u 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.

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

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	•	DS7430
•	G Series	•	DS7436
		•	D8125MUX

Notice

The DS7400Xi Series Control Panels require ROM version 1.07 or greater.

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.
