First Step Processing (FSP)
The ceiling mount DS939 PIR Detector provides a 21 m
(70 ft) panoramic coverage pattern and can be used
on ceilings as high as 7.6 m (25 ft). With three
separate PIR sections that are fully adjustable, the
DS939 provides coverage integrity at all mounting
heights, plus the ability to customize the coverage for
specific areas. The DS939 uses several patented
processing techniques to provide excellent catch
performance with freedom from false alarms.

Functions
Signal Processing
Uses passive infrared technologies to provide an alarm
condition when the field of protection is activated.
Alarm signals must meet the signaling requirements to
activate an alarm.
condition when the field of protection is activated.
Alarm signals must meet the signaling requirements to
activate an alarm.
First Step Processing
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.
