuations are not anticipated.
