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.
