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.

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.
