u Five layers of detection including look-down zone
u Supervised microwave and PIR
The DS950 and DS970 Detectors provide excellent
catch performance and freedom from false alarms with
five layers of detection (including look-down zone),
patented passive infrared, and microwave processing.
Functions
Signal Processing
Uses passive infrared and microwave technologies to
provide an alarm condition upon simultaneous
activation of both fields of protection. Adjustable PIR
and microwave sensitivity.
• 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. It will not alarm on extreme
levels of thermal and illumination disturbances
(heaters and air conditioners, hot and cold drafts,
sunlight, lightning, and moving headlights). Motion
Analyzer II provides two sensitivity settings.
• Microwave Signal Processing: Pattern recognition
circuitry identifies and ignores repetitive false alarm
sources. Adaptive processing adjusts to background
disturbances.
u Anti-masking feature
u Selectable PIR sensitivity
u Five mounting options
Microwave Anti-Masking
Provides supervision trouble signal if microwave
reflective material is placed within 30.5 cm (1 ft) of
detector.
Test Features
Three-color alarm LED with separate colors for alarm,
PIR, and microwave activation. Internal noise voltage
test pins provide pattern location and background
disturbance evaluation using a standard analog meter.
Trouble memory feature recalls trouble conditions.
Supervised Microwave and PIR
Patented fully supervised microwave and PIR circuitry
provides single technology coverage in the event the
microwave subsystem fails.
Draft and Insect Immunity
The sealed optic chamber provides immunity to drafts
and insects.
Alarm memory
Provides indication of stored alarms for use in multiple
unit applications by latching the alarm LED. Controlled
by a switched voltage from the control panel.

Microwave Inhibit
When using the memory input, the microwave portion
of the detector can be turned off during disarm period.
Motion Monitor
Switch-selectable one or 30 day Motion Monitor
supervision timers provide the detector with the ability
to verify that there is a clear view of the protection
area. The memory circuit can also control this feature.
