The wall or ceiling mount DS720i TriTech® PIR and
Microwave Detector covers up to 91 m (300 ft).
Motion Monitor and Anti-masking protection provides
coverage integrity. Field replaceable mirrored optics
and three different coverage patterns provide
installation flexibility.
Functions
Alarm Memory
• Indicates stored alarms for use in multiple unit
applications by latching the alarm LED.
• Controlled by a switched voltage from the control
panel.
Signal Processing
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. Adjustable PIR and
microwave sensitivity.
u Motion monitor
u Motion Analyzer II
u Field-changeable mirrored optics
PIR Signal Processing
Uses Motion Analyzer II 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
Uses pattern recognition circuitry to identify and
ignore repetitive false alarm sources. Adaptive
processing adjusts to background disturbances to
reduce false alarms while maintaining catch
performance.
Test Features
High-efficiency walk test LED is visible throughout the
coverage pattern (reducing installation time). LED
flashes to indicate a trouble condition. Internal noise
voltage test pins use standard analog meter to provide
precise pattern location and background disturbance
evaluation. Separate test LEDs for PIR and microwave
activation. Alarm LED can be controlled remotely.

Supervised Microwave and PIR
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.
Anti-masking With Spray Detect
Selectable to provide a microwave supervision trouble
signal if microwave reflective material (metal, wood,
plastics) is placed within 30.5 cm (1 ft) of the
detector. IR Anti-masking feature detects objects
placed to cover the detector or sprayed on the lens
area. Anti-mask sensitivity is selectable, and Anti-mask
activation can be delayed to reduce false alarms.
Motion Monitor
Switch-selectable four or thirty day Motion Monitor
supervision timers provide the detector with the ability
to verify that there is a clear view of the protection
area and that it has not been blocked.
