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.
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.
Test Features
•
High efficiency LED and light-pipe system provide walk
test indication that is easily viewable from any angle and
at any mounting height.
•
Alarm memory feature allows detector to latch the
alarm LED to aid in response.
•
Remote LED walk-test control allows the LED to be
enabled or disabled using a switched input without
accessing the detector.
