DS778 Long Range
PIR Detector
Features
▶ Motion Analyzer II processing
▶ Pointable mirrored optics
▶ Q-map signal processing
▶ Long range coverage
▶ Four mounting options
The wall mount, long range DS778 PIR Detector uses
Motion Analyzer II signal processing to reduce false alarms.
To aid in walk testing, the DS778 features a high efficiency
alarm LED that is visible throughout the coverage pattern.
This allows one installer to install and test the detector. The
detector's internally pointable optics and mounting options
provide installation flexibility.
Functions
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.
Test Features
The high efficiency alarm LED can be seen throughout the
walk test area. Internal noise voltage test pins provide
precise pattern location and background disturbance
evaluation using a standard analog meter.
Insect and Draft Immunity
The sealed optical chamber provides immunity to drafts and
insects.
