u Motion Analyzer II PIR signal processing
u Linear travel distance (LTD) microwave signal
processing
The OD850 Series TriTech detectors are for use
outdoors and in other harsh environments. They use a
combination of passive- infrared (PIR) and microwave
detection with advanced signal processing.
System overview
The detectors process PIR signals with Motion
Analyzer II signal processing and microwave signals
with Linear Travel Distance (LTD) signal processing.
The detectors can distinguish between small,
repetitive motions such as tree limbs moving in the
wind and the more purposeful motions of intruders.
These advanced processing techniques and the
detectors' mechanical design combine to provide
superior performance in a wide range of weather
conditions.
Functions
Motion Analyzer II Processing
This PIR signal processor uses multiple thresholds and
timing windows to analyze timing, amplitude, duration,
and polarity of signals to make an alarm decision.
Extreme levels of thermal and illumination
disturbances caused by hot and cold drafts, sunlight,
or lightning do not cause an alarm.
u Two sensitivity levels
u Timed relay output adjustable from two sec to 10
min
u AND/OR mode
LTD Microwave Signal Processing
This microwave signal processor measures the linear
travel distance of a target to make an alarm decision.
It eliminates alarms for objects that move but do not
travel, such as tree limbs and hanging signs.
Two Sensitivity Levels
The detectors have two user-selectable PIR sensitivity
settings:
Standard sensitivity is the recommended setting for a
minimum of false alarms. The detector tolerates
environment extremes on this setting.
Intermediate sensitivity is the recommended setting
for any location where an intruder is expected to cover
only a small portion of the protected area. The
detector tolerates normal environments on this
setting. This setting identifies intruders more quickly,
but may produce more false alarms.
Adjustable Timed Relay Output
In addition to an alarm relay, there is a Form C,
unsupervised, timed relay contact that alternates state
1 sec after an alarm and follows a user-selectable
timer. The time expires at the set time after the last
alarm (it resets on each new alarm).

AND/OR Mode
This DIP-switch setting specifies whether the detector
reports alarm situations in the AND mode (when both
technologies simultaneously sense an alarm condition)
or in the OR mode (when either the PIR or microwave
technology senses an alarm state). OR mode provides
faster detection in some conditions as the detector
activates the alarm relay based on a single technology
input.
LEDs
The high-efficiency LEDs (one red and one green) use
the same technology as traffic lights to make them
visible in sunlight. A DIP-switch setting allows the user
to disable these LEDs during standard operation to
save power.
Draft and Insect Immunity
The sealed optical chamber prevents drafts and
insects from affecting the detector.

Mounting Considerations
• Wall Mounting: The OD850 detectors can be mounted
directly on a wall or on the supplied B335 Swivel
Mount Bracket. Alternatively, they can be mounted
directly on a standard rectangular electrical box. The
detectors should be mounted 2.1 m to 2.7 m (7 ft to
9 ft) above the ground. The recommended height is
2.1 m (7 ft); leveled both horizontally and vertically.
• Ceiling Mounting: The detectors can be mounted on a
ceiling using the optional B338 Ceiling-Mount
Bracket.
Power Considerations
• Power Limits: Input power must be provided by an
Approved Limited Power Source. All outputs must be
connected to SELV (safety extra-low voltage) circuits
only.
• Standby Power: This detector has no internal standby
battery. For UL Listed product installations, 4 hr
(248 mAh) of standby power must be supplied by the
control unit or by a UL Listed burglary power supply.
