The DS860 Series TriTech Detectors with their passive
infrared and microwave processing provide excellent
catch performance with freedom from false alarms.
These surface or corner mount detectors are available
with two different microwave frequencies:

Model

Microwave Frequency

DS860

10.525 GHz

B models

9.9 GHz

Uses passive infrared and microwave technologies to
provide an alarm condition when both fields of
protection are simultaneously activated. Alarm signals
must meet the signaling requirements of both
technologies to activate an alarm.

• PIR Signal Processing: Motion Analyzer II uses

multiple thresholds and timing windows to analyze
timing, amplitude, duration and polarity of signals to
make an alarm decision. Will not alarm on extreme

levels of thermal and illumination disturbances
caused by heaters and air conditioners, hot and cold
drafts, sunlight, lightning, and moving headlights. Two
sensitivity settings are provided.

• Microwave Signal Processing: Pattern recognition

circuitry identifies and ignores repetitive false alarm
sources. Adaptive processing adjusts to background
disturbances. This helps to reduce false alarms while
maintaining catch performance.

Externally visible alarm LED flashes to indicate a
trouble condition.

Patented fully supervised microwave and PIR circuitry
provides single technology coverage in the event the
microwave subsystem fails. Use the memory circuit to
force a self-test at anytime.

The sealed optical chamber provides immunity to
drafts and insects.
