u Insect and draft immunity
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.
Functions
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
u Three sensitivity settings
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.

Installation/configuration notes
Compatibility Information
Control Panels Multiplex Expansion Modules
• DS7400Xi Series
• G Series
Notice
The DS7400Xi Series Control Panels require ROM
version 1.07 or greater.
• DS7430
• DS7436
• D8125MUX
Mounting Considerations
Select a location that is most likely to intercept an
intruder moving across the coverage pattern. Ensure
the mounting surface is solid and vibration free. Avoid
hot and cold drafts, windows, moisture, direct or
reflected sunlight, and small animals. The MX934i is
not for outdoor mounting.
Notice
Misaligning the detector in an optional mounting
bracket can reduce range and increase dead
zones.
