Functions :

Motion Analyzer II Processing

Motion Analyzer II uses multiple thresholds and timing windows to analyze the timing, amplitude, duration, and
polarity of signals to make an alarm decision. It will not alarm extreme levels of thermal and
illumination disturbances caused by heaters and air conditioners, hot and cold drafts, sunlight, lightning,
and moving headlights. Provides three sensitivity settings.

PIR Supervision

PIR supervision provides trouble output if PIR circuitry fails.

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.

Test Features

Three externally visible high-output alarm LEDs are visible
from any angle, flash to indicate a trouble condition.
Internal noise voltage test pins provide precise pattern
location and background disturbance evaluation using
a standard analog meter.
