The DS825 and DS840 Series Detectors provide immunity
to false alarms caused by pets. Passive infrared and
microwave processing provides excellent catch
performance with freedom from false alarms.
Functions
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.
First Step Processing (FSP)
First Step Processing (FSP) allows virtually instant
response to human targets without sacrificing false alarm
immunity to other sources. By adjusting its sensitivity based
upon signal amplitude, polarity, slope and timing, FSP
eliminates the need for the installer to select the sensitivity
level for the application. Each sensor is processed
individually and both must agree there is an alarm before
the alarm relay is activated.
Microwave Signal Processing
Pattern recognition circuitry identifies and ignores
repetitive false alarm sources. Adaptive processing adjusts
to background disturbances. This helps to reduce false
alarms while maintaining catch performance.
Pet and Animal Immunity
The detector is able to distinguish between signals caused
by humans and signals caused by pets (one dog up to 27 kg
[100 lb], up to 10 cats, and other small animals such as
birds and rodents). This provides immunity to false alarms
while maintaining proper catch performance of human
targets.
Temperature Compensation
The sensor provides compensation at critical temperatures.
Supervised Microwave and PIR
Patented fully supervised microwave and PIR circuitry
provides single technology coverage in the event the
microwave subsystem fails.
Test Features
Externally visible, tricolor alarm LED indicates each
technology independently and flashes to indicate a trouble
condition.
